SERVIC. MANUA. MODELS Mercury/Mariner 4 · 5 V 6 (4-Stroke) Starting Serial Numbers 0R000001 and Above Printed in U.S.A. W2000, Mercury Marine 90-857138R1 MAY 2000 Notice Throughout this publication, “Dangers”, “Warnings” and “Cautions” (accompanied by the International HAZARD Symbol ) are used to alert the mechanic to special instructions concerning a particular service or operation that may be hazardous if performed incorrectly or carelessly. OBSERVE THEM CAREFULLY! These “Safety Alerts” alone cannot eliminate the hazards that they signal. Strict compliance to these special instructions when performing the service, plus “Common Sense” operation, are major accident prevention measures. DANGER DANGER - Immediate hazards which WILL result in severe personal injury or death. WARNING WARNING -Hazards or unsafe practices which COULD result in severe personal injury or death. CAUTION Hazards or unsafe practices which could result in minor personal injury or product or property damage. Notice to Users of This Manual This service manual has been written and published by the Service Department of Mercury Marine to aid our dealers’ mechanics and company service personnel when servicing the products described herein. It is assumed that these personnel are familiar with the servicing procedures of these products, or like or similar products manufactured and marketed by Mercury Marine, that they have been trained in the recommended servicing procedures of these products which includes the use of mechanics’ common hand tools and the special Mercury Marine or recommended tools from other suppliers. We could not possibly know of and advise the service trade of all conceivable procedures by which a service might be performed and of the possible hazards and/or results of each method. We have not undertaken any such wide evaluation. Therefore, anyone who uses a service procedure and/or tool, which is not recommended by the manufacturer, first must completely satisfy himself that neither his nor the products safety will be endangered by the service procedure selected. All information, illustrations and specifications contained in this manual are based on the latest product information available at the time of publication. As required, revisions to this manual will be sent to all dealers contracted by us to sell and/or service these products. It should be kept in mind, while working on the product, that the electrical system and ignition system are capable of violent and damaging short circuits or severe electrical shocks. When performing any work where electrical terminals could possibly be grounded or touched by the mechanic, the battery cables should be disconnected at the battery. Any time the intake or exhaust openings are exposed during service they should be covered to protect against accidental entrance of foreign material which could enter the cylinders and cause extensive internal damage when the engine is started. 90-857138R1 MAY 2000 Page i It is important to note, during any maintenance procedure replacement fasteners must have the same measurements and strength as those removed. Numbers on the heads of the metric bolts and on the surfaces of metric nuts indicate their strength. American bolts use radial lines for this purpose, while most American nuts do not have strength markings. Mismatched or incorrect fasteners can result in damage or malfunction, or possibly personal injury. Therefore, fasteners removed should be saved for reuse in the same locations whenever possible. Where the fasteners are not satisfactory for re-use, care should be taken to select a replacement that matches the original. Cleanliness and Care of Outboard Motor A marine power product is a combination of many machined, honed, polished and lapped surfaces with tolerances that are measured in the ten thousands of an inch/mm. When any product component is serviced, care and cleanliness are important. Throughout this manual, it should be understood that proper cleaning, and protection of machined surfaces and friction areas is a part of the repair procedure. This is considered standard shop practice even if not specifically stated. Whenever components are removed for service, they should be retained in order. At the time of installation, they should be installed in the same locations and with the same mating surfaces as when removed. Personnel should not work on or under an outboard which is suspended. Outboards should be attached to work stands, or lowered to ground as soon as possible. We reserve the right to make changes to this manual without prior notification. Refer to dealer service bulletins for other pertinent information concerning the products described in this manual. Page Numbering Two number groups appear at the bottom of each page. The example below is self-explanatory.

Check engine oil level. 2. Visually inspect the fuel system for deterioration or leaks. 3. Check outboard for tightness on transom. 4. Check propeller blades for damage. After Each Use 1. Flush out the outboard cooling system if operating in salt or polluted water. 2. Wash off all salt deposits and flush out the exhaust outlet of the propeller and gear case with fresh water if operating in salt water. Every 100 Hours of Use or Once Yearly, Whichever Occurs First 1. Lubricate all lubrication points. Lubricate more frequently when used in salt water. 2. Change engine oil. The oil should be changed more often when the engine is operated under adverse conditions such as extended trolling. 3. Inspect and clean spark plugs. 4. Check fuel line filter for contaminants. 5. Check corrosion control anode. Check more frequently when used in salt water. 6. Drain and replace gear case lubricant. 7. Lubricate splines on the drive shaft.* 8. Check tightness of bolts, nuts, and other fasteners. 9. Replace water pump impeller.* * These items should be serviced by an authorized dealer. 90-857138R1 MAY 2000 Page 1B-3 MAINTENANCE Flushing The Cooling System Flush the internal water passages of the outboard with fresh water after each use in salt, polluted, or muddy water. This will help prevent a buildup of deposits from clogging the internal water passages. NOTE:Do not run the engine while flushing the cooling system. 1. Remove plug and gasket and thread-in hose coupling. 2. Attach a water hose to the hose coupling. Turn on the water gently and flush the cooling system for 3 to 5 minutes. 3. Remove the thread-in hose coupling and reinstall plug and gasket. b a a-Plug and Gasket b-Hose Coupling Fuel System WARNING Avoid serious injury or death from gasoline fire or explosion. Carefully follow all fuel system service instructions. Always stop the engine and DO NOT smoke or allow open flames or sparks in the area while servicing any part of the fuel system. Before servicing any part of the fuel system, stop engine and disconnect the battery. Drain the fuel system completely. Use an approved container to collect and store fuel. Wipe up any spillage immediately. Material used to contain spillage must be disposed of in an approved receptacle. Any fuel system service must be performed in a well ventilated area. Inspect any completed service work for sign of fuel leakage. Fuel Line Inspection Visually inspect the fuel line and primer bulb for cracks, swelling, leaks, hardness or other signs of deterioration or damage. If any of these conditions is found, the fuel line or primer bulb must be replaced. Engine Fuel Filter Inspect the fuel line filter. If the filter appears to be contaminated, remove and replace. Page 1B-4 90-857138R1 MAY 2000 MAINTENANCE Corrosion Control Anode Your outboard has a corrosion control anode installed to the gear case. An anode helps protect the outboard against galvanic corrosion by sacrificing its metal to be slowly eroded instead of the outboard metals. The anode requires periodic inspection especially in salt water which will accelerate the erosion. To maintain this corrosion protection, always replace the anode before it is completely eroded. Never paint or apply a protective coating on the anode as this will reduce effectiveness of the anode. a a-Anode Spark Plug Inspection Inspect spark plugs at the recommended intervals. 1. Remove the spark plug leads by twisting the rubber boots slightly and pull off. 2. Remove the spark plugs to inspect and clean. Replace spark plug if electrode is worn or the insulator is rough, cracked, broken, blistered or fouled. 3. Set the spark plug gap. See Specification Chart in General Information Section. 4. Before reinstalling spark plugs, clean away dirt on the spark plug seats.

(195 mL) When adding or changing gear case lubricant, visually check for the presence of water in the lubricant. If water is present, it may have settled to the bottom and will drain out prior to the lubricant, or it may be mixed with the lubricant, giving it a milky colored appearance. If water is noticed, have the gear case checked by your dealer. Water in the lubricant may result in premature bearing failure or, in freezing temperatures, will turn to ice and damage the gear case. Also examine the gear case lubricant for metal particles. A small amount of metal filings or fine metal particles indicates normal gear wear. An excessive amount of metal filings or larger particles (chips) may indicate abnormal gear wear and should be checked by an authorized dealer. Draining Gear Case 1. Place outboard in a vertical operating position. 2. Place drain pan below outboard. 3.

If the gasoline being used contains alcohol, it is advisable to drain as much of the remaining gasoline as possible from the fuel tank, remote fuel line, and engine fuel system. Fill the fuel system (tank, hoses, fuel pumps, and fuel injection systems) with treated (stabilized) fuel to help prevent formation of varnish and gum. Proceed with following instructions. 1. Portable Fuel Tank – Pour the required amount of Quicksilver Gasoline Stabilizer (follow instructions on container) into fuel tank. Tip fuel tank back and forth to mix stabilizer with the fuel. 2. Permanently Installed Fuel Tank – Pour the required amount of Quicksilver Gasoline Stabilizer (follow instructions on container) into a separate container and mix with approximately one quart (one liter) of gasoline. Pour this mixture into fuel tank. 3. Place the outboard in water or connect flushing attachment for circulating cooling water. Run the engine for ten minutes to allow treated fuel to fill the fuel system. Protecting External Engine Components 1. Lubricate all outboard components listed in the Inspection and Maintenance Schedule. 2. Touch up any paint nicks. 3. Spray Quicksilver Corrosion Guard on external metal surfaces (except corrosion control anodes). Page 1B-10 90-857138R1 MAY 2000 MAINTENANCE 90-857138R1 MAY 2000 Page 1B-11 Protecting Internal Engine Components NOTE: Before performing Steps 1 and 2, make sure the fuel system has been prepared for storage. 1. Change the engine oil. 2. Place the outboard in water or connect flushing attachment for circulating cooling water. Start the engine and let it run in neutral to warm up. 3. With engine running at fast idle, stop the fuel flow by disconnecting the remote fuel line. When engine begins to stall, quickly spray Quicksilver Storage Seal into carburetor until engine stops from lack of fuel. 4. Remove the spark plugs and inject a five second spray of Quicksilver Storage Seal around the inside of each cylinder. 5. Rotate the flywheel manually several times to distribute the storage seal in the cylinders. Reinstall spark plugs. Gear Case Drain and refill the gear case lubricant (refer to maintenance procedure). Positioning Outboard for Storage 1. Carry, transport or store the outboard only in these two positions. These positions will prevent oil from draining out of the crankcase. a. Upright b. Tiller Side Down a b 2. Never carry, store or transport the outboard in these positions. Engine damage could result from oil draining out of the crankcase. CAUTION If outboard is on a boat and is stored tilted up in freezing temperature, trapped cooling water or rain water that may have entered the propeller exhaust outlet in the gear case could freeze and cause damage to the outboard.

Therefore, established horsepower ratings refer to the power that the engine will produce at its rated rpm under a specific combination of weather conditions. Corporations internationally have settled on adoption of I.S.O. (International Standards Organization) engine test standards, as set forth in I.S.O. 3046 standardizing the computation of horsepower from data obtained on the dynamometer, correcting all values to the power that the engine will produce at sea level, at 30% relative humidity at 77° F (25° C) temperature and a barometric pressure of 29.61 inches of mercury. Page 1C-2 90-857138R1 MAY 2000 GENERAL INFORMATION Summer Conditions of high temperature, low barometric pressure and high humidity all combine to reduce the engine power. This, in turn, is reflected in decreased boat speeds--as much as 2 or 3 miles-per-hour (3 or 5 Km per-hour) in some cases. (Refer to previous chart.) Nothing will regain this speed for the boater, but the coming of cool, dry weather. In pointing out the practical consequences of weather effects, an engine--running on a hot, humid summer day--may encounter a loss of as much as 14% of the horsepower it would produce on a dry, brisk spring or fall day. The horsepower, that any internal combustion engine produces, depends upon the density of the air that it consumes and, in turn, this density is dependent upon the temperature of the air, its barometric pressure and water vapor (or humidity) content. Accompanying this weather-inspired loss of power is a second but more subtle loss. At rigging time in early spring, the engine was equipped with a propeller that allowed the engine to turn within its recommended rpm range at full throttle. With the coming of the summer weather and the consequent drop in available horsepower, this propeller will, in effect, become too large. Consequently, the engine operates at less than its recommended rpm. Due to the horsepower/rpm characteristics of an engine, this will result in further loss of horsepower at the propeller with another decrease in boat speed. This secondary loss, however, can be regained by switching to a smaller pitch propeller that allows the engine to again run at recommended rpm. For boaters to realize optimum engine performance under changing weather conditions, it is essential that the engine have the proper propeller to allow it to operate at or near the top end of the recommended maximum rpm range at wide-open-throttle with a normal boat load. Not only does this allow the engine to develop full power, but equally important is the fact that the engine also will be operating in an rpm range that discourages damaging detonation. This, of course, enhances overall reliability and durability of the engine. Boat WEIGHT DISTRIBUTION 1. Proper positioning of the weight inside the boat (persons and gear) has a significant effect on the boat’s performance, for example: a. Shifting weight to the rear (stern). (1.) Generally increases top speed. (2.) If in excess, can cause the boat to porpoise. (3.) Can make the bow bounce excessively in choppy water. (4.) Will increase the danger of the following - wave splashing into the boat when coming off plane. b. Shifting weight to the front (bow). c. Adjusting tilt pin to achieve best performance and handling. (1.) Improves ease of planing off. (2.) Generally improves rough water ride. (3.) If excessive, can make the boat veer left and right (bow steer). BOTTOM For maximum speed, a boat bottom should be nearly a flat plane where it contacts the water and particularly straight and smooth in fore-and-aft direction. 90-857138R1 MAY 2000 Page 1C-3 GENERAL INFORMATION 1. Hook: Exists when bottom is concave in fore-and-aft direction when viewed from the side. When boat is planing, “hook” causes more lift on bottom near transom and allows bow to drop, thus greatly increasing wetted surface and reducing boat speed. “Hook” frequently is caused by supporting boat too far ahead of transom while hauling on a trailer or during storage. 2. Rocker: The reverse of hook and much less common. “Rocker” exists if bottom is convex in fore-and-aft direction when viewed from the side, and boat has strong tendency to porpoise. 3. Surface Roughness: Moss, barnacles, etc., on boat or corrosion of outboard’s gear housing increase skin friction and cause speed loss. Clean surfaces when necessary. WATER ABSORPTION It is imperative that all through hull fasteners be coated with a quality marine sealer at time of installation. Water intrusion into the transom core and/or inner hull will result in additional boat weight (reduced boat performance), hull decay and eventual structural failure. CAVITATION Cavitation is caused by water vapor bubbles forming either from a sharp edge or angle on the gear case, from an irregularity in the propeller blade itself or from improper engine installation (too high). These vapor bubbles flow back and collapse when striking the surface of the propeller blade resulting in the erosion of the propeller blade surface. If allowed to continue, eventual blade failure (breakage) will occur. Page 1C-4 90-857138R1 MAY 2000 GENERAL INFORMATION Engine DETONATION Detonation in a 4-cycle engine resembles the “pinging” heard in an automobile engine. It can be otherwise described as a tin-like “rattling” or “plinking” sound. Detonation is an explosion of an unburned portion of the fuel/air charge after the spark plug has fired. Detonation creates severe shock waves in the engine, and these shock waves often find or create a weakness: The dome of a piston, cylinder head/gasket, piston rings or piston ring lands, piston pin and bearings. A few of the most common causes of detonation in a marine 4-cycle application are as follows: • Over-advanced ignition timing. • Use of low octane gasoline. • Propeller pitch too high (engine rpm below recommended maximum range). • Lean fuel mixture at or near wide-open-throttle. • Spark plugs (heat range too hot - incorrect reach - cross-firing). • Inadequate engine cooling (deteriorated cooling system). • Combustion chamber/piston deposits (result in higher compression ratio). Detonation usually can be prevented if: 1. The engine is correctly set up. 2. Diligent maintenance is applied to combat the detonation causes. 51115 Damaged Piston Resulting from Detonation 90-857138R1 MAY 2000 Page 1C-5 GENERAL INFORMATION Following Complete Submersion Submerged While Running (Special Instructions) When an engine is submerged while running, the possibility of internal engine damage is greatly increased. If, after engine is recovered and with spark plugs removed, engine fails to turn over freely when turning flywheel, the possibility of internal damage (bent connecting rod and/or bent crankshaft) exists. If this is the case, the powerhead must be disassembled. Salt Water Submersion (Special Instructions) Due to the corrosive effect of salt water on internal engine components, complete disassembly is necessary before any attempt is made to start the engine. Fresh Water Submersion (Special Instructions) 1. Recover engine as quickly as possible. 2. Remove cowling. 3. Flush exterior of outboard with fresh water to remove mud, weeds, etc. DO NOT attempt to start engine if sand has entered powerhead, as powerhead will be severely damaged. Disassemble powerhead if necessary to clean components. 4. Drain engine oil. Do not refill engine oil at this time. 5. Drain carburetor and clean fuel pump assembly. 6. Remove spark plug and get as much water as possible out of powerhead. Most water can be eliminated by placing engine in a horizontal position (with spark plug holes down) and rotating flywheel. 7. Pour alcohol into carburetor throat (alcohol will absorbed water). Again rotate flywheel. 8. Turn engine over and pour alcohol into spark plug opening and rotate flywheel. 9. Turn engine over (place spark plug openings down) and pour engine oil into throat of carburetor while rotating flywheel to distribute oil throughout crankcase. 10. Again turn engine over and pour approximately one teaspoon of engine oil into spark plug opening. Again rotate flywheel to distribute oil in cylinder. 11. Dry all wiring and electrical components using compressed air. 12. Reinstall spark plug. 13. Refill engine crankcase with fresh oil. 14. Attempt to start engine, using a fresh fuel source. If engine starts, it should be run for at least one hour to eliminate any water in engine. 15. If engine fails to start, determine cause (fuel, electrical or mechanical). Engine should be run within 2 hours after recovery of outboard from water, or serious internal damage may occur. If unable to start engine in this period, disassemble engine and clean all parts. Apply oil as soon as possible. Page 1C-6 90-857138R1 MAY 2000 GENERAL INFORMATION Propeller Selection For in-depth information on marine propellers and boat performance - written by marine engineers - see your Authorized Dealer for the illustrated “What You Should Know About Quicksilver Propellers...and Boat Performance Information” (Part No. 90-86144). For best all around performance from your outboard/boat combination, select a propeller that allows the engine to operate in the upper half of the recommended full throttle rpm range with the boat normally loaded (refer to Specifications). This rpm range allows for better acceleration while maintaining maximum boat speed. If changing conditions cause the rpm to drop below the recommended range (such as warmer, more humid weather, operation at higher elevations, increased boat load or a dirty boat bottom/gear case) a propeller change or cleaning may be required to maintain performance and ensure the outboard’s durability. Check full-throttle rpm using an accurate tachometer with the engine trimmed out to a balanced- steering condition (steering effort equal in both directions) without causing the propeller to “break loose”. Refer to “Quicksilver Accessory Guide” for a complete list of available propellers. 1. Select a propeller that will allow the engine to operate at or near the top of the recommended full throttle rpm range (listed in “Specifications,” preceding) with a normal load. Maximum engine speed (rpm) for propeller selection exists when boat speed is maximum and trim is minimum for that speed. (High rpm, caused by an excessive trim angle, should not be used in determining correct propeller.) Normally, there is a 150-350 rpm change between propeller pitches. 2. If full throttle operation is below the recommended range, the propeller MUST BE changed to one with a lower pitch to prevent loss of performance and possible engine damage. 3. After initial propeller installation, the following common conditions may require that the propeller be changed to a lower pitch: a. Warmer weather and great humidity will cause an rpm loss. b. Operating in a higher elevation causes an rpm loss. c. Operating with a damaged propeller or a dirty boat bottom or gear housing will cause an rpm loss. d. Operation with an increased load (additional passengers, equipment, pulling skiers, etc.). 90-857138R1 MAY 2000 Page 1C-7 GENERAL INFORMATION Propeller Removal/Installation WARNING If the propeller shaft is rotated while the engine is in gear, there is the possibility that the engine will crank over and start. To prevent this type of accidental engine starting and possible serious injury caused from being struck by a rotating propeller, always shift outboard to neutral position and remove spark plug leads when you are servicing the propeller 1. Remove the spark plug leads to prevent engine from starting. 2. Shift outboard to neutral position. N 3. Straighten and remove cotter pin. a a-Cotter Pin 4. Place a block of wood between gear case and propeller to hold propeller and remove propeller nut. a b a-Block of Wood b-Propeller Nut Page 1C-8 90-857138R1 MAY 2000 GENERAL INFORMATION 5. Pull propeller straight off shaft. If propeller is seized to the shaft and cannot be removed, have the propeller removed by an authorized dealer. a b a-Propeller b-Propeller Nut 6. Coat the propeller shaft with Quicksilver Anti-Corrosion Grease or 2-4-C Marine Lubricant with Teflon. IMPORTANT: To prevent the propeller hub from corroding and seizing to the propeller shaft, especially in salt water, always apply a coat of the recommended lubricant to the entire propeller shaft at the recommended maintenance intervals and also each time the propeller is removed. 7. Install front thrust washer, propeller, rear thrust hub and propeller nut onto the shaft. 8. Place a block of wood between gear case and propeller to prevent rotation and tighten propeller nut. Secure propeller nut to the shaft with cotter pin. e d c b a a-Front Thrust Washer b-Propeller c-Rear Thrust Hub d-Propeller Nut e-Cotter Pin 90-857138R1 MAY 2000 Page 1C-9 GENERAL INFORMATION Compression Check 1. Remove spark plugs. 2. Install compression gauge in spark plug hole. 3. Hold throttle plate at W.O.T. 4. Crank the engine over until the compression reading peaks on the gauge. Record the reading. 5. Check and record compression of cylinder. A reading below 36 psi might indicate a total engine wear problem. Maximum (psi)* Minimum (psi)* 50 36 *Compression listed above is with decompression assembly in operation. Maximum (psi)* Minimum (psi)* 130 100 *Compression listed above is with decompression assembly not in operation. (Rocker arm on exhaust side is removed) 6. Compression check is important because an engine with low compression cannot be tuned successfully to give peak performance. It is essential, therefore, that improper compression be corrected before proceeding with an engine tuneup. 7. Cylinder scoring: If powerhead shows any indication of overheating, such as discolored or scorched paint, visually inspect cylinder for scoring or other damage as outlined in Section 4 “Powerhead.” Page 1C-10 90-857138R1 MAY 2000 GENERAL INFORMATION Cylinder Leakage Testing NOTE:Cylinder leakage testing*, along with compression testing, can help the mechanic pinpoint the source of a mechanical failure by gauging the amount of leakage in an engine cylinder. Refer to the manufactures tester instructions for proper testing procedures. * Courtesy of Snap-On-Tools Cylinder Leakage Tester (Snap-On-Tools MT324) NOTE: Spark plug hole is a 12 mm diameter. Use Snap-On Tool MT26-18 adapter with valve core removed. Analysis Due to standard engine tolerances and engine wear, no cylinder will maintain a 0% of leakage. It is important only that cylinders have somewhat consistent reading between them. Differences of 15 to 30% indicate excessive leakage. Larger engines tend to have a larger percentage of cylinder leakage than smaller engines. If excessive leakage is present, first check that the piston is at top dead center of it’s compression stroke. Leakage will naturally occur if the exhaust or intake valve is open. To determine the cause of high percentage leaks, you must locate where the air is escaping from. Listen for air escaping thru the carburetor intake, adjacent spark plug holes, exhaust pipe, crankcase fill plug. Use the following table to aid in locating the source of cylinder leakage: Air Escaping From: Indicates Possible Defective: Carburetor Intake Valve Exhaust System Exhaust Valve Crankcase Fill Plug Piston or Rings Cylinder Head Gasket 90-857138R1 MAY 2000 Page 1C-11 GENERAL INFORMATION Painting Procedures Cleaning & Painting Aluminum Propellers & Gear Housings WARNING Avoid serious injury from flying debris. Avoid serious injury from airborne particles. Use eye and breathing protection with proper ventilation. PROPELLERS 1. Sand the entire area to be painted with 3M 120 Regalite Polycut or coarse Scotch-Brite, disc or belts. 2. Feather edges of all broken paint edges. Try not to sand through the primer. 3. Clean the surface to be painted using PPG Industries DX330 Wax and Grease Remover or equivalent (Xylene or M.E.K.). 4. If bare metal has been exposed, use Quicksilver’s Light Gray Primer. 5. Allow a minimum of 1 hour dry time and no more than 1 week before applying the finish coat. 6. Apply the finish coat using Quicksilver’s EDP Propeller Black. GEAR HOUSINGS The following procedures should be used in refinishing gear housings. This procedure will provide the most durable paint system available in the field. The materials recommended are of high quality and approximate marine requirements. The following procedure will provide a repaint job that compares with a properly applied factory paint finish. It is recommended that the listed materials be purchased from a local Ditzler Automotive Finish Supply Outlet. The minimum package quantity of each material shown following is sufficient to refinish several gear housings. Procedure: 1. Wash gear housing with a muriatic acid base cleaner to remove any type of marine growth, and rinse with water, if necessary. 2. Wash gear housing with soap and water, then rinse. 3. Sand blistered area with 3M 180 grit sandpaper or P180 Gold Film Disc to remove paint blisters only. Feather edge all broken paint edges. 4. Clean gear housing thoroughly with (DX-330) wax and grease remover. 5. Spot repair surfaces where bare metal is exposed with (DX-503) alodine treatment. IMPORTANT: Do not use any type of aerosol spray paints as the paint will not properly adhere to the surface nor will the coating be sufficiently thick to resist future paint blistering. 6. Mix epoxy chromate primer (DP-40) with equal part catalyst (DP-401) per manufacturers instructions, allowing proper induction period for permeation of the epoxy primer and catalyst. 7. Allow a minimum of one hour drying time and no more than one week before top coating assemblies. 8. Use Ditzler Urethane DU9000 for Mercury Black, DU34334 for Mariner Grey, and DU35466 for Force Charcoal, and DU33414M for Sea Ray White. Catalyze all four colors with Ditzler DU5 catalyst mixed 1:1 ratio. Reduce with solvents per Ditzler label. Page 1C-12 90-857138R1 MAY 2000 GENERAL INFORMATION CAUTION Be sure to comply with instructions on the label for ventilation and respirators. Using a spray gun, apply one half to one mil even film thickness. Let dry, flash off for five minutes and apply another even coat of one half to one mil film thickness. This urethane paint will dry to the touch in a matter of hours, but will remain sensitive to scratches and abrasions for a few days. 9. The type of spray gun used will determine the proper reduction ratio of the paint. IMPORTANT: Do not paint sacrificial zinc trim tab or zinc anode. 10. Cut out a cardboard “plug” for trim tab pocket to keep paint off of mating surface to maintain good continuity circuitry between trim tab and gear housing. Decal Application Decal Removal 1. Mark decal location before removal to assure proper alignment of new decal. 2. Carefully soften decal and decal adhesive with a heat gun or heat blower while removing old decal. 3. Clean decal contact area with a 1:1 mixture of isopropyl alcohol and water. 4. Thoroughly dry decal contact area and check for a completely cleaned surface.

Measure the transom height of your boat. The boat bottom should be aligned or be within 1 in. (25 mm) above the anti-ventilation plate of the outboard. 1-2 in. (25 - 50 mm) a a-Anti-Ventilation Plate 2. Place outboard on center line of transom. 3. Tighten transom clamp handles. 90-857138R1 MAY 2000 Page 1D-3 OUTBOARD MOTOR INSTALLATION Fastening Security Line WARNING If the length of security line being used is long enough to allow the outboard to disengage off the boat transom but is too short to not allow the outboard to submerge behind the boat and stop running, the outboard could continue running and propel itself back into the boat with the propeller rotating under power. This exposes the occupants to serious injury or death. The primary purpose for installing a security line is to prevent loss of the outboard if the outboard becomes detached from the boat transom. An effective security line should be of a working strength of at least five times the weight of the outboard. The security line should be attached between the boat and outboard following one of these steps. Step 1. The length of the security line should be short enough and affixed in a manner to prevent the outboard from rising up and disengaging off the boat transom. Step 2. The length of the security line should be long enough and affixed in a manner to permit a detached outboard to submerge completely behind the boat and stop running but not too short that could allow the outboard to continue running and propel itself back into the boat. Tilt Pin Adjustment Setting The Operating Angle Of Your Outboard 1. The vertical operating angle of your outboard is adjusted by changing the position of the tilt pin in the adjustment holes provided. Proper adjustment allows the boat to run stable, achieve optimum performance, and minimize steering effort. a a-Tilt Pin 2. The tilt pin should be adjusted so the outboard is positioned to run perpendicular to the water when the boat is running at full speed. This allows the boat to be driven parallel to the water. 3. Arrange passengers and load in the boat so the weight is distributed evenly. Page 1D-4 90-857138R1 MAY 2000 OUTBOARD MOTOR INSTALLATION Engine Over-Speed Protection System The system is activated if the engine speed should ever exceed the maximum allowable limit. This will protect the engine from mechanical damage. Anytime the engine over-speed system is activated, the system will automatically reduce the engine speed to within the allowable limit. If engine over-speed continues, have the outboard checked by your dealer. NOTE:Your engine speed should never reach the maximum limit to activate the system unless the propeller is ventilating, an incorrect propeller is being used, or the propeller is faulty.

Emissions are what comes out of the exhaust system in the exhaust gas when the engine is running. They are formed as a result of the process of combustion or incomplete combustion. To understand exhaust gas emissions, remember that both air and fuel are made of several elements. Air contains oxygen and nitrogen among other elements; gasoline contains mainly hydrogen and carbon. These four elements combine chemically during combustion. If combustion were complete, the mixture of air and gasoline would result in these emissions: water, carbon dioxide and nitrogen, which are not harmful to the environment. But combustion is not usually complete. Also, potentially harmful gases can be formed during and after combustion. All marine engines must reduce the emission of certain pollutants, or potentially harmful gases, in the exhaust to conform with levels legislated by the EPA. Emissions standards become more stringent each year. Standards are set primarily with regard to three emissions: hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx). Hydrocarbons – HC Gasoline is a hydrocarbon fuel. The two elements of hydrogen and carbon are burned during combustion in combination with oxygen. But they are not totally consumed. Some pass through the combustion chamber and exit the exhaust system as unburned gases known as hydrocarbons. Carbon Monoxide – CO Carbon is one of the elements that make up the fuel burned in the engine along with oxygen during the combustion process. If the carbon in the gasoline could combine with enough oxygen (one carbon atom with two oxygen atoms), it would come out of the engine in the form of carbon dioxide (CO2). CO2 is a harmless gas. But carbon often combines with insufficient oxygen (one carbon atom with one oxygen atom). This forms carbon monoxide, CO. Carbon monoxide is the product of incomplete combustion and is a dangerous, potentially lethal gas. Oxides of Nitrogen - NOx NOx is a slightly different byproduct of combustion. Nitrogen is one of the elements that makes up the air going into the engine. Under extremely high temperatures it combines with oxygen to form oxides of nitrogen (NOx). This happens in the engine’s combustion chambers when temperatures are too high. NOx itself is not harmful, but when exposed to sunlight it combines with unburned hydrocarbons to create the visible air pollutant known as smog. Smog is a serious problem in California as well as many other heavily populated areas of the United States. Controlling Emissions There are two principle methods of reducing emissions from a two-stroke-cycle marine engine. The first method is to control the air/fuel ratio that goes into the combustion chamber. The second is to control the time when this air/fuel mixture enters the combustion chamber. Timing is important, to prevent any unburned mixture from escaping out of the exhaust port. Page 3C-2 90-857138R1 MAY 2000 EMISSIONS Stoichiometric (14.7:1) Air/Fuel Ratio In the search to control pollutants and reduce exhaust emissions, engineers have discovered that they can be reduced effectively if a gasoline engine operates at an air/fuel ratio of 14.7:1. The technical term for this ideal ratio is stoichiometric. An air/fuel ratio of 14.7:1 provides the best control of all three elements in the exhaust under almost all conditions. The HC and CO content of the exhaust gas is influenced significantly by the air/fuel ratio. At an air/fuel ratio leaner than 14.7:1, HC and CO levels are low, but with a ratio richer than 14.7:1 they rise rapidly. It would seem that controlling HC and CO by themselves might not be such a difficult task; the air/fuel ratio only needs to be kept leaner than 14.7:1. However, there is also NOx to consider. As the air/fuel ratio becomes leaner, combustion temperatures increase. Higher combustion temperatures raise the NOx content of the exhaust. But, enrichening the air/fuel ratio to decrease combustion temperatures and reduce NOx also increases HC and CO, as well as lowering fuel economy. So the solution to controlling NOx - as well as HC and CO - is to keep the air/fuel ratio as close to 14.7:1 as possible.

All other models exclusively use a homogenized charge. The difference between the two is: Homogenized Charge A homogenized charge has the air/fuel particles mixed evenly throughout the cylinder. This mixing occurs inside the carburetor venturi, reed blocks, crankcase and/or combustion chamber. Additional mixing occurs as the fuel is forced through the transfer system into the cylinder. The homogenized charge has an air/fuel ratio of approximately 14.7:1 and is uniform throughout the cylinder. Page 3C-4 90-857138R1 MAY 2000 EMISSIONS Stratified Charge A stratified charge engine only pulls air through the transfer system. The fuel required for combustion is forced into the cylinder through an injector placed in the top of the cylinder (head). The injector sprays an air/fuel mixture in the form of a cloud into the cylinder. Surrounding this cloud is air supplied by the transfer system. As the cloud is ignited and burns, the surrounding air provides almost complete combustion before the exhaust port opens. A stratified charge engine concentrates a rich mixture in the vicinity of the spark plug (air/fuel ratio less than 14.7:1). Elsewhere, the mixture is very lean or is comprised of air only. 90-857138R1 MAY 2000 Page 3C-5 EMISSIONS Emissions Information Manufacturer’s Responsibility Beginning with 1998 model year engines, manufacturers of all marine propulsion engines must determine the exhaust emission levels for each engine horsepower family and certify these engines with the United States Environmental Protection Agency (EPA). A certification decal/emissions control information label, showing emission levels and engine specifications directly related to emissions, must be placed on each engine at the time of manufacture. Dealer Responsibility When performing service on all 1998 and later outboards that carry a certification, attention must be given to any adjustments that are made that affect emission levels. Adjustments must be kept within published factory specifications. Replacement or repair of any emission related component must be executed in a manner that maintains emission levels within the prescribed certification standards. Dealers are not to modify the engine in any manner that would alter the horsepower or allow emission levels to exceed their predetermined factory specifications. Exceptions include manufacturers prescribed changes, such as that for altitude adjustments. Owner Responsibility The owner/operator is required to have engine maintenance performed to maintain emission levels within prescribed certification standards. The owner/operator is not to modify the engine in any manner that would alter the horsepower or allow emissions levels to exceed their predetermined factory specifications. Exceptions: • Carburetor jets may be changed for high altitude use in accordance with factory recommendations. • Single engine exceptions may be allowed with permission from the EPA for racing and testing. Page 3C-6 90-857138R1 MAY 2000 EMISSIONS EPA Emission Regulations All new 1998 and later outboards manufactured by Mercury Marine are certified to the United States Environmental Protection Agency as conforming to the requirements of the regulations for the control of air pollution from new outboard motors. This certification is contingent on certain adjustments being set to factory standards. For this reason, the factory procedure for servicing the product must be strictly followed and, whenever practicable, the product returned to the original intent of the design. The responsibilities listed above are general and in no way a complete listing of the rules and regulations pertaining to the EPA laws on exhaust emissions for marine products.

New gaskets MUST BE installed during reassembly. During reassembly, lubricate parts with Quicksilver 4-Cycle Outboard Oil whenever “light oil” is specified. Quicksilver part numbers of lubricants, sealers and locking compounds are listed under “Quicksilver Lubricants and Service Aids,” preceding. A torque wrench is required for correct reassembly of powerhead. DO NOT attempt to reassemble powerhead without using a torque wrench. Attaching bolts for covers and housings MUST BE torqued by tightening bolts in 3 progressive steps (following specified torque sequence) until specified torque is reached. Powerhead torques are listed under “Torque Specifications,” preceding. 1.
