WARNING

•Before performing any maintenance on the engine disconnect the spark plug wire from the spark plug to prevent unintentional sparking.

•Unintentional sparking can result in fire or electric shock.

•Unintentional start#up can result in entangle# ment, traumatic amputation or laceration.

•Use only correct tools.•Do not tamper with engine speed.

Follow the hourly or calendar intervals, whichever occur first. More frequent service is required when operating in adverse conditions noted.

First 5 - 8 hoursDChange oil.* Every 8 hours or dailyDCheck oil level.DCheck fuel system.DCheck linkages and throttle for freedom of move# ment.

DCheck outboard installation, and operation of pro# peller, steering handle, and starter.

Every 25 hours or every seasonDChange oil.*DCheck gear case oil of lower unit.Every 50 hours or every seasonDChange gear case oil of lower unit.DReplace spark plug.**DReplace fuel filter.Every 100 hours or every seasonDCheck valve clearance.DClean combustion chamber deposits.

* Change oil more frequently when operating the engine under heavy load or in high temperatures.

**In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this engine was originally equipped with resistor spark plug, use same type of spark plug for replacement.

CHANGING ENGINE OIL

 

WARNING

•DO NOT grab the muffler or muffler guard when removing the outboard from the boat.

CAUTION: Outboard MUST be in the vertical position when checking and changing the oil.

1.With engine OFF but still warm, remove the oil drain plug Ê. Drain the old oil from the engine into an approved container.

2.After all the oil has drained out of the engine, install the oil drain plug. Tighten the plug.

3.Remove the dip stick/oil filler cap.4.Refill engine with approx. 24 oz. of oil Ë. DO NOT overfill.

5.Check the oil level. Insert the dipstick into the oil fill tube and screw in. Remove dipstick and check oil level on the dipstick. Oil should be at the FULL mark Ì. Add oil if necessary.

Fig. 9

CHANGING GEAR CASE OIL

 

1.Place the outboard in vertical position.2.Remove vent plug Êand gear oil drain/fill plug Ë.3.Drain the gear oil. Allow the oil to drain for a minimum of 15 minutes.

4.Insert the nozzle of the new gear oil bottle Ì into the oil fill hole. Fill gear case with gear oil.

CAUTION: It is necessary to purge ALL the air from the gear case when replacing or adding gear oil. Slowly squeeze the bottle until a steady stream of gear oil runs

from the vent hole Í.

5.Install the vent plug while continuing to supply oil to the gear case. Install gear oil fill plug.

Note: If the gear case oil appears milky, indicating wa# ter in the oil; or if the oil has indications of high wear, such as steel particles in the oil, contact an Authorized Briggs & Stratton Dealer.

FUEL SYSTEM

WARNING

•Replacement parts for fuel system (tank, hoses, valves, etc.) must be the same quality as original parts, otherwise fire can occur.

Replacing Fuel Filter

Remove the engine cover. Replace fuel filter. Check filter for water or debris. If found, clean fuel system. Reinstall the engine cover.

SPARK PLUG

•The electrodes on the spark plug must be clean and sharp to produce the powerful spark required for ignition. If the spark plug is worn or dirty the engine will be hard to start.

•Ensure spark plug gap is 0.51 mm or 0.020 in.VALVE CLEARANCE

Measure valve clearance with valve springs installed and piston 6 mm (0.25 in.) past top dead center. Check when engine is cold. See Briggs & Stratton repair manual, Part No. 275110.

COMBUSTION DEPOSITS

After 100 hours of operation the combustion deposits should be removed from the cylinder, cylinder head, top of piston and around valves.

CLEANING OUTBOARD

Engine and parts should be kept clean to maintain freedom of movement, and to reduce the risk of overheating from accumulated debris.

CAUTION: DO NOT use water to clean engine parts. Water could contaminate fuel system. Use a brush or dry cloth.

ADJUSTMENTS

Fig. 10 THROTTLE ADJUSTMENT

1.With engine off, and throttle control in the IDLE position, loosen casing clamp screw Êat the back of the engine.

2.Push the throttle cable in direction of arrow toward the control bracket. moving the throttle bracket Ë firmly against the idle speed screw.

3.Secure the casing clamp screw. Rotate throttle control hand grip observing motion in the bracket while turning from IDLE to HIGH Speed. There should be freedom in motion.

Fig. 11 CARBURETOR ADJUSTMENT

WARNING

•Outboard must be in NEUTRAL to adjust idle.•Keep hands and feet from rotating parts.

WARNING

•The outboard uses a factory installed electronic engine speed limiter to control engine speed. Do not attempt to alter the electronic engine speed limiter or change the top speed setting.

1.Using a tachometer (B&S P/N 19389) adjust the idle RPM with the outboard in NEUTRAL.

2.Rotate throttle control counter#clockwise and hold so throttle bracket is firmly against idle speed screw. While holding, adjust speed screw to obtain 1900 RPM#No Load (1400 RPM Full Load).

3.Rotate the throttle control to HIGH speed. Engine should accelerate smoothly. If not see an Authorized Briggs & Stratton Service Dealer.

Note: For high altitude operation, above 900 meters or 3000 feet, consult your Authorized Briggs & Stratton Dealer.

TRANSPORTING

Fig. 12 TRAILERING THE OUTBOARD CAUTION

Before transporting, ensure the outboard is secure. DO NOT transport with the outboard tilted up! Trailering the outboard unsecured or in a tilted position will damage the boat and/or outboard. If attached to the transom, secure to prevent bounce, tilt or the possibility of falling off.

•When transporting outboard, while still attached to boat, secure it in the vertical position. If not possible remove the outboard and secure it in the proper horizontal position.

•Use a trailer with adequate clearance Ë to prevent damage to the outboard Ê from curbs, pavement or other objects.

•It is the OWNER/OPERATOR'S responsibility to secure the outboard. If attached to the transom when transporting, secure to prevent bounce, tilt or the possibility of falling off.
