(4) Running-inoperation @Procedure l) It is important to note that the service life of an outboard motor depends largely on how it is operatedduring its initial period. Operation under heavily loaded conditions causesabnormalwear on sliding components before proper contact is achieved.This impairs engine performancefor the rest of its life. The purpose of running-in the engine is to provide proper contact between sliding parts by avoidingundue loading during its initial operation period. This will assurehigh engine perforrnancefor an extendedperiodof time.

2) The engineshould be run for at leastten hours, usingthe following procedure: a) For the first 30 minutes, operate the motor at 1/4 throttle. After this period, gradually open the throttle to the ll2 position, and continue motor operation for 2.5 hours.

During this three-hour running-in period, use fuel with a 20:1 gasoline-oil ratio. b) During the subsequent two hours, continue to run-in the engineby gradually opening the throttle from ll2 to 3/4 position. Every 30 minutes during this period, fully open the throttle once for about 30 seconds(be sure not to 24

exceed the allowable maximum ensine rpm).

During this two-hour period, use the 20: I fuel mixture ratio. c) After completing the first five hour period, change the fuel mixture to a 50: I ratio, and conduct another fivehour running-in operation at 3/4 throttle. Every 30 minutesduring this period, fully open the throttle once for about one minute (be sure not to exceedthe allowablemaximum enginerpm).

@ Inspectionafter running-in The running-in operation is designcdto achieveproper contactbetweenrotatingor sliding parts. This may result in some looseningof parts or productionof rnetal shavingsdue to lapping action on the sliding surfaces.The outboard motor must be checked for these conditions after the running-in operation,and reconditionedas necessary to assure high performance during the service life. The inspection procedureis described below: 1) Check bolts and nuts for looseness.

Check the fuel strainer for contamination or clogging,and the strainercup for water. Refer to the section "Daily inspection"for detailedprocbdures.

3) Checkconditionof sparkplug.

Remove the spark plug and check for contamination and spark condition. See "Daily inspection".

@ ltter operationin salt water or muddy water First, flush the cooling system with fresh water to prevent corrosion. Use the follow' ing procedure: l) Removethe propeller and fill a tank or tab with freshwater. Immersethe lower portion of the motor in water. Run the engine at low speed for l0 to l5 minutes to remove salt and other contamination from the cooling system.

Continue to supply fresh water to the tank while the engineis running.

After startingthe engine,water will no longer be dischargedfrom the contact section;instead,it will be suckedinto the engine.

4) Washthe outsideof the outboard motor with water, and wipe the entire surface with nonflammablesolvent.Apply paint to scratchesor peeled sections,if any.

Apply rust preventive to the entire surface, and lubricate the sliding portions.

@ Mooring If the boat is moored with the outboard motor in the water, metal parts may corrode, or the propeller and lower casemay be damagedby striking bottom. To avoid theseproblems, tilt the motor up as far as possible.

26

In winter, when the air temperaturedrops below OoC(32"F), removethe lock plate from the safety switch and rotate the starter motor for severalsecondswith the motor tilted up. This will thoroughly drain the cooling water from the engine.

@ Wtrenthe motor is immergedin water If the outboard motor is dropped into and serviced water, it must be disassembled quickly. Delayed servicingmay lead to rust formation insidethe engine.Operationof a rusted motor will result in a damagedor disabledengine.Contact the nearestNissan Marine dealerimmediatelyand ask them to disassembleand service the motor, after conducting the following temporary procedure: l) Remove the motor from the water as quickly as possible,and washthoroughly with fresh water.

2) Removethe spark plugs. Attach the accessory starter rope to the flywheel starter pulley. Pull the rope to crank the engine for draining water from the engine cylinder through the spark plug holes.

3) After draining water from the engine, pour a sufficient amount of engineoil into the spark plug holes and into the carburetor. Attach the starter rope to the starter pulley and crank the engine so that the oil will coat the entire engine.

4) After completing the above procedure, take the motor to a Nissan Marine dealerand haveit serviced.
