Filling engine oil

The outboard motor is shipped from the factory without engine oil. If your Yamaha dealer did not fill the engine with engine oil, you must fill the engine before starting it. NOTICE:

Make sure that the engine is filled with engine oil before operating the outboard motor for the first time. Otherwise, the engine could be damaged severely. [ECM02240]

The following sticker, which is affixed to the outboard motor when it is shipped from the factory, should be removed after the engine is filled with engine oil for the first time. For more information on checking the engine oil level, see page 50.

Breaking in engine

Your new engine requires a period of break-in to allow mating surfaces of moving parts to wear in evenly. Correct break-in will help ensure proper performance and longer engine life. NOTICE: Failure to follow the break-in procedure could result in reduced engine life or even severe engine damage. [ECM00801]

EMU41222

Procedure for breaking in engine

Your new engine requires a period of 10 hours break-in so that mating surfaces of moving parts wear in evenly.

Operate the engine in the water under load (in gear with a propeller installed) for 10 hours as follows. When breaking in the engine, avoid extended idling, rough water, and crowded ar- eas.

1.For the 1st hour of operation:

Operate the engine at varying speeds up to 2000 r/min or approximately 1/2 throt- tle.

2.For the 2nd hour of operation:

Increase the engine speed until the boat is on plane (but avoid full-throttle opera- tion), and then back off on the throttle while keeping the boat at a planing speed.

3.For the remaining 8 hours of operation: Operate the engine at any speed. How- ever, avoid operating at full throttle for more than 5 minutes at a time.

4.After the 1st 10 hours of operation:

Operate the engine normally.
