Avoid draining the engine oil immediately after stopping the engine. The oil is hot and should be handled with care to avoid burns.

NOTICE

Change the engine oil after the first 20 hours of operation or 3 months, and every 100 hours or at 1-year intervals thereafter. Otherwise the engine will wear quickly.

To prevent spilling oil where it could cause damage to nature, it is strongly recommended that you use an oil changer to change the engine oil. If an oil changer is not available, drain the engine oil by removing the drain screw. If you are not familiar with the procedure for changing the engine oil, consult your

Yamaha dealer.

1. Put the outboard motor in an upright position (not tilted). NOTICE: If the outboard motor is not level, the oil level indicated on the oil dipstick may not be accurate.

TIP:

If a torque wrench is not available when you are installing the drain screw, finger tighten the screw just until the gasket comes into contact with the surface of the drain hole.

Then tighten 1/4 to 1/2 turn more. Tighten the drain screw to the correct torque with a torque wrench as soon as possible.

8. Add the correct amount of oil through the filler hole. Put back the filler cap and the
