NOTICE

ECM01710

Change the engine oil after the first 20

hours of operation or 3 months, and ev-

ery 100 hours or at 1-year intervals there-

after. Otherwise the engine will wear

quickly.

To prevent spilling oil where it could cause

damage to nature, it is strongly recommend-

ed 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 proce-

dure for changing the engine oil, consult your

Yamaha dealer.

1. Put the outboard motor in an upright po-

sition (not tilted). NOTICE: If the out-

board motor is not level, the oil level

indicated on the oil dipstick may not

be accurate.

[ECM01861]

2. Start the engine. Warm it up and keep

the idle speed for 5-10 minutes.

3. Stop the engine and leave it for 5-10

minutes.

4. Remove the top cowling.

5. Remove the oil filler cap. Pull out the dip-

stick and use the oil changer to extract

the oil completely.

TIP:

When using an oil changer, skip steps 6 and

7.

6. Prepare a suitable container that holds a

larger amount than the engine oil capac-

ity. Remove the drain screw and gasket

while holding the container under the

drain hole. Let the oil drain completely.

Wipe up any spilled oil immediately.

TIP:

If the oil does not drain easily, change the tilt

angle or turn the outboard motor to port and

starboard to drain the oil.

7. Put a new gasket on the oil drain screw.

Apply a light coat of oil to the gasket and

install the drain screw.
