Changing gear oil
WARNING
EWM02531
Make sure that the outboard motor is
mounted securely to the transom or a
stable stand. You could be severely in-
jured if the outboard motor falls on you.
Never get under the lower unit while it
is tilted. Severe injury could occur if the
outboard motor accidentally falls.
Before filling the lower unit with gear oil, the
outboard motor must be placed in a vertical
position. If you are not able to place the out-
board motor in a vertical position, have a
Yamaha dealer change the gear oil.
1. Tilt the outboard motor so that the gear
oil drain screw is at the lowest point pos-
sible.
2. Place a suitable container under the
gear case.
3. Loosen the bolt, and then remove the
cooling water inlet covers on both sides
of the gear case.
4. Remove the gear oil drain screw and
gasket.
5. Remove the oil level plug and gasket to
allow the gear oil to drain completely.
NOTICE:
Check the used gear oil after
it has been drained. If the gear oil is
milky or contains water or a large
amount of metal particles, the gear
case may be damaged. Have a
Yamaha dealer check and repair the
outboard motor.
