WARNING
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.

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.
TIP:
For disposal of used gear oil, consult your
Yamaha dealer.
