Maintenance
4.
Remove the oil level plug and gasket to
allow the 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.
TIP:
For disposal of used oil, consult your Yamaha
dealer.
5.
Put the outboard motor in a vertical posi-
tion. Using a flexible or pressurized filling
device, inject the gear oil into the gear oil
drain screw hole.

WARNING
Be sure the outboard motor is securely
G
fastened to the transom or a stable
stand. You could be severely injured if
the outboard motor falls on you.
Never get under the lower unit while it is
G
tilted, even when the tilt support lever or
knob is locked. Severe injury could oc-
cur if the outboard motor accidentally
falls.
1.
Tilt the outboard motor so that the gear oil
drain screw is at the lowest point possi-
ble.
2.
Place a suitable container under the gear
case.
3.
Remove the cooling water inlet covers on
both sides of the gear case. Be careful
not to lose the bolt and nut.
4.
Remove the gear oil drain screw and gas-
ket. The screw is magnetic so a small
quantity of metal particles on the end of
the screw is normal. Simply remove
them. NOTICE: If there is an excessive
quantity of metal particles on the mag-
netic gear oil drain screw, this can in-
dicate lower unit problem. Consult
your Yamaha dealer.
