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.

ket. NOTICE: If there is an excessive

equipped, remove all metal particles from
the screw before installing it.
Always use new gaskets. Do not reuse the
G
removed gaskets.
4.
Remove the oil level plug and gasket to
allow the oil to drain completely.

sult a Yamaha dealer for repair of the
lower unit seals.

For disposal of used oil, consult your Yamaha
dealer.

tion. Using a flexible or pressurized filling
