TIP:
If a magnetic gear oil drain screw is
equipped, remove all metal particles from
the screw before installing it.
Always use new gaskets. Do not reuse the
removed gaskets.
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.

Inspecting and replacing anode(s)
Yamaha outboard motors are protected from
corrosion by sacrificial anodes. Inspect the
external anodes periodically. Remove scales
from the surfaces of the anodes. Consult a
Yamaha dealer for replacement of external
anodes.
