●
Be sure the outboard motor is securely
fastened to the transom or a stable
stand. You could be severely injured if

●
Never get under the lower unit while it is
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.

Place a suitable container under the gear
case.

Remove the gear oil drain screw.

If the magnetic gear oil drain screw equipped:

fore installing it.
4.
Remove the oil level plug to allow the oil
to drain completely.
CAUTION:

Inspect the used oil after it has been
drained. If the oil is milky, water is getting
into the gear case which can cause gear
damage. Consult a Yamaha dealer for re-
pair of the lower unit seals.
NOTE:
For disposal of used oil consult your Yamaha
dealer.
