CHANGING GEAR OIL
w
8 Be sure the outboard motor is securely
fastened to the transom or a stable
stand. You could be severely injured if
the outboard motor falls on you.
8 Never get under the lower unit while it
is tilted, even when the tilt support
lever or knob is locked. Severe injury
could occur if the outboard motor
accidentally falls.
1) Tilt the outboard motor so that the gear
oil drain screw is at the lowest point
possible.
2) Place a suitable container under the
gear case.
3) Remove the gear oil drain screw 1.
4) Remove the oil level plug 2 to allow
the oil to drain completely.
cC
Inspect the used oil after it has been
drained. If the oil is milky, water is get-
ting into the gear case which can cause
gear damage. Consult a Yamaha dealer
for repair of the lower unit seals.
NOTE:
For disposal of used oil consult your
Yamaha dealer.
