Changing Gear Oil - Yamaha F6 Owner's Manual

Be sure to use a new cotter pin and bend
G
the ends over securely. Otherwise the
propeller could come off during opera-
tion and be lost.
1. Apply Yamaha marine grease or a corro-
sion resistant grease to the propeller
shaft.
2. Install the spacer (if equipped), thrust
washer, and propeller on the propeller
shaft.
3. Install the spacer (if equipped) and the
washer. Tighten the propeller nut to the
specified torque.
4. Align the propeller nut with the propeller
shaft hole. Insert a new cotter pin in the
hole and bend the cotter pin ends.
NOTE:
If the propeller nut does not align with the pro-
peller shaft hole after tightening to the speci-
fied torque, tighten the nut further to align it
with the hole.

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.
