Lubrication
1) Remove the spark plugs, and spray a
10 second spray of “Yamaha Stor-
Rite Engine Fogging Oil” into each
cylinder. Grease the spark plug
threads and reinstall the spark plugs
and torque to proper specification.
(Refer to “CLEANING AND ADJUST-
ING SPARK PLUG”.)
2) Turn the engine over with the stop
lanyard disconnected to work the fog-
ging oil into the piston rings.
3) Fill the oil tanks. This prevents the for-
mation of condensation. For models
with a remote tank, it may be neces-
sary to manually override the control
unit to completely fill the engine main
tank. (Refer to Oil level warning sec-
tion).
4) Change the lower unit oil. (Refer to
“CHANGING GEAR OIL”). Inspect the
oil for the presence of water which
indicates a leaky seal. Seal replace-
ment should be performed by an
authorized Yamaha dealership prior
to use.
5) Grease all grease fittings. (Refer to
“GREASING”)
