Lubricating The Drive Shaft
Bearing
Recommended Lubrication - Use 2-4-C w/Teflon.
IMPORTANT: It is important that you do not use a
general-all-purpose grease for this bearing. The
lubricant we recommend is a water resistant
grease of the proper consistency for this applica-
tion. If you use a substitute grease, be sure that it
is water resistant and of the same consistency.
Frequency of lubrication - We recommend lubricat-
ing the drive shaft bearing after each day’s use and af-
ter every 10 hours of operation. After every 30 hours
of operation, pump in extra grease to purge out any
moisture.

Lubricating Procedure - Pull vent hose (a) off the
grease fitting. Pump in grease through the grease fit-
ting (using the grease gun (b) provided) until excess
grease starts to exit the vent hose (c).
Reconnect the vent hose (a) onto the grease fitting af-
ter greasing.
After 30 hours of operation, pump in extra grease to
purge out any moisture. Visually inspecting the purged
grease at this time will give you an indication of condi-
tions inside the bearing housing. A gradual increase in
moisture content, indicates seal wear. If the grease be-
gins to turn dark, dirty gray, the drive shaft bearing and
seals should be inspected and replaced if necessary.
Some discoloration of the grease is normal during the
break-in period on a new set of seals.
Impeller Removal and
Installation
REMOVAL
1. Shift outboard to NEUTRAL (N) position.
2. Remove spark plug leads to prevent engine from
starting.
3. Remove the water intake housing that is fastened
with six screws.
4. Straighten the bent tabs (a) on the impeller nut re-
tainer and remove the impeller nut (b).
5. Pull impeller straight off the shaft. If the impeller is
tight, use a hammer and block of wood to rotate the
impeller (clockwise) on the shaft until the keyway
is directly above the flat on the shaft. This will free
the jammed key and allow removal.
