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
after every 10 hours of operation. After every 30
hours of operation, pump in extra grease to purge out
any moisture.

c - Grease Exiting Vent Hose
Lubricating Procedure - Pull vent hose (a) off the
grease fitting. Pump in grease (b) through the grease
fitting (using the grease gun provided) until excess
grease starts to exit the vent hose (c).
Reconnect the vent hose (a) onto the grease fitting
after 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 conditions inside the bearing housing. A gradual
increase in moisture content, indicates seal wear. If
the grease begins to turn dark, dirty gray, the drive
shaft bearing and seals should be inspected and re-
placed 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 key-
way is directly above the flat on the shaft. This will
free the jammed key and allow removal.
