Chapter 2 - General Maintenance
(continued)
When a stainless steel propeller is used, care must be taken to maintain good continuity between the prop
and the prop shaft to prevent corrosion. Periodic removal of the propeller, a thorough cleaning of its hub,
the prop shaft and all mounting components, and lubrication of the shaft with
marine grade grease
(or
equivalent) will help maintain good continuity and prevent corrosion. A continuity washer can be installed
between the propeller and the splined washer on all models to help maintain continuity.
Inspection
1. Check Aft propeller shaft nut for correct torque, 60 lb. ft. (81 Nm).
2. Check propeller blades for any indication of damage.
3. After removal of aft propeller, check forward propeller shaft nut for correct torque, 100 lb. ft. (136 Nm).
Removal
1. Once procedure below is completed for the aft propeller, repeat steps to remove the forward propeller.
2. Place a block of wood between the propeller and cavitation plate.
3. Remove aft propeller nut with 1

” socket and breaker bar (for forward propeller, use hex wrench
TO-121).
4. Remove additional propeller hardware (see diagram on previous page).
5. Slide propeller off of splined shaft.
Installation
FORWARD Propeller:
1a. Slide forward thrust hub onto forward prop
shaft so the tapers meet. Some grease can be
used on tapers to hold in place.
2a. Grease splined area and the threads of the
forward propeller shaft.
3a. Place the forward propeller on the propeller
shaft until it seats against thrust hub.
4a. Torque the forward propeller nut to 100 lb.ft.
(136 Nm) using hex wrench TO-121.
AFT Propeller:
1b. Slide aft thrust hub onto aft prop shaft so the
tapers meet. Some grease can be used on tapers
to hold in place.
2b. Grease splined area and the threads of the aft
propeller shaft.
3b. Place the aft propeller on the propeller shaft
until it seats against thrust hub.
4b. Torque the aft propeller nut to 60 lb.ft. (81
Nm) using 1
7
/
16
” socket wrench.
