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 propeller shaft nut for correct torque, 80 lb. ft. (108 Nm).
2. Check propeller blades for any indication of damage.
3. Check tab washer - verify at least two (2) tabs are bent over.
Removal
1. Unbend retaining washer tabs using Konrad Tool TO-063.
2. Place a block of wood between the propeller and cavitation plate.
3. Remove propeller nut.
4. Remove additional propeller hardware (see diagram on previous page).
5. Slide propeller off of splined shaft.
6. Remove thrust washer.
Installation
1. Grease and slide thrust washer onto propeller shaft.
NOTE
: Tapered end of thrust washer must be towards the drive.
2. Grease splined area and the threads of the propeller shaft.
3. Place the propeller on the propeller shaft followed by the appropriate hardware.
(see diagram previous page).
4. Torque the propeller nut, using a 1 7/16” socket tool, to 80 lb. ft. (108 Nm). When approaching 80 lb.
ft. (108 Nm), make sure that the tabs on the tabbed retaining washer (at least 2 out of 6) line up with the
grooves in the splined washer/hub.
NOTE:
A block of wood can be placed between the propeller and the lower drive housing to prevent the
propeller from spinning, while torquing the propeller nut.
5. Bend over the tabs using appropriate tools.
