Propeller Installation
WARNING
When installing or removing the propeller on all
models, because of the motor’s ease in starting,
verify that the remote control is in NEUTRAL
position and that the key switch is “OFF”. Place
a block of wood between the anti-cavitation plate
and propeller to prevent accidental motor
starting and to protect hands from propeller
blades while removing propeller nut.
1. Apply a liberal coat of Anti-Corrosion Grease
(92-78376A6) on propeller shaft splines.
2. Place thrust hub onto propeller shaft.
3. While aligning splines, place propeller onto
propeller shaft.

4. Place propeller nut in tab washer groove.
5. Thread propeller nut onto propeller shaft.
6. After propeller nut is recessed into tab washer,
tighten nut securely [minimum of 55 Ib. ft. (74.5
N·m) torque].
7. Bend 3 of the tabs of tab washer down in grooves
of propeller hub to secure propeller nut. (If tab
washer tabs do not align with slots, continue to
tighten propeller nut to obtain alignment. DO
NOT loosen nut to align tabs.)
CAUTION
DO NOT misinterpret propeller shaft movement
with propeller movement. If propeller and
propeller shaft together move forward-and-aft,
this is normal; however, propeller should not
move forward-and-aft on propeller shaft.
8. After first use, retighten propeller nut and again
secure with tab washer (Steps 6 and 7, above).
Propeller should be checked periodically for
tightness, particularly if stainless steel propellers
are used.
