4. Place rear thrust hub on propeller shaft.
5. Place locking tab washer on propeller shaft, then
thread propeller nut on shaft.
6. Place propeller nut into recess in locking tab
washer and torque propeller nut to 55 lb. ft. (74.5
N·m). Verify nut is recessed into tab washer while
applying torque.
7. Bend 3 tabs from locking tab washer down into
grooves of propeller hub to secure propeller nut.
8. After first use, bend three tabs straight and retor-
que propeller nut [55 lb. ft. (74.5 N·m)]. Bend tabs
down into propeller hub grooves (check periodi-
cally for tightness.)
CAUTION
If propeller moves fore-and-aft on the propeller
shaft, retighten the propeller nut. Operation with
a loose propeller could cause damage to the
thrust hub and gear housing during acceleration,
deceleration or when shifting gears.

Corrosion Control Anode
The gear case has two corrosion control anodes.
Another anode is installed on the bottom of the tran-
som bracket assembly. An anode helps protect the
outboard against galvanic corrosion by sacrificing its
metal to be slowly eroded instead of the outboard
metals.

a - Gear Case Anodes (2)
b - Transom Bracket Anode
Each anode requires periodic inspection especially
in salt water which will accelerate the erosion. To
maintain this corrosion protection, always replace
the anode before it is completely eroded. Never paint
or apply a protective coating on the anode as this will
reduce effectiveness of the anode.
