Propeller Replacement
SERVICING YOUR OUTBOARD MOTOR
Removal
Installation
Do not tighten the castle nut above
the TIGHTENING TORQUE LIMIT,
or the propeller and shaf t may be
damaged.
TIGHTENING TORQUE LIMIT: Before replacing the propeller,
remove the emergency stop switch
clip from the emergency stop switch
to prevent any possibility of the
engine being started while you are
working with the propeller.
The propeller blades may have sharp
edges, so wear heavy gloves to
protect your hands.
Operating the outboard motor at
higher altitudes will reduce available
power. This may require decreasing
the propeller pitch to maintain correct
engine RPM.
Remove the cotter pin, unscrew
the castle nut, remove the washer,
and then remove the propeller and
thrust washer.
Inspect the propeller shaft for any
fishing line or debris.
Apply marine grade grease to the
propeller shaft.
Install the thrust washer with the
grooved side toward the gear case.
Install the propeller, the special
spline washer and the plain washer.
Lightly tighten the castle nut by
hand or wrench until the propeller
has no free play.
Tighten the castle nut using torque
wrench.
Then, using a torque wrench,
tighten the castle nut until the first
available groove in the castle nut
aligns with the cotter pin hole. Do
not tighten past the first alignment
of the castle nut groove and the
cotter pin hole.
