Product Information
Propeller
Propeller Selection
To select the correct propeller for your boating
application, your boat and outboard MUST be
water tested. See your Dealer for assistance.
IMPORTANT: The correct propeller for your
boat, under normal load conditions, will allow
the engine to run near the midpoint of the
RPM operating range at full throttle. Refer to
Specifications on page 77.
Installation
Slide thrust washer onto shaft with shoulder
facing aft.
Slide propeller onto shaft, engaging the
splines and seating it on the thrust bushing.
Slide spacer onto the shaft and engage the
propeller shaft splines.
Wedge a block of wood between the propeller
blade and the anti-ventilation plate.
20 Inch Models — Install propeller nut and
tighten to a torque of 120-144 in. lbs. (13.6-
16.3 N·m).
25 Inch Models — Install propeller nut and
tighten to a torque of 70 to 80 ft. lbs. (95 to
109 N·m). Install keeper on propeller nut,
align keeper slots and cotter pin hole.
IMPORTANT: If cotter pin holes in the propel-
ler nut and propeller shaft are not aligned,
tighten the nut until they are in line. Do not
loosen.
Install new cotter pin and bend ends to se-
cure.
Remove block of wood. Make sure engine is
in NEUTRAL; give propeller a spin. It must
turn freely.
Repair
If your propeller hits a solid object, the impact
is partially absorbed by the bushing in the hub
to help prevent damage to the outboard. A
strong impact can damage the hub and pro-
peller blades. Damage to blades can cause
unusual and excessive vibration. Damage to
the hub can cause excessive engine RPM
with little forward movement.
Keep your propeller in good condition. Use a
file to smooth slight damage to blade edges.
See your Dealer for repair of serious damage.
WARNING
When servicing the propeller, always
shift the outboard to NEUTRAL position,
turn the key switch OFF, and twist and
remove all spark plug wires so the out-
board cannot be started accidentally.
NOTICE
Apply Triple-Guard grease to the entire
propeller shaft before installing the pro-
peller. At least annually, remove the pro-
peller and check for debris. Clean the
shaft and re-grease it before reinstalling
a propeller.

NOTICE
Avoid or limit operation using a dam-
aged propeller. Carry a spare propeller.
