Continue to tighten propeller nut until nut slots and
cotter pin hole are aligned. Install new cotter pin
and bend ends to secure.
ANTICORROSION ANODES
Your motor is equipped with one or more anodes
that protect it from galvanic corrosion. Refer to Fea-
tures for anode location. Disintegration of the an-
ode is normal and indicates it is working. Check
each anode periodically. Replace anodes smaller
than 2/3 their original size. See your DEALER for
replacements.

Repair
If your propeller hits a solid object, the impact is par-
tially absorbed by the rubber bushing in the hub to
help prevent damage to the engine. A strong impact
can damage the hub and propeller blades. Damage
to blades can cause unusual and excessive vibra-
tion. Damage to the hub can cause excessive en-
gine RPM with little forward movement.

IMPORTANT: Avoid or limit operation using a dam-
aged propeller. Carry a spare propeller.
Keep your propeller in good condition. Use a file to
smooth slight damage to blade edges. See your
DEALER for repair of serious damage.

Anode
Galvanic corrosion destroys underwater metal
parts and can occur in fresh or salt water; however,
salt, brackish and polluted waters will accelerate
corrosion.
Metal-based antifouling paint on the boat or motor
and the use of improperly installed shore power in
the area of your moored boat will also accelerate
corrosion.
IMPORTANT: NEVER paint the anode, its fasten-
ers, or its mounting surface. Painting will reduce its
corrosion protection.
