ANTICORROSION ANODES
Remove  block  of  wood.  Make  sure  engine  is  in
NEUTRAL; give propeller a spin. It must turn freely.
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.

Fish Line Trap
The thrust bushing contains a built-up groove as a
trap for fish line. Every 15 to 20 hours of operation,
or whenever you suspect the presence of fish line,
remove the propeller and check the trap. Remove
any debris.

Anticorrosion 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.
