STEERING LINK ROD FASTENERS

IMPORTANT: The steering link rod that connects the steering cable to the
engine must be fastened using special washer head bolt ("a" – Part Number
10-14000) and self locking nylon insert locknuts ("b" & "c" – Part Number
11-34863). These locknuts must never be replaced with common nuts (non
locking) as they will work loose and vibrate off freeing the link rod to
disengage.
WARNING
Disengagement of a steering link rod can result in the boat taking a full,
sudden, sharp turn. This potentially violent action can cause occupants
to be thrown overboard exposing them to serious injury or death.
Assemble steering link rod to steering cable with two flat washers (d) and self
locking nylon insert locknut ("b" – Part Number 11-34863). Tighten locknut (b) until
it seats, then back nut off 1/4 turn.
Assemble steering link rod to engine with special washer head bolt ("a" – Part
Number 10-14000) and self locking nylon insert locknut ("c" – Part Number
11-34863). First torque bolt (a) to 20 lb. ft. (27.1 N·m), then torque locknut (c) to
20 lb. ft. (27.1 N·m).

CORROSION CONTROL ANODE

Your outboard has control anodes at different locations. An anode helps protect
the outboard against galvanic corrosion by sacrificing its metal to be slowly eroded
instead of the outboard metals.
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.
1
The gear case has two corrosion control anodes (a). Another anode (b) is
installed on the bottom of the transom bracket assembly. An anode helps
protect the outboard against galvanic corrosion by sacrificing its metal to be
slowly eroded instead of the outboard metals.
Note: Do not remove center bolt (f) until cover had been removed from engine.
2
Three anodes (d) are installed in the engine. Remove anodes at locations
shown. Install each anode with rubber seal (e) and cover (c). Tighten bolts to
70 lb. in. (8 Nm) torque.

PROPELLER REPLACEMENT

If the propeller shaft is rotated while the engine is in gear, there is the pos-
sibility that the engine will crank over and start. To prevent this type of
accidental engine starting and possible serious injury caused from being
struck by a rotating propeller, always shift outboard to neutral position
and remove spark plug leads when you are servicing the propeller.
1
Shift outboard to neutral (N) position.
IMPORTANT: Refer to Spark Plug Inspection and Replacement Section for
correct procedure for removing spark plug leads.

3
Straighten the bent tabs on the propeller nut retainer.
4
Place a block of wood between gear case and propeller to hold propeller and
remove propeller nut.
5
Pull propeller straight off shaft. If propeller is seized to the shaft and cannot be
removed, have the propeller removed by an authorized dealer.
