must be disposed of in an approved receptacle. Any fuel system service must be
performed in a well ventilated area. Inspect any completed service work for sign
of fuel leakage.

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
10-849838) 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.
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 10-849838) 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).

in the wiring. If a fuse is blown, try to locate and correct the cause of the overload.
If the cause is not found, the fuse may blow again.
1
Open the fuse holder and look at the silver colored band inside the fuse. If band
is broken, replace the fuse. Replace fuse with a new fuse with the same rating.
