IMPORTANT: The steering link rod that connects the steering cable to the engine
must be fastened using special bolt (“a” - Part Number 10-90041) and self locking
nuts (“b” & “e” - 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 over-
board exposing them to serious injury or death.
