OPERATION 3
TIP: Pre-operation checks should be
made each time the boat is used.
These checks can be completed in a
short time. It is worth the time spent to
ensure safety and reliability.
CHECK POINTS
Steering
Make sure the wheel is not loose.
There should not be any free play,
either in-and-out or in rotation. Turn
the steering wheel full-right and full-
left to make sure operation is smooth
and unrestricted throughout the whole
range.
Make sure both jet nozzles change
directions as the steering wheel is
turned. The jet nozzles should point
to starboard (right) when the wheel is
turned right. The jet nozzles should
point to port (left) when the wheel is
turned left. There should not be free
play between the steering wheel and
the jet nozzles.
Throttle/Shifters
Move the control levers several times
through their full range of motion.
Operation should be smooth over the
complete range of motion and the
levers should return to Neutral without
hesitation.
Before launching, make sure both jet
pump gates drop down over the jet
nozzles to their stopper positions when
the control levers are moved to the
Reverse position. Also be sure both jet
pump gates return to the full-up stopper
position when the levers are moved to
the Forward position.
