Yamaha SR230, Owner'S/Operator'S Manual, Page: 50 / 118

NOTE: Pre-operation checks should be
made each time the boat is used. This
procedure can be accomplished thor-
oughly in a short time. The added safe-
ty and reliability the checks assure is
worth the time involved.
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
Operate the throttle levers several
times to make sure there is no hesita-
tion in their travel. Operation should be
smooth over the complete range of
motion, and each lever should return
completely to the idle position.
Shifting
Before launching, make sure both jet
pump gates drop down over the jet
nozzles to their stopper positions when
the shift lever is moved to the
“Reverse” position. Also make sure
both jet pump gates return to the full up
stopper position when the shift lever is
moved to the “Forward” position.
