PERATION
TURNING THE SPORT BOAT
Steering control depends on the combi-
nation of steering wheel position and
the amount of throttle.
Water sucked in through the intake
grate is pressurized by the impeller in
the jet pump. As the pressurized water
is expelled from the pump through the
jet thrust nozzle, it creates thrust to
move and steer the Sport Boat. The
higher the engine speed, the more
thrust is produced.
The amount of jet thrust, in addition to
the position of the steering wheel,
determines how sharply you turn.
A. More throttle produces high thrust,
so the Sport Boat will turn more
sharply.
B. Less throttle produces low thrust, so
the Sport Boat will turn more gradu-
ally.
C. Pulling the throttle levers completely
back to idle produces only minimum
thrust. If you are traveling at speeds
above trolling, you will have rapidly
decreasing ability to steer without
throttle. You may still have some
turning ability immediately after
pulling the throttle levers back to
idle, but once the engine slows
down, the Sport Boat will no longer
respond to steering wheel input until
you apply throttle again or you reach
a trolling speed.
At trolling speed, the Sport Boat can
be turned gradually by steering
wheel position alone using just the
amount of thrust available at engine
idle.
D. If the engines are stopped, there is
no thrust. The Sport Boat will go
straight even though the steering
wheel is turned.
YOU NEED THROTTLE TO STEER.
