TURNING THE BOAT

Steering control depends on the com-
bination 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 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 boat will turn more sharply.
B. Less throttle produces low thrust, so
the boat will turn more gradually.
C. Pulling the throttle levers complete-
ly back to idle produces only mini-
mum 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 boat will no longer
respond to steering wheel input until
you apply throttle again or you
reach a trolling speed.
At trolling speed, the 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 boat will go straight
even though the steering wheel is
turned.
YOU NEED THROTTLE TO STEER.
