OPERATING INSTRUCTIONS

WARNING
Always perform PRE-OPERATION
CHECKS before
boat. Become thoroughly familiar
with all controls and the function
of each. Should any control or in-
struction be not fully understood,
refer to an authorized Sea-Doo
Sport Boat dealer.

Launching/Loading

CAUTION: Before launching the
boat, ensure the main battery
cut-off switch is turned ON and
the bilge plugs are fully screwed
into place.
When finished loading the boat on
trailer, turn the main battery cut-off
switch to OFF.
Remove bilge plugs to drain bilge
when boat is on trailer.

Principle of Operation

Propulsion
Each engine is directly coupled to a
drive shaft which, in turn, rotates an
impeller. This impeller rotates within
a housing drawing water in from be-
neath the boat. Water is then forced
by the impeller through a venturi. The
venturi pressurizes and accelerates
the water, producing thrust to move
the boat. Pushing the throttle lever
forward increases engine speed and
therefore boat speed.
When shifter lever is pushed for-
ward, the boat moves forward. Pulled
back in the reverse position, the boat
moves backwards. The middle posi-
tion is neutral and the boat is at the
minimum thrust for most conditions.
Neutral and reverse are achieved by
means of gates, which are installed on
the jet pump venturi housings. These
gates direct the water flow to obtain
the desired direction.

NEUTRAL
To obtain neutral, pull shifter lever to
the upright position. Reverse gates
will be in the middle position, direct-
ing half of the thrust toward the front
of the boat to minimize movement.

position, the impellers are turning.
