OPERATING INSTRUCTIONS

WARNING
Always perform PRE-OPERATION
CHECKS before operating the boat.
Become thoroughly familiar with
all controls and the function of
each. Should any control or instruc-
tion 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.

Trailering

Refer to the trailer instructions for
proper capacity, operation, mainte-
nance, accessories and warranty.
Check the regulations in your area con-
cerning towing a trailer, especially the
following rules:
– brake system
– tow vehicle weight
– mirrors.
NOTE: An optional brake system is
available for your trailer, contact Karavan
Trailers (www.karavantrailers.com).
Take the following precautions when
trailering the boat:
Tie the boat to both bow and stern
(front/rear) eyelets so that it is firmly
retained on the trailer.
– Remove stern light (if installed).
– Ensure all storage compartment cov-
ers are properly latched.
– A Sea-Doo cover can protect the
boat, particularly before driving on
dirt roads, to prevent dirt entry
through the air intake openings.
Observe trailering safety precautions.
CAUTION: Always ensure rear stor-
age compartment lid is closed and
securely fastened before trailering.

Principle of Operation

Propulsion
The 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 for-
ward increases engine speed and
therefore boat speed.
When the shift lever is pushed for-
ward, the boat moves forward. Pulled
back in the reverse position, the boat
moves backwards. The middle position
is neutral and the boat is at the mini-
mum thrust for most conditions. Neu-
tral and reverse are achieved by means
of a gate, which is installed on the jet
pump venturi housing. This gate di-
rects the water flow to obtain the de-
sired direction.
