operating the watercraft. Become
thoroughly familiar with all con-
trols and the function of each.
Should any control or instruction
not be fully understood, refer to
an authorized Sea-Doo dealer.

Principle of Operation

Propulsion
The engine is directly coupled to a
drive shaft which, in turn, rotates an
impeller. This impeller is accurate-
ly adjusted in a housing where the
water is drawn up from underneath
the watercraft. Then the water flows
through the impeller to a venturi. The
venturi accelerates the water and
produces thrust to move the water-
craft. Depressing the throttle lever
increases engine speed and therefore
watercraft speed.
TYPICAL
WARNING
Whenever the engine is to be start-
ed, the operator and passenger(s)
should always be properly sitting
on the watercraft and be wear-
ing protective clothing including a
Coast Guard approved PFD and a
wet suit bottom.

CHECKS
Keep away from intake grate while
engine is on. Items such as long
hair, loose clothing or personal
flotation device straps can become
entangled in moving parts result-
ing in severe injury or drowning.
The shift lever should be in the for-
ward position in order for the water-
craft to advance.
Neutral and Reverse
Never use jet pump components
as a supporting point to board
the watercraft. Shift lever should
only be used when the engine is
idling and watercraft is complete-
ly stopped. Never rev the engine
at high RPM in reverse. Do not
use reverse to stop the watercraft.
Only use reverse at slow speed
and for the shortest time possible.
Always ensure the path behind
is clear of objects and persons in-
cluding children playing in shallow
water.
To find the neutral, set in reverse then
push back until the watercraft stops
moving backwards.
The reverse gate will be in the middle
position, directing half of the thrust to-
ward the front of the watercraft to min-
imize watercraft movement.
When the watercraft is in neutral
position, the drive shaft and im-
peller are still turning.
