OPERATING INSTRUCTIONS

WARNING
Always perform the PRE-OPER-
ATION CHECKS before operat-
ing the watercraft. Become thor-
oughly familiar with all controls
and the function of each. Should
any control or instruction not be
fully understood, refer to an au-
thorized 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 accurately
adjusted in a housing where the wa-
ter 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
started, the operator and passen-
ger(s) should always be properly
sitting on the watercraft and be
wearing protective clothing in-
cluding a Coast Guard approved
PFD and a wet suit bottom.
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 completely
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
including children playing in shal-
low 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 t he 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 tur ning.
