Operating Instructions; Principle Of Operation - SeaDoo 2002 GTX 4-TEC Operator's Manual

OPERATING INSTRUCTIONS

WARNING
Always perform the PRE-OPERATION
CHECKS before operating the water-
craft. Become thoroughly familiar
with all controls and the function of
each. Should any control or instruc-
tion 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 accurately ad-
justed in a housing where the water is
drawn up from underneath the water-
craft. Then the water flows through
the impeller to a venturi. The venturi
accelerates the water and produces
thrust to move the watercraft. De-
pressing the throttle lever increases
engine speed and therefore watercraft
speed.

WARNING
Keep away from intake grate while
engine is on. Items such as long
hair, loose clothing or personal flo-
tation device straps can become
entangled in moving parts result-
ing in severe injury or drowning.
The shift lever should be in the forward
position in order for the watercraft to ad-
vance.
Neutral and Reverse
WARNING
Never use jet pump components as
a supporting point to board the wa-
tercraft. 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 re-
verse at slow speed and for the
shortest time possible. Always en-
sure the path behind is clear of ob-
jects and persons including chil-
dren 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.
WARNING
When the watercraft is in neutral
position, the drive shaft and impel-
ler are still turning.
