OPERATING INSTRUCTIONS ____________________
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 water-
craft speed.
TYPICAL
Reverse
(GTS/GTI/GTX Models)
The selector lever is used for either
driving the watercraft forward or back-
ward. With the lever pushed in, the
watercraft is in forward position, with
the lever fully pulled out, reverse posi-
tion is obtained. The lever middle posi-
tion is neutral. These 3 functions are
produced by the mean of a gate,
which is installed on jet pump venturi
housing. This gate directs the water
flow to get the proper function.
Variable Trim System (VTS)
(SPX/GSI/GSX/XP Models)
The variable trim system (VTS) chang-
es the angle of the jet pump nozzle to
provide the operator with a fast, effec-
tive system to compensate for load,
thrust, riding position and water condi-
tions. Correctly adjusted, it can im-
prove handling, reduce porpoising,
and position the watercraft at its best
riding angle to attain maximum perfor-
mance.
When first using the craft, the opera-
tor should become familiar with the
use of the variable trim system (VTS)
at varying speeds and water condi-
tions. A mid-range trim is generally
used when cruising. Experience alone
will dictate the best trim for the condi-
tions. During the watercraft break-in
period, when lower speeds are rec-
ommended, it is an excellent opportu-
nity to gain familiarity of trim adjust-
ment and its effects.
◆
WARNING
Always perform the PRE-OPERA-
TION CHECKS before operating
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 dealer.
◆
WARNING
Whenever the engine is to be
started, the operator and any
passenger(s) should always be
sitting on the watercraft.

WARNING

used when the engine is idling.
Ensure lever is pushed in and
locked.
