with a passenger and requires greater
skill. The passenger should always
grip the seat strap or grab handle.
Reduce speed and avoid sharp turns.
Avoid choppy water conditions when
carrying a passenger.

CAUTION:
needs air to operate; consequently
this watercraft can not be totally
watertight. Any maneuvers such
as figure eights etc., that cause
the upper deck to be under water
may cause severe engine problems
due to water ingestion. Refer to
SPECIAL PROCEDURES and LIM-
ITED WARRANTY contained in this

Off-Power Assisted Steering
System (O.P.A.S.)
The Off-Power Assisted Steering
(O.P.A.S.) system uses a dual side
vanes design that assists the wa-
tercraft steering in deceleration, to
redirect watercraft path when steer-
ing is turned after throttle has been
released or engine stopped.
The side vanes on the rear sides of the
hull, turn as the steering is turned to
assist the watercraft turning. At first,
carefully experiment turning with this
system.
TYPICAL
1. Side vanes turn following steering
movement
Models with Sliding Side Vanes
(O.P.A.S. System)
When engine is running at approxi-
mately 75% or more RPM, the side
vanes are automatically raised to up-
per position since they are not re-
quired at that vehicle speed range.
engine
Between 30% and 75% engine RPM,
side vanes are gradually raised from
lower position to upper position.
1. Side vane in upper position
When throttle is released and engine
RPM drops, the side vanes are auto-
matically lowered thus assisting steer-
ing control.
