Fuel cock knob
The fuel cock supplies fuel from the fuel
tank to the carburetors.
The fuel cock knob 1 positions are
explained as follows and are shown in the
illustration.
OFF:
With the fuel cock knob in this position,
fuel does not flow. Always turn the fuel cock
knob to this position when the engine is not
running.
ON:
With the fuel cock knob in this position,
fuel flows to the carburetors. Turn the fuel
cock knob to this position when starting the
engine and operating the watercraft.
RES:
This indicates reserve. With the fuel cock
knob in this position, the fuel reserve is
made available. Tur n the fuel cock knob to
this position if you run out of fuel while oper-
ating the watercraft. When this occurs,
refuel as soon as possible and be sure to
turn the fuel cock knob back to “ON”!

Cooling water pilot outlet
This watercraft is equipped with a cooling
water pilot outlet.
When the engine is running, cooling
water is circulated in the engine, and then it
is discharged from the pilot outlet.
To check for proper operation of the cool-
ing system, check that water is being dis-
charged from the pilot outlet. If water is not
being discharged from the outlet, cooling
water may not be circulating in the engine.
When this occurs, stop the engine and check
for the cause. (See pages 2-17 and 5-4 for
further instructions.)
NOTE:@ If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlet after the engine is started.

Steering system
Your watercraft can be steered by turning
the handlebars 1 the same direction you
wish to travel.
When the handlebars are turned, the
angle of the jet thrust nozzle 2 is changed,
and the direction of the watercraft is
changed accordingly. Since the strength of
the jet thrust determines the speed and
direction of a turn, the throttle must always
be open when attempting a turn, except at
trolling speed.

Shift lever
The shift lever is located on the starboard
side of the watercraft and is used to control
the reverse gate, which allows the watercraft
to move into reverse or forward.
When in the reverse position, the water-
craft can be launched from a trailer, or
backed up out of tight spots where you can-
not turn around easily.
To shift into reverse:
1. Release the throttle, and then let the
engine speed return to idle.
2. Pull the shift lever toward you.
WARNING@
Make sure that the throttle is com-
pletely released and that the engine is
at idle before shifting into reverse.

Do not use the reverse function to
slow down or stop the watercraft as it
could cause you to lose control, be
ejected, or impact the handlebars.

Use reverse for slow-speed maneuver-
ing only.

Make sure that there are no obstacles
or people behind you before shifting
into reverse.

Do not touch the reverse gate while the
shift lever is being operated, otherwise
you could be pinched.
@
To shift into forward:
1. Release the throttle, and then let the
engine speed return to idle.
2. Push the shift lever away from you.

Quick Shift Trim System
(QSTS) selector
The QSTS selector 1 is located at the
left handlebar grip and is used to adjust the
trim angle of the watercraft.
Operating the QSTS selector changes the
angle of the jet thrust nozzle vertically. This
changes the trim angle of the watercraft.
There are 5 positions: 2 bow down posi-
tions A and B, neutral “N,” and 2 bow up
positions C and D.
To change the trim angle:
1. Reduce engine speed to 3,400 r/min or
less.
2. Squeeze the shift lock lever 2, and then
turn the QSTS selector to the desired
position.
3. Release the shift lock lever to lock the
QSTS selector.
CAUTION:@ Do not turn the QSTS selector while
operating the watercraft at full throttle,
otherwise damage could occur to the
QSTS.
@
The neutral “N” position will provide good
performance for most operating conditions.
To enhance particular types of perfor-
mance, select bow down or bow up.
