Boarding and starting in deep
water
1. Swim to the rear of the watercraft. Attach
the engine shut-off cord to your wrist.
Attach the clip to the engine shut-off
switch.
2. Grasp the handlebars with both hands.
Pull your body up onto the riding tray and
balance there, using your elbows on the
gunwales for leverage.
3. Start the engine and begin to accelerate.
4. Continue to pull your body up onto the
watercraft as the watercraft speed
increases.
5. Bring your knees up onto the riding tray
and change to a kneeling position as
soon as you can do so.
WARNING@ Avoid forceful jet thrust and limited visi-
bility while reboarding. Get to standing
or kneeling position quickly, but do not
expose yourself to forceful jet thrust.

6. Move as far forward as possible without
interfering with the movement of the han-
dlebars. Keep your body perpendicular
to the water, with your weight forward
and low.
7. Once the bow drops, and the watercraft
has leveled out in the water and reached
planing speed, back off the throttle lever
and select your desired speed.
NOTE:@
The watercraft will become easier to bal-
ance as the speed increases, because jet
thrust provides stability as well as direc-
tional control.

It will take longer for a heavier operator to
reach planing speed than it will for a light
operator.

Boarding and starting in shallow
water
Be sure to learn the deep-water starting
method before operating the watercraft in
water where it is too deep for you to stand.
Do not try to start the watercraft in water
less than 60 cm (2 ft) deep.
1. Launch the watercraft into water.
2. Attach the engine shut-off cord to your
wrist. Attach the clip to the engine
shut-off switch.
3. Grip the handlebars with both hands.
Place one knee on the riding tray and
balance there.
4. Start the engine and begin to accelerate.
5. Pull your other knee up onto the riding
tray as the watercraft speed increases.
6. Move as far forward as possible without
interfering with the movement of the han-
dlebars. Keep your body perpendicular
to the water, with your weight forward
and low.
NOTE:@ The watercraft will become easier to bal-
ance as the speed increases, because jet
thrust provides stability as well as directional
control.

Operating positions
After you are underway, you may choose
to kneel or stand, depending upon water-
craft speed, your skill level, and your prefer-
ence. Here are some guidelines.
EJU01291
Kneeling
It is easier to maintain your balance when
kneeling than when standing. This position
is suggested when traveling at sub-planing
speeds. (At sub-planing speeds, there is a
wake, but the watercraft is moving through
the water rather than skimming on top of it.)
NOTE:@ At very slow speeds, it may be necessary to
support your upper-body weight with your
elbows resting on the gunwales, trailing your
legs in the water.
@
EJU01292
Standing
After you are comfortable handling the
watercraft from a kneeling position, try
standing as the watercraft gains speed. Sta-
bility increases when you are traveling at
planing speed. When you are moving slowly,
or preparing to stop, you will probably need
to return to the kneeling position to maintain
your balance.

Capsized watercraft
If the watercraft capsizes, turn it over
immediately.
Be sure to carefully follow the procedures
below to prevent injury or damage to the
watercraft.
WARNING@ IMPROPER UPRIGHTING CAN CAUSE
INJURY:

Shut the engine off by pulling on the
engine shut-off cord to remove the clip
from the engine shut-off switch.

Do not put your hands in the intake
grate.
@
CAUTION:@ Be sure to remove the clip from the
engine shut-off switch to shut the engine
off, otherwise the engine can overheat,
which can result in severe engine dam-
age.
@
1. Shut the engine off by removing the clip
from the engine shut-off switch.
2. Swim to the rear of the watercraft and
upright it by turning it clockwise only.
NOTE:@ If the port (left) side of the capsized water-
craft is tilting up, push down on the gunwale
so that the port (left) side is down before
turning the watercraft clockwise.
@
CAUTION:@ Do not turn the watercraft over counter-
clockwise, otherwise water can leak into
the carburetor and engine, which can
result in severe damage.

3. Start the engine and operate the water-
craft to discharge any water remaining in
the engine compartment. (If the engine
does not start, see page 5-6, “Towing the
watercraft” or page 5-7, “Submerged
watercraft.”)
NOTE:@
To efficiently discharge water from the
engine compartment, operate the water-
craft as straight as possible and above
planing speed for at least 2 minutes.

To stabilize the watercraft when accelerat-
ing to planing speed, maintain a low cen-
ter of gravity by operating it in the
kneeling position.

Turning the watercraft
Steering control depends on the combi-
nation of handlebar position and the amount
of throttle.
Water sucked in through the intake grate
is pressurized by the impeller in the jet
pump. As the pressurized water is expelled
from the pump through the jet thrust nozzle,
it creates thrust to move and steer the
watercraft. The higher the engine speed, the
more thrust is produced.
The amount of jet thrust, in addition to the
position of the handlebars, determines how
sharply you turn.
A. More throttle produces high thrust, so
the watercraft will turn more sharply.
B. Less throttle produces low thrust, so the
watercraft will turn more gradually.
C. Releasing the throttle lever completely
produces only minimum thrust. If you are
traveling at speeds above trolling, you
will have rapidly decreasing ability to
steer without throttle. You may still have
some turning ability immediately after
releasing the throttle lever, but once the
engine slows down, the watercraft will no
longer respond to handlebar input until
you apply throttle again or you reach a
trolling speed.
At trolling speed, the watercraft can be
turned gradually by handlebar position
alone using just the amount of thrust
available at idle.
D. If the engine is stopped while riding,
there is no thrust. The watercraft will go
straight even though the handlebars are
turned.
You need throttle to steer.

To maintain your balance, lean into a turn.
How much you lean depends on the tight-
ness of the turn and your traveling speed. In
general, the higher the speed or the sharper
the turn, the more you lean.
WARNING@ Do not release the throttle when trying to
steer away from objects—you need throt-
tle to steer. A collision could result in
severe injury or death.
