Cruising limitations

Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vision
of others.

Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.

Do not follow directly behind watercraft or
other boats.

Do not go near others to spray or splash
them with water.

Avoid sharp turns or other maneuvers
that make it hard for others to avoid you or
understand where you are going.

Avoid areas with submerged objects or
shallow water.

Take early action to avoid collisions.
Remember, watercraft and other boats do
not have brakes.

Do not release the throttle when trying to
steer away from objects—you need throt-
tle to steer. Always check throttle and
steering controls before starting the
watercraft.

Ride within your limits and avoid aggres-
sive maneuvers to reduce the risk of loss
of control, ejection, and collision.

This is a high performance boat—not a
toy. Sharp turns or jumping wakes or
waves can increase the risk of back/spinal
injury (paralysis), facial injuries, and bro-
ken legs, ankles and other bones. Do not
jump wakes or waves.

Do not operate the watercraft in rough
water, bad weather or when visibility is
poor; this may lead to an accident caus-
ing injury or death. Be alert to the possi-
bility of adverse weather. Take note of
weather forecasts and the prevailing
weather conditions before setting out on
your watercraft.

As with any water sport, you should not
operate your watercraft without someone
else nearby. If you operate further than
swimming distance from shore, you
should be accompanied by another boat
or watercraft, but make sure you stay a
safe distance away. It’s good, common
sense!

Never operate in water that is less than
60 cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged
object, which could result in injury.

Hood
The hood is secured at the rear by a
latch.
Lift the steering pole and support it with
the lock pin before removing the hood.
To remove the hood:
1. Turn the latch knob 1 to the open posi-
tion, and then pull up on the hood
latch2 to unlatch the hood.
2. Grasp the hood using the handgrips 3
provided at the front and rear side of the
hood. Lift the hood up and to the rear to
remove it.
To install the hood:
1. Position the hood on the deck so the two
projections at the front of the hood fit
under the two stays on the deck.

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 2-9 and 5-3
for more information.)
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.

Water discharge may not be constant at
idle, therefore, open the throttle a little to
check that water discharges properly.

EJU01021
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.

Steering pole
The steering pole varies in height with the
operator’s posture, enabling the operator to
assume various riding positions.
When removing the hood for pre-opera-
tion checks, maintenance, etc., lift the steer-
ing pole 1 and use the lock pin 2 to
support it. Move the lock pin into the detent.
Make sure the lock pin is returned to the
stowed position after installing the hood.

Filling the fuel tank
CAUTION:@ Be careful when refueling. Avoid getting
water or other contaminants in the fuel
tank. Contaminated fuel can cause poor
running or engine damage.
@
1. Lift the steering pole and support it with
the lock pin.
2. Remove the hood.
3. Open the fuel tank filler cap, and slowly
add the premixed fuel to the fuel tank.
4. Stop filling when the fuel level just
reaches the bottom of the filler tube.
NOTE:@
The hood must be removed in order to
watch the fuel level in the fuel tank while
adding fuel.

Be careful not to spill fuel or overfill the
tank.

Do not fill into the filler tube because fuel
could overflow.
@
Fuel tank capacity:
Total: 18 L (4.8 US gal, 4.0 Imp gal)
Reserve: 5.5 L
(1.45 US gal, 1.21 Imp gal)
