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, ob-
jects, 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 un-
derstand where you are going.

Avoid areas with submerged objects or
shallow water.

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

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

Ride within your limits and avoid aggressive
maneuvers to reduce the risk of loss of con-
trol, 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 (pa-
ralysis), facial injuries, and broken legs, an-kles, and other bones. Do not jump wakes
or waves.

Do not operate the watercraft in rough wa-
ter, bad weather, or when visibility is poor;
this may lead to an accident causing injury
or death. Be alert to the possibility of ad-
verse weather. Take note of weather fore-
casts and the prevailing weather conditions
before setting out on your watercraft.

As with any water sport, you should not op-
erate your watercraft without someone else
nearby. If you operate further than swim-
ming 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 from the bottom of the water-
craft, otherwise you increase your chance
of hitting a submerged object, which could
result in injury.

This watercraft is not equipped with lighting
required for night operation. Do not operate
the watercraft after sunset or before dawn,
otherwise you increase the risk of colliding

Pour 2-stroke engine oil into a clean contain-
er, and then add gasoline. To mix them thor-
oughly, shake the container from side to side.
EJU31912Filling the fuel tank
(1) Lift the steering pole and support it with
the lock pin.
(2) Remove the hood. (See page 17 for hood
removal and installation procedures.)
(3) Remove the fuel tank filler cap, and then
slowly add premixed fuel to the fuel tank.
Stop filling when the fuel level just reach-
es the bottom of the filler tube. Do not fill
up the filler tube. Because fuel expands
when it heats up, heat from the engine or
the sun can cause fuel to spill out of thefuel tank. Do not leave the watercraft with
a full tank in direct sunlight.
(4) Wipe up any spilled fuel immediately.
(5) Install the fuel tank filler cap and the
hood. Make sure that the fuel tank filler
cap is securely closed before operating
the watercraft.

(3) Turn the fuel cock knob to “ON”.
(4) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch. It is not pos-
sible to start the engine with the clip re-
moved from the engine shut-off switch.
WARNING! Check that the engine
shut-off cord (lanyard) is attached cor-
rectly. If the engine shut-off cord (lan-
yard) is not attached correctly, it may
not pull free when the operator fallsoff, allowing the watercraft to continue
to run and cause an accident.

(5) Pull the choke knob all the way out to
start a cold engine.
TIP:
The choke should not be used when the en-
gine is warm.
(6) While lightly squeezing the throttle lever,
push the start switch (green button), and
then release the switch as soon as the
engine starts to run. If the engine does
not start in 5 seconds, release the start
switch, wait 15 seconds, and then try
again. WARNING! Do not apply too
much throttle when starting the en-
gine, otherwise the watercraft will ac-
celerate unexpectedly. This could
cause a collision or cause the opera-

Operating your watercraft EJU32921Getting to know your watercraft
Operating your watercraft requires skills ac-
quired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneu-
vers.
Operating your new watercraft can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar-
ize yourself with the operation of the water-
craft to achieve the skill level necessary to
enjoy riding safely.
Before operating this watercraft, read this
owner’s/operator’s manual, the Riding Prac-
tice Guide, the Riding Instruction card, and all
labels on the watercraft. Pay particular atten-
tion to the safety information on page 7.
These materials should give you an under-
standing of the watercraft and its operation.
Remember: This watercraft is designed to
carry the operator only. Never have more than
one person on the watercraft at any time.
EJU32981Learning to operate your watercraft
WARNING
EWJ00500

Do not apply throttle when anyone is at
the rear of the watercraft—turn the en-
gine off or keep it at idle. Water and/or
debris exiting the jet thrust nozzle can
cause severe injury.

Avoid the forceful jet thrust and make
sure that your visibility is not limited
while reboarding. Get to a standing or
kneeling position quickly, but do not ex-
pose yourself to the forceful jet thrust.
Before operating the watercraft, always per-
form the pre-operation checks listed on page
26. The short time spent checking the water-craft will reward you with added safety and re-
liability.
Check local laws before operating your water-
craft.
Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other watercraft. Select a wide area to
learn in, where there is good visibility and light
boat traffic.
Use the buddy system—operate with some-
one nearby. Scan constantly for people, ob-
jects, and other watercraft. Be alert for
conditions that limit your visibility or block your
vision of others.
Attach the engine shut-off cord (lanyard) to
your left wrist and keep it free from the handle-
bars so that the engine stops if you, the oper-
ator, fall off.
Wear a personal flotation device (PFD). The
operator must wear a PFD that is approved by
the appropriate authorities and is suitable for
personal watercraft use.
Wear protective clothing. Severe internal inju-
ries can occur if water is forced into body cav-
ities as a result of falling into the water or
being near the jet thrust nozzle. Normal swim-
wear does not adequately protect against
forceful water entry into the rectum or vagina.
The operator must wear a wetsuit bottom or
clothing that provides equivalent protection.

EJU33121Boarding and starting in deep water
WARNING
EWJ01260
Be sure the operator have practiced
boarding from the water while still close to
shore before riding. A person who has
made many unsuccessful attempts to get
back on the watercraft may become fa-
tigued and suffer from exposure, increas-
ing the risk of injury and drowning.
(1) Swim to the rear of the watercraft. Attach
the engine shut-off cord (lanyard) to your
left wrist, and then attach the clip to the
engine shut-off switch.
(2) Grip the handlebars with both hands. Pull
your body up onto the riding tray and bal-
ance 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 in-
creases.
(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
visibility while reboarding. Get to a
standing or kneeling position quickly,
but do not expose yourself to the
forceful jet thrust.
[EWJ00631]
(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 and
select your desired speed.
TIP:

The watercraft will become easier to bal-
ance as the speed increases, because jet
thrust provides stability as well as direction-
al control.

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