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

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

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.

Such clothing includes thick, tightly woven,
sturdy and snug-fitting apparel such as den-
im, but does not include spandex or similar
fabrics, like those used in bicycle shorts. A full
wetsuit can also protect against hypothermia
(subnormal body temperature) and abra-
sions.
Footwear and gloves are recommended.
Eye protection is recommended to keep wind,
water, and glare from the sun out of your eyes
while you operate your watercraft. Restraining
straps for eyewear are made which are de-
signed to float should your eyewear fall in the
water.
You should grip the handlebars firmly and get
to a standing or kneeling position quickly.
Keep both feet or knees on the riding tray
when the watercraft is in motion.
EJU33170Operating positions
After you are underway, you may choose to
kneel or stand, depending upon watercraft
speed, your skill level, and your preference.
Here are some guidelines.
EJU33181Kneeling
It is easier to maintain your balance when
kneeling than when standing. This position is
recommended 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.)At very slow speeds, it may be necessary to
support your upper-body weight with your el-
bows resting on the gunwales, trailing your
legs in the water.
EJU33190Standing
After you are comfortable handling the water-
craft from a kneeling position, try standing as
the watercraft gains speed. The watercraft will
become easier to balance as the speed in-
creases, because jet thrust provides stability
as well as directional control. When you are
moving slowly, or preparing to stop, you will
probably need to return to the kneeling posi-
tion to maintain your balance.
EJU33071Starting the watercraft
WARNING
EWJ00711
To avoid collisions:

Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vi-
sion 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

WARNING
EWJ00671
Improper uprighting can cause injury.

Be sure to shut the engine off by pulling
on the engine shut-off cord (lanyard) to
remove the clip from the engine shut-off
switch.

Do not put your hands in the intake
grate.
If the watercraft capsizes, turn it over immedi-
ately.
Be sure to carefully follow the procedures be-
low to prevent injury, or damage to the water-
craft.
(1) Remove the clip from the engine shut-off
switch.
(2) Swim to the rear of the watercraft and up-
right it by turning it clockwise only.
If the port (left) side of the capsized wa-
tercraft is tilting up, push down on the
gunwale so that the port (left) side is
down before turning the watercraft clock-
wise. NOTICE: Do not turn the water-
craft over counterclockwise,
otherwise water can enter the engine,which can result in severe damage.
[ECJ00541]
(3) Start the engine and operate the water-
craft as straight as possible and above
planing speed for at least 2 minutes to
discharge any water remaining in the en-
gine compartment. (If the engine does
not start, see “Towing the watercraft” on
page 65 or “Submerged watercraft” on
page 65.) NOTICE: Do not operate the
engine at full throttle for at least 1
minute after the engine has been re-
started. Excessive water in the engine
compartment can splash into the en-
gine, which can result in severe dam-
age.
[ECJ00551]
To stabilize the watercraft when acceler-
ating to planing speed, maintain a low
center of gravity by operating it in the
kneeling position.

(5) Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See
page 45 for flushing procedures.)
(6) If the watercraft will be stored for a week
or more, lubricate internal engine compo-
nents to help prevent corrosion. (See
page 46 for lubrication procedures.)
(7) Rinse the engine and engine compart-
ment with a small amount of water.
NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.
[ECJ00571]
(8) Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3,
if necessary).
(9) Wipe the hull, steering pole, handlebars,
and jet unit dry with a clean cloth.
(10) Spray a rust inhibitor on metallic parts to
minimize corrosion.
(11) Allow the engine compartment to air dry
completely before installing the hood.

Transporting
WARNING
EWJ00750
Always turn the fuel cock knob to “OFF”
when transporting the watercraft, other-
wise fuel could leak out into the engine or
engine compartment, which would create
a fire hazard.
Transport this watercraft using a special trail-
er that incorporates a hole into which the pin
can be inserted and locked after passing it
through the bow rope hole.
After securing the bow with the pin, secure the
stern with ropes or tie downs routed over the
gunwales. Use a rubber shock cord to secure
the steering pole to the watercraft. NOTICE:
