EJU30750
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, 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

EJU35930Steering system
Your watercraft can be steered by turning the
handlebars in the direction you wish to travel.
When the handlebars are turned, the angle of
the jet thrust nozzle is changed, and the direc-
tion of the watercraft is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn, ex-
cept at trolling speed.
The angle of the jet thrust nozzle can be ad-
justed to suit operator preference. (See page
53 for adjustment procedures.)
EJU31270Steering pole
The steering pole varies in height with the op-
erator’s posture, enabling the operator to as-
sume various riding positions.
When removing the hood for pre-operation
checks, maintenance, etc., lift the steering
pole and use the lock pin to support it. Move
the lock pin into the detent. Make sure that the
lock pin is returned to the stowed position af-
ter installing the hood.

plugs, smoky exhaust, and heavy car-
bon deposits.
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.
EJU31910Filling the fuel tank
CAUTION:
ECJ00290
Be careful when refueling. Avoid getting
water and other contaminants in the fuel
tank. Contaminated fuel can cause poor
running and engine damage.
(1) Lift the steering pole and support it with
the lock pin.
(2) Remove the hood. (See page 18 for hood
removal and installation procedures.)
(3) Remove the fuel tank filler cap, and then
slowly add the premixed fuel to the fueltank. Stop filling when the fuel level just
reaches the bottom of the filler tube.
(4) Install the fuel tank filler cap and the
hood.
NOTE:
The hood must be removed in order to view
the fuel level in the fuel tank while adding fu-
el.
Be careful not to spill fuel or overfill the fuel
tank.
Do not fill up the filler tube because fuel ex-
pands as it warms up and could overflow.

EJU32280Pre-operation check points EJU32290Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, lift the
steering pole and support it with the lock pin,
and then remove the hood. (See page 18 for
hood removal and installation procedures.)
Leave the engine compartment open for a few
minutes to allow any fuel vapors to escape.
While the engine compartment is open, check
for loose electrical connections.
WARNING
EWJ00460
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak or
a loose electrical connection.
EJU32350Hull and deck
Check the hull and deck for cracks and other
damage. If any damage is found, have a
Yamaha dealer repair the watercraft.
EJU32360Fuel system
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
52 for check points and correct procedures.)(1) Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
(2) Remove the hood. (See page 18 for hood
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 26 for
filling procedures.)
(4) Install the fuel tank filler cap and the
hood.
EJU32420Water separator
Check the water separator for water. The wa-
ter separator retains any water that may have
entered through the fuel tank breather hose if
the watercraft was capsized. Normally, the
water separator is empty.
If water remains in the water separator, drain
it by removing the drain screw. Place a drain
pan under the water separator to catch the

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 to your left
wrist and keep it free from the handlebars so
that the engine stops if you, the operator, 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.
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.
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.
EJU33180Kneeling
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.)
NOTE:
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.
EJU33070Starting the watercraft
WARNING
EWJ00700
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
understand where you are going. Avoid
areas with submerged objects or shal-
low 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 throttle to steer.
Practice deep-water starting near shore
before riding in deep water.
The watercraft is less stable when at a stand-
still or at a slow speed. It takes skill to keep the
watercraft upright when starting.
Even though it is easier to start in shallow wa-
ter, you must learn deep-water boarding first.

(2) Swim to the rear of the watercraft and up-
right it by turning it clockwise only.
NOTE:
If the port (left) side of the capsized watercraft
is tilting up, push down on the gunwale so that
the port (left) side is down before turning the
watercraft clockwise.
CAUTION:
ECJ00520
Do not turn the watercraft over counter-
clockwise, otherwise water can enter 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 “Towing the water-
craft” on page 66 or “Submerged water-
craft” on page 67.)
NOTE:
To efficiently discharge water from the en-
gine compartment, operate the watercraft
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 center
of gravity by operating it in the kneeling po-
sition.
EJU33240Turning the watercraft
Steering control depends on the combination
of handlebar position and the amount of throt-
tle.
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 pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.

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 thegunwale. Use a rubber shock cord to secure
the steering pole.
CAUTION:
ECJ00630
Do not route ropes or tie downs over the
steering pole, as they could damage it.
Also, wrap the ropes or tie downs with
towels or rags where they touch the
body of the watercraft to avoid scratch-
ing or damage.
Do not transport the watercraft with the
steering pole up, otherwise the steering
pole could be damaged.
