Wear protective clothing. Severe internal
injuries can occur if water is forced into body
cavities as result of falling into the water or
being near the jet thrust nozzle. Normal
swimwear does not adequately protect
against forceful water entry into rectum and
vagina. All riders must wear a wetsuit bot-
tom or clothing that provides equivalent pro-
tection.
Such clothing includes thick, tightly
woven, sturdy and snug-fitting apparel such
as denim, 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 abrasions.
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 designed to float should your eye-
wear fall in the water.
You should grip the handlebars firmly and
keep both feet on the floor of the footwell. Do
not attempt to ride with passengers until
your operating skills are fully developed.
EJU01865
Riding watercraft with
passengers
When 2 or 3 persons (including the oper-
ator) are on board, the watercraft handles
differently, and is not as easy to maneuver,
so operating it requires a higher degree of
skill. Before attempting to operate the water-
craft with passengers on board, the operator
must practice operating the watercraft alone
enough to be able to acquire the necessary
skills. The passengers must always wear an
authority-approved PFD that is approved by
the appropriate authorities and wetsuit bot-
tom or equivalent.
WARNING@ Do not apply throttle when anyone is at
rear of watercraft. Turn engine off or keep
engine at idle. Water and/or debris exit-
ing the jet thrust nozzle can cause severe
injury. Passengers should not attempt to
board the watercraft if the operator is
applying throttle.
Do not give a ride to children whose feet
cannot reach the floor of the footwell. Pas-
sengers should hold on firmly to the person
in front of them and keep both feet in the
footwell.
WARNING@ When passengers are on board, make
sure that they are holding on firmly and
have feet in the footwell before you start
to accelerate.
When pulling a skier, the spotter should
face to the rear while holding the handgrip
with both hands. The spotter should always
sit astride the seat with his or her feet placed
firmly on the floor of the footwell for proper
balance. Follow all local laws regarding ski-
ing such as skier-down flags, rearward-fac-
ing spotter, and other requirements.

Starting the watercraft
WARNING@ Scan constantly for people, objects,
and other watercraft. Be alert for con-
ditions 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 water-
craft 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 sub-
merged 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 throttle to steer.
Practice reboarding in shallow water
before riding in deep water.

Boarding and starting in deep
water
WARNING@ Operator and passenger should prac-
tice getting on board in shallow water
before riding in deep water. Boarding
in deep water requires more skill.
The fatigue and exposure that could
result after unsuccessful attempts to
get back on the watercraft may
increase the risk of injuries and drown-
ing.
EJU01838
Boarding alone
1. Swim to the rear of the watercraft and
place both hands on the boarding plat-
form, pull yourself up, and then grasp the
handgrip with one hand.
2. Pull yourself up to a kneeling position on
the platform, and then move to the seat
and sit astride.
3. Attach the engine shut-off cord to your
left wrist, and then install the clip to the
engine shut-off switch.
4. Grip the handlebars firmly with both
hands, place both feet on the floor of the
footwell, start the engine, and then look
in all directions before starting off.
WARNING@ Before starting off, make sure that there
are no boats, obstructions, or swimmers
around you.

Boarding with passengers
WARNING@ Severe internal injuries can occur if
water is forced into body cavities as a
result of being near the jet thrust nozzle.
Do not apply throttle until each passen-
ger is seated with his or her feet on the
floor of the footwell and is holding on to
the person in front of him or her.
1. Climb on board as noted in the previous
section, and sit astride the seat. Attach
the engine shut-off cord to your left wrist,
and then install the clip to the engine
shut-off switch.
2. Have the passenger move to the rear of
the watercraft.
3. Have the passenger get on board and sit
on the seat. If a second passenger is
getting on, have him or her follow the
same procedure.
NOTE:@ When a passenger is getting on board, both
he and the operator should try to balance
the watercraft.
4. The operator should check to see that
the passengers have their feet on the
floor of the footwell and that they are
securely holding on to the person in front
of them.
5. Start the engine, look in all directions,
and then accelerate to planing speed.
WARNING@ Before starting off, make sure that there
are no boats, obstructions, or swimmers
around you.

NOTE:@ The heavier the total weight of the operator
and passengers, the more difficult it will be
to balance the watercraft. Do not operate the
watercraft when the total weight exceeds
240 kg (530 lb) including any cargo. If it is
difficult to balance the watercraft at a stand-
still, proceed as follows:
1. The passenger must steady the water-
craft while the operator is boarding. The
operator pulls him or herself up to a
kneeling position on the platform, and
then moves to the seat and sits astride to
balance the watercraft.
2. The operator attaches the engine shut-
off cord to his or her left wrist, and then
installs the clip to the engine shut-off
switch.
3. The operator starts the engine and lets it
run at idle.
4. The passenger pulls him or herself up to
a kneeling position, and then crawls onto
the seat as the watercraft accelerates.
5. The operator gradually increases speed
to balance the watercraft.
EJU01810
Capsized watercraft
If the watercraft capsizes, follow the pro-
cedures below carefully to prevent damage
or injury.
WARNING@ IMPROPER UPRIGHTING CAN CAUSE
INJURY:
Make sure that the engine shut-off
cord is removed from the engine shut-
off switch.
Do not put your hand in the intake
grate.
Watch so you are not hit by the water-
craft as it comes over.

WARNING@ Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.
When operating at higher speeds,
make gradual turns or slow down
before turning. Sharp high-speed turns
may cause the watercraft to slide side-
ways or spin, throwing the operator
and passengers overboard which
could cause an injury.
@
This model has the Yamaha Engine Man-
agement System (YEMS) that includes an
Off-Throttle Steering (OTS) system. It will
activate at planing speeds should you
attempt to steer the watercraft after releas-
ing the throttle lever (see condition C
above). The OTS system assists in turning
by continuing to supply some thrust while
the watercraft is decelerating, but you can
turn more sharply if you apply throttle while
turning the handlebars. The OTS system
does not function below planing speeds or
when the engine is off. Once the engine
slows down, the watercraft will no longer
turn in response to handlebar input until you
apply throttle again or you reach trolling
speed.

Stopping the watercraft
The watercraft is not equipped with a sep-
arate braking system. It is stopped by water
resistance when the throttle lever is
released. From full speed, the watercraft
comes to a complete stop in approximately
100 m (330 ft) after the throttle is released
and the engine is stopped, although this dis-
tance will vary depending on many factors,
including gross weight, water surface condi-
tions, and wind direction. The watercraft
slows down as soon as the throttle lever is
released, but will coast for a distance before
fully stopping. If you are not sure you can
stop in time before hitting an obstacle, apply
throttle and turn in another direction.
WARNING@ Allow adequate stopping distance.
Take early action to avoid collisions.
Remember, watercraft and other boats
do not have brakes.
Operate defensively at safe speeds
and keep a safe distance away from
people, objects, and other watercraft
to give you time to stop.
Do not shut the engine off when slow-
ing down in case you need engine
power to steer away from a boat or
other obstacle that comes into your
path.
Do not use the reverse function to
slow down or stop the watercraft as it
could cause you to lose control, be
ejected, or impact the handlebars.

Storage
WARNING@ Always place the watercraft upright in a
horizontal position when storing it, oth-
erwise fuel could leak out into the engine
or engine compartment, which could
result in a fire hazard.
@
Storage for prolonged periods of time,
such as winter storage, requires preventa-
tive maintenance to ensure against deterio-
ration. It is advisable to have the watercraft
serviced by a Yamaha dealer prior to stor-
age. However, the following procedures can
be performed by the owner.
EJU01813
Flushing the cooling system
Flushing the cooling system is essential
to prevent the cooling system from being
clogged with salt, sand, or dirt.
CAUTION:@ Do not supply water to the cooling
water passages when the engine is not
running. The water could flow back
through the muffler into the crankcase
causing severe engine damage.
Do not run the engine for more 15 sec-
onds without supplying water, other-
wise the engine may overheat.
