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

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.
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.
You will inevitably fall off, so be sure you know
how to get back on the watercraft once you
are away from shore.
EJU33102Boarding and starting in shallow water
Be sure to learn the deep-water starting meth-
od before operating the watercraft in water
where it is too deep for you to stand. (See
page 38 for the deep-water starting method.)
(1) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep from the bottom of the watercraft.
NOTICE: Never operate in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise
pebbles or sand could be sucked into
the jet intake, causing impeller dam-
age and engine overheating.
[ECJ00471]
(2) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch.
(3) Grip the handlebars with both hands.
Place one knee on the riding tray and bal-
ance there.
(4) Start the engine and begin to accelerate.
(5) Pull your other knee up onto the riding
tray as the watercraft speed increases.
(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.
TIP:
The watercraft will become easier to balance
as the speed increases, because jet thrust
provides stability as well as directional control.

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.

D. If the engine is stopped while riding, there
is no thrust. The watercraft will go straight
even though the handlebars are turned.
You need throttle to steer.
To maintain your balance, lean into a turn.
How much you lean depends on the sharp-
ness of the turn and your traveling speed. In
general, the higher the speed or the sharper
the turn, the more you lean.EJU33270Stopping the watercraft
The watercraft is not equipped with a sepa-
rate braking system. It is stopped by water re-
sistance when the throttle lever is released.
From full speed, the watercraft comes to a
complete stop in approximately 90 m (300 ft)
after the throttle lever is released or the en-
gine is stopped, although this distance will
vary depending on many factors, including
gross weight, water surface conditions, 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 ob-
stacle, apply throttle and turn in another direc-
tion.
WARNING
EWJ00720

Allow adequate stopping distance.

Take early action to avoid collisions. Re-
member, 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 slowing
down in case you need engine power to

Towing the watercraft
WARNING
EWJ00811

The operator of the towing boat must
keep speed to a minimum and avoid traf-
fic or obstacles which could be a hazard
to the operator on the watercraft.

The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
If the watercraft becomes inoperative in the
water, it can be towed to shore.
When the watercraft is towed using a towline,
the operator should ride the watercraft, hold-
ing onto the handlebars and supporting his or
her body weight on the riding tray. This will
help keep the bow of the watercraft out of the
water.
Use a towline that is three times the combined
length of the towing boat and the watercraft.Tow the watercraft using the bow rope hole
only.
Tow the watercraft at 5 mph (8 km/h) or less.
The bow must be kept up out of the water dur-
ing towing to prevent water from entering the
engine compartment.
EJU34731Submerged watercraft
If the watercraft is submerged or flooded with
water, follow the procedure below and consult
a Yamaha dealer as soon as possible. Failure
to do so could result in serious engine dam-
age.
(1) Beach the watercraft and remove the
hood.
(2) Turn the fuel cock knob to “OFF”.
(3) Turn the watercraft over far enough to
drain the water from the engine compart-
ment. NOTICE: Turning the watercraft
on its side with the hood removed
could cause damage to the steering
pole. Use two people to provide
enough support to make sure that the
steering pole is not damaged.
[ECJ00701]
(4) Turn the watercraft upright again.
(5) Have the watercraft inspected by a
Yamaha dealer as soon as possible.
NOTICE: Be sure to have a Yamaha
dealer inspect the watercraft. Other-
wise, serious engine damage could re-
sult.
