age of 16 years old.
Adults must supervise use by minors.
Know your local operator age and training
requirements.
This watercraft is designed to carry the op-
erator and up to 2 passengers. Never ex-
ceed the maximum load limit or allow more
than 3 persons (or 2 persons if a water-skier
is being pulled) to ride the watercraft at any
time.
Do not operate the watercraft with any pas-
sengers on board until you have consider-
able practice and experience riding alone.

To enhance particular types of performance,
select bow down or bow up.
EJU31330Bow down
Turn the QSTS selector to (a) or (b) and the
bow will go down while the watercraft is on
plane.
Bow down puts more of the bow in the water.
This gives the watercraft more “hook”, which
enhances turning performance. This position
will also help the watercraft get up on plane
more quickly.
At higher speeds, however, the watercraft will
have a greater tendency to “bow steer” and
follow waves and wakes in the water. Fuel
economy and maximum speed are also re-
duced.
EJU31340Bow up
Turn the QSTS selector to (c) or (d) and the
bow will go up while the watercraft is on plane.
Bow up puts less of the bow in the water.
There is less water resistance, so straight-ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the watercraft
may tend to “porpoise” (hop in the water). If
the watercraft is porpoising, select neutral or
bow down.
EJU37370Handgrips
The handgrips provide handholds for a spot-
ter when facing rearward. WARNING! Do not
use the handgrip to lift the watercraft. The
handgrip is not designed to support the
watercraft’s weight. If the handgrip
breaks, the watercraft could fall, which
could result in severe injury.

Operating your watercraft EJU32961Getting 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 10.
These materials should give you an under-
standing of the watercraft and its operation.
Remember: This watercraft is designed to
carry the operator and up to 2 passengers.
Never exceed the maximum load limit or allow
more than 3 persons (or 2 persons if a water-
skier is being pulled) to ride the watercraft at
any time.
EJU33001Learning to operate your watercraft
Before operating the watercraft, always per-
form the pre-operation checks listed on page
45. 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). All
riders 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 and vagi-
na. All riders 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 Maximum load:
240 kg (530 lb)
Load is the total weight of cargo, oper-
ator, and passengers.

EJU37460Boarding 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
reboarding grip 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 (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch.
(4) Grip the handlebars with both hands,
place both feet on the floor of the footwell,
start the engine, and then look in all direc-
tions before starting off.
TIP:
This watercraft is equipped with a reboarding
step, which you can lower to make reboarding
easier. The step returns automatically to the
up position after you have boarded.
EJU33164Boarding with passengers
WARNING
EWJ00660
Severe internal injuries can occur if water
is forced into body cavities as a result of
being near the jet thrust nozzle. Do not ap-
ply throttle until the passengers are seated
with their feet on the floor of the footwell
and are securely holding on to the person
in front of them or to the handgrip provid-
ed.
TIP:
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.

B. Less throttle produces lower thrust, so
the watercraft will turn more gradually.
C. Releasing the throttle lever completely
produces only minimum thrust. If you are
traveling at speeds above trolling, you will
have rapidly decreasing ability to steer
without throttle. You may still have some
turning ability immediately after releasing
the throttle lever, but once the engine
slows down, the watercraft will no longer
respond to handlebar input until you ap-
ply throttle again or you reach trolling
speed.
At trolling speed, the watercraft can be
turned gradually by handlebar position
alone using just the amount of thrust
available at idle.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.
This model is equipped with the Yamaha En-
gine Management System (YEMS) that in-
cludes an off-throttle steering (OTS) system.
It will activate at planing speeds should you
attempt to steer the watercraft after releasing
the throttle lever (see condition C above).
The OTS system assists in turning by continu-
ing to supply some thrust while the watercraft
is decelerating, but you can turn more sharply
if you apply throttle while turning the handle-
bars. The OTS system does not function be-
low planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar in-
put until you apply throttle again or you reach
trolling speed.
EJU37510Stopping 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 130 m (430 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
