Safety information
The safe use and operation of this
watercraft is dependent upon the use of
proper riding techniques, as well as upon
the common sense, good judgment, and
expertise of the operator. Before using
this watercraft, make sure that its use is
permitted under local laws, bylaws and
regulations and always operate the
watercraft in full conformity with any
requirements and limitations imposed.
Every operator should know the following requirements before riding the watercraft.
Before operating the watercraft, read this
●
Owner’s/Operator’s Manual, the Riding
Practice Guide, and all warning and cau-
tion labels on the watercraft. These mate-
rials should give you an understanding of
the watercraft and its operation.
Never allow anyone to operate this water-
●
craft until they too have read this Owner’s/
Operator’s Manual, the Riding Practice
Guide and all warning and caution labels.
EJU01268
Limitations on who may
operate the watercraft
Yamaha recommends a minimum opera-
●
tor 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
●
operator only. Never have more than one
person on the watercraft at any time.
1-6
E
EJU01269
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,
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
●
shallow water.
Ride within your limits and avoid aggres-
●
sive maneuvers to reduce the risk of loss
of control, 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 (paralysis), facial injuries, and bro-
ken legs, ankles and other bones. Do not
jump wakes or waves.
Do not operate the watercraft in rough
●
water, bad weather or when visibility is
poor; this may lead to an accident causing injury or death. Be alert to the possibility of adverse weather. Take note of
weather forecasts and the prevailing
weather conditions before setting out on
your watercraft.
As with any water sport, you should not
●
operate your watercraft without someone
else near by. If you operate further than
swimming 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.
1-7
This watercraft is not equipped with light-
●
ing required for night operation. Do not
operate the watercraft after sunset or
before dawn, otherwise you increase the
risk of colliding with another boat, which
could result in severe injury or death.
EJU01270
Operation requirements
All riders must wear a personal flotation
●
device (PFD) that is approved by the
appropriate authorities and suitable for
personal watercraft use.
Wear protective clothing. Severe internal
●
injuries can occur if water is forced into
body cavities as a result of falling into
water or being near the jet thrust nozzle.
Normal swimwear does not adequately
protect against forceful water entry into
rectum or vagina. 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 denim, but does not include
spandex or similar fabrics, like those used
in bicycle shorts.
E
1
Authority-approved PFD
2
Wetsuit bottom
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 eyewear fall in the water.
Footwear and gloves are recommended.
1-8
You must decide whether to wear a hel-
●
met while you ride for recreation. You
should know that a helmet could help pro-
tect you in certain kinds of accidents and
that it could injure you in others.
A helmet is designed to provide some
head protection. Although helmets cannot
protect against all foreseeable impacts, a
helmet might reduce your injuries in a col-
lision with a boat or other obstacle.
A helmet may have potential safety haz-
ards, as well. Falling into the water could
risk the chance of the helmet catching
water, commonly known as “bucketing,”
and the resulting strain on your neck
could cause choking, severe and perma-
nent neck injuries, or death. A helmet
could also increase the risk of an accident
if it reduces your vision or hearing, or if it
distracts you or increases your fatigue.
How should you decide if a helmet’s
potential safety benefits outweigh its
potential risks for you? Consider your par-
ticular riding conditions. Consider factors
such as your riding environment and your
riding style and ability. Also consider the
likelihood of traffic congestion, and the
water surface conditions. If you decide to
wear a helmet based upon your riding cir-
cumstances, choose one carefully. Look
for a helmet designed for personal water-
craft use, if possible. If you will be engag-
ing in closed-course competition, follow
the helmet requirements of the sanction-
ing organization.
NEVER operate the watercraft after con-
●
suming alcohol or taking other drugs.
For reasons of safety and proper care of
●
the watercraft, always perform the preoperation checks listed on page 3-5
before operating the watercraft.
The operator should always keep both
●
feet or knees on the riding tray when the
watercraft is in motion. Lifting your feet
increases your chances of losing your
balance, and your feet being hit by objects
outside the watercraft.
Always consult your doctor on whether it
●
is safe for you to operate this watercraft if
you are pregnant or in poor health.
Do not attempt to modify this watercraft!
●
Modifications to your watercraft may
reduce safety and reliability, and render
the watercraft unsafe or illegal for use.
E
1-9
E
Attach the engine shut-off cord (lanyard)
●
to wrist and keep it free from the handle-
bars so that the engine stops if the opera-
tor falls off. After riding, remove the
engine shut-off cord from the watercraft to
avoid accidental starting or unauthorized
use by children or others.
Scan carefully for swimmers, and stay
●
away from swimming areas. Swimmers
are hard to see and you could acciden-
tally hit someone in the water.
Avoid being hit by another boat! You
●
should always take the responsibility to
watch for traffic; other boaters may not be
watching for you. If they do not see you,
or you maneuver more quickly than other
boaters expect, you risk a collision.
Maintain a safe distance from other boats
●
or watercraft, and also watch for boats’ ski
ropes or fishing lines. Obey the “Safe
boating rules” and be sure to check
behind you before making a turn. (See
Safe boating rules on page 1-12.)
EJU01382
Recommended equipment
The following items should be carried on
board your watercraft:
Sound-signaling device
●
You should carry a whistle or other soundsignaling device that can be used to signal other boats.
Visual distress signals
●
It is recommended that an authorityapproved pyrotechnic device be stored in
a waterproof container on your watercraft.
A mirror can also be used as an emergency signal. Contact your Yamaha
dealer for more information.
Watch
●
A watch is helpful so you will know how
long you have been operating.
Towline
●
A towline can be used to tow a disabled
watercraft in an emergency.
1-10
E
EJU01003
Hazard information
When transporting or storing your water-
●
craft, always place the fuel cock knob in
the “OFF” position, otherwise gasoline
may overflow from the carburetor.
Never start the engine or let it run for any
●
length of time in an enclosed area.
Exhaust fumes contain carbon monoxide,
a colorless, odorless gas that may cause
loss of consciousness and death within a
short time. Always operate the watercraft
in an open area.
EJU01271
Watercraft characteristics
Jet thrust turns the watercraft. 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, but once the engine slows down,
the watercraft will no longer respond to
handlebar input until you apply throttle
again or you reach a trolling speed. Practice turning in an open area without
obstructions until you have a good feel for
this maneuver.
This watercraft are water-jet propelled.
●
The jet pump is directly connected to the
engine. This means that jet thrust will produce some movement whenever the
engine is running. There is no “neutral”
position.
1-11
E
Keep away from intake grate 1 while the
●
engine is on. Items such as long hair,
loose clothing, or PFD straps can become
entangled in moving parts resulting in
severe injury or drowning.
Never insert any object in the jet thrust
●
nozzle 2. Severe injury or death could
result from coming in contact with the
rotating parts of the jet pump.
Stop the engine and remove the clip 3
●
from the engine shut-off switch 4 before
removing any debris or weeds that may
have collected around the jet intake.
EJU01005
Safe boating rules
Your Yamaha watercraft is legally considered a powerboat. Operation of the watercraft must be in accordance with the rules
and regulations governing the waterway on
which it is used.
Avoid forceful jet thrust and limited visibil-
●
ity while reboarding. Get to standing or
kneeling position quickly, but do not
expose yourself to forceful jet thrust.
1-12
EJU01006
Enjoy your watercraft
responsibly
You share the areas you enjoy when
riding your watercraft with others and with
nature. So your enjoyment includes a
responsibility to treat these other people,
and the lands, waters, and wildlife with
respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you.
Remember, for example, that the sound of
your watercraft may be music to you, but it
could be just noise to others. And the exciting splash of your wake can make waves
others won’t enjoy. Avoid riding close to
shoreline homes and waterfowl nesting
areas or other wildlife areas, and keep a
respectful distance from fishermen, other
boats, swimmers, and populated beaches.
When travel in areas like these is unavoidable, ride slowly and obey all laws.
Remember that pollution can be harmful
to the environment. Do not refuel or add oil
where a spill could cause damage to nature.
Remove your watercraft from the water and
move it away from the shoreline before refueling. And keep your surroundings pleasant
for the people and wildlife that share the
waterways: don’t litter!
When you ride responsibly, with respect
and courtesy for others, you help ensure
that our waterways stay open for the enjoyment of a variety of recreational opportunities.

Cooling water pilot outlet
This watercraft is equipped with a cooling
water pilot outlet.
When the engine is running, cooling
water is circulated in the engine, and then it
is discharged from the pilot outlet.
To check for proper operation of the cooling system, check that water is being discharged from the pilot outlet. If water is not
being discharged from the outlet, cooling
water may not be circulating in the engine.
When this occurs, stop the engine and
check for the cause. (See pages 2-9 and 5-3
for further instructions.)
NOTE:
@
If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlet after the engine is started.
@
EJU01021
Steering system
Your watercraft can be steered by turning
the handlebars 1 the same direction you
wish to travel.
When the handlebars are turned, the
angle of the jet thrust nozzle 2 is changed,
and the direction of the watercraft is
changed accordingly. Since the strength of
the jet thrust determines the speed and
direction of a turn, the throttle must always
be open when attempting a turn, except at
trolling speed.
