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 caus-
ing injury or death. Be alert to the possi-
bility 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
ride your watercraft without someone else
near by. If you ride further than swimming
distance from shore, you should ride 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 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.

Operation requirements
●Wear a personal flotation device (PFD).
All riders must wear an authority-
approved PFD that is 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 fab-
rics, like those used in bicycle shorts.

●Eye protection is recommended to keep
wind, water, and glare from the sun out of
your eyes while you operate your water-
craft. Restraining straps for eyewear are
made which are designed to float should
your eyewear fall in the water.
Footwear and gloves are recommended.

●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 pre-
operation checks listed on page 3-5
before operating the watercraft.
●The operator and passenger should
always keep both feet in the footwell 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. Do not give a ride
to a child whose feet cannot reach the
floor of the footwell.
●Passenger should firmly hold on to the
operator.
●Always consult your doctor on whether it
is safe for you to ride 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.
●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 1-14.)

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.

Watercraft characteristics
●Jet thrust turns the watercraft. Releasing
the throttle completely produces only min-
imum 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 han-
dlebar input until you open the throttle
again or you reach a trolling speed. Prac-
tice 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 pro-
duce some movement whenever the
engine is running. There is no “neutral”
position.
●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 into the jet thrust
nozzle 2 while the engine is running.
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, which may
have collected around the jet intake.

Safe boating rules
Your Yamaha watercraft is legally consid-
ered a powerboat. Operation of the water-
craft must be in accordance with the rules
and regulations governing the waterway on
which it is used.
EJU00322
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 excit-
ing 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 unavoid-
able, 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 refu-
eling. 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 enjoy-
ment of a variety of recreational opportuni-
ties.
