Safety information

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 collision 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 wa-
ter, commonly known as “bucketing”, and
the resulting strain on your neck could
cause choking, severe and permanent neck
injuries, or death. A helmet could also in-
crease 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 poten-
tial safety benefits outweigh its potential
risks for you? Consider your particular
riding conditions. Consider factors such as
your riding environment and your riding
style and ability. Also consider the likeli-
hood of traffic congestion, and the water
surface conditions.
If you decide to wear a helmet based upon
your riding circumstances, choose one
carefully. Look for a helmet designed for
personal watercraft use, if possible. If you
will be engaging in closed-course competi-
tion, follow the helmet requirements of the
sanctioning organization.

Never operate the watercraft after consum-
ing alcohol or taking other drugs.

For reasons of safety and proper care of the
watercraft, always perform the pre-opera-
tion checks listed on page 26 before operat-
ing the watercraft.

The operator should always keep both feet
or knees on the riding tray when the water-
craft is in motion. Lifting your feet increasesthe chances of losing your balance or hitting
objects outside the watercraft with your
feet.

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 water-
craft unsafe or illegal for use.

Attach the engine shut-off cord (lanyard) to
your left wrist and keep it free from the han-
dlebars so that the engine stops if you, the
operator, fall off. After riding, remove the
engine shut-off cord (lanyard) from the wa-
tercraft to avoid accidental starting or unau-
thorized use by children or others.

Scan carefully for swimmers, and stay
away from swimming areas. Swimmers are
hard to see and you could accidentally hit
someone in the water.

Hazard information

When transporting or storing your water-
craft, always turn the fuel cock knob to
“OFF”, 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 color-
less, 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 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 im-
mediately after releasing the throttle lever,
but once the engine slows down, the water-
craft will no longer respond to handlebar in-
put until you apply throttle again or you
reach trolling speed.
Practice turning in an open area without ob-
stacles until you have a good feel for this
maneuver.

This watercraft is 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.

Keep away from the intake grate while the
engine is on. Items such as long hair, loose
clothing, or PFD straps can become entan-
gled in moving parts, resulting in severe in-
jury or drowning.

Never insert any object into the jet thrust
nozzle 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 from
the engine shut-off switch before removing
any debris or weeds, which may have col-
lected around the jet intake.

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.

Safe boating rules
Your Yamaha watercraft is legally considered
a powerboat. Operation of the watercraft must
be in accordance with the rules and regula-
tions governing the waterway on which it is
used.

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, wa-
ters, and wildlife with respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you. Re-
member, 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 en-
joy.
Avoid riding close to shoreline homes and wa-
terfowl nesting areas or other wildlife areas,
and keep a respectful distance from fisher-
men, other boats, swimmers, and populated
beaches. When travel in areas like these is
unavoidable, ride slowly and obey all laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within regu-
lated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, 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. Dis-
pose of water and any fuel and oil residue in
the engine compartment according to local
regulations. 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 ourwaterways stay open for the enjoyment of a
variety of recreational opportunities.
