Safety information

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 pro-
tect against all foreseeable impacts, a hel-
met 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
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 poten-
tial safety benefits outweigh its potential
risks for you? Consider your particular rid-
ing 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-op-
eration checks listed on page 39 before op-
erating 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 increases the chances of losing your balance or hit-
ting 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 re-
duce safety and reliability, and render the
watercraft unsafe or illegal for use.
Attach the engine shut-off cord (lanyard) to
y o u r l ef t w r is t an d k ee p i t fr e e f r o m t h e h an -
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 un-
authorized 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.

EJU30872
Hazard information
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.
Do not touch the hot oil tank, muffler, or en-
gine during or immediately after engine op-
eration; they can cause serious burns.
EJU30883
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 wa-
tercraft will no longer respond to handlebar
input until you apply throttle again or you
reach trolling speed.
Practice turning in an open area without
obstacles until you have a good feel for this
maneuver.
This watercraft is water-jet propelled. The
jet pump is directly connected to the en-
gine. 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. This will improve
visibility and limit exposure to jet thrust.
EJU30971
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.
