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 con-
suming 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 27 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 increases
the 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 to your left
wrist and keep it free from the handlebars

so that the engine stops if you, the operator,
fall off. After riding, remove the engine shut-
off cord from the watercraft to avoid acci-
dental starting or unauthorized use by chil-
dren 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.

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 if you ma-
neuver more quickly than other boaters ex-
pect, you risk a collision.

Maintain a safe distance from other boats
and watercraft, and also watch for ski ropes
or fishing lines. Obey the “Safe boating
rules” and be sure to check behind you be-
fore making a turn. (See “Safe boating
rules” on page 14.)
EJU30840
Recommended equipment
The following items should be carried on
board your watercraft:

Sound-signaling device
You should carry a whistle or other sound-
signaling device that can be used to signal
other boats.

Visual distress signals
It is recommended that a pyrotechnic de-
vice, which is approved by the appropriate
authorities, be stored in a waterproof con-
tainer on your watercraft. A mirror can also
be used as an emergency signal. Contact a
Yamaha dealer for more information.

Watch
A watch is helpful so you will know how long
you have been operating the watercraft.

Towline
A towline can be used to tow a disabled wa-
tercraft in an emergency.

EJU30850
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.
EJU30880
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.

NOTE:
Make sure that the hood is properly secured
before operating the watercraft.
EJU31090Fuel tank filler cap
To remove the fuel tank filler cap, turn it coun-
terclockwise.
NOTE:
Make sure that the fuel tank filler cap is se-
curely closed before operating the watercraft.
EJU31120Fuel cock knob
The fuel cock supplies fuel from the fuel tank
to the carburetors.The fuel cock knob positions are explained as
follows and are shown in the illustration.
OFF:
With the fuel cock knob in this position, fuel
does not flow. Always turn the fuel cock knob
to this position when the engine is not running.
ON:
With the fuel cock knob in this position, fuel
flows to the carburetors. Turn the fuel cock
knob to this position when starting the engine
and operating the watercraft.
RES:
This indicates reserve. With the fuel cock
knob in this position, the fuel reserve is made
available. Turn the fuel cock knob to this posi-
tion if you run out of fuel while operating the
watercraft. When this occurs, refuel as soon
as possible and be sure to turn the fuel cock
knob back to “ON”!
