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 62 before operat-
ing the watercraft.
●The operator and passengers should al-
ways keep their feet on the floor of the foot-
well when the watercraft is in motion. Liftingyour feet increases the chances of losing
your balance, or hitting objects outside the
watercraft with your feet. Do not give a ride
to children if their feet cannot reach the floor
of the footwell.
●The passengers should hold on firmly, ei-
ther to the person in front of them or to the
handgrip provided.
●Never allow a passenger to ride in front of
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 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-

in response to handlebar input until you apply
throttle again or you reach trolling speed.
EJU31293Adjustable tilt steering system
The position of the handlebars can be adjust-
ed back and forth by operating the tilt lever.
To adjust the handlebar position:
(1) Pull the tilt lever up to disengage the han-
dlebar lock, and then move the handle-
bars back or forth to the desired position.
WARNING! Never pull the tilt lever dur-
ing operation, otherwise the handle-
bars may suddenly change position,
which may lead to an accident.
[EWJ00041]
(2) Make sure that the tilt lever returns to its
original position and that the handlebars
are securely locked in place.
EJU35974Cooling water pilot outlet
When the engine is running, some of the cool-
ing water that is circulated in the engine is dis-
charged from the cooling water pilot outlet.
There is a cooling water pilot outlet on the port
(left) side of the watercraft. To check for prop-
er operation of the cooling system, make sure
that water is being discharged from the cool-
ing water pilot outlet. If water is not being dis-
charged from the outlet, stop the engine and
check the jet intake for clogging. (See page
99 for information on the jet intake.)
TIP:
●It will take about 60 seconds for the water to
reach the outlet after the engine is started.

WARNING
EWJ00282
●Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.
●Gasoline is poisonous and can cause in-
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,

NOTICE
ECJ00321
●Do not use leaded gasoline. Leaded gas-
oline can seriously damage the engine.
●Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and thefuel meets the minimum octane ratings. E-85
is a fuel blend containing 85% ethanol and
therefore must not be used in this watercraft.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or en-
gine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.
To fill the fuel tank:
(1) Before refueling, stop the engine. Do not
stand or sit on the watercraft. Never refu-
el while smoking, or while in the vicinity of
sparks, open flames, or other sources of
ignition.
(2) Place the watercraft in a well-ventilated
area and in a horizontal position.
(3) Remove the seats, and then check the
fuel level. (See page 46 for seat removal
and installation procedures.)
(4) Pull the hood latch rearward, and then lift
up the rear of the hood.
