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 cau-
se choking, severe and permanent neck in-
juries, 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 67 before op-
erating the watercraft.
The operator should grip the handlebars
firmly with both hands and the passengers
should hold on firmly, either to the personin front of them or to the handgrip provid-
ed.
The operator and passengers should al-
ways keep their feet on the floor of the foot-
well when the watercraft is in motion.
Lifting your feet increases the chances of
losing your balance, or hitting objects out-
side the watercraft with your feet. Do not
give a ride to children if their feet cannot
reach the floor of the footwell.
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 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-

ther direction, although some movement
may occur.
To avoid rear-end collisions while operat-
ing the watercraft, check behind you be-
fore using the RiDE lever to slow down or
stop the watercraft. Make sure that there
are no obstacles or people behind you be-
fore shifting into reverse.
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.

(2) Make sure that the tilt lever returns to its
original position and that the handlebars
are securely locked in place.
EJU41801Cooling water pilot outlets
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlets.
There are cooling water pilot outlets on the
port (left) and starboard (right) sides of the
watercraft. To check for proper operation of
the cooling system, make sure that water is
being discharged from the port (left) pilot out-
let. If water is not being discharged from the
outlet, stop the engine and check the jet in-
take for clogging. (See page 103 for informa-
tion on the jet intake.)
TIP:
It will take about 60 seconds for the water
to reach the outlets after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.
If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under the
water separator.
(2) Gradually loosen the drain screw to drain
the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth.
(3) Securely tighten the drain screw until it
stops.1Cooling water pilot outlet (port [left] side)

WARNING
EWJ00283
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,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
NOTICE
ECJ01870
Do not use leaded gasoline. Leaded
gasoline can seriously damage the en-
gine.
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.
Use only gasoline with a minimum pump
octane number of 91 or a minimum re-
search octane number of 95. Low-oc-
tane gasoline can seriously damage the
engine.
Your Yamaha engine has been designed to
use premium unleaded gasoline with a pump
octane number [(R+M)/2] of 91 or higher, or a
research octane number of 95 or higher. Ifknocking (or pinging) occurs, use a gasoline
of a different brand.
TIP:
This mark identifies the recommended fuel
for this watercraft as specified by European
regulation (EN228).
Check that gasoline nozzle has the same
identifier when fueling.
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
the fuel meets the minimum octane ratings.
E-85 is a fuel blend containing 85% ethanol
and therefore must not be used in this water-
craft. All ethanol blends containing more than
10% ethanol can cause fuel system damage
or engine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.Recommended fuel:
Premium unleaded gasoline with a
minimum octane rating of
91
(Pump octane number) = (R + M)/2
95 (Research octane number)

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 49 for seat removal
and installation procedures.)
(4) Pull the hood latch rearward, and then lift
up the rear of the hood.
(5) Loosen the fuel filler cap and remove it.
(6) Slowly add fuel to the fuel tank.(7) Stop filling when the fuel level reaches
approximately 50 mm (2 in) from the top
of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it
heats up, heat from the engine or the sun
can cause fuel to spill out of the fuel tank.
