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 40 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-

Squeeze the throttle lever to increase engine
speed.
Release the throttle lever to decrease engine
speed or to return it to the idle position.
EJU35971Cooling water pilot outlet
This watercraft is equipped with a cooling wa-
ter pilot outlet.
When the engine is running, cooling water is
circulated in the engine, and then it is dis-
charged from the pilot outlet.
To check for proper operation of the cooling
system, check that water is being discharged
from the pilot outlet. If water is not being dis-
charged from the outlet, cooling water may
not be circulating in the engine. When this oc-
curs, stop the engine and check for the cause.
(See pages 33 and 78 for more information.)
TIP:
If the cooling water passages are dry, it will
take about 60 seconds for the water to
reach the outlet after the engine is started.
Water discharge may not be constant at
idle, therefore, open the throttle a little to
check that water discharges properly.

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,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
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, turn off the engine. Do
not stand or sit on the watercraft. Never
refuel while smoking, or while in the vicin-
ity of sparks, open flames, or other sourc-
es of ignition.
(2) Place the watercraft in a well-ventilated
area and in a horizontal position.
(3) Remove the seat, and then check the fuel
level. (See page 23 for seat removal and
installation procedures.)
(4) Remove the fuel tank filler cap, and then
slowly add fuel to the fuel tank. Stop filling
when the fuel level reaches approximate-
ly 50 mm (2 in) from the top of the fuel
tank. Do not overfill the fuel tank. Be-
cause fuel expands when it heats up,
heat from the engine or the sun can
cause fuel to spill out of the fuel tank. Do
not leave the watercraft with a full tank in
direct sunlight.
Recommended fuel:
Regular unleaded gasoline with a mini-
mum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)

(5) Wipe up any spilled fuel immediately.
(6) Install the fuel tank filler cap. Make sure
that the fuel tank filler cap is securely
closed before operating the watercraft.
(7) Install the seat. Make sure that the seat is
securely installed before operating the
watercraft.
EJU31891Engine oil
NOTICE
ECJ00281
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
Make sure that the engine oil is at the speci-
fied level. Add oil as necessary. (See page 42for engine oil level checking procedures.) Use
a combination of the recommended SAE and
API engine oil classifications shown in the
