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 55 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.
EJU37341Telescopic steering system
The position of the handlebars can be adjust-
ed up or down by operating the lock lever.
The handlebars can be adjusted to three po-
sitions.
To adjust the handlebar position:
(1) Pull the lock lever up to disengage the
handlebar lock, and then move the han-
dlebars up or down to the desired posi-
tion. WARNING! Never pull the lock
lever during operation, otherwise the
handlebars may suddenly change po-
sition, which may lead to an accident.
[EWJ01270]
(2) Make sure that the lock lever returns to its
original position and that the handlebars
are securely locked in place.
EJU36743Cooling water pilot outlets
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 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-
lets. If water is not being discharged from
these outlets, stop the engine and check the
jet intake for clogging. (See page 91 for infor-
mation on the jet intake.)
TIP:

It will take about 60 seconds for the water to
reach the outlets after the engine is started.

EJU35024Information display
The information display shows watercraft op-
erating conditions.
EJU37264Hour meter/voltmeter
The hour meter/voltmeter has both an hour
meter function and a voltmeter function. By
switching the meter, it can be used as either
an hour meter or a voltmeter.
TIP:
The hour meter is selected at the Yamaha
factory.Hour meter
The hour meter shows the total number of
hours that the engine has been running since
the watercraft was new.
TIP:
The elapsed time will be kept even if the bat-
tery terminals have been disconnected.
To switch to the hour meter from the voltme-
ter:
Push the “Hour Volt” button for at least 1 sec-
ond. The display switches to the hour meter
from the voltmeter.
Voltmeter
The voltmeter shows the battery voltage.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage has dropped significant-
ly, “LO” is displayed on the voltmeter. If the
battery voltage has risen significantly, “HI” is
displayed. If “LO” or “HI” is displayed, immedi-
ately return to shore and have a Yamaha
dealer service the watercraft.

sounds intermittently. At the same time, the
maximum engine speed is limited.
If the oil pressure warning is activated, imme-
diately reduce the engine speed, return to
shore, and then check the engine oil level.
(See page 50 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
Push the “Hour Volt” button to stop the buzz-
er.
EJU37301Engine overheat warning
If the engine temperature rises significantly,
the “WARNING” indicator light and the engine
overheat warning indicator blink, and the
buzzer sounds intermittently. Then, the
“WARNING” indicator light and the engine
overheat warning indicator stop blinking and
remain on, and the buzzer sounds continu-
ously. After the light and indicator start to blinkand the buzzer sounds, the maximum engine
speed is limited.
If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is be-
ing discharged from the port (left) cooling wa-
ter pilot outlets while the engine is running. If
there is no discharge of water, stop the en-
gine, and then check the jet intake for clog-
ging. (See page 91 for information on the jet
intake.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-
ate at higher speeds could result in severe
engine damage.

If the check engine warning is activated, im-
mediately reduce the engine speed, return to
shore, and have a Yamaha dealer check the
engine.

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, 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 40 for seat removal
and installation procedures.)
(4) Push the hood latch, and then lift up the
rear of the hood.
Recommended fuel:
Regular unleaded gasoline with a
minimum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)
