Safety information
14

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 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 some-
one 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 19.)
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.

squeezed. (See page 33 for Yamaha Security
System lock and unlock mode selection pro-
cedures.)
EJU31210Throttle lever
Squeeze the throttle lever to increase engine
speed.
Release the throttle lever to decrease engine
speed or to return it to the idle position.
EJU31240Cooling water pilot outlets
This watercraft is equipped with cooling water
pilot outlets.
When the engine is running, cooling water is
circulated in the engine, and then it is dis-
charged from the pilot outlets.
To check for proper operation of the cooling
system, check that water is being discharged
from the port (left) pilot outlet. If water is not
being discharged from this outlet, cooling wa-
ter may not be circulating in the engine. Whenthis occurs, stop the engine and check for the
cause. (See pages 40 and 94 for more infor-
mation.)
NOTE:

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.

Water discharge may not be constant at the
starboard (right) pilot outlet, however, if it is
constant at the port (left) pilot outlet, the
cooling system is operating normally.
EJU31260Steering system
Your watercraft can be steered by turning the
handlebars in the direction you wish to travel.
When the handlebars are turned, the angle of
the jet thrust nozzle is changed, and the direc-
tion of the watercraft is changed accordingly.
Since the strength of the jet thrust determines1Throttle lever

ponents for help and convenience in operat-
ing the watercraft.
CAUTION:
ECJ00941
Do not run the engine for more than 15
seconds without supplying water or over
6000 r/min on land when checking the op-
eration of the multifunction information
center, otherwise the engine could over-
heat.
NOTE:

When the multifunction information center
starts operating, the analog speedome-
ter/tachometer makes one sweep, all dis-
plays light up for 2 seconds, and then it
starts to operate normally.

The multifunction information center will
continue to operate for 25 seconds after the
engine stops.
EJU34930Analog speedometer/tachometer and indi-
cator lights
This watercraft is equipped with the following
meter and indicator lights.
EJU34941Analog speedometer/tachometer
The analog speedometer/tachometer can be
used as a speedometer or a tachometer.
To switch between the speedometer and the
tachometer functions, push the “Speed/RPM”
button for at least 1 second when the multi-
function information center is operating.
The “SPEED” indicator light comes on when
the analog speedometer is selected. The

the unlock mode of the Yamaha Security Sys-
tem is selected. The watercraft can be ridden
normally when this light is on. (See page 33
for more information.)

Features and functions

The fuel level meter has eight segments
which show the amount of fuel remaining in
the fuel tank.
NOTE:
The fuel level is most accurate when the wa-
tercraft is sitting level on a trailer or in the wa-
ter.
EJU35060Hour meter/voltmeter
NOTE:
To switch the display between the hour meter
and the voltmeter, push the “Volt/Hour” button
for at least 1 second after the meter is dis-
played for more than 10 seconds.
Hour meter
The hour meter is provided to make it easy to
follow the maintenance schedule.The meter shows the hours of engine opera-
tion that have elapsed since the watercraft
was new.
Voltmeter
The voltmeter is provided to display the volt-
age of the battery.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage is less than 8.0 volts,
“LO” is displayed on the voltmeter and if the
voltage is above 18.1 volts, “HI” is displayed
on the voltmeter. If “HI” or “LO” is displayed,
return to shore and, if necessary, have a
Yamaha dealer check the charging system
and the battery.
EJU35072Fuel level warning indicator
If the fuel remaining in the fuel tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the low-
est two fuel level segments, the fuel level
warning indicator, and the “WARNING” indi-
cator light begin to blink. The buzzer also
starts sounding intermittently.
If this occurs, refill the fuel tank as soon as
possible.
The warning signals will be cleared when the
engine is restarted after the fuel tank is re-
filled.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.

EJU35122Oil pressure warning indicator
If the oil pressure does not rise to specifica-
tion, the “WARNING” indicator light and the oil
pressure warning indicator begin to blink, and
the buzzer sounds intermittently. At the same
time, the engine speed is limited to help pre-
vent damage.
If this occurs, reduce the engine speed, return
to shore, and then check the engine oil level.
(See page 53 for engine oil level checking
procedures.) If the oil level is low, add enough
engine oil to raise it to the proper level. If the
oil level is sufficient, have a Yamaha dealer
check the watercraft.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.
EJU36401Engine overheat warning indicator
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the engine
overheat warning system will be activated
and, in some cases, the warning system will
cut the ignition to the engine.
If the “WARNING” indicator light and the en-
gine overheat warning indicator begin to blink,
and the buzzer sounds intermittently, immedi-ately reduce the engine speed and return to
shore.
If the “WARNING” indicator light and the en-
gine overheat warning indicator come on, and
the buzzer sounds continuously, the warning
system will cut the ignition. The engine cannot
be started until it cools down, so it may be
necessary to have the watercraft towed back
to the shore. (See “Towing the watercraft” on
page 97 for towing procedures.)
After the engine cools down, start the engine,
and then check for water discharge at the port
(left) cooling water pilot outlet while the engine
is running. If there is no discharge of water,
shut the engine off, and then check the intake
grate and impeller for clogging.
WARNING
EWJ00050
Before attempting to remove weeds or de-
bris from the intake grate or impeller, shut
the engine off and remove the clip from the
