Do not attempt to modify this watercraft!
Modifications to your watercraft may
reduce safety and reliability, and render
the watercraft unsafe or illegal for use.

Attach the engine shut-off cord (lanyard)
to wrist and keep it free from the handle-
bars so that the engine stops if the opera-
tor falls off. After riding, remove the
engine shut-off cord from the watercraft to
avoid accidental starting or unauthorized
use by children or others.

Scan carefully for swimmers and stay
away from swimming areas. Swimmers
are hard to see and you could acciden-
tally hit someone 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 you maneuver more quickly than other
boaters expect, you risk a collision.

Maintain a safe distance from other boats
or watercraft, and also watch for boats’ ski
ropes or fishing lines. Obey the “Safe
boating rules,” and be sure to check
behind you before making a turn. (See
Safe boating rules on page 1-20.)

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 sig-
nal other boats.

Visual distress signals
It is recommended that an authority-
approved pyrotechnic device be stored in
a waterproof container on your watercraft.
A mirror can also be used as an emer-
gency signal. Contact your Yamaha
dealer for more information.

Watch
A watch is helpful so you will know how
long you have been operating.

Towline
A towline can be used to tow a disabled
watercraft in an emergency.

Cooling water pilot outlet
This watercraft is equipped with a cooling
water pilot outlet.
When the engine is running, cooling
water is circulated in the engine, and then it
is discharged from the pilot outlet.
To check for proper operation of the cool-
ing system, check that water is being dis-
charged from the pilot outlet. If water is not
being discharged from the outlet, cooling
water may not be circulating in the engine.
When this occurs, stop the engine and
check for the cause. (See pages 2-22 and
5-3 for more information.)
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.

onds.
@
Hour meter
The hour meter is provided to make it
easy to follow the maintenance schedule.
The meter shows the hours of engine
operation that have elapsed since the water-
craft was new.
Vo l t m e t e r
The voltmeter is provided to display the
voltage of the battery.
When the battery voltage is normal, the
voltmeter 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,
beach the watercraft and, if necessary, have
a Yamaha dealer check the charging system
and the battery.
EJU20760
Check engine warning indicator
If a sensor malfunction or a short circuit is
detected, the warning light and the check
engine warning indicator begin to blink and
the buzzer sounds intermittently.
If this occurs, reduce the engine speed,
beach the watercraft, and have a Yamaha
dealer check the engine.

Fuel warning indicator
If the fuel remaining in the tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the
lowest two fuel level segments, the fuel
warning indicator, and the warning light all
begin to blink. The buzzer also starts sound-
ing intermittently.
The warning signals will be cleared when
the engine is restarted after refilling.
EJU20782
Oil pressure warning indicator
If the oil pressure does not rise to specifi-
cation, the warning 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,
beach the watercraft, and then check the
engine oil level. (See page 3-7 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 the select button 1 on the multifunc-
tion meter to stop the buzzer.

EJU21182
Engine overheat warning indicator
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the warn-
ing light and the overheat warning indicator
blink, and then come on. The buzzer also
begins to sound intermittently, and then it
sounds continuously. After the light and indi-
cator start to blink and the buzzer sounds,
the engine speed is limited to help prevent
damage.
If this occurs, immediately reduce the
engine speed, beach the watercraft, and
then check for water discharge at the port
(left) cooling water pilot outlet. If there is no
discharge of water, check the intake grate
and impeller for clogging.
WARNING@ Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
@
CAUTION:@ If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe
engine damage.
@
NOTE:@ Press the select button 1 on the multifunc-
tion meter to stop the buzzer.
