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 your wrist and keep it free from the
handlebars so that the engine stops if the
operator 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 if you maneuver more quickly than
other boaters expect, 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 before making a turn. (See
Safe boating rules on page 1-20.)
EJU01382
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.

Start switch
Push the start switch 1 (green button) to
start the engine.
NOTE:@ The engine will not start when the clip is
removed from the engine shut-off switch or if
the throttle lever is squeezed.
EJU01784
Cooling water pilot outlet
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 discharged from the pilot outlets.
To check for proper operation of the cool-
ing system, check that water is being dis-
charged from the port (left) pilot outlet. If
water is not being discharged from this out-
let, cooling water may not be circulating in
the engine. When this occurs, stop the
engine and check for the cause. (See pages
2-24 and 5-3 for further instructions.)
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.

Fuel meter
The fuel meter is provided for convenient
fuel level checking while riding. The fuel
meter has eight segments which show the
amount of fuel remaining in the fuel tank.

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,
return to shore and, if necessary, have a
Yamaha dealer check the charging system
and the battery.

Check engine warning indicator
If a sensor malfunction or a short circuit is
detected, the “WARNING” indicator light and
the check engine warning indicator begin to
blink and the buzzer sounds intermittently.

lowest two fuel level segments, the fuel
warning indicator, and the “WARNING” indi-
cator light all begin to blink. The buzzer also
starts sounding intermittently.
The warning signals will be cleared when
the engine is restarted after refilling.

Oil pressure warning indicator
If the oil pressure does not rise to specifi-
cation, 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 lim-
ited to help prevent damage.
If this occurs, reduce the engine speed,
return to shore, 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 any button on the multifunction meter
to stop the buzzer.

Engine overheat warning indicator
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the
“WARNING” indicator light and the overheat
warning indicator blink, and then come on.
The buzzer also begins to sound intermit-
tently, and then it sounds continuously. After
the light and indicator start to blink and the
buzzer sounds, the engine speed is limited
to help prevent damage.
If this occurs, immediately reduce the
engine speed, return to shore, and then
check for water discharge at the port (left)
cooling water pilot outlet. If there is no dis-
charge 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 any button on the multifunction meter
to stop the buzzer.
