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 1-17.)
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.

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 2-17 and
5-4 for further instructions.)
NOTE:@ If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlet after the engine is started.
@
EJU01021
Steering system
Your watercraft can be steered by turning
the handlebars 1 the same direction you
wish to travel.
When the handlebars are turned, the
angle of the jet thrust nozzle 2 is changed,
and the direction of the watercraft is
changed accordingly. Since the strength of
the jet thrust determines the speed and
direction of a turn, the throttle must always
be open when attempting a turn, except at
trolling speed.

Engine overheat warning
system
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the warn-
ing light, the indicator for the water tempera-
ture symbol, and “W. T E M P” display begin to
blink, the buzzer sounds, and the engine
speed will be limited to about 3,400 r/min.
When this occurs, check for water dis-
charge at the cooling water pilot outlet. If
there is no discharge of water, reduce the
engine speed and beach the watercraft, and
then 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.

ging.

Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment
remove the rear and front seats. (See pages
2-4 and 2-5 for seat removal and installation
procedures.) Allow the engine compartment
to remain open for a few minutes to allow
any fuel vapors to escape. Also, check for
loose electrical connections.
WARNING@ Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or a loose electrical connection.

EJU01318
Fuel and oil systems
Check the fuel system for leakage, cracks
or malfunctions before each use. (See page
4-10 for check points and correct proce-
dures.)
1. Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
2. Remove the rear and front seats. (See
pages 2-4 to 2-5 for seat removal and
installation procedures.)
3. Check the fuel and oil levels in the tanks
and replenish if necessary. (See pages
