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 1-18.)
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.

Hazard information
When transporting or storing your water-
craft, always place the fuel cock knob in
the “OFF” position, otherwise gasoline
may overflow from the carburetor.
Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monoxide,
a colorless, odorless gas that may cause
loss of consciousness and death within a
short time. Always operate the watercraft
in an open area.
EJU01209
Watercraft characteristics
Jet thrust turns the watercraft. Releasing
the throttle completely produces only min-
imum thrust. If you are traveling at speeds
above trolling, you will have rapidly
decreasing ability to steer without throttle.
You may still have some turning ability
immediately after releasing the throttle,
but once the engine slows down, the
watercraft will no longer respond to han-
dlebar input until you open the throttle
again or you reach a trolling speed. Prac-
tice turning in an open area without
obstructions until you have a good feel for
this maneuver.
This watercraft are water-jet propelled.
The jet pump is directly connected to the
engine. This means that jet thrust will pro-
duce some movement whenever the
engine is running. There is no “neutral”
position. You are in either “forward” or
“reverse,” depending upon the shift lever
position.
Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or
impact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and bro-
ken legs, ankles, and other bones. You
could also damage the shift mechanism.

Engine stop switch
Push this switch 1 (red button) to stop
the engine normally.
EJU01016
Engine shut-off switch
Insert the clip 1, on the end of the engine
shut-off cord 2, under the engine shut-off
switch 3 (black button). The engine will stop
automatically when the clip is removed from
the switch, such as if the operator falls off
the watercraft.
WARNING@ Always attach the engine shut-off cord
to your wrist and the clip to the engine
shut-off switch BEFORE starting the
engine.
To prevent accidental starting of the
engine or unauthorized use by chil-
dren or others, always remove the clip
from the shut-off switch when the
engine is not running.

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.
