Hazard information
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.
Hot oil tank, muffler, and engine surfaces
can cause serious burns. Do not touch
the oil tank, muffler, or engine immedi-
ately after turning the engine off.

Watercraft characteristics
Jet thrust turns the watercraft. Releasing
the throttle lever completely produces
only minimum thrust. If you are traveling
at speeds above trolling, you will have
rapidly decreasing ability to steer without
throttle. This model has the Yamaha
Engine Management System (YEMS)
that includes an Off-Throttle Steering
(OTS) system. It will activate at planing
speeds should you attempt to steer the
watercraft after releasing the throttle lever.
The OTS system assists in turning by
continuing to supply some thrust while the
watercraft is decelerating, but you can
turn more sharply if you apply throttle
while turning the handlebars. The OTS
system does not function below planing
speeds or when the engine is off. Once
the engine slows down, the watercraft will
no longer turn in response to handlebar
input until you apply throttle again or you
reach trolling speed. Practice turning in
an open area without obstructions until
you have a good feel for this maneuver.
This watercraft is 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. You could also
damage the shift mechanism.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and bro-
ken legs, ankles, and other bones.

Remote control transmitter
The Yamaha Security System and low-
RPM mode settings are selected using the
remote control transmitter. (See “Yamaha
Security System/Low-RPM mode” on page
2-20 for information on using the remote
control transmitter.)
CAUTION:@ The Yamaha Security System and low-
RPM mode settings can only be selected
using the remote control transmitter.
Observe the following precautions to
protect your remote control transmitter:
Store the remote control transmitter
carefully so it will not be lost. When
operating the watercraft, use the trans-
mitter holder 1 in the watertight com-
partment. If you accidentally lose your
remote control transmitter, contact a
Yamaha dealer.
While the remote control transmitter
has been designed for use in wet envi-
ronments, it should not be operated
underwater or submerged for an
extended length of time. If it gets wet,
dry it with a soft, dry cloth.
Keep the remote control transmitter
away from high temperatures and do
not place it in direct sunlight.
Do not drop the remote control trans-
mitter, subject it to strong shocks, or
place any heavy items on it.
Use a soft, dry cloth to clean the trans-
mitter. Do not use detergent, alcohol,
or other chemicals.
If the remote control transmitter needs
a new battery or is not operating prop-
erly, contact a Yamaha dealer. Do not
attempt to replace the battery yourself.

Starting the engine
WARNING@ Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monox-
ide, a colorless, odorless gas that may
cause loss of consciousness and death
within a short time. Always operate the
watercraft in an open area.
@
1. If the lock mode of the Yamaha Security
System is selected, use the remote con-
trol transmitter to select the unlock
mode. (See page 2-21 for Yamaha Secu-
rity System and low-RPM mode selec-
tion procedures.)
2. Launch the watercraft in water free from
weeds and debris and at least 60 cm
(2 ft) deep.
WARNING@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged
object, which could result in injury.
@
CAUTION:@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise pebbles or
sand could be sucked into the jet intake,
causing impeller damage or engine over-
heating.

Towing the watercraft
If the watercraft becomes inoperative in
the water, it can be towed to shore.
If the watercraft must be towed in an
emergency using a towline, the operator
should ride the watercraft, holding onto the
handlebars.
CAUTION:@ Tow the watercraft at 5 mph (8 km/h) or
less, otherwise water could enter the
engine through the exhaust passages
or through the air intake and flood the
engine compartment if it is towed too
fast.
Tow the watercraft using the bow
eye1 only.
The bow must be kept up out of the
water during towing to prevent water
from entering the engine compart-
ment.
@
WARNING@ The watercraft should only be towed in
an emergency.
The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down. A
good rule of thumb is a towline that is
three times the combined length of the
towing boat and the watercraft.
The operator of the towing boat must
keep speed to a minimum and avoid
traffic or obstacles which could be a
hazard to the rider on the watercraft.
