EJU36270Remote control transmitter
The lock and unlock modes of the Yamaha

mote control transmitter. (See “Yamaha Se-
curity System ” on page 33 for information on
using the remote control transmitter.)
CAUTION:
ECJ00930
The lock and unlock modes of the Yamaha
Security System can only be selected us-
ing the remote control transmitter. Ob-serve the following precautions to protect
your remote control transmitter:

Store the remote control transmitter
carefully so it will not be lost. When op-
erating the watercraft, use the transmit-
ter holder in the watertight
compartment. If you accidentally lose
your remote control transmitter, contact
a Yamaha dealer.

While the remote control transmitter has
been designed for use in wet environ-
ments, it should not be operated under-
water 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 transmit-
ter, 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 properly,
contact a Yamaha dealer. Do not attempt
to replace the battery yourself.

Insert the clip, on the end of the engine shut-
off cord, under the engine shut-off switch

System lock and unlock mode selection pro-
cedures.)
EJU31210Throttle lever
Squeeze the throttle lever to increase engine
speed.
Release the throttle lever to decrease engine
speed or to return it to the idle position.
EJU31240Cooling water pilot outlets
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 dis-
charged from the pilot outlets.
To check for proper operation of the cooling
system, check that water is being discharged
from the port (left) pilot outlet. If water is not
being discharged from this outlet, cooling wa-
ter may not be circulating in the engine. Whenthis occurs, stop the engine and check for the
cause. (See pages 40 and 94 for more infor-
mation.)
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.
EJU31260Steering system
Your watercraft can be steered by turning the
handlebars in the direction you wish to travel.
When the handlebars are turned, the angle of
the jet thrust nozzle is changed, and the direc-
tion of the watercraft is changed accordingly.

EJU36290Yamaha Security System
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The engine cannot be started if the
security system is in the lock mode. The en-
gine can only be started in the unlock mode.
This watercraft is equipped with a remote con-
trol transmitter that is used to select the lock
and unlock modes of the security system.
Since the watercraft is programmed to recog-
nize the internal code from this transmitter
only, the security system mode can only be
changed with this transmitter.
If you lose the remote control transmitter or it
does not operate properly, contact a Yamaha
dealer.
