EJU36851
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 color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.
Do not touch the hot muffler or engine dur-
ing or immediately after engine operation;
they can cause serious burns.
EJU30921
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 is equipped with the Yamaha
Engine Management System (YEMS) that
includes an off-throttle steering (OTS) sys-
tem. 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 sharp-
ly if you apply throttle while turning the han-
dlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the water-
craft will no longer turn in response to han-
dlebar input until you apply throttle again or
you reach trolling speed.
Practice turning in an open area without
obstacles until you have a good feel for this
maneuver.
This watercraft is water-jet propelled. The
jet pump is directly connected to the en-
gine. This means that jet thrust will produce
some movement whenever the engine is
running. There is no “neutral” position. You
are in either “forward” or “reverse”, de-
pending 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 broken
legs, ankles, and other bones. You could
also damage the shift mechanism.

EJU31385Yamaha Security System
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The lock and unlock modes of the
security system can be selected by operating
the remote control transmitter that is included
with this watercraft. The engine cannot be
started if the lock mode of the security sys-
tem is selected. The engine can only be start-
ed if the unlock mode is selected. (See page
25 for information on the remote control
transmitter.)
TIP:
The Yamaha Security System settings can
only be selected while the engine is stopped.
EJU37413Yamaha Security System settingsThe Yamaha Security System settings will be
confirmed by the number of beeps when the
remote control transmitter is operated, and
by the “UNLOCK” indicator light of the dual
analog meter unit. (See page 35 for informa-
tion on the dual analog meter unit.)
TIP:
The beeper sounds two times for the nor-
mal operation mode or three times for the
Low RPM Mode. (See page 33 for Low
RPM Mode activation procedures.)
If the remote control transmitter is operated
while the dual analog meter unit is in the
standby state, the unit will perform the ini- tial operation, and then the setting is se-
lected.
To select the lock mode:
Push the lock button on the remote control
transmitter briefly. The beeper sounds once
and the “UNLOCK” indicator light blinks
once, then goes off. This indicates the lock
mode is selected.
To select the unlock mode:
Push the “L-Mode” (unlock) button on the re-
mote control transmitter briefly. The beeper
sounds two or three times and the “UN-
LOCK” indicator light blinks two or three
times, then comes on. This indicates the un-
lock mode is selected.

EJU31153Engine stop switch “ ”
The engine stop switch (red button) stops the
engine when the switch is pushed.
EJU31164Engine shut-off switch “ ”
The engine shut-off switch automatically
stops the engine when the clip, on the end of
the engine shut-off cord (lanyard), is removed
from the switch, such as if the operator falls
off the watercraft.
Insert the clip under the engine shut-off
switch before starting the engine.
When the engine is not running, remove the
clip from the engine shut-off switch to pre-vent accidental starting or unauthorized op-
eration by children or others.

NOTICE
ECJ01311
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
The start switch (green button) starts the en-
gine when the switch is pushed.
Release the start switch as soon as the en-
gine starts to run. If the engine does not start
in 5 seconds, release the start switch, wait 15
seconds, and then try again.
NOTICE: Never
push the start switch while the engine is
running. Do not operate the start switch
for more than 5 seconds, otherwise the
battery will be discharged and the engine

TIP:
It will take about 60 seconds for the water
to reach the outlets after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.
If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under thewater separator. (2) Gradually loosen the drain screw to drain
the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth.
(3) Securely tighten the drain screw until it stops.

Watercraft operation functions
EJU37183Reverse system
WARNING
EWJ01231
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.
Make sure that there are no obstacles or
people behind you before shifting into
reverse.
Do not touch the reverse gate while the
shift lever is being operated, otherwise
you could be pinched.
When the shift lever is moved to the reverse
position, the reverse gate lowers and deflects
the water jet being discharged from the jet
thrust nozzle. This allows the watercraft to
move in reverse.
To shift into reverse:
(1) Release the throttle lever and let the en-gine speed return to idle.
(2) Pull the shift lever rearward until it stops in the reverse position. The reverse gate will lower and the watercraft will start
moving in reverse at trolling speed.
TIP:
This model is equipped with a function which
limits the engine speed in reverse.
To shift into forward:
(1) Release the throttle lever and let the en-
gine speed return to idle.
(2) Push the shift lever forward until it stops in the forward position. The reverse gate
will rise and the watercraft will start mov-
ing forward at trolling speed.
