Watercraft glossary
Trolling speed
“Trolling” is the lowest maneuvering speed. You are applying little or no throttle. The watercraft
is down in the water, and there is no wake.
Sub-planing speed
“Sub-planing” is a medium speed. The bow of the watercraft is slightly up from the water sur-
face, but you are still traveling through the water. There is a wake.
Planing speed
“Planing” is a faster speed. The watercraft is more level and is skimming on top of the water.
There is a wake.
Bow
The front end of the watercraft.
Stern

EJU31384Yamaha 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 system
is selected. The engine can only be started if
the unlock mode is selected. (See page 26 for
information on the remote control transmitter.)
TIP:
The Yamaha Security System settings can
only be selected while the engine is stopped.
EJU36775Yamaha Security System settings
The 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 multifunc-
tion information center. (See page 39 for infor-
mation on the multifunction information
center.)
TIP:

The beeper sounds two times for the nor-
mal operation mode or three times for the
Low RPM Mode. (See page 34 for Low
RPM Mode activation procedures.)

If the remote control transmitter is operated
while the multifunction information center is
in the standby state, the center will performthe initial operation, and then the setting is
selected.
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 “UNLOCK”
indicator light blinks two or three times, then
comes on. This indicates the unlock mode is
selected.

EJU31152Engine stop switch“”
The engine stop switch (red button) stops the
engine when the switch is pushed.
EJU31163Engine 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 preventaccidental starting or unauthorized operation
by children or others.

NOTICE
ECJ01310
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

will not start. Also, the starter motor could
be damaged.
[ECJ01040]
The engine will not start under any of the fol-
lowing conditions:

Lock mode of the Yamaha Security System
has been selected. (See page 27 for
Yamaha Security System setting proce-
dures.)

Clip is removed from the engine shut-off
switch.

Throttle lever is squeezed.EJU31211Throttle lever
The throttle lever increases the engine speed
when the lever is squeezed.
The throttle lever returns automatically to its
fully closed (idle) position when released.
EJU31261Steering system
By turning the handlebars in the direction you
wish to travel, the angle of the jet thrust nozzle
is changed, and the direction of the watercraft
is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn, ex-
cept at trolling speed.
This model is equipped with the Yamaha En-
gine Management System (YEMS) that in-
cludes 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 sys-
tem 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.
EJU31293Adjustable tilt steering system
The position of the handlebars can be adjust-
ed back and forth by operating the tilt lever.
To adjust the handlebar position:
(1) Pull the tilt lever up to disengage the han-
dlebar lock, and then move the handle-
bars back or forth to the desired position.
WARNING! Never pull the tilt lever dur-
ing operation, otherwise the handle-
bars may suddenly change position,
which may lead to an accident.
[EWJ00041]
(2) Make sure that the tilt lever returns to its
original position and that the handlebars
are securely locked in place.
EJU41800Cooling water pilot outlets
When the engine is running, some of the cool-
ing water that is circulated in the engine is dis-
charged from the cooling water pilot outlets.
There are cooling water pilot outlets on the
port (left) and starboard (right) sides of the
watercraft. To check for proper operation of
the cooling system, make sure that water is
being discharged from the port (left) pilot out-
let. If water is not being discharged from the
outlet, stop the engine and check the jet in-
take for clogging. (See page 97 for informa-
tion on the jet intake.)
TIP:

It will take about 60 seconds for the water to
reach the outlets after the engine is started.

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.
EJU40322Water 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 the
water 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 thewatercraft, be sure to wipe it up with a dry
cloth.
(3) Securely tighten the drain screw until it
stops.
