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.

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

will not start. Also, the starter motor could
be damaged.
[ECJ01041]
The engine will not start under any of the fol-
lowing conditions:
Clip is removed from the engine shut-off
switch.
Throttle lever is squeezed.
Throttle lever is malfunctioning.
EX DELUXE / EX LIMITED: RiDE lever is
squeezed.
EX DELUXE / EX LIMITED: RiDE lever is
malfunctioning.
EJU31212Throttle 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.
EJU43342RiDE lever (EX DELUXE / EX LIMITED)
When the RiDE lever is squeezed, the reverse
gate lowers and the watercraft starts moving
in reverse. If the watercraft is moving forward,
the watercraft gradually slows down until it
stops, and then the watercraft starts moving
in reverse.
When the RiDE lever is released, it automati-
cally returns to its fully closed (idle) position
and the reverse gate moves to the neutral po-
sition.

wish to travel, the angle of the jet thrust noz-

zle is changed, and the direction of the water-
craft 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,
except 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.EJU35975Cooling water pilot outlet
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlet.
There is a cooling water pilot outlet on the
port (left) side of the watercraft. To check for
proper operation of the cooling system, make
sure that water is being discharged from the
cooling water pilot outlet. If water is not being
discharged from the outlet, stop the engine
and check the jet intake for clogging. (See
page 89 for information on the jet intake.)
TIP:
It will take about 60 seconds for the water
to reach the outlet 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.

EJU40522Reverse system (EX SPORT)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.
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.

Multifunction information center
The multifunction information center displays
various watercraft information.
Multifunction information center initial op-
eration
When the multifunction information center is
activated, all of the display segments come
on. After 2 seconds, the warning indicators in
the information display go off, and then the
center starts to operate normally.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 30 sec-
onds after the engine stops, the center will
turn off and enter a standby state. When the
engine is started again, the displays return to
their state before the center turned off, and
then the center starts to operate normally.
EJU35027Information display
The information display shows watercraft op-
erating conditions.
EJU43832Speedometer
The speedometer shows the watercraft
speed against water.
By switching the display units, the speed can
be shown in kilometers per hour “km/h” or
miles per hour “MPH”.
TIP:
“MPH” is selected as the display unit at the
Yamaha factory.

To switch the speedometer display units:
Start the engine, stop the engine, and then
push the engine stop switch 3 times, pushing
the switch for 0.4 seconds or more each time,
before the multifunction information center
turns off. The speedometer display units
change.
To switch the speedometer display units
again, repeat this procedure.

The tachometer shows the engine speed.
TIP:
While the engine is stopped, the battery volt-
age and the total engine hours are displayed
alternately.
EJU43891Shift indicator (EX DELUXE / EX LIMITED)
This indicator shows the reverse gate shift
positions: “F” (forward), “N” (neutral), and “R”
(reverse). (See page 29 for shifting proce-
dures.)

EJU44710Fuel level warning
If the fuel remaining in the fuel tank drops to
about 8 L (2.1 US gal, 1.8 Imp.gal), the lowest
fuel level segment, the fuel level warning indi-
cator, and the “WARNING” indicator light
blink, and the buzzer sounds intermittently for
30 seconds.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 43
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is re-
started.
EJU43720Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator, the check engine
warning indicator, and the “WARNING” indi-
cator light blink, and the buzzer sounds inter-
mittently for 30 seconds. At the same time,
the maximum engine speed is limited.If the oil pressure warning is activated, imme-
diately reduce the engine speed, return to
shore, and then check the engine oil level.
(See page 45 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
EJU43901Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator, the
check engine warning indicator, and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. After 5 sec-
onds, the engine overheat warning indicator
and the “WARNING” indicator light stop
blinking and remain on, and the buzzer
sounds continuously. After 30 seconds, the
buzzer stops. While the engine overheat
warning is activated, the maximum engine
speed is limited.
If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is
being discharged from the cooling water pilot
outlet while the engine is running. If there is
no discharge of water, stop the engine, and
then check the jet intake for clogging. (See
page 89 for information on the jet intake.)
NOTICE: If you cannot locate and correct
the cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
