EJU46112Engine start/stop switch “ / ”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 engine start/stop switch (red button)
starts the engine when the switch is pushed
while the engine is stopped, and stops the
engine when the switch is pushed while the
engine is running.
Release the engine start/stop switch as soon
as the engine starts to run. If the engine does
not start in 5 seconds, release the engine
start/stop switch, wait 15 seconds, and then
try again.
The engine will not start under any of the fol-
lowing conditions:
Lock mode of the Yamaha Security System
has been selected. (See page 24 for
Yamaha Security System setting proce- dures.)
Clip is removed from the engine shut-off
switch.
Throttle lever is squeezed.
Throttle lever is malfunctioning.
RiDE lever is squeezed.
RiDE lever is malfunctioning.
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.

The throttle lever returns automatically to its
fully closed (idle) position when released.
EJU43342RiDE lever
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.
EJU31262Steering system
By turning the handlebars in the direction you
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.
EJU31294Adjustable 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.

(2) Make sure that the tilt lever returns to itsoriginal position and that the handlebars
are securely locked in place.
EJU41801Cooling water pilot outlets
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged 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 98 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 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.

EJU43155Shift system EWJ01773
Make sure that there are no obstacles or
people behind you before shifting into
reverse.
Do not touch the reverse gate while the
RiDE lever is being operated, otherwise
you could be pinched.
If the RiDE lever and throttle lever are
being operated at the same time, do not
release only the RiDE lever. Otherwise,
the watercraft could accelerate more
quickly than expected, which may lead
to an accident.
The RiDE lever and throttle lever can be oper-
ated to change the forward or rearward
movement of the watercraft only when the
engine is running. When the RiDE lever is
squeezed, the reverse gate lowers and de-
flects the water jet being discharged from the
jet thrust nozzle so that the watercraft moves
in reverse or is in neutral. When the throttle le-
ver is squeezed, the reverse gate rises and
the watercraft moves forward.
TIP
This model is equipped with a function
which limits the engine speed in reverse.
When the engine is started, the reverse
gate automatically moves to the neutral po-
sition.
To shift into reverse:
(1) Release the throttle lever.
(2) Squeeze the RiDE lever. The reversegate will lower, the engine speed will in-
crease, the watercraft will start moving in reverse, and the “R” (reverse) shift indi-
cator will be displayed.To shift into neutral from reverse:
Release the RiDE lever. The reverse gate will
automatically return to the neutral position

and the “N” (neutral) shift indicator will be dis-
played.
TIP
Although the neutral position helps keep the
watercraft from moving even when the en-
gine is running, some movement may occur.
To shift into forward:
(1) Release the RiDE lever.
(2) Squeeze the throttle lever. The reversegate will rise completely, the engine
speed will increase, the watercraft will
start moving forward, and the “F” (for-
ward) shift indicator will be displayed.

TIP
If the RiDE lever is squeezed while the throttle
lever is squeezed, the watercraft will slow
down, and once stopped, move in reverse.
To shift into neutral from forward:
(1) Release the throttle lever.
(2) Lightly squeeze and release the RiDE le-ver. The “N” (neutral) shift indicator will
be displayed.
TIP
If the RiDE lever is squeezed continuously,
the reverse gate will move to the reverse po-
sition.
EJU45880Electric trim system
The electric trim system is a function for
changing the vertical angle of the jet thrust
nozzle to change the trim angle and perfor-
mance characteristics of the watercraft.
This function can be used only for forward
operation of the watercraft.
TIP
When the watercraft is moving in reverse or
is in neutral, the jet thrust nozzle will auto-
matically change to the neutral trim setting.
When the watercraft is shifted into forward,
the jet thrust nozzle will automatically
change to the selected trim setting.
While the watercraft is in neutral, the
“TRIM/T.D.E.” switch controls the forward
and reverse operation of the T.D.E. (thrust
direction enhancer). (See page 33 for infor-
mation on the T.D.E.)
The watercraft perfor mance characteristics
according to the trim angle change de-
pending on the operating conditions.

Confirming the trim setting
The trim setting can be confirmed by the trim
setting indicator on the multifunction infor-
mation center.
To change the trim setting:
(1) Shift into forward.
(2) Push the upper side of the “TRIM/T.D.E.”switch to increase the trim setting and
raise the bow, or push the lower side of
the “TRIM/T.D.E.” switch to decrease the
trim setting and lower the bow. The trim
angle can be adjusted in the range of the
trim settings –2 to +2.
Bow-up positions
The bow will go up, causing the trim angle to
increase.
There is less water resistance, therefore,
straight-ahead acceleration is enhanced. Bow-down positions
The bow will go down, causing the trim angle
to decrease.
Vertical movement of the bow will be reduced
and the watercraft will get up on plane more
quickly when accelerating.
