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 100 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.1Cooling water pilot outlet (port [left] side)

EJU43154Shift 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 reverse gate 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

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 reverse
gate will rise completely, the engine
speed will increase, the watercraft will
start moving forward, and the “F” (for-
ward) shift indicator will be displayed.
