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 95 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.

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

WARNING
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 inreverse, 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 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.
