Control function operation
26
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.
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.

Control function operation
27
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 97 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 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.

shore, and have a Yamaha dealer check the
engine.
TIP
Push the “OK” button of the touchpad control
to display a description of the warning in the
center display.
Engine overheat warning “ ”
If the engine temperature rises
significantly, “ ” and “ ” are shown in the
warning bar, and the buzzer sounds continu-
ously.
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 port (left) cooling
water pilot outlet while the engine is running.
If there is no discharge of water, stop the en-
gine, and then check the jet intake for clog-
ging. (See page 97 for information on the jet
intake.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-
ate at higher speeds could result in severe
engine damage.
[ECJ00042]
TIP
While the engine overheat warning is acti-
vated, the maximum engine speed is limit-
ed.
Push the “OK” button of the touchpad con-
trol to display a description of the warning
in the center display.
Oil pressure warning “ ”
If the oil pressure drops significantly, “ ”
and “ ” are shown in the warning bar, and
the buzzer sounds intermittently.
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 56 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP
While the oil pressure warning is activated,
the maximum engine speed is limited.
Push the “OK” button of the touchpad con-
trol to display a description of the warning
in the center display.
Other warnings (communication errors,
exceeding the maintenance intervals, and
so on) “ ”
If any other malfunction is detected or if the
engine has been operated for more than 50
hours since the last maintenance, the warn-
ing bar is shown instead of the tachometer
value display, “ ” is shown, and the buzz-
er sounds intermittently.

To ensure safety and reliability, pre-operation checks should be made each time the water-
craft is used.
Hood Check that the hood is securely closed. 68
Front and rear seats Check that the seats are securely installed. 47

sure that it is securely closed.
EJU40147Post-launch checks
Perform the post-launch checks in the pre-
operation checklist while the watercraft is in
the water and the engine is running.
To perform the post-launch checks:
(1) Launch the watercraft. (See page 71 forinformation on launching the watercraft.)
(2) Perform the checks and make sure that there are no malfunctioning items or oth-
er problems.
EJU40553Cooling water pilot outlet check
Make sure that water is discharged from the
cooling water pilot outlet while the engine is
running. (See page 26 for information on the
cooling water pilot outlet.)
EJU45260Multifunction information center check
Make sure that the multifunction information
center operates properly. (See page 37 for in-
formation on proper operation of the multi-
function information center.)
EJU43393Shift system check
Operate the throttle lever and RiDE lever, and
check that the watercraft moves or does not
move according to the displayed shift indica-
tor. (See page 28 for shift system operation
procedures.) WARNING! To avoid colli-
sions, operate at safe speeds and keep a
safe distance away from people, objects,
and other watercraft.
