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.

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 98 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 57 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.

EJU44252Stern drain plug checks
Loosen the stern drain plugs and remove
them, and then make sure that the plugs and
O-rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs. NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads and the O-
rings on the plugs to remove any foreign
materials, such as dirt or sand. Otherwise,
the stern drain plugs could be damaged,
allowing water to enter the engine com-
partment. Check the O-rings on the stern
drain plugs and make sure that the plugs
are tightened securely before launching
the watercraft. Otherwise, water may
flood the engine compartment and cause
the watercraft to submerge.
[ECJ00364]
Securely install the stern drain plugs by tight-
ening them until they stop.
EJU41441Hood check
Push down on the rear of the hood and make
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 72 for information on launching the watercraft.)
(2) Perform the checks and make sure that there are no malfunctioning items or oth-
er problems.
EJU41811Cooling water pilot outlet check
Make sure that water is discharged from the
port (left) cooling water pilot outlet while the
engine is running. (See page 27 for informa-
tion on the cooling water pilot outlets.)

EJU40242After removing the watercraft from
the water
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.
After operating and removing the watercraft
from the water, promptly discharge the re-
maining water from the cooling water pas-
sages.
To discharge water from the cooling wa-
ter passages:
(1) Make sure that the area around the wa- tercraft is clear, and then start the en-
gine.
(2) Discharge the remaining water out of the cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(3) Stop the engine.
