in response to handlebar input until you apply
throttle again or you reach trolling speed.
EJU35974Cooling water pilot outlet
When the engine is running, some of the cool-
ing water that is circulated in the engine is dis-
charged from the cooling water pilot outlet.
There is a cooling water pilot outlet on the port
(left) side of the watercraft. To check for prop-
er operation of the cooling system, make sure
that water is being discharged from the cool-
ing water pilot outlet. If water is not being dis-
charged from the outlet, stop the engine and
check the jet intake for clogging. (See page
84 for information on the jet intake.)
TIP:
●It will take about 60 seconds for the water to
reach the outlet after the engine is started.
●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.
EJU40322Water 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.

cator light blink, and the buzzer sounds inter-
mittently.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 44
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is restart-
ed.
TIP:
Push the select button on the multifunction in-
formation center to stop the buzzer.
EJU31626Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator and the “WARN-
ING” indicator light blink, and the buzzer
sounds intermittently. At the same time, the
maximum engine speed is limited.
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 45 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
Push the select button on the multifunction in-
formation center to stop the buzzer.
EJU31609Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. Then, the en-
gine overheat warning indicator and the
“WARNING” indicator light stop blinking and
remain on, and the buzzer sounds continu-
ously. At the same time, the maximum engine
speed is limited.
If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is be-
ing discharged from the cooling water pilot
outlet while the engine is running. If there is no
discharge of water, stop the engine, and then
check the jet intake for clogging. (See page
84 for information on the jet intake.) NOTICE:
If you cannot locate and correct the cause
of the overheating, consult a Yamaha deal-
er. Continuing to operate at higher speeds

(6) Stop filling when the fuel level reaches
approximately 50 mm (2 in) from the top
of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it heats
up, heat from the engine or the sun can
cause fuel to spill out of the fuel tank. Do
not leave the watercraft with a full tank in
direct sunlight.
(7) Wipe up any spilled fuel immediately with
a dry cloth.
(8) Securely install the fuel filler cap by tight-
ening it until it clicks.
(9) Securely install the seat in its original po-
sition.

Engine oil requirements EJU41542Engine oil
NOTICE
ECJ00281
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
Checking the engine oil level
WARNING
EWJ00340
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ00391
●Do not run the engine with too much or
not enough oil in the oil tank, otherwise
the engine could be damaged.
●Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
TIP:
●When checking the engine oil level on land,
the engine must be running while water is
being supplied to the cooling water passag-
es. (See “Flushing the cooling water pas-
seges” on page 71 for information on
supplying water.)
●When checking the engine oil level on wa-
ter, moor the watercraft so that it will not drift
away. Fuel tank capacity:
60 L (15.9 US gal, 13.2 Imp.gal)
