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
66 for information on the jet intake.)
TIP:
●It will take about 20 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.
EJU31664Engine overheat warning system
If the engine temperature rises significantly,
the engine overheat warning system will acti-
vate and the engine speed will be limited to
about 3400 r/min to help prevent damage.

If the engine overheat warning system is acti-
vated, immediately reduce the engine speed,
return to shore, and then make sure that wa-
ter is being 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 66 for information on the jet intake.)
NOTICE: If you cannot locate and correct
the cause of the overheating, consult a
Yamaha dealer. Continuing to operate at higher speeds could result in severe en-
gine damage.

WARNING
EWJ00282
●Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.
●Gasoline is poisonous and can cause in-
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
NOTICE
ECJ00321
●Do not use leaded gasoline. Leaded gas-
oline can seriously damage the engine.
●Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol. Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the
fuel meets the minimum octane ratings. E-85
is a fuel blend containing 85% ethanol and
therefore must not be used in this watercraft.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or en-
gine performance problems.
Yamaha does not recommend gasohol con- taining methanol because it can cause fuel
system damage and engine performance
problems.
EJU318722-stroke engine oil
If YAMALUBE 2-W engine oil is not available,
another 2-stroke engine oil with an NMMA-
certified TC-W3 rating may be used.
EJU31902Mixing fuel and oil
NOTICE
ECJ00331
Make sure that the gasoline and oil are
thoroughly mixed in the correct ratio, oth-
erwise severe engine damage could re-
sult.
To mix gasoline and engine oil:
(1) Pour 2-stroke engine oil into a clean con- tainer, and then add gasoline.
Recommended fuel: Regular unleaded gasoline with a
minimum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)
Recommended engine oil:YAMALUBE 2-W or TC-W3 outboard
motor oil or equivalent
Fuel-to-oil ratios (gasoline to oil) Break-in period (first two tankfuls): 25:1
After break-in: 50 :1

Transporting
WARNING
EWJ00750
Always turn the fuel cock knob to “OFF”
when transporting the watercraft, other-
wise fuel could leak out into the engine or
engine compartment, which would create
a fire hazard.
When transporting the watercraft on a trailer,
secure the bow rope hole and stern of the wa-
tercraft to the trailer with ropes or tie downs.
Use a rubber shock cord to secure the steer-
ing pole to the watercraft. NOTICE: Do not
secure the steering pole with ropes or tie
downs and do not secure it to the trailer.
Also, do not transport the watercraft with
the steering pole up. Otherwise, the steer-
ing pole could be damaged. Wrap the
ropes or tie downs with towels or rags where they touch the body of the water-
craft to avoid scratches or damage.
