EJU36850
Hazard information

Never start the engine or let it run for any
length of time in an enclosed area. Exhaust
fumes contain carbon monoxide, a color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.

Do not touch the hot muffler or engine dur-
ing or immediately after engine operation;
they can cause serious burns.
EJU30920
Watercraft characteristics

Jet thrust turns the watercraft. Releasing
the throttle lever completely produces only
minimum thrust. If you are traveling at
speeds above trolling, you will have rapidly
decreasing ability to steer without throttle.
This model is equipped with the Yamaha
Engine Management System (YEMS) that
includes an off-throttle steering (OTS) sys-
tem. It will activate at planing speeds should
you attempt to steer the watercraft after re-
leasing the throttle lever. The OTS system
assists in turning by continuing to supply
some thrust while the watercraft is deceler-
ating, but you can turn more sharply if you
apply throttle while turning the handlebars.
The OTS system 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.
Practice turning in an open area without ob-
stacles until you have a good feel for this
maneuver.

This watercraft is water-jet propelled. The
jet pump is directly connected to the engine.
This means that jet thrust will produce some
movement whenever the engine is running.
There is no “neutral” position. You are in ei-
ther “forward” or “reverse”, depending upon
the shift lever position.

Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or im-
pact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and broken
legs, ankles, and other bones. You could
also damage the shift mechanism.

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 thefuel 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.
To fill the fuel tank:
(1) Before refueling, turn off the engine. Do
not stand or sit on the watercraft. Never
refuel while smoking, or while in the vicin-
ity of sparks, open flames, or other sourc-
es of ignition.
(2) Place the watercraft in a well-ventilated
area and in a horizontal position.
(3) Remove the seats, and then check the
fuel level. (See page 24 for seat removal
and installation procedures.)
(4) Open the hood. (See page 25 for hood
opening and closing procedures.)
(5) Remove the fuel tank filler cap, and then
slowly add fuel to the fuel tank. Stop filling
when the fuel level reaches approximate-
ly 50 mm (2 in) from the top of the fuel
tank. Do not overfill the fuel tank. Be-
cause 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. Recommended fuel:
Regular unleaded gasoline with a mini-
mum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)

If water remains in the water separator, drain
it by removing the drain screw. Place a drain
pan under the water separator to catch the
draining water or use a dry cloth to soak up
any water that could spill into the watercraft. If
any water spills into the watercraft, be sure to
wipe it up with a dry cloth. Also, be sure to in-
stall the drain screw after draining the water
separator.
EJU32452Bilge
Check the bilge for moisture and fuel residue.
NOTICE: Excessive water in the engine
compartment can splash into the engine,
which can result in severe damage.
[ECJ00341]
This watercraft is equipped with a convention-
al jet vacuum bilge draining system and an
electric bilge draining system. The electric
bilge draining system is operated when the
engine is running. When excess water reach-
es the water inlet of the electric bilge pump,
the water is discharged from the electric bilge
pilot outlet at the stern.
A small quantity of water will remain in the
bilge and should be drained manually. To
drain any residual water, beach the watercraft
and perform the following procedure.
To drain water from the bilge:
(1) Remove the stern drain plugs.
(2) Raise the bow of the watercraft until the
water drains.(3) After the water has drained, wipe the
bilge with dry rags to make sure that it is
thoroughly dry.
(4) Install the stern drain plugs. NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads to remove
any foreign materials, such as dirt or
sand. Otherwise, the stern drain plugs
could be damaged, allowing water to
enter the engine compartment. Make
sure that the stern drain plugs are
tightened securely before launching
the watercraft. Otherwise, water may
flood the engine compartment and
cause the watercraft to submerge.

Stern drain plugs
Check the stern drain plugs for proper instal-
lation.
EJU32482Battery
Check the battery electrolyte level and check
that the battery has sufficient power to start
the engine easily. WARNING! Never operate
the watercraft if the battery does not have
sufficient power to start the engine or if it
shows any other signs of decreased pow-
er. Loss of battery power may leave you
stranded.

EJU32651Jet intake
Carefully check the jet intake for weeds, de-
bris, or anything else that might restrict the in-
take of water. If the jet intake is clogged, clean
it. (See page 85 for jet intake cleaning proce-
dures.)
If the watercraft is operated while the jet in-
take is clogged, cavitation could occur, reduc-
ing jet thrust, and possibly damaging the jet
pump. In some cases, the engine may over-
heat because of lack of cooling water, and
damage to the engine could result. Cooling
water is fed to the engine by the jet pump.
EJU32661Engine shut-off cord (lanyard)
Check that the engine shut-off cord (lanyard)
is not frayed or broken. If the cord is dam-
aged, replace it. WARNING! Never try to re-
pair the engine shut-off cord (lanyard) or
tie it together. The engine shut-off cord
(lanyard) may not pull free when the oper-
ator falls off, allowing the watercraft tocontinue to run and cause an accident.

Switches
NOTICE
ECJ00410
Do not run the engine for more than 15
seconds when checking the switches on
land without supplying water, otherwise
the engine could overheat.
Check the start switch, the engine stop
switch, and the engine shut-off switch for
proper operation.
Push the start switch to start the engine. As
soon as the engine starts running, push the
engine stop switch to verify that the engine
stops immediately. Restart the engine, and
then pull the engine shut-off cord (lanyard) to
remove the clip from the engine shut-off
switch to verify that the engine stops immedi-
ately. (See pages 26 to 27 for information on
proper operation of the start switch, the en-

which can result in severe damage.
[ECJ00541]
(3) Start the engine and operate the water-
craft as straight as possible and above
planing speed for at least 2 minutes to
discharge any water remaining in the en-
gine compartment. (If the engine does
not start, see “Towing the watercraft” on
page 88 or “Submerged watercraft” on
page 88.) NOTICE: Do not operate the
engine at full throttle for at least 1
minute after the engine has been re-
started. Excessive water in the engine
compartment can splash into the en-
gine, which can result in severe dam-
age.
[ECJ00551]
EJU33251
Turning the watercraft
WARNING
EWJ00770

Do not release the throttle lever when
trying to steer away from objects—youneed throttle to steer. A collision could
result in severe injury or death.

When operating at higher speeds, make
gradual turns or slow down before turn-
ing. Sharp high-speed turns may cause
the watercraft to slide sideways or spin,
throwing the operator and passengers
overboard, which could cause an injury.
Steering control depends on the combination
of handlebar position and the amount of throt-
tle.
Water sucked in through the intake grate is
pressurized by the impeller in the jet pump. As
the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.
