EJU31370Yamaha Engine Management System
(YEMS)
This model is equipped with an integrated,
computerized management system that con-
trols and adjusts ignition timing, fuel injection,
engine diagnostics, and the off-throttle steer-
ing (OTS) system.
EJU36290Yamaha Security System
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The engine cannot be started if the
security system is in the lock mode. The en-
gine can only be started in the unlock mode.
This watercraft is equipped with a remote con-
trol transmitter that is used to select the lock
and unlock modes of the security system.
Since the watercraft is programmed to recog-
nize the internal code from this transmitter
only, the security system mode can only be
changed with this transmitter.
If you lose the remote control transmitter or it
does not operate properly, contact a Yamaha
dealer.

EJU35122Oil pressure warning indicator
If the oil pressure does not rise to specifica-
tion, the “WARNING” indicator light and the oil
pressure warning indicator begin to blink, and
the buzzer sounds intermittently. At the same
time, the engine speed is limited to help pre-
vent damage.
If this occurs, reduce the engine speed, return
to shore, and then check the engine oil level.
(See page 53 for engine oil level checking
procedures.) If the oil level is low, add enough
engine oil to raise it to the proper level. If the
oil level is sufficient, have a Yamaha dealer
check the watercraft.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.
EJU36401Engine overheat warning indicator
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the engine
overheat warning system will be activated
and, in some cases, the warning system will
cut the ignition to the engine.
If the “WARNING” indicator light and the en-
gine overheat warning indicator begin to blink,
and the buzzer sounds intermittently, immedi-ately reduce the engine speed and return to
shore.
If the “WARNING” indicator light and the en-
gine overheat warning indicator come on, and
the buzzer sounds continuously, the warning
system will cut the ignition. The engine cannot
be started until it cools down, so it may be
necessary to have the watercraft towed back
to the shore. (See “Towing the watercraft” on
page 97 for towing procedures.)
After the engine cools down, start the engine,
and then check for water discharge at the port
(left) cooling water pilot outlet while the engine
is running. If there is no discharge of water,
shut the engine off, and then check the intake
grate and impeller for clogging.
WARNING
EWJ00050
Before attempting to remove weeds or de-
bris from the intake grate or impeller, shut
the engine off and remove the clip from the

Fuel and oil
This watercraft is equipped with a 4-stroke en-
gine. Conventional 2-stroke engine oil cannot
be used.
The engine utilizes an electronic fuel injection
system to deliver the optimal air-fuel ratio re-
quired by the engine. By ensuring the optimal
combustion conditions, this system is able to
increase startability and improve fuel econo-
my.
EJU36330Gasoline
WARNING
EWJ00280
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and keep
away from sparks, flames, and other
sources of ignition.

Stop the engine before refueling.

Refuel in a well-ventilated area with the
watercraft in a horizontal position.

Do not stand or sit on the watercraft
while refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level reaches approxi-
mately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do not
leave it in direct sunlight. Leave it in a
well-ventilated area with the watercraft
in a horizontal position.

Tighten the fuel tank filler cap securely
after refueling.

If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso-
line in your eyes, get immediate medical
attention.

If any gasoline spills on your skin or
clothing, immediately wash the affected
area with soap and water and change
your clothes.
CAUTION:
ECJ00320

Do not use leaded gasoline. Leaded gas-
oline can seriously damage the catalytic
converter.

Use only fresh gasoline that has been
stored in clean containers.
EJU31860Gasohol
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.
Gasohol containing methanol is not recom-
mended by Yamaha because it can cause
fuel system damage and engine performance
problems.Recommended gasoline:
Regular unleaded gasoline with a mini-
mum octane rating of
86 (Pump octane number) = (R +
M)/2
90 (Research octane number)

EJU34381Cleaning and adjusting the spark
plugs
The spark plug is an important engine compo-
nent and is easy to inspect. The condition of
the spark plug can indicate something about
the condition of the engine. For example, if
one spark plug has a distinctly different color,
the engine could require servicing. Do not at-
tempt to diagnose any problems yourself.
Have a Yamaha dealer service the watercraft.
Remove and inspect the spark plugs periodi-
cally; heat and deposits will cause the spark
plugs to slowly break down and erode. If elec-
trode erosion becomes excessive, or if carbon
and other deposits are excessive, replace the
spark plug with the specified plug.
To remove a spark plug:
(1) Remove the air filter case cover and air
filter element. (See page 84 for air filter
element removal and installation proce-
dures.)
(2) Remove the spark plug cap.
CAUTION:
ECJ00210
Do not use any tools to remove or install
the spark plug cap, otherwise the ignition
coil coupler could be damaged. The spark
plug cap may be difficult to remove be-
cause the rubber seal on the end of the
cap fits tightly. To remove the spark plug
cap, simply twist it back and forth while
pulling it up; to install it, twist it back and
forth while pushing it down.
(3) Remove the spark plug.
Measure the spark plug gap with a wire
thickness gauge. Replace the spark plugor adjust the gap to specification if neces-
sary.
To install a spark plug:
(1) Clean the gasket surface.
(2) Wipe any dirt from the threads of the
spark plug.
(3) Install the spark plug, and then tighten it
to the specified torque.
(4) Install the spark plug cap.
NOTE:

Wipe off any water on the spark plug or in-
side the spark plug cap before installing the
cap. Push the spark plug cap down until it is
securely installed.

If a torque wrench is not available when you
are installing a spark plug, a good estimate
of the correct torque is 1/4 turn to 1/2 turn
past finger tight using the spark plug
wrench included in the tool kit. Have the
spark plug adjusted to the correct torque
with a torque wrench as soon as possible.
