Fuel system
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!

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

Stop 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 approx-
imately 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 water-
craft in a horizontal position.

Tighten the filler cap securely after
refueling.

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

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
Top off the fuel tank with fresh gasoline
and add fuel stabilizer and conditioner to the
fuel tank by following the manufacturer’s
instructions carefully.

Inspecting the fuel system
WARNING@ Gasoline is highly flammable and explo-
sive. Failure to check for and repair any
fuel leakage could result in fire or explo-
sion. A fire or explosion can cause
severe injury or death. Shut off the
engine. Do not smoke. Avoid spilling
gasoline.
Fuel in hose is pressurized.
Fuel can spray out and cause injury or a
fire hazard if fuel line is disconnected.
Do not attempt to run engine with fuel
line disconnected.
Check the fuel system for leaks, cracks,
or malfunctions. If any problem is found,
consult a Yamaha dealer.
Check:

Fuel tank for water or dirt.

Fuel tank cap (seal) for damage.

Fuel tank for damage, cracks or leakage.

Fuel hose joint for leakage.

Fuel hose for cracks or other damage.

Air bleeding passages for leakage.
EJU01841
Fuel tank
Check the fuel tank 1 for leakage or
water in the tank. If water is found in the fuel
system or if the fuel tank needs to be
cleaned, have a Yamaha dealer service the
watercraft.

Adjusting the fuel injection
system
The fuel injection system was set at the
Yamaha factory. Have a Yamaha dealer ser-
vice the watercraft if necessary.
CAUTION:@ Do not attempt to adjust the fuel injection
system. If the settings are changed poor
engine performance and damage may
result.

EJU18240
Checking the trolling speed
1. Put the watercraft in the water.
2. Start the engine and warm it up. Use the
tachometer in the multifunction meter to
check the trolling speed.
If the trolling speed is out of specification,
have a Yamaha dealer make this adjust-
ment. Trolling speed: 1,600–1,700 r/min

Submerged watercraft
If the watercraft is submerged or flooded
with water, follow the procedure below and
consult a Yamaha dealer as soon as possi-
ble. Failure to do so may result in serious
engine damage!
In an emergency:
1. Beach the watercraft and remove the
stern drain plugs to drain the water from
the engine compartment. (See page 3-9
for further instructions.) Remove the
storage compartment drain plugs to
drain the water from the storage com-
partments.
2. Install the stern drain plugs and storage
compartment drain plugs.
3. Disconnect the spark plug caps, and
then remove the spark plugs.
CAUTION:@ Do not connect the spark plugs to the
spark plug caps.
@
4. Disconnect the fuel injector couplers.
CAUTION:@ Cover the disconnected fuel injector cou-
plers so that they do not get wet. If the
couplers get wet, they could corrode,
which could lead to poor connections.
@
5. Crank the engine for 5 seconds at wide
open throttle. Repeat this step until all of
the water in the cylinders has been
expelled.
6. Spray a rust inhibitor into each spark
plug hole for 5 seconds.
7. Crank the engine for 5 seconds at wide
open throttle. Repeat this step several
times.

E
CAUTION:@ Do not start the engine even after com-
pleting the previous steps. Any water
remaining in the engine could cause seri-
ous engine damage.
@
8. Install the spark plugs, and then connect
the spark plug caps and fuel injector
couplers.
9. Have the watercraft inspected by a
Yamaha dealer as soon as possible.
CAUTION:@ Be sure to have a Yamaha dealer inspect
the watercraft. Otherwise, serious engine
damage could result.
