EJU34210Checking the fuel system
WARNING
EWJ00380
Gasoline is highly flammable and explo-
sive. Failure to check for and repair any
fuel leakage could result in a fire or explo-
sion. A fire or explosion can cause severe
injury or death. Shut the engine off. Do not
smoke. Avoid spilling gasoline.
Fuel in the fuel lines is pressurized.
Fuel can spray out and cause injury or a
fire hazard if a fuel line is disconnected.
Do not run the engine with a fuel line dis-
connected.
Check the fuel system for leaks, cracks, and
malfunctions. If any problem is found, consult
a Yamaha dealer.
Check:

Fuel tank filler cap and seal for damage.

Fuel in fuel tank for water and dirt.

Fuel tank for damage, cracks, and leakage.

Fuel hoses and joints for damage, cracks,
and leakage.

Air bleeding passages for leakage.EJU34230Fuel tank
Check the fuel tank for leakage and for 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.
EJU34240Checking the oil injection system
Check the oil injection system for leakage,
cracks, and malfunctions. Have a Yamaha
dealer repair the oil injection system if neces-
sary.
Check:

Oil tank for damage, cracks, and leakage.

Oil in the oil tank for water and dirt.

Oil hoses and joints for damage, cracks,
and leakage.

Oil filter for dirt.

Oil pump for leakage.EJU34250Oil tank
Check the oil tank for leakage and for water in
the tank. If water is found in the oil injection
system, or if the oil tank needs to be cleaned,
have a Yamaha dealer service the watercraft.
EJU34260Oil filter
Have a Yamaha dealer check the oil filter for
dirt and clogs.
EJU34320Checking the jet thrust nozzle angle
Check the handlebars and jet thrust nozzle for
smooth operation.
Turn the handlebars as far as possible to the
right and left and check that the difference of
distances A and B between the jet thrust noz-
zle and the nozzle is within specification.

Maintenance and care

If the steering is stiff or misadjusted, have a
Yamaha dealer service it.
EJU34360Checking and adjusting the throttle
cable
Check that the throttle cable moves back to
the set position smoothly and that the throttle
lever free play is within specification.
(1) Squeeze and release the throttle lever. If
the throttle lever does not return smooth-
ly, have a Yamaha dealer service it.(2) Adjust the free play by loosening the lock-
nut and turning the adjuster.
EJU34371Cleaning and adjusting the spark
plugs
WARNING
EWJ00350
Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks to
escape, which could result in a fire or ex-
plosion.
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 the
center electrode porcelain is very white, this
could indicate an intake air leak or carburetion
problem in that cylinder. Do not attempt to di-
agnose 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 Difference of A and B:

EJU34490Fuel injection system
The fuel injection system was set at the
Yamaha factory. If the fuel injection system
needs to be adjusted, have a Yamaha dealer
service the watercraft.
CAUTION:
ECJ00220
Do not attempt to adjust the fuel injection
system. If the settings are disturbed by
someone who does not have the neces-
sary technical knowledge, poor engine
performance and damage may result.
EJU34500Checking the trolling speed
(1) Place the watercraft in the water.
(2) Start the engine and warm it up. Use the
tachometer in the multifunction informa-
tion center to check the trolling speed.
If the trolling speed is out of specification,
have a Yamaha dealer service the watercraft.
EJU34520Bleeding the oil pump
If the oil tank becomes completely empty, or
any hose connected to the oil pump has been
disconnected, the oil pump must be bled to
ensure proper oil flow.
If necessary, have a Yamaha dealer bleed the
oil pump.
EJU36190Adjusting the Yamaha Adjustable
Sponsons (YAS)
The Yamaha Adjustable Sponsons can be
adjusted to two positions to enhance water-
craft performance according to operator pref-
erence and operating conditions. (See page
33 for an explanation of the positions.)To adjust the YAS:
(1) Remove the bolts on both sponsons.
(2) Remove the sponsons, and then install
them in the desired position.
NOTE:
Be sure to install both sponsons in the same
position.
(3) Tighten the sponson bolts to the specified
torque. Trolling speed:
1350 ±100 r/min
