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.
EJU18410
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.

system. If the settings are changed poor
engine performance and damage may
result.
@

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: 1,550–1,750 r/min
