WARNING
EWJ00680
Do not start the engine on land if anyone is
behind the watercraft. Hot water and
steam spurting from the exhaust outlet
into the air can cause serious burns.
To keep your watercraft in top shape, always
take it out of the water after using it and per-
form the following procedures. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deterioration
of the jet unit components and hull finish. Ma-
rine organisms and corrosion are some of the
conditions that can adversely affect the life of
many watercraft components.
(1) Remove the watercraft from the water.
(2) Wash down the hull, handlebars, and jet
unit with fresh water.
(3) Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow the water in the bilge to
drain out.
NOTE:
This watercraft is equipped with a jet vacuum
bilge draining system and an electric bilge
draining system that remove water from the
engine compartment while you are underway.However, some residual water will remain.
(See page 39 for bilge draining procedures.)
(4) Place the watercraft in a horizontal posi-
tion.
(5) Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See
page 60 for flushing procedures.)
(6) Drain residual water from the exhaust
system by running the engine at 4000
r/min for 10 to 15 seconds.
CAUTION:
ECJ00600
Do not run the engine over 4000 r/min on
land, otherwise the catalytic converter
could be seriously damaged.
(7) If the watercraft will be stored for a week
or more, lubricate internal engine compo-
nents to help prevent corrosion. (See
page 61 for lubrication procedures.)
(8) Rinse the engine and engine compart-
ment with a small amount of water.
CAUTION:
ECJ00570
Do not use high-pressure water when rins-
ing the engine or engine compartment as
severe engine damage could result.
(9) Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3,
if necessary).
(10) Wipe the hull, handlebars, and jet unit dry
with a clean cloth.
(11) Spray a rust inhibitor on metallic parts to
minimize corrosion.
WARNING

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.

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:

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

Emergency procedures EJU34630Cleaning the jet intake and impeller
If weeds or debris get caught in the jet intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine speed
rises. If this condition is allowed to continue,
the engine will overheat and may seize. If
there is any sign that the jet intake or impeller
is clogged with weeds or debris, return to
shore and check the intake and impeller. Al-
ways stop the engine before beaching the wa-
tercraft.
WARNING
EWJ00780
Before attempting to remove weeds or de-
bris from the jet intake or impeller area,
shut the engine off and remove the clip
from the engine shut-off switch. Severe in-
jury or death could result from coming incontact with the rotating parts of the jet
pump.
CAUTION:
ECJ00650
If weeds or debris get caught in the jet in-
take, do not operate the watercraft above
trolling speed until they have been re-
moved.
(1) Turn the watercraft on its side as shown.
