EJU32280Pre-operation check points EJU32331Engine compartment
WARNING
EWJ00460
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak or
a loose electrical connection.
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seats. (See page 25 for seat removal and
installation procedures.) Leave the engine
compartment open for a few minutes to allow
any fuel vapors to escape.
While the engine compartment is open, check
for loose electrical connections.
EJU32350Hull and deck
Check the hull and deck for cracks and other
damage. If any damage is found, have a
Yamaha dealer repair the watercraft.
EJU36871Fuel level
Make sure that there is sufficient fuel in the
fuel tank before each use.
Also, check the fuel system for leakage,
cracks, and malfunctions. (See page 83 for
check points and correct procedures.)
(1) Open the hood and remove the fuel tank
filler cap to release any pressure thatmight have built up in the fuel tank. (See
page 26 for hood opening and closing
procedures.)
(2) Remove the seats. (See page 25 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 52 for
filling procedures.)
(4) Install the fuel tank filler cap, and then
close the hood and install the seats.
EJU36882Engine oil level
Check the engine oil level before each use.
WARNING
EWJ00340
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ01001
Make sure that debris and water do not en-
ter the oil filler hole. Debris and water in
the engine oil can cause serious engine
damage.
To check the engine oil level:
(1) Place the watercraft in a precisely level
position on land with the engine stopped.
TIP:
If the engine was running, allow the engine oil
to settle by waiting 5 minutes or more before
checking the oil level.
(2) Remove the seats. (See page 25 for seat
removal and installation procedures.)
(3) Remove the dipstick, wipe it clean, and
then insert it back into the dipstick tube
completely. Remove the dipstick again
and check that the engine oil level is be-

tween the minimum and maximum level
marks.
(4) If the engine oil level is below the mini-
mum level mark, perform steps 5–7 to
add enough oil so that the oil level is be-
tween the minimum and maximum level
marks on the dipstick. If the engine oil lev-
el is significantly above the maximum lev-
el mark, have a Yamaha dealer service
the watercraft.(5) Remove the engine oil filler cap.
(6) Pour engine oil into the filler hole. Wait
approximately 5 minutes until the engine
oil settles.
TIP:
The difference between the minimum and
maximum level marks on the dipstick is equal
to approximately 1 liter of engine oil.
(7) Repeat steps 3–6 until the engine oil is at
the proper level.
(8) Install the engine oil filler cap, and then
install the seats.
EJU32420Water separator
Check the water separator for water. The wa-
ter separator retains any water that may have
entered through the fuel tank breather hose if
the watercraft was capsized. Normally, the
water separator is empty.

Operation
WARNING
EWJ00510
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
NOTICE
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU36661Engine break-in
NOTICE
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
The engine break-in period is essential to al-
low the various components of the engine to
wear and polish themselves to the correct op-
erating clearances. This ensures proper per-
formance and promotes longer component
life.
TIP:
Be sure to check the engine oil level before
operating the watercraft for the first time. (See
page 56 for engine oil checking procedures.)
(1) Launch the watercraft and start the en-
gine. (See page 64 for engine starting
procedures.)
(2) For the first 5 minutes, run the engine at
trolling speed only. For the 30 minutes of
operation after that, keep the engine
speed below 5000 r/min. For the 1 hour of
operation after that, keep the engine
speed below 6000 r/min.
(3) Proceed with normal operation.
EJU32801Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles behind you.
Use the remote control transmitter to select
the unlock mode. (See page 35 for Yamaha
Security System lock and unlock mode selec-
tion procedures.)
After the watercraft is in the water, start the
engine. Shift into reverse and move the water-
craft back slowly. If there are waves, some-
one should make sure that the watercraft is
not pushed into the trailer before backing
away.
EJU36341Starting the engine
(1) If the lock mode of the Yamaha Security
System is selected, use the remote con-
trol transmitter to select the unlock mode.
(See page 35 for Yamaha Security Sys-
tem lock and unlock mode selection pro-
cedures.)
(2) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep from the bottom of the watercraft.
NOTICE: Never operate in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise

EJU34212Checking the fuel system
WARNING
EWJ00381
Leaking fuel can result in fire or explosion.

Check for fuel leakage regularly.

If any fuel leakage is found, the fuel sys-
tem must be repaired by a qualified me-
chanic. Improper repairs can make the
watercraft unsafe to operate.
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 leakageEJU34230Fuel 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.
EJU36951Engine oil and oil filter
WARNING
EWJ00340
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ00991
Do not run the engine with too much or not
enough oil in the engine, otherwise the en-
gine could be damaged.
It is recommended to have a Yamaha dealer
change the engine oil. However, if you choose
to change the oil on your own, consult a
Yamaha dealer.
EJU34311Air filter element
Have a Yamaha dealer check the air filter ele-
ment at the intervals specified in the periodic
maintenance chart.
EJU34321Checking 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.1Fuel tank

EJU37041Cleaning 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
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 seats. (See page 25 for seat
removal and installation procedures.)
(2) Remove the engine cover screws, and
then remove the engine cover.
(3) Remove the spark plug cap bolts, and
then remove the spark plug cap.
NOTICE: Do not use any tools to re-
move 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.
