and the “WARNING” indicator light blink, and
the buzzer sounds intermittently.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 55
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is restart-
ed.
TIP:
Push any of the operation buttons for the mul-
tifunction information center to stop the buzz-

EJU42270Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator and the “WARN-
ING” indicator light blink, and the buzzer
sounds intermittently. At the same time, the
engine speed is limited.
If the oil pressure warning is activated, imme-
diately reduce the engine speed, return toshore, and then check the engine oil level.
(See page 57 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
Push any of the operation buttons for the mul-
tifunction information center to stop the buzz-
er.
EJU42570Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. Then, the en-
gine overheat warning indicator and the
“WARNING” indicator light stop blinking and
remain on, and the buzzer sounds continu-
ously. At the same time, the engine speed is
limited.
If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is be-
ing discharged from the cooling water pilot
outlet while the engine is running. If there is no
discharge of water, stop the engine, and then
check the jet intake for clogging. (See page
99 for information on the jet intake.) NOTICE:
If you cannot locate and correct the cause
of the overheating, consult a Yamaha deal-
er. Continuing to operate at higher speeds

NOTICE
ECJ00281
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
Checking the engine oil level
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.
If the engine was running, allow the en-
gine oil to settle by waiting 5 minutes or
more before checking the oil level.
(2) Remove the seats. (See page 46 for seat
removal and installation procedures.)(3) Remove the dipstick and wipe it clean.
(4) Insert the dipstick back into the dipstick
tube completely. Remove the dipstick
again and make sure that the engine oil
level is between the minimum and maxi-
mum level marks.
(5) If the engine oil level is significantly above
the maximum level mark, consult a
Yamaha dealer. If the engine oil level is
below the minimum level mark, add en-
gine oil. Recommended engine oil type:
SAE 10W-30, 10W-40, 20W-40, 20W-
50
Recommended engine oil grade:

Engine break-in
NOTICE
ECJ00431
Failure to perform the engine break-in
could result in reduced engine life or even
severe engine damage.
The engine break-in is essential to allow the
various components of the engine to wear
and polish themselves to the correct operat-
ing clearances. This ensures proper perfor-
mance and promotes longer component life.
To perform the engine break-in:
(1) Check the engine oil level. (See page 57
for information on checking the engine oil
level.)
(2) Launch the watercraft and start the en-
gine. (See page 73 for information on
starting the engine.)
(3) For the first 5 minutes, operate with the
engine speed at 2000 r/min.
(4) For the next 30 minutes, operate with the
engine speed below 5000 r/min.
(5) For the next 1 hour, operate with the en-
gine speed below 6000 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.

formation on draining the water separator.)
EJU40181Engine unit check
Check the exterior of the engine unit for dam-
age or other problem.
EJU36885Engine oil level check
Make sure that the engine oil level is between
the minimum and maximum level marks onthe dipstick. (See page 57 for information on
checking the engine oil level.)
EJU32455Bilge water check
Make sure that no bilge water has collected in
the engine compartment. If bilge water has
collected in the engine compartment, drain it.
(See page 58 for information on draining the
bilge water.)
EJU32484Battery checks
Make sure that the battery terminals and
breather hose are not damaged and that the
battery leads and breather hose are connect-
ed properly. WARNING! Fire or explosion
could result if the breather hose is dam-

egg, or vegetable oil. Call a physician im-
mediately.
Eyes: Flush with water for 15 minutes and
get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flames, cigarettes, etc., well away.
If using or charging the battery in an en-
closed space, make sure that it is well ven-
tilated. Always shield your eyes when
working near batteries.
Keep out of the reach of children.
To remove the battery:
(1) Disconnect the negative (–) battery lead.
(2) Disconnect the positive (+) battery lead.
(3) Disconnect the breather hose.
(4) Unhook the battery bands, and then re-
move the battery from the watercraft.
Checking the battery
●Make sure that the battery case is not dam-
aged.
●Make sure that the battery terminals are not
corroded or damaged.
●Make sure that the breather hose is not
clogged or damaged.Checking the electrolyte level
Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
If the electrolyte level is low, add distilled wa-
ter to raise it to the specified level. NOTICE:
Use only distilled water for replenishing
the battery, otherwise battery life could be
shortened.
[ECJ00241]
If distilled water was added, check the battery
voltage.
It is recommended to have a Yamaha dealer
check the battery voltage and charge the bat-
tery. If you charge the battery yourself, be
sure to read and follow the instructions provid-
ed with the battery tester and charger you
use. NOTICE: Do not attempt to charge a
battery hastily. Battery life could be short-
ened.
