If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is
being discharged from the port (left) cooling
water pilot outlet while the engine is running.
If there is no discharge of water, stop the en-
gine, and then check the jet intake for clog-
ging. (See page 100 for information on the jet
intake.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-
ate at higher speeds could result in severe
engine damage.

TIP:
While the engine overheat warning is acti-
vated, the maximum engine speed is limit-
ed.
Tap “ ” to display a description of the

Oil pressure warning “ ”
If the oil pressure drops significantly, the
warning bar is shown instead of the tachom-
eter value display, “ ” and “ ” are
shown, and the buzzer sounds intermittently.
If the oil pressure warning is activated, imme-
diately reduce the engine speed, return to
shore, and then check the engine oil level.(See page 59 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
While the oil pressure warning is activated,
the maximum engine speed is limited.
Tap “ ” to display a description of the
warning in the center display.
Other warnings (communication errors,
exceeding the maintenance intervals, and
so on) “ ”
If any other malfunction is detected or if the
engine has been operated for more than 50

NOTICE
ECJ00282
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
TIP:
When the engine is operated at high speeds,
some engine oil may be consumed. Be sure
to check the engine oil level.
Checking the engine oil level
WARNING
EWJ00341
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
ECJ01002
Make sure that debris and water do not
enter 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 engine oil to settle by waiting 5 minu-
tes or more before checking the oil level.
(2) Remove the seats. (See page 49 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:
API SJ, SL

Engine break-in
NOTICE
ECJ00432
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 59
for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en-
gine. (See page 75 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 90 minutes, operate with the
engine speed below 5000 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.

EJU32424Water separator check
Make sure that no water has collected in the
water separator. If water has collected in the
water separator, drain it. (See page 29 for in-
formation on draining the water separator.)
EJU40182Engine unit check
Check the exterior of the engine unit for dam-
age or other problem.
EJU36886Engine oil level check
Make sure that the engine oil level is between
the minimum and maximum level marks onthe dipstick. (See page 59 for information on
checking the engine oil level.)
EJU32456Bilge 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 60 for information on draining the
bilge water.)
EJU32485Battery 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
ventilated. 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.
[ECJ00242]
If distilled water was added, check the bat-
tery 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 pro-
vided with the battery tester and charger you
use. NOTICE: Do not attempt to charge a
battery hastily. Battery life could be short-
ened.
