TIP:
Press the select button on the multifunction
information center to stop the buzzer.
EJU31622Oil pressure warning indicator
If the oil pressure does not rise to specifica-
tion, the “WARNING” light and the oil pres-
sure warning indicator begin to blink, and the
buzzer sounds intermittently. At the same
time, the engine speed is limited to help pre-
vent damage.
If this occurs, reduce the engine speed, return
to shore, and then check the engine oil level.
(See page 42 for engine oil level checking
procedures.) If the oil level is low, add enough
engine oil to raise it to the proper level. If the
oil level is sufficient, have a Yamaha dealer
check the watercraft.
TIP:
Press the select button on the multifunction
information center to stop the buzzer.
EJU31605Engine overheat warning indicator
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the “WARN-
ING” light and the engine overheat warning in-
dicator blink, and then come on. The buzzer
also begins to sound intermittently, and then it
sounds continuously. After the light and indi-
cator start to blink and the buzzer sounds, the
engine speed is limited to help prevent dam-
age.
If this occurs, immediately reduce the engine
speed, return to shore, and then check for wa-
ter discharge at the port (left) cooling water pi-
lot outlet while the engine is running. If there
is no discharge of water, shut the engine off,

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 seat. (See page 23 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.
EJU32391Fuel 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 68 for
check points and correct procedures.)(1) Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
(2) Remove the seat. (See page 23 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 38 for
filling procedures.)
(4) Install the fuel tank filler cap and the seat.
EJU32401Engine 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

not enough oil in the oil tank, otherwise
the engine could be damaged.

enter the oil tank 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 horizontal posi-
tion or launch the watercraft, and then
start the engine. NOTICE: When check-
ing the engine oil level on land, supply
water to the cooling water passages.
(See page 62 for procedures on sup-
plying water.)
[ECJ01020]

moor the watercraft so that it will not drift
away.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.
