Enjoy your watercraft
responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility
to treat these other people, and the lands,
waters, and wildlife with respect and courte-
sy.
Whenever and wherever you ride, think of
yourself as the guest of those around you.
Remember, for example, that the sound of
your watercraft may be music to you, but it
could be just noise to others. And the exciting
splash of your wake can make waves others
won’t enjoy.
Avoid riding close to shoreline homes and
waterfowl nesting areas or other wildlife ar-
eas, and keep a respectful distance from fish-
ermen, other boats, swimmers, and
populated beaches. When travel in areas like
these is unavoidable, ride slowly and obey all
laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within reg-
ulated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, pollution can be harmful to the
environment. Do not refuel or add oil where a
spill could cause damage to nature. Remove
your watercraft from the water and move it
away from the shoreline before refueling. Dis-
pose of water and any fuel and oil residue in
the engine compartment according to local
regulations. And keep your surroundings
pleasant for the people and wildlife that share
the waterways: don’t litter.When you ride responsibly, with respect and
courtesy for others, you help ensure that our
waterways stay open for the enjoyment of a
variety of recreational opportunities.

The “RPM” indicator light comes on when the
analog tachometer is selected.
To switch to the tachometer from the speed-
ometer:
Push the “SPEED/RPM” button for at least 1
second after the multifunction information
center is activated. When the meter switches
to the analog tachometer function, the
“RPM” indicator light comes on.
Analog speedometer
The analog speedometer shows the water-
craft speed against water.
The small inner numbers on the meter show
the watercraft speed in kilometers per hour
“km/h” and the large outer numbers show the
speed in miles per hour “mph”.
The “SPEED” indicator light comes on when
the analog speedometer is selected.
To switch to the speedometer from the ta-
chometer:
Push the “SPEED/RPM” button for at least 1
second after the multifunction information
center is activated. When the meter switches
to the analog speedometer function, the
“SPEED” indicator light comes on if “km/h”
are selected as the display units. The
“SPEED” indicator light blinks three times,then comes on, if “mph” are selected as the
display units. (See page 40 for information on

TIP:
The accuracy of the fuel level meter varies
depending on the operating conditions. Use
this function as a reference only.
EJU42342Fuel level warning
If the fuel remaining in the fuel tank drops to
about 18 L (4.8 US gal, 4.0 Imp.gal), the low-
est two fuel level segments, the fuel indicator,
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 57
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is re-
started.
TIP:
Push any of the operation buttons for the
multifunction information center to stop the
buzzer.
EJU42271Oil 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 to
shore, and then check the engine oil level.
(See page 60 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
multifunction information center to stop the
buzzer.
EJU42571Engine 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-

Engine oil requirementsEJU41513Engine oil
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 48 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 SG, SH, SJ, SL

(6) Loosen the engine oil filler cap and re-
move it.
(7) Slowly add engine oil.
TIP:
The difference between the minimum and
maximum level marks on the dipstick is equal
to approximately 1 L (1.06 US qt, 0.88 Imp.qt)
of engine oil.
(8) Wait approximately 5 minutes to allow
the engine oil to settle, and then check
the engine oil level again.
(9) Repeat steps 3–8 until the engine oil is at
the proper level.
(10) Securely install the engine oil filler cap by
tightening it until it stops.
(11) Securely install the seats in their original
positions.

Draining the bilge water
NOTICE
ECJ01302
Do not run the engine at full throttle when
bilge water remains in the engine com-
partment. The bilge water can splash into
the engine, which can result in severe
damage.
EJU44260Draining the bilge water on land
To drain the bilge water on land:
(1) Loosen the stern drain plugs and remove
them.
(2) Raise the bow of the watercraft, such as
by placing the watercraft on a slope, to
drain the bilge water from the engine
compartment.
(3) After the bilge water has drained from the
stern drain plug holes, wipe up any re-
maining moisture in the engine compart-
ment with a dry cloth.
(4) Check that the stern drain plugs and O-
rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs.
NOTICE: Before installing the stern
drain plugs, clean the drain plug
threads and the O-rings on the plugs
to remove any foreign materials, such
as dirt or sand. Otherwise, the stern1Engine oil filler cap

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 60
for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en-
gine. (See page 76 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.
