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.

EJU46400Warning function
The multifunction information center can indi-
cate the following warnings.
Fuel level warning
Battery voltage warning
Check engine warning
Engine overheat warning
Oil pressure warning
Other warnings (communication errors, ex-
ceeding the maintenance intervals, and so
on)
To stop the buzzer when a malfunction is ac-
tivated, correct the cause of the problem and
start the engine again, or push the “OK” but-
ton of the touchpad control.
Fuel level warning
If the amount of remaining fuel is low, the low-
est fuel level segment blinks orange, “Low
Fuel” is displayed on the display, and the
buzzer sounds intermittently. If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 54
for information on filling the fuel tank.)
Battery voltage warning
If the battery voltage is less than 12 volts or
more than 18 volts when the engine is not
running, the voltage display of the voltmeter
blinks.
If the battery voltage warning is activated,
have the watercraft serviced by a Yamaha
dealer as soon as possible.
Check engine warning “ ”
If a sensor malfunction or a short circuit is
detected, “ ” is shown in the warning bar,
and the buzzer sounds intermittently.
If the check engine warning is activated, im-
mediately reduce the engine speed, return to

engine.
TIP
Push the “OK” button of the touchpad control
to display a description of the warning in the
center display.
Engine overheat warning “ ”
If the engine temperature rises
significantly, “ ” and “ ” are shown in the
warning bar, and the buzzer sounds continu-
ously.
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 97 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.
[ECJ00042]
TIP
While the engine overheat warning is acti-
vated, the maximum engine speed is limit-
ed.
Push the “OK” button of the touchpad con-
trol to display a description of the warning
in the center display.
Oil pressure warning “ ”
If the oil pressure drops significantly, “ ”
and “ ” are shown in the warning bar, 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 56 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.
Push the “OK” button of the touchpad con-
trol 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
hours since the last maintenance, the warn-
ing bar is shown instead of the tachometer
value display, “ ” is shown, and the buzz-
er sounds intermittently.

Engine oil requirementsEJU41514Engine oilECJ00282
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.
Why Yamalube
YAMALUBE oil is a Genuine YAMAHA Part
born of the engineers’ passion and belief that
engine oil is an important liquid engine com-
ponent. We form teams of specialists in the
fields of mechanical engineering, chemistry,
electronics and track testing, and have them
develop the engine together with the oil it will
use. Yamalube oils take full advantage of the
base oil’s qualities and blend in the ideal bal-
ance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and syn- thetic oils have their own distinct characters
and value. Yamaha’s experience gained over
many years of research and development
into oil since the 1960’s helps make
Yamalube the best choice for your Yamaha engine. Checking the engine oil level
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.
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 min-
utes or more before checking the oil lev-
el.
(2) Remove the seats. (See page 47 for seat removal and installation procedures.)
(3) Remove the dipstick and wipe it clean.
Recommended engine oil:
YAMALUBE 4W or 4-stroke motor oil
Recommended engine oil type: SAE 10W-30, 10W-40, 20W-40,
20W-50
Recommended engine oil grade: API SG, SH, SJ, SL

(4) Insert the dipstick back into the dipsticktube 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.
(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.

Engine break-inECJ00432
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 56for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en- gine. (See page 71 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.
