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.

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.
[ECJ00042]
TIP:
While the engine overheat warning is acti-
vated, the maximum engine speed is limit-
ed.
Tap “ ” to display a description of the
warning in the center display.
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
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.
If a warning is activated, have the watercraft
serviced by a Yamaha dealer as soon as pos-
sible.

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 ba-
lance 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 minu-
tes or more before checking the oil level.
(2) Remove the seats. (See page 49 for seat removal and installation procedures.)
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

(3) Remove the dipstick and wipe it clean.
(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 59for 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 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.
