Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
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

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.

Do not run the engine with too much or
not enough oil in the oil tank, otherwise
the engine could be damaged.
Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
TIP
When checking the engine oil level on land,
the engine must be running while water is
being supplied to the cooling water pas-
sages. (See “Flushing the cooling water
passages” on page 91 for information on
supplying water.)
When checking the engine oil level on wa-
ter, moor the watercraft so that it will not
drift away.
To check the engine oil level:
(1) With the engine stopped, place the wa-
tercraft in a precisely level position on
land or launch the watercraft.
(2) Look in all directions, and then start the engine. (See page 78 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 mi- nutes or more. Run the engine an addi-
tional 5 minutes if the ambient
temperature is 20 °C (68 °F) or less.
(4) Stop the engine.
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

(5) Remove the seats. (See page 54 for seatremoval and installation procedures.)
(6) Loosen the oil tank filler cap and remove it, and then wipe the attached dipstick
clean.
(7) Screw the oil tank filler cap into the filler hole until it stops. Remove the oil tank
filler cap again and make sure that the
engine oil level is between the minimum
and maximum level marks.
(8) 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, slowly
add engine oil.
(9) Repeat steps 6–8 until the engine oil is at the proper level. (10) Securely install the oil tank filler cap and
turn 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 63for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en- gine. (See page 78 for information on
starting the engine.)
(3) For the first 5 minutes, operate with the engine at idling speed.
(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 6500 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.
