to shore, and then make sure that water is
being discharged from the cooling water pilot
outlet while the engine is running. If there is
no discharge of water, stop the engine, and
then check the jet intake for clogging. (See
page 90 for information on the jet intake.)

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
ECJ00392
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 75 for information on
supplying water.)
When checking the engine oil level on wa-
ter, moor the watercraft so that it will not
drift away.

Operating your watercraft
WARNING
EWJ00511
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
EJU32965Getting to know your watercraft
Operating your watercraft requires skills ac-
quired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneu-
vers.
Operating your new watercraft can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar-
ize yourself with the operation of the water-
craft to achieve the skill level necessary to
enjoy riding safely.
Before operating this watercraft, read this
owner’s/operator’s manual, the Riding Prac-
tice Guide, the Riding Instruction card, and all
labels on the watercraft. Pay particular atten-
tion to the safety information beginning on
page 10. These materials should give you an
understanding of the watercraft and its oper-
ation.
Remember: This watercraft is designed to
carry the operator and up to 2 passengers.
Never exceed the maximum load limit or al-
low more than 3 persons (or 2 persons if a
wakeboarder or water-skier is being pulled)
to ride the watercraft at any time.
EJU33006Learning to operate your watercraft
Before operating the watercraft, always per-
form the pre-operation checks listed on page
51. The short time spent checking the water-
craft will reward you with added safety and
reliability.
Check local laws before operating your wa-
tercraft.
Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other watercraft. Select a wide area to
learn in, where there is good visibility and
light boat traffic.
Use the buddy system—operate with some-
one nearby. Scan constantly for people, ob-
jects, and other watercraft. Be alert for
conditions that limit your visibility or block
your vision of others.
You should grip the handlebars firmly and
keep both feet on the floor of the footwell. Do
not attempt to ride with passengers until your
operating skills are fully developed.Maximum load:
220 kg (486 lb)
Load is the total weight of cargo, op-
erator, and passengers.

Operating in reverse (EX Deluxe)
When the RiDE lever is squeezed, the “R” (re-
verse) shift indicator will be displayed and the
watercraft will move in reverse. (See page 29
for shift system operation procedures.)
Make sure that there are no obstacles or peo-
ple behind you before shifting into reverse.
TIP:
This model is equipped with a function which
limits the engine speed in reverse.
Operating in neutral (EX Deluxe)
When the RiDE lever is squeezed lightly and
released, the “N” (neutral) shift indicator will
be displayed and the watercraft will stop in itscurrent location. (See page 29 for shift sys-
tem operation procedures.)
EJU36087Boarding the watercraft
WARNING
EWJ01112
Be sure the operator and any passengers
have practiced boarding from the water
while still close to shore before riding. A
person who has made many unsuccessful
attempts to get back on the watercraft
may become fatigued and suffer from ex-
posure, increasing the risk of injury and
drowning.
Board the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep from the bottom of the watercraft.
NOTICE: Never run the engine in water
that is less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise peb-
