Identification numbers
Record the Primary Identification (PRI-ID)
number, Craft Identification Number (CIN),
and engine serial number in the spaces pro-
vided for assistance when ordering spare
parts from a Yamaha dealer. Also record and
keep these ID numbers in a separate place in
case your watercraft is stolen.
EJU30284Primary Identification (PRI-ID) number
The PRI-ID number is stamped on a plate at-
tached inside the engine compartment. (See
page 38 for seat removal and installation pro-
cedures and page 42 for information on the
seat storage compartment.)

Control function operation

zle is changed, and the direction of the water-
craft is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn,
except at trolling speed.
This model is equipped with the Yamaha En-
gine Management System (YEMS) that in-
cludes an off-throttle steering (OTS) system.
It will activate at planing speeds should you
attempt to steer the watercraft after releasing
the throttle lever. The OTS system assists in
turning by continuing to supply some thrust
while the watercraft is decelerating, but you
can turn more sharply if you apply throttle
while turning the handlebars. The OTS sys-
tem does not function below planing speeds
or when the engine is off. Once the engine
slows down, the watercraft will no longer turn
in response to handlebar input until you apply
throttle again or you reach trolling speed.EJU35975Cooling water pilot outlet
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlet.
There is a cooling water pilot outlet on the
port (left) side of the watercraft. To check for
proper operation of the cooling system, make
sure that water is being discharged from the
cooling water pilot outlet. If water is not being
discharged from the outlet, stop the engine
and check the jet intake for clogging. (See
page 90 for information on the jet intake.)
TIP:
It will take about 60 seconds for the water
to reach the outlet after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.

Operation
68
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-
