Safety information
The safe use and operation of this
watercraft is dependent upon the use of
proper riding techniques, as well as upon
the common sense, good judgment, and
expertise of the operator. Before using
this watercraft, make sure that its use is
permitted under local laws, bylaws and
regulations and always operate the
watercraft in full conformity with any
requirements and limitations imposed.
Every operator should know the follow-
ing requirements before riding the water-
craft.

Before operating the watercraft, read this
Owner’s/Operator’s Manual, the Riding
Practice Guide, and all warning and cau-
tion labels on the watercraft. These mate-
rials should give you an understanding of

Yamaha recommends a minimum opera-
tor age of 16 years old.

requirements.

This watercraft is designed to carry the
operator and one passenger. Never
exceed the maximum load limit or allow
more than 2 persons to ride the watercraft

become accustomed to the handling
characteristics of the watercraft before
trying any difficult maneuvers.

Engine stop switch
Push this switch 1 (red button) to stop
the engine normally.
EJU01016
Engine shut-off switch
Insert the clip 1, on the end of the engine
shut-off cord 2, under the engine shut-off
switch 3 (black button). The engine will stop
automatically when the clip is removed from
the switch, such as if the operator falls off
the watercraft.
WARNING@
Always attach the engine shut-off cord
to your wrist and the clip to the engine
shut-off switch BEFORE starting the
engine.

To prevent accidental starting of the
engine or unauthorized use by chil-
dren or others, always remove the clip
from the shut-off switch when the
engine is not running.

EJU01017
Choke lever
Starting a cold engine requires a richer
air-fuel mixture, which is supplied by the
choke.
Move the lever 1 in direction a to turn
the choke on.
Move the lever in direction b to turn the
choke off.

Bow down
Turn the grip to A or B and the bow will
go down while the watercraft is on plane.
Bow down puts more of the bow in the
water. This gives the watercraft more “hook,”
which enhances turning performance. This
position will also help the watercraft get up
on plane more quickly.
At higher speeds, however, the watercraft
will have greater tendency to “bow steer”
and follow waves and wakes in the water.
Fuel economy and maximum speed are also
reduced.
EJU01024
Bow up
Turn the grip to C or D and the bow will
go up while the watercraft is on plane.
Bow up puts less of the bow in the water.
There is less water resistance, so straight-
ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the water-
craft may tend to “porpoise” (hop in the
water). If the watercraft is porpoising,
choose neutral or bow down.
EJU01979
Handgrip
The handgrip 1 provides a handhold for
boarding the watercraft.
WARNING@ Do not use the handgrip to lift the water-
craft. The watercraft could fall, which
could result in severe injury.

Engine overheat warning
system
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the warn-
ing light and the engine overheat warning
indicator begin to blink, the buzzer sounds,
and the engine speed will be limited to about
3,400 r/min.
When this occurs, check for water dis-
charge at the cooling water pilot outlet. If
there is no discharge of water, reduce the
engine speed and beach the watercraft, and
then check the intake grate and impeller for
clogging.
WARNING@ Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
@
CAUTION:@ If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe
engine damage.
@
NOTE:@ Press the reset button on the multifunction
information center to stop the buzzer.

Fuel meter
The fuel meter is provided for convenient
fuel level checking while riding. The fuel
meter has eight segments which show the
amount of fuel remaining in the fuel tank.
NOTE:@ The indication of the segments differs on
your operating condition. Use the meter as a
reference.

EJU01032
Hour meter
The hour meter is provided to make it
easy to follow the maintenance schedule.
The meter shows the hours of engine opera-
tion that have elapsed since the watercraft
was new.
NOTE:@
The elapsed time will be kept even if the
battery terminals have been discon-
nected.

If the hour meter malfunctions, “_ _ _ _”
display and the warning light will blink.
