Safety information
12
in certain kinds of accidents and that it
could injure you in others.
A helmet is designed to provide some head
protection. Although helmets cannot pro-
tect against all foreseeable impacts, a hel-
met might reduce your injuries in a collision
with a boat or other obstacle.
A helmet may have potential safety haz-
ards, as well. Falling into the water could
risk the chance of the helmet catching wa-
ter, commonly known as “bucketing”, and
the resulting strain on your neck could cau-
se choking, severe and permanent neck in-
juries, or death. A helmet could also
increase the risk of an accident if it reduces
your vision or hearing, or if it distracts you
or increases your fatigue.
How should you decide if a helmet’s poten-
tial safety benefits outweigh its potential
risks for you? Consider your particular rid-
ing conditions. Consider factors such as
your riding environment and your riding
style and ability. Also consider the likeli-
hood of traffic congestion, and the water
surface conditions.
If you decide to wear a helmet based upon
your riding circumstances, choose one
carefully. Look for a helmet designed for
personal watercraft use, if possible. If you
will be engaging in closed-course competi-
tion, follow the helmet requirements of the
sanctioning organization.
Never operate the watercraft after consum-
ing alcohol or taking other drugs.
For reasons of safety and proper care of
the watercraft, always perform the pre-op-
eration checks listed on page 48 before op-
erating the watercraft.
The operator should grip the handlebars
firmly with both hands and the passengers
should hold on firmly, either to the person in front of them or to the handgrip provid-
ed.
The operator and passengers should al-
ways keep their feet on the floor of the foot-
well when the watercraft is in motion.
Lifting your feet increases the chances of
losing your balance,
or hitting objects out-
side the watercraft with your feet. Do not
give a ride to children if their feet cannot
reach the floor of the footwell.
Never allow a passenger to ride in front of
the operator.
Always consult your doctor on whether it is
safe for you to ride this watercraft if you are
pregnant or in poor health.
Do not attempt to modify this watercraft.
Modifications to your watercraft may re-
duce safety and reliability, and render the
watercraft unsafe or illegal for use.
Attach the engine shut-off cord (lanyard) to
y o u r l ef t w r is t an d k ee p i t fr e e f r o m t h e h an -
dlebars so that the engine stops if you, the
operator, fall off. After riding, remove the
engine shut-off cord (lanyard) from the wa-
tercraft to avoid accidental starting or un-
authorized use by children or others.

Watercraft control functionsEJU47111Engine start/stop switch “ / ”ECJ01311
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
The engine start/stop switch (red button)
starts the engine when the switch is pushed
while the engine is stopped, and stops the
engine when the switch is pushed while the
engine is running.
Release the engine start/stop switch as soon
as the engine starts to run. If the engine does
not start in 5 seconds, release the engine
start/stop switch, wait 15 seconds, and then
try again.
The engine will not start under any of the fol-
lowing conditions:
Clip is removed from the engine shut-off
switch.
Throttle lever is squeezed.
Throttle lever is malfunctioning.
RiDE lever is squeezed.
RiDE lever is malfunctioning.
EJU31164Engine shut-off switch “ ”
The engine shut-off switch automatically
stops the engine when the clip, on the end of
the engine shut-off cord (lanyard), is removed
from the switch, such as if the operator falls
off the watercraft.
Insert the clip under the engine shut-off
switch before starting the engine.
When the engine is not running, remove the
clip from the engine shut-off switch to pre-
vent accidental starting or unauthorized op-
eration by children or others.

Control function operation

The throttle lever returns automatically to its
fully closed (idle) position when released.
EJU43343RiDE lever
When the RiDE lever is squeezed, the reverse
gate lowers and the watercraft starts moving
in reverse. If the watercraft is moving forward,
the watercraft gradually slows down until it
stops, and then the watercraft starts moving
in reverse.
When the RiDE lever is released, it automati-
cally returns to its fully closed (idle) position
and the reverse gate moves to the neutral po-
sition.
EJU31263Steering system
By turning the handlebars in the direction you
wish to travel, the angle of the jet thrust noz-
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

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 84 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.
If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under thewater separator.
(2) Gradually loosen the drain screw to drain the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth.
(3) Securely tighten the drain screw until it stops.

Multifunction information center
The multifunction information center displays
various watercraft information.
Multifunction information center initial op-
eration
When the multifunction information center is
activated, all of the display segments come
on. After 2 seconds, the warning indicators in
the information display go off, and then the
center starts to operate normally.
TIP
The multifunction information center is turned
on, even if the engine start/stop switch is also
pushed briefly.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 30 sec-
onds after the engine stops, the center will
turn off and enter a standby state. When the
engine is started again, the displays return to
their state before the center turned off, and
then the center starts to operate normally.
EJU35028Information display
The information display shows watercraft op-
erating conditions.
EJU47131Speedometer
The speedometer shows the watercraft
speed.
By switching the display units, the speed can
be shown in kilometers per hour “km/h” or
miles per hour “MPH”.
TIP
“MPH” is selected as the display unit at the
Yamaha factory.
