vary by model, the main data points are:
Engine status and engine performance
data
This data will be uploaded only when a spe-
cial Yamaha diagnostic tool is attached to the
engine, such as when maintenance checks or
service procedures are performed. Engine
data uploaded will be handled appropriately
according to the following Privacy Policy.
Privacy Policy
Yamaha will not disclose this data to a third party except in the following cases. In addi-
tion, Yamaha may provide engine data to a
contractor in order to outsource services re-
lated to the handling of the engine data. Even
in this case, Yamaha will require the contrac-
tor to properly handle the engine data we
provided and Yamaha will appropriately
manage the data.
With the consent of the boat owner
Where obligated by law
For use by Yamaha in litigation

Safety information

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.

EJU43620
Hazard information
Never start the engine or let it run for any
length of time in an enclosed area. Exhaust
fumes contain carbon monoxide, a color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.
Do not touch the hot oil tank, muffler, or en-
gine during or immediately after engine op-
eration; they can cause serious burns.
Do not place magnets or objects with a
strong magnetic force near the throttle le-
ver or RiDE lever. The electronic throttle
mechanism of the levers can be adversely
affected, which could cause loss of control.
In addition, do not place objects suscepti-
ble to magnetic forces (i.e., credit cards,
watches, etc.) close to the throttle lever or
RiDE lever.
EJU42416
Watercraft characteristics
Jet thrust turns the watercraft. Releasing
the throttle lever completely produces only
minimum thrust. If you are traveling at
speeds above trolling, you will have rapidly
decreasing ability to steer without throttle.
This model is equipped with the Yamaha
Engine Management System (YEMS) that
includes an off-throttle steering (OTS) sys-
tem. 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 sharp-
ly if you apply throttle while turning the han-
dlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the water-
craft will no longer turn in response to han-
dlebar input until you apply throttle again or
you reach trolling speed.
Practice turning in an open area without
obstacles until you have a good feel for this
maneuver.
This watercraft is water-jet propelled. The
jet pump is directly connected to the en-
gine. This means that jet thrust will produce
some movement whenever the engine is
running and the “F” (forward) or “R” (re-
verse) shift indicator is displayed. When the
“N” (neutral) shift indicator is displayed, the
forward and reverse thrust are balanced to
help keep the watercraft from moving in ei-
ther direction, although some movement
may occur.

To avoid rear-end collisions while operat-
ing the watercraft, check behind you be-
fore using the RiDE lever to slow down or
stop the watercraft. Make sure that there
are no obstacles or people behind you be-
fore shifting into reverse.
Keep away from the intake grate while the
engine is on. Items such as long hair, loose
clothing, or PFD straps can become entan-
gled in moving parts, resulting in severe in-
jury or drowning.
Never insert any object into the jet thrust
nozzle while the engine is running. Severe
injury or death could result from coming in
contact with the rotating parts of the jet
pump.
Stop the engine and remove the clip from
the engine shut-off switch before removingany debris or weeds, which may have col-
lected around the jet intake.

Enjoy your watercraft responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility
to treat these other people, and the lands,
waters, and wildlife with respect and courte-
sy.
Whenever and wherever you ride, think of
yourself as the guest of those around you.
Remember, for example, that the sound of
your watercraft may be music to you, but it
could be just noise to others. And the exciting
splash of your wake can make waves others
won’t enjoy.
Avoid riding close to shoreline homes and
waterfowl nesting areas or other wildlife ar-
eas, and keep a respectful distance from fish-
ermen, other boats, swimmers, and
populated beaches. When travel in areas like
these is unavoidable, ride slowly and obey all
laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within reg-
ulated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, pollution can be harmful to the
environment. Do not refuel or add oil where a
spill could cause damage to nature. Remove
your watercraft from the water and move it
away from the shoreline before refueling. Dis-
pose of water and any fuel and oil residue in
the engine compartment according to local
regulations. And keep your surroundings
pleasant for the people and wildlife that share
the waterways: don’t litter. When you ride responsibly, with respect and
courtesy for others, you help ensure that our
waterways stay open for the enjoyment of a
variety of recreational opportunities.
