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 muffler or engine dur-
ing or immediately after engine operation;
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.
EJU42414
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 in the
multifunction display. When the “N” (neu-
tral) shift indicator is displayed, the forward
and reverse thrust are balanced to help
keep the watercraft from moving in either

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 removing
any debris or weeds, which may have col-
lected around the jet intake.

Wakeboarding and water-
skiing
You can use the watercraft for wakeboarding
or water-skiing if it has the seating capacity to
carry the operator, a rearward-facing spotter,
and the wakeboarder or water-skier when he
or she is not being pulled.
The watercraft must also have a cleat de-
signed to pull a ski rope; do not attach the
rope to any other location.
It is the watercraft operator’s responsibility to
be alert to the safety of the wakeboarder or
water-skier and others. Know and follow all
local regulations in effect for the waters in
which you will be operating.
The operator should be comfortable carrying
passengers before attempting to pull a wake-
boarder or water-skier.
The following are some important consider-
ations for minimizing risks while pulling a
wakeboarder or water-skier.
The wakeboarder or water-skier should
wear an approved PFD, preferably a bright-
ly colored one so boat operators can see
the person being pulled.
The wakeboarder or water-skier should
wear protective clothing. Severe internal in-
juries can occur if water is forced into body
cavities as a result of falling into the water.Normal swimwear does not adequately
protect against forceful water entry into the
rectum or vagina. The person being pulled
should wear a wetsuit bottom or clothing
that provides equivalent protection.
A second person should be on board as a
spotter to watch the wakeboarder or wa-
ter-skier; in many places it is required by
law. Let the person being pulled direct the
operator’s control of speed and direction
with hand signals.
The spotter should sit astride the rear of the
seat and hold onto the handgrip with both
feet firmly on the floor of the footwell for
proper balance while facing to the rear to
watch the wakeboarder’s or water-skier’s
hand signals and condition.
Your control while pulling a wakeboarder or
water-skier is affected by the wakeboard-

er’s or water-skier’s ability, as well as water
and weather conditions.
When preparing to pull a wakeboarder or
water-skier, operate the watercraft at the
slowest possible speed until the watercraft
is well away from the person being pulled
and slack in the ski rope is taken up. Make
sure that the rope is not looped around
anything.
After checking that the wakeboarder or wa-
ter-skier is ready and that there is no traffic
or other obstacles, apply enough throttle to
raise the person.
Make smooth, wide turns. The watercraft is
capable of very sharp turns, which could
exceed the abilities of the wakeboarder or
water-skier. Keep the person being towed
at least 50 m (164 ft), about twice the dis-
tance of a standard ski rope, away from
any potential hazard.
The operators of boats and other water-
craft may not be aware that you are pulling
a wakeboarder or water-skier. Together
with the spotter, pay attention to others
around you and cruise at safe speeds.
Be alert to the hazard of the ski rope handle
snapping back at the watercraft when the
wakeboarder or water-skier falls or is un-
able to get up.
Towing heavy or bulky objects other than
wakeboarders or water-skiers, such as an-
other boat or watercraft, can cause loss of
steering control and create a hazardous
condition. If you must tow another boat in
an emergency situation, operate slowly
and cautiously.
EJU30971
Safe boating rules
Your Yamaha watercraft is legally considered
a powerboat. Operation of the watercraft
must be in accordance with the rules and
regulations governing the waterway on which
it is used.

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.
