Operating your watercraft
WARNING
EWJ00511
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
EJU32965Getting to know your watercraft
Operating your watercraft requires skills ac-
quired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneu-
vers.
Operating your new watercraft can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar-
ize yourself with the operation of the water-
craft to achieve the skill level necessary to
enjoy riding safely.
Before operating this watercraft, read this
owner’s/operator’s manual, the Riding Prac-
tice Guide, the Riding Instruction card, and all
labels on the watercraft. Pay particular atten-
tion to the safety information beginning on
page 10. These materials should give you an
understanding of the watercraft and its oper-
ation.
Remember: This watercraft is designed to
carry the operator and up to 2 passengers.
Never exceed the maximum load limit or al-
low more than 3 persons (or 2 persons if a
wakeboarder or water-skier is being pulled)
to ride the watercraft at any time.
EJU33006Learning to operate your watercraft
Before operating the watercraft, always per-
form the pre-operation checks listed on page
47. The short time spent checking the water-
craft will reward you with added safety and
reliability.
Check local laws before operating your wa-
tercraft.
Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other watercraft. Select a wide area to
learn in, where there is good visibility and
light boat traffic.
Use the buddy system—operate with some-
one nearby. Scan constantly for people, ob-
jects, and other watercraft. Be alert for
conditions that limit your visibility or block
your vision of others.
You should grip the handlebars firmly and
keep both feet on the floor of the footwell. Do
not attempt to ride with passengers until your
operating skills are fully developed.Maximum load:
240 kg (530 lb)
Load is the total weight of cargo, op-
erator, and passengers.

The operator should grip the handlebars firm-
ly with both hands and sit astride the seat
with both feet on the floor of the footwell.
Passenger riding position
The passenger(s) should hold on firmly, either
to the person in front of them or to the hand-
grip provided, and sit astride the seat with
their feet on the floor of the footwell. Never al-
low a passenger to ride in front of the opera-
tor. (See page 17 for information on the riding
position when pulling a wakeboarder or wa-
ter-skier.)
EJU32803Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles around you.
If the watercraft is launched from a trailer,
someone should make sure that waves do
not push the watercraft into the trailer.
EJU43580Starting the engine on water
WARNING
EWJ01531
Do not apply throttle when anyone is at the
rear of the watercraft. Turn the engine off
or keep it at idle. Water and debris exiting
the jet thrust nozzle can cause severe in-
jury.
To start the engine:
(1) Move the watercraft to an area that is
free from weeds and debris, and has a
water depth of at least 60 cm (2 ft) 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
pebbles or sand could be sucked into
the jet intake, causing impeller dam-
age and engine overheating.
[ECJ00473]
(2) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch. (See page
25 for information on operating the en-
gine shut-off switch.) WARNING! Check
that the engine shut-off cord (lanyard)
is attached correctly. If the engine
shut-off cord (lanyard) is not attached
correctly, it may not pull free when the
operator falls off, allowing the water-

V1 Sport:
When the shift lever is in the forward position
and the engine is running, the watercraft will
move forward. The watercraft will move for-
ward at trolling speed even if the throttle lever
is in the fully closed (idle) position. (See page28 for information on operating the shift le-
ver.)
EJU33255Turning the watercraft
WARNING
EWJ00772
Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.
When operating at higher speeds, make
gradual turns or slow down before turn-
ing. Sharp high-speed turns may cause
the watercraft to slide sideways or spin,
throwing the operator and passenger(s)
overboard, which could cause an injury.
Steering control depends on the combination
of handlebar position and the amount of
throttle.

Operation

Water sucked in through the intake grate is
pressurized by the impeller in the jet pump.
As the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.
B. Less throttle produces lower thrust, so
the watercraft will turn more gradually.
C. 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. You may still have
some turning ability immediately after re-
leasing the throttle lever, but once theengine slows down, the watercraft will no
longer respond to handlebar input until
you apply throttle again or you reach
trolling speed.
At trolling speed, the watercraft can be
turned gradually by handlebar position
alone using just the amount of thrust
available at idle.
D. If the engine is stopped while riding,
there is no thrust. The watercraft will go
straight even though the handlebars are
turned.
You need throttle to steer.
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 (see condition C above).
The OTS system assists in turning by con-
tinuing to supply some thrust while the water-
UF2P72E0.book Page 60 Tuesday, August 26, 2014 10:08 AM

Operation
61
craft is decelerating, but you can turn more
sharply if you apply throttle while turning the
handlebars. The OTS system does not func-
tion below planing speeds or when the en-
gine 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.
EJU33295Stopping the watercraft
The watercraft is not equipped with a sepa-
rate braking system. It is stopped by water
resistance when the throttle lever is released.
From full speed, the watercraft comes to a
complete stop in approximately 100 m (330
ft) after the throttle lever is released or the en-
gine is stopped, although this distance will
vary depending on many factors, including
gross weight, water surface conditions, and
wind direction. The watercraft slows down as
soon as the throttle lever is released, but will
coast for a distance before fully stopping. If
you are not sure you can stop in time before
hitting an obstacle, apply throttle and turn in
another direction.
WARNING
EWJ00745
Allow adequate stopping distance.
Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft to give you
time to stop.
Do not shut the engine off when slowing
down in case you need engine power to
steer away from a boat or other obstacle
that comes into your path.
V1 Sport: Do not use the reverse func-
tion to slow down or stop the watercraft
as it could cause you to lose control, be
ejected, or impact the handlebars.
EJU41581Operating the watercraft in reverse
(V1 Sport)
Pull the shift lever rearward to the reverse po-
sition. The watercraft will move in reverse.

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-
bles or sand could be sucked into the jet
intake, causing impeller damage and en-
gine overheating.
[ECJ00473]
TIP:
V1 Sport: This watercraft is equipped with a
reboarding step, which can be lowered and
used to assist in reboarding. (See page 35 for
information on operating the reboarding
step.)

EJU3316ABoarding with passenger(s)
WARNING
EWJ00661
Severe internal injuries can occur if water
is forced into body cavities as a result of
being near the jet thrust nozzle. Do not ap-
ply throttle until the passengers are seat-
ed with their feet on the floor of the
footwell and are securely holding on to the
person in front of them or to the handgrip
provided.
The heavier the total weight of the operator
and passenger(s), the more difficult it will be
to balance the watercraft. Do not operate the
watercraft when the total weight exceeds 240
kg (530 lb) including any cargo.To board at a standstill:
(1) Board as noted in the previous section
“Boarding alone”.
(2) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
