EJU40211Riding position
Operator riding position
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 18 for information on the riding
position when pulling a water-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.
EJU36346Starting 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) If the lock mode is selected for theYamaha Security System setting, selectthe unlock mode. (See page 27 for
Yamaha Security System setting proce- dures.)
(2) 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]
(3) Attach the engine shut-off cord (lanyard) to your left wrist, and then attach the clip
to the engine shut-off switch. (See page
28 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-
craft to continue to run and cause an
accident.
[EWJ00582]
(4) With the throttle lever released, push thestart switch (green button) to start the
engine. (See page 28 for information on
operating the start switch.)
EJU32863Stopping the engine
Release the throttle lever, and then push the
engine stop switch (red button) to stop the
engine. WARNING! You need throttle to
steer. Shutting the engine off can cause
you to hit an obstacle you are attempting to avoid. A collision could result in severe
injury or death.
[EWJ00602]
EJU32873
Leaving the watercraft
If leaving the watercraft, remove the clip from
the engine shut-off switch to prevent acci-
dental starting or unauthorized operation by
children or others.
EJU40222Operating the watercraft
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 page

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.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 the

engine 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- 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.
EJU42660Stopping 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 125 m (410
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.

Operation
72
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.
Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or
impact the handlebars.
EJU40372Operating the watercraft in reverse
Pull the shift lever rearward to the reverse po-
sition. The watercraft will move in reverse.
(See page 32 for information on the reverse
system.)Make sure that there are no obstacles or peo-
ple behind you before shifting into reverse.
TIP:
This model is equipped with a function which
limits the engine speed 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:
This watercraft is equipped with a reboarding
step, which can be lowered and used to as-
sist in reboarding. (See page 42 for informa-
tion 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.
