EJU33092Boarding and starting in shallow water
(1) Launch 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 operate 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.

tions before starting off.
EJU36081Boarding and starting in deep water
WARNING
EWJ01111
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 expo-
sure, increasing the risk of injury and
drowning.
Boarding in deep water requires more skill.
The operator and passengers should practice
boarding in shallow water before riding in
deep water.

(1) Swim to the rear of the watercraft and
place both hands on the boarding plat-
form, pull yourself up, and then grasp the
handgrip with one hand.
(2) Pull yourself up to a kneeling position on
the platform, and then move to the seat
and sit astride.
(3) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch.
(4) Grip the handlebars with both hands,
place both feet on the floor of the footwell,start the engine, and then look in all direc-
tions before starting off.
TIP:
If your watercraft is equipped with the re-
boarding step (for VX Cruiser), you can lower
the step to make reboarding easier. The step
returns automatically to the up position after
you have boarded.
EJU33164Boarding with passengers
WARNING
EWJ00660
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 seated
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 provid-
ed.
TIP:
The heavier the total weight of the operator
and passengers, 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 your left wrist, and then attach the clip
to the engine shut-off switch.
(3) Have the passengers move to the rear of
the watercraft.
(4) Have a passenger board and sit astride
the seat. If a second passenger is board-
ing, have him or her follow the same pro-
cedure. When a passenger is boarding,both the passengers and the operator
should try to balance the watercraft.
(5) Check that the passengers have 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. Nev-
er allow a passenger to ride in front of the
operator.

onto the boarding platform into a kneeling
position, then move to the seat and sit
astride to balance the watercraft.
(3) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch.
(4) Start the engine and keep it at idle.
(5) Have the second passenger pull him or
herself up onto the boarding platform into
a kneeling position, then crawl onto the
seat as the watercraft accelerates.(6) Gradually increase the speed to balance
the watercraft.
EJU33231Capsized watercraft
WARNING
EWJ00671
Improper uprighting can cause injury.

Be sure to shut the engine off by pulling
on the engine shut-off cord (lanyard) to
remove the clip from the engine shut-off
switch.

Do not put your hands in the intake
grate.
If the watercraft capsizes, turn it over immedi-
ately.
Be sure to carefully follow the procedures be-
low to prevent injury, or damage to the water-
craft.
(1) Remove the clip from the engine shut-off
switch.
(2) Swim to the rear of the watercraft. Pull the
watercraft over with your left hand on the
ride plate while pushing down on the gun-
wale with your right hand or foot.
If the port (left) side of the capsized wa-
tercraft is tilting up, push down on the
gunwale so that the port (left) side is
down before turning the watercraft clock-
wise. NOTICE: Do not turn the water-
craft over counterclockwise,
otherwise water can enter the engine,

which can result in severe damage.
[ECJ00541]
(3) Start the engine and operate the water-
craft as straight as possible and above
planing speed for at least 2 minutes to
discharge any water remaining in the en-
gine compartment. (If the engine does
not start, see “Towing the watercraft” on
page 80 or “Submerged watercraft” on
page 80.) NOTICE: Do not operate the
engine at full throttle for at least 1
minute after the engine has been re-
started. Excessive water in the engine
compartment can splash into the en-
gine, which can result in severe dam-
age.

EJU33251
Turning the watercraft
WARNING
EWJ00770

Do not release the throttle lever when
trying to steer away from objects—youneed 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 passengers
overboard, which could cause an injury.
Steering control depends on the combination
of handlebar position and the amount of throt-
tle.
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.
UF2L70E0.book Page 57 Thursday, June 19, 2008 8:38 AM

Operation
58
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 releasing
the throttle lever, but once the engine
slows down, the watercraft will no longer
respond to handlebar input until you ap-
ply 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 continu-
ing to supply some thrust while the watercraft
is decelerating, but you can turn more sharply
if you apply throttle while turning the handle-
bars. The OTS system does not function be-
low planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar in-
put until you apply throttle again or you reach
trolling speed.
EJU33280Stopping the watercraft
The watercraft is not equipped with a sepa-
rate braking system. It is stopped by water re-
sistance 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.
UF2L70E0.book Page 58 Thursday, June 19, 2008 8:38 AM

Operation
59
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 ob-
stacle, apply throttle and turn in another direc-
tion.
WARNING
EWJ00730

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.

For VX Deluxe/VX Cruiser:
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.
EJU35961Beaching the watercraft
(1) Make sure that there are no boats, swim-
mers, or obstacles near the beach. Re-
lease the throttle lever about 100 m (330ft) before you reach the intended beach-
ing area.
(2) Approach the beach slowly and stop the
engine before reaching land.
Remember, you need throttle to steer.
(3) Get off the watercraft and pull it up on the
beach. NOTICE: Small pebbles, sand,
seaweed, and other debris can be
sucked into the jet intake and impair
or damage the impeller. Always stop
the engine and get off the watercraft
before beaching it.
[ECJ00491]
EJU36060
Docking the watercraft
(1) Make sure that there are no boats, swim-
mers, or obstacles near the watercraft.
Reduce speed about 100 m (330 ft) away
from the dock.
(2) Slowly approach the dock and stop the
engine just before coming alongside it.
EJU33321Reverse on waterways (for VX
Deluxe/VX Cruiser)
Reverse can be used for slow-speed maneu-
vering when it is necessary to back up out of
tight spots where you cannot turn around.
Once the engine is idling, shift into reverse
and gradually increase engine speed. Make
sure that there are no obstacles or people be-
hind you before shifting into reverse.

EJU37190Operating in weeded areas
Always avoid operating your watercraft in ar-
eas where weed growth is thick. If traveling in
weeded areas is unavoidable, operate the en-
gine alternately at partial throttle and full throt-
tle. Weeds tend to accumulate more at a
steady speed and at trolling speed. If weeds
clog the intake area and cause cavitation,
clean the jet intake and impeller. (See page
78 for cleaning procedures.)
EJU33382
Post-operation care
To keep your watercraft in top shape, always
take it out of the water after using it and per-
form the following procedures. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deterioration
of the jet unit components and hull finish. Ma-
rine organisms and corrosion are some of the
conditions that can adversely affect the life of
many watercraft components.
(1) Remove the watercraft from the water.
(2) Wash down the hull, handlebars, and jet
unit with fresh water.
(3) Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow the water in the bilge to
drain out.
TIP:
This watercraft is equipped with an automatic
bilge draining system that removes water
from the engine compartment while you are
underway. However, some residual water will
remain, therefore remove the stern drain
plugs to drain the water. (See page 43 for
bilge draining procedures.)
(4) Place the watercraft in a horizontal posi-
tion.
