Starting the watercraft
WARNING@ Scan constantly for people, objects,
and other watercraft. Be alert for con-
ditions that limit your visibility or block
your vision of others.
Operate defensively at safe speeds
and keep a safe distance away from
people, objects, and other watercraft.
Do not follow directly behind water-
craft or other boats. Do not go near
others to spray or splash them with
water. Avoid sharp turns or other
maneuvers that make it hard for others
to avoid you or understand where you
are going. Avoid areas with sub-
merged objects or shallow water.
Take early action to avoid collisions.
Remember watercraft and other boats
do not have brakes. Do not release the
throttle when trying to steer away from
objects—you need throttle to steer.
Practice reboarding in shallow water
before riding in deep water.

Boarding and starting in deep
water
WARNING@ Operator and passenger should prac-
tice getting on board in shallow water
before riding in deep water. Boarding
in deep water requires more skill.
The fatigue and exposure that could
result after unsuccessful attempts to
get back on the watercraft may
increase the risk of injuries and drown-
ing.
@
EJU18380
Boarding alone
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 to your
left wrist, and then install the clip to the
engine shut-off switch.
4. Grip the handlebars firmly with both
hands, place both feet on the floor of the
footwell, start the engine, and then look
in all directions before starting off.
WARNING@ Before starting off, make sure that there
are no boats, obstructions, or swimmers
around you.

Boarding with passengers
WARNING@ Severe internal injuries can occur if
water is forced into body cavities as a
result of being near the jet thrust nozzle.
Do not apply throttle until the passen-
gers 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 provided.
@
1. Climb on board as noted in the previous
section, and sit astride the seat. Attach
the engine shut-off cord to your left wrist,
and then install the clip to the engine
shut-off switch.
2. Have the passenger move to the rear of
the watercraft.
3. Have the passenger get on board and sit
on the seat. If a second passenger is
getting on, have him or her follow the
same procedure.
NOTE:@ When a passenger is getting on board, both
he and the operator should try to balance
the watercraft.
@
4. The operator should check to see that
the passengers have their feet on the
floor of the footwell and that they are
securely holding on to the person in front
of them or to the handgrip provided.
5. Start the engine, look in all directions,
and then accelerate to planing speed.
WARNING@ Before starting off, make sure that there
are no boats, obstructions, or swimmers
around you.

Capsized watercraft
If the watercraft capsizes, turn it over
immediately.
Be sure to carefully follow the procedures
below to prevent injury or damage to the
watercraft.
WARNING@ IMPROPER UPRIGHTING CAN CAUSE
INJURY:
Make sure that the engine shut-off
cord is removed from the engine shut-
off switch.
Do not put your hands in the intake
grate.
Watch so you are not hit by the water-
craft as it comes over.
@
CAUTION:@ If the watercraft capsizes, release the
throttle lever immediately. Oil could flow
into the air filter case and the engine
could be damaged.
@
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
gunwale with your right hand or foot.
NOTE:@ If the port (left) side of the capsized water-
craft is tilting up, push down on the gunwale
so that the port (left) side is down before
turning the watercraft clockwise.
@
CAUTION:@ Do not turn the watercraft over counter-
clockwise, otherwise water can leak into
the engine, which can result in severe
damage.

WARNING@ 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 turning. Sharp high-speed turns
may cause the watercraft to slide side-
ways or spin, throwing the operator
and passengers overboard which
could cause an injury.
@
This model has the Yamaha Engine Man-
agement System (YEMS) that includes an
Off-Throttle Steering (OTS) system. It will
activate at planing speeds should you
attempt to steer the watercraft after releas-
ing the throttle lever (see condition C
above). The OTS system assists in turning
by continuing to supply some thrust while
the watercraft is decelerating, but you can
turn more sharply if you apply throttle while
turning the handlebars. The OTS system
does not function below planing speeds or
when the engine 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.

Stopping the watercraft
The watercraft is not equipped with a sep-
arate 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 is released or
the engine is stopped, although this dis-
tance will vary depending on many factors,
including gross weight, water surface condi-
tions, 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@ Allow adequate stopping distance.
Take early action to avoid collisions.
Remember, 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 slow-
ing down in case you need engine
power to steer away from a boat or
other obstacle that comes into your
path.
For VX110 Deluxe:
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.

Storage
WARNING@ Always place the watercraft upright in a
horizontal position when storing it, oth-
erwise fuel could leak out into the engine
or engine compartment, which could
result in a fire hazard.
@
Storage for prolonged periods of time,
such as winter storage, requires preventa-
tive maintenance to ensure against deterio-
ration. It is advisable to have the watercraft
serviced by a Yamaha dealer prior to stor-
age. However, the following procedures can
be performed by the owner.
EJU21260
Flushing the cooling system
Flushing the cooling system is essential
to prevent the cooling system from being
clogged with salt, sand, or dirt.
CAUTION:@ Do not supply water to the cooling
water passages when the engine is not
running. The water could flow back
through the muffler into the crankcase
causing severe engine damage.
Do not run the engine of the watercraft
for more than 15 seconds without sup-
plying water, otherwise the engine may
overheat.

Lubrication
WARNING@ Do not spray flammable rust inhibitor
products on engine surfaces while the
engine is hot. The sprayed substance or
propellants could catch fire.
@
1. Remove the seat. (See page 2-5 for seat
removal and installation procedures.)
2. Loosen the clamp screw 1 and discon-
nect the air intake duct 2.
3. Spray a rust inhibitor into the intake
opening 3 for 3 seconds.
4. Connect the air intake duct and tighten
the clamp screw.
5. Start the engine in a well-ventilated area
and let it run at idle for 15 seconds.
CAUTION:@ Do not run the engine for more than
15 seconds. The engine could overheat.
@
6. Lubricate all cables such as the throttle
and steering cables.
NOTE:@ Use a suitable marine grease applicator to
pressure lubricate the cables and purge out
any moisture between the inner and outer
cables.
@
7. Lubricate the areas of the watercraft
specified under Lubrication points on
page 4-17.
