Safety information
13

Always consult your doctor on whether it is
safe for you to ride this watercraft if you are
pregnant or in poor health.

Do not attempt to modify this watercraft!
Modifications to your watercraft may reduce
safety and reliability, and render the water-
craft unsafe or illegal for use.

Attach the engine shut-off cord to your left
wrist and keep it free from the handlebars
so that the engine stops if you, the operator,
fall off. After riding, remove the engine shut-
off cord from the watercraft to avoid acci-
dental starting or unauthorized use by chil-
dren or others.

Scan carefully for swimmers and stay away
from swimming areas. Swimmers are hard
to see and you could accidentally hit some-
one in the water.

Avoid being hit by another boat! You should
always take the responsibility to watch for
traffic; other boaters may not be watching
for you. If they do not see you, or if you ma-
neuver more quickly than other boaters ex-
pect, you risk a collision.

Maintain a safe distance from other boats
and watercraft, and also watch for ski ropes
or fishing lines. Obey the “Safe boating
rules” and be sure to check behind you be-
fore making a turn. (See “Safe boating
rules” on page 17.)
EJU30840
Recommended equipment
The following items should be carried on
board your watercraft:

Sound-signaling device
You should carry a whistle or other sound-
signaling device that can be used to signal
other boats.

Visual distress signals
It is recommended that a pyrotechnic de-
vice, which is approved by the appropriate
authorities, be stored in a waterproof con-
tainer on your watercraft. A mirror can also
be used as an emergency signal. Contact a
Yamaha dealer for more information.

Watch
A watch is helpful so you will know how long
you have been operating the watercraft.

Towline
A towline can be used to tow a disabled wa-
tercraft in an emergency.

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 oil tank, muffler, or en-
gine during or immediately after engine op-
eration; they can cause serious burns.
EJU30930
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 re-
leasing the throttle lever. The OTS system
assists in turning by continuing to supply
some thrust while the watercraft is deceler-
ating, 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.
Practice turning in an open area without ob-
stacles until you have a good feel for this
maneuver.

This watercraft is water-jet propelled. The
jet pump is directly connected to the engine.
This means that jet thrust will produce some
movement whenever the engine is running.
There is no “neutral” position. You are in ei-
ther “forward” or “reverse”, depending upon
the shift lever position (for VX Deluxe/VX
Cruiser).

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 im-
pact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and broken

legs, ankles, and other bones. You could
also damage the shift mechanism.

For VX Deluxe/VX Cruiser:
Reverse can be used to slow down or stop
during slow-speed maneuvering, such as
when docking. Once the engine is idling,
shift into reverse and gradually increase en-
gine speed. Make sure that there are no ob-
stacles or people behind you before 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 removingany debris or weeds, which may have col-
lected around the jet intake.
