(subnormal body temperature) and abra-
sions.
Footwear and gloves are recommended.
Eye protection is recommended to keep wind,
water, and glare from the sun out of your eyes
while you operate your watercraft. Restraining
straps for eyewear are made which are de-
signed to float should your eyewear fall in the
water.
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.
EJU33061Riding with passengers
WARNING
EWJ00541

Do not apply throttle when anyone is at
the rear of the watercraft. Turn the en-
gine off or keep it at idle. Water and de-
bris exiting the jet thrust nozzle can
cause severe injury. Passengers should
not attempt to board the watercraft if the
operator is applying throttle.

When passengers are on board, make
sure that they are holding on firmly and
have their feet on the floor of the foot-
well before you start to accelerate.
When 2 or 3 persons (including the operator)
are on board, the watercraft handles different-
ly, and is not as easy to maneuver, therefore
operating it requires a higher degree of skill.
Before attempting to operate the watercraft
with passengers on board, the operator must
practice operating the watercraft alone
enough to be able to acquire the necessary
skills.
The passengers must always wear a PFD
that is approved by the appropriate authorities
and a wetsuit bottom or equivalent.Do not give a ride to children whose feet can-
not reach the floor of the footwell. The pas-
sengers should hold on firmly, either to the
person in front of them or to the handgrip pro-
vided, and keep their feet on the floor of the
footwell. Never allow a passenger to ride in
front of the operator.
When pulling a water-skier, the spotter should
face to the rear while holding the handgrip
with both hands. The spotter should always sit
astride the seat with both feet placed firmly on
the floor of the footwell for proper balance.
Follow all local laws regarding water-skiing,
such as those for skier-down flags, rearward-
facing spotter, and other requirements.
EJU33081Starting the watercraft
WARNING
EWJ00711
To avoid collisions:

Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vi-
sion of others.

Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.

Do not follow directly behind watercraft
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 submerged objects or shal-
low water.

Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes. Do not release the

tion, and then move to the seat and sit
astride to balance the watercraft.
(2) Have a passenger pull him or herself up
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,

If the steering is stiff or misadjusted, have a
Yamaha dealer service it.
EJU34350Checking the shift cable (for VX
Deluxe/VX Cruiser)
Place the shift lever in the reverse position.
Make sure that the reverse gate makes con-
tact with the stopper.If the reverse gate does not make contact with
the stopper, have a Yamaha dealer service it.
EJU36640Checking and adjusting the throttle
cable
Check that the throttle cable moves back to
the set position smoothly and that the throttle
lever free play is within specification.
Squeeze and release the throttle lever. If the
throttle lever does not return smoothly, have a
Yamaha dealer service it.
If the specified throttle lever free play cannot
be obtained as described below, have a
Yamaha dealer make the adjustment.
(1) Remove the six screws, and then remove
the front handlebar cover.
(2) Slide the rubber cover away from the ad-
juster, and then loosen the locknut. Difference of A and B:
Maximum 5 mm (0.20 in)

(3) Adjust the free play by turning the adjust-
er.
(4) Hold the adjuster with one wrench while
tightening the locknut with another
wrench. Slide the rubber cover to its orig-
inal position.
(5) Install the front handlebar cover, and then
install the six screws.
EJU34392Cleaning and adjusting the spark
plugs
WARNING
EWJ00350
Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks to
escape, which could result in a fire or ex-
plosion.
The spark plug is an important engine compo-
nent and is easy to inspect. The condition of
the spark plug can indicate something about
the condition of the engine. For example, if
one spark plug has a distinctly different color,
the engine could require servicing. Do not at-tempt to diagnose any problems yourself.
Have a Yamaha dealer service the watercraft.
Remove and inspect the spark plugs periodi-
cally; heat and deposits will cause the spark
plugs to slowly break down and erode. If elec-
trode erosion becomes excessive, or if carbon
and other deposits are excessive, replace the
spark plug with the specified plug.
To remove a spark plug:
(1) Remove the seat. (See page 23 for seat
removal and installation procedures.)
(2) Remove the spark plug cap. NOTICE:
Do not use any tools to remove or in-
stall the spark plug cap, otherwise the
ignition coil coupler could be dam-
aged. The spark plug cap may be diffi-
cult to remove because the rubber
seal on the end of the cap fits tightly.
To remove the spark plug cap, simply
twist it back and forth while pulling it
up; to install it, twist it back and forth
while pushing it down.
[ECJ00211]
(3) Remove the spark plug.
Measure the spark plug gap with a wire
thickness gauge. Replace the spark plug
or adjust the gap to specification if neces-
sary.
