Leaving the watercraft
If leaving the watercraft, select the lock
mode of the Yamaha Security System (for
VX110 Deluxe) and remove the engine shut-
off cord to reduce the chance of accidental
starting or unauthorized use by children or
others. (See page 2-15 for Yamaha Security
System and low-RPM mode selection pro-
cedures.)

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 passengers 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
the passenger 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.
Never allow a passenger to ride in front
of the operator.
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.

Transporting
When transporting the watercraft on a
trailer, secure the tie downs to the trailer
through the bow eye and stern eyes.
CAUTION:@
Do not use any projections other than
the bow eye and stern eyes to secure
the watercraft to the trailer. Otherwise,
the watercraft may be damaged.

Do not route ropes or tie downs over
the seat, as they may leave permanent
marks on the seat’s surface. Also,
wrap the ropes or tie downs with tow-
els or rags where they touch the body
of the watercraft to avoid scratches or
damage.

For VX110 Deluxe:
Before putting the watercraft on the
trailer or transporting it, be sure to put
the shift lever in the forward position,
otherwise the reverse gate may hit an
obstruction, which may cause dam-
age.

1. Put the watercraft on land in a horizontal
position.
2. Remove the seat. (See page 2-5 for seat
removal and installation procedures.)
3. Remove the flushing hose connector
cap1, and then insert the garden hose
adapter 2 into the flushing hose con-
nector 3 and turn it until it is securely
connected.
4. Connect the garden hose adapter to a
water tap using a hose.
NOTE:@ The garden hose is not included and must
be purchased separately.
@
5. Start the engine, and then immediately
turn the water supply on until water flows
out continually from the jet nozzle.
6. Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
repeat the above steps.
7. Turn the water supply off, and then force
the remaining water out from the cooling
water passages by alternately squeezing
and releasing the throttle lever for 10 to
15 seconds.
8. Stop the engine.
9. Remove the garden hose adapter and
install the cap.

Fuel system
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.

Stop engine before refueling.

Refuel in a well-ventilated area with
the watercraft in a horizontal position.

Do not stand or sit on the watercraft
while refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level reaches approx-
imately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do
not leave it in direct sunlight. Leave it
in a well-ventilated area with the water-
craft in a horizontal position.

Tighten the filler cap securely after
refueling.

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
Top off the fuel tank with fresh gasoline
and add fuel stabilizer and conditioner to the
fuel tank by following the manufacturer’s
instructions carefully.

Measure the spark plug gap a with a
wire thickness gauge. Replace the spark
plug or adjust the gap to specification if nec-
essary.
To install a spark plug:
1. Clean the gasket surface.
2. Wipe any dirt from the threads of the
spark plug.
3. Install the spark plug, and then tighten it
to specification.
4. Install the spark plug cap.
NOTE:@
Wipe off any water on the spark plug or
inside the spark plug cap before installing
the cap. Push the spark plug cap down
until it is securely installed.

If a torque wrench is not available when
you are installing a new spark plug, a
good estimate of the correct torque is 1/4
turn to 1/2 turn past finger tight with the
spark plug wrench included in the tool kit.
Have the spark plug adjusted to the cor-
rect torque with a torque wrench as soon
as possible.
@
WARNING@ Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks
to escape, which could lead to an explo-
sion or fire.
@
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)
Spark plug tightening torque:
12.5 N·m (1.25 kgf·m, 9 ft·lb)

Inspecting the battery
Check the level of the battery electrolyte
and make sure that the negative and posi-
tive leads are securely tightened.
WARNING@
Battery electrolyte is poisonous and
dangerous, causing severe burns, etc.
Electrolyte contains sulfuric acid.
Avoid contact with skin, eyes, or cloth-
ing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg, or vegetable oil. Call phy-
sician immediately.
Eyes: Flush with water for 15 minutes
and get prompt medical attention.
Batteries produce explosive gases.
Keep sparks, flame, cigarettes, etc.,
well away. If using or charging the bat-
tery in an enclosed space, make sure
that it is well ventilated. Always shield
your eyes when working near batter-
ies.
KEEP OUT OF THE REACH OF CHIL-
DREN.

Be sure to connect the breather hose
to the battery. Fire or explosion could
result if the breather hose is damaged,
obstructed, or not connected properly.
@
CAUTION:@
Be careful not to place the battery on
its side.

Be sure to remove the battery from the
battery compartment when adding
electrolyte or charging the battery.

To replenish the battery:
1. Make sure that the electrolyte level is
between the upper 1 and lower 2 level
marks.
2. Refill the battery with distilled water if
necessary.
CAUTION:@ Normal tap water contains minerals that
are harmful to a battery. Use only dis-
tilled water for replenishing the battery.
@
To recharge the battery:
CAUTION:@ Do not attempt to charge a battery hast-
ily. Battery life could be shortened.
@
It is recommended to have a Yamaha
dealer charge the battery. If you charge the
battery yourself, carefully read the battery
charger instructions before charging and fol-
low the points below.
1. Remove all caps from the battery cell.
2. Add distilled water to the specified level if
the electrolyte level is low.
3. Set the charging rate to 1.9 ampere and
charge the battery slowly until the explo-
sive gases are discharged vigorously
from the battery cells.
To connect the battery terminals:
1. Make sure that the connections are cor-
rect when you install the battery in the
watercraft.
2. Make sure that the breather hose is
properly connected and that it is not
damaged or obstructed.
3. Make sure that the battery is securely
held in place.

than those recommended. Substitution
with a fuse that has an improper rating
can cause extensive electrical system
damage and possible fire.
