Battery
Check the battery condition and the elec-
trolyte level.
Check that the battery leads are tightened
securely and there is no corrosion on the
battery terminals.
WARNING@
The battery must always be fully
charged and in good condition. Loss
of battery power may leave you
stranded. Never operate the watercraft
if the battery does not have sufficient
power to start the engine or if it shows
any other signs of decreased power.

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.
@
Make sure that the battery is securely
held in place.

Fire extinguisher
Check that there is a full fire extinguisher
on board. The fire extinguisher holder and
cover 1 are located in the front storage
compartment.
To store the fire extinguisher, unhook the
band 2 and remove the cover. Place the fire
extinguisher in the holder, and then place
the cover over the fire extinguisher. Fasten
the cover and the fire extinguisher with the
band securely.
NOTE:@
See the instructions supplied by the fire
extinguisher manufacturer for checking
the fire extinguisher. Always keep the
extinguisher secured in the holder with its
cover in place.

Always carry a fire extinguisher on board.
A fire extinguisher is not standard equip-
ment with this watercraft. If you do not
have one, contact a Yamaha dealer or a
fire extinguisher dealer to obtain one
meeting the proper specifications.

Throttle
Squeeze and release the throttle lever
several times to make sure that there is no
hesitation in its travel. It should be smooth
over the complete range, and spring back to
the idle position when released.
WARNING@ Before starting the engine, always check
the operation of the throttle lever.

Steering system
Check for looseness in the handlebars.
Turn them as far as possible to the right
and left to make sure that operation is
smooth and unrestricted throughout the
whole range. Make sure that the jet thrust
nozzle also changes directions as the han-
dlebars are turned, and that there is no free
play between the handlebars and the jet
thrust nozzle.
EJU12451
Shift lever and reverse gate
(for VX110 Deluxe)
Check for proper operation of the shift
lever and reverse gate.
Make sure that the reverse gate goes
down completely when the shift lever is
pulled up.
Also, make sure that the reverse gate
goes up completely when the shift lever is
pushed down.
WARNING@
Make sure that the throttle is com-
pletely released and that the engine is
at idle before shifting into reverse.

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.

Use reverse for slow-speed maneuver-
ing only.

Make sure that there are no obstacles
or people behind you before shifting
into reverse.

Do not touch the reverse gate while the
shift lever is being operated, otherwise
you could be pinched.

Jet unit
Carefully check the jet intake for weeds,
debris, or anything else that might restrict
the intake of water. If the intake is clogged,
cavitation could occur, reducing jet thrust,
and possibly damaging the jet pump.
In some cases, the engine may overheat
because of lack of cooling water, and dam-
age to the engine could result. Engine cool-
ing water is fed to the engine by the jet
pump. (See page 5-3 for jet intake cleaning
procedures.)
WARNING@
Keep away from intake grate while
engine is on. Items such as long hair,
loose clothing, or PFD straps can
become entangled in moving parts
resulting in severe injury or drowning.

Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds, which
may have collected around the jet
intake.

EJU10590
Engine shut-off cord (lanyard)
Check that the engine shut-off cord is not
frayed or broken. If the cord is damaged,
replace it; never try to repair it or tie it
together.

Switches
CAUTION:@ Do not run the engine of the watercraft
for more than 15 seconds on land with-
out supplying water, otherwise the
engine may overheat.
@
Check the start switch, the engine stop
switch, and the engine shut-off switch for
proper operation.
Push the start switch 1 to start the
engine. As soon as the engine starts run-
ning, push the engine stop switch 2 to ver-
ify that the engine stops immediately.
Restart the engine, and then pull the engine
shut-off cord 5 to remove the clip 4 from
the engine shut-off switch 3 to verify that
the engine stops immediately. (See pages
2-9 to 2-10 for information on proper opera-
tion of the start switch, the engine stop
switch, and the engine shut-off switch.)

Cooling water pilot outlet
Check that water comes out from the pilot
outlet while the engine is running and the
watercraft is in the water. (See page 2-11 for
more information.)

Operation
WARNING@ Before operating your watercraft,
become familiar with all controls. Con-
sult your Yamaha dealer about any con-
trol or function you do not fully
understand. Failure to understand how
controls work could cause an accident or
prevent you from avoiding an accident.
@
CAUTION:@ Make sure that the stern drain plugs are
securely tightened before launching the
watercraft.
@
EJU18072
Engine break-in
The engine break-in period is essential to
allow the various components of the engine
to wear and polish themselves to the correct
operating clearances. This ensures proper
performance and promotes longer compo-
nent life.
CAUTION:@ Be sure to check the engine oil level
before operating the watercraft for the
first time. (See page 3-7 for engine oil
checking procedures.)
@
1. Launch the watercraft and start the
engine. (See page 3-17 for engine start-
ing procedures.)

2. For the first 5 minutes, run the engine at
trolling speed only. For the 30 minutes of
operation after that, keep the engine
speed below 5,000 r/min. For the 1 hour
of operation after that, keep the engine
speed below 6,500 r/min.
3. Proceed with normal operation.
CAUTION:@ Failure to follow the engine break-in pro-
cedure could result in reduced engine
life or even severe engine damage.

Launching the watercraft
When launching the watercraft, make
sure that there are no obstructions around
you.
If there are waves, someone should make
sure that the watercraft is not pushed into
the trailer after launching the watercraft.

For VX110 Deluxe
Use the remote control transmitter to
select the unlock mode. (See page 2-16
for Yamaha Security System and
low-RPM mode selection procedures.)
After the watercraft is in the water, start
the engine. Shift into reverse and slowly
move away from the launching area.

For VX110 Sport
After the watercraft is in the water, turn it
around so the bow faces the direction you
want to go. Start the engine, and then
slowly move away from the launching
area.

Starting the engine
WARNING@ Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monox-
ide, a colorless, odorless gas that may
cause loss of consciousness and death
within a short time. Always operate the
watercraft in an open area.
@
1. If the lock mode of the Yamaha Security
System is selected (for VX110 Deluxe),
use the remote control transmitter to
select the unlock mode. (See page 2-15
for Yamaha Security System and low-
RPM mode selection procedures.)
2. Launch the watercraft in water free from
weeds and debris and at least 60 cm
(2 ft) deep.
WARNING@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged
object, which could result in injury.
@
CAUTION:@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise pebbles or
sand could be sucked into the jet intake,
causing impeller damage or engine over-
heating.
