Check the start switch, the engine stop
switch, and the engine shut-off switch for
proper operation. (See pages 27 to 27 for in-
formation on operating each switch.) To check the operation of the switches:
(1) VX Deluxe / VX Cruiser: If the lock mode
is selected for the Yamaha Security Sys-
tem setting, select the unlock mode. (See
page 26 for Yamaha Security System
setting procedures.)
(2) Push the start switch to make sure that the engine starts.
(3) As soon as the engine starts running, push the engine stop switch to make sure
that the engine stops immediately.
(4) Restart the engine, and then pull the en- gine shut-off cord (lanyard) to remove the
clip from the engine shut-off switch to
make sure that the engine stops immedi-
ately.
EJU40101Storage compartment checks
Make sure that the storage compartments are
not damaged and that water has not collected
in the compartments. (See page 40 for infor-
mation on the storage compartments.)
EJU41081Fire extinguisher holder, cover, and band
checks

EJU32543Fire extinguisher check
Check that there is a full fire extinguisher on
board.
To check the fire extinguisher, see the instruc-
tions supplied by the fire extinguisher manu-
facturer. Always keep the fire extinguisher
secured in the holder with its cover in place.
Always carry a fire extinguisher on board. A
fire extinguisher is not standard equipment
with this watercraft. If you do not have one,
contact a Yamaha dealer or a fire extinguisher
dealer to obtain one meeting the proper spec-
ifications.
EJU40121Safety equipment check
Check that safety equipment meeting the ap-
plicable regulations is on board.
EJU32352Hull and deck check
Check the hull and deck for damage or other
problem.
EJU32656Jet intake checks
Make sure that the jet intake is not damaged
or clogged with weeds or debris. If the jet in-
take is clogged, clean it. (See page 84 for in-
formation on the jet intake.)
EJU32475Stern drain plug checks
Loosen the stern drain plugs and remove
them, and then make sure that the plugs are
not damaged and that there is no foreign ma-
terial on the threads. NOTICE: Before in- stalling the stern drain plugs, clean the
drain plug threads to remove any foreign
materials, such as dirt or sand. Otherwise,
the stern drain plugs could be damaged,
allowing water to enter the engine com-
partment. Make sure that the stern drain
plugs are tightened securely before
launching the watercraft. Otherwise, water
may flood the engine compartment and
cause the watercraft to submerge.
[ECJ00361]
Securely install the stern drain plugs by tight-
ening them until they stop.

EJU40210Riding position
Operator riding position
The operator should grip the handlebars firm-
ly with both hands and sit astride the seat with
both feet on the floor of the footwell.
Passenger riding position
The passenger(s) should hold on firmly, either
to the person in front of them or to the hand-
grip provided, and sit astride the seat with
their feet on the floor of the footwell. Never al-
low a passenger to ride in front of the opera-

EJU36345Starting the engine on water
WARNING
EWJ01530
Do not apply throttle when anyone is at the
rear of the watercraft. Turn the engine off
or keep it at idle. Water and debris exiting
the jet thrust nozzle can cause severe inju-
ry.
To start the engine:
(1) VX Deluxe / VX Cruiser: If the lock modeis selected for the Yamaha Security Sys-
tem setting, select the unlock mode. (See
page 26 for Yamaha Security System
setting procedures.)
(2) Move the watercraft to an area that is free from weeds and debris, and has a water
depth of at least 60 cm (2 ft) from the bot-
tom of the watercraft. NOTICE: Never
run the engine in water that is less
than 60 cm (2 ft) deep from the bottom
of the watercraft, otherwise pebbles or
sand could be sucked into the jet in-
take, causing impeller damage and en-
gine overheating.
[ECJ00472]
(3) Attach the engine shut-off cord (lanyard) to your left wrist, and then attach the clip
to the engine shut-off switch. (See page
27 for information on operating the en-
gine shut-off switch.) WARNING! Check
that the engine shut-off cord (lanyard)

nozzle.
(7) 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 perform
the procedure again from step 6.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00122]
(8) Turn the water supply off.
(9) Discharge the remaining water out of the cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(10) Stop the engine.
(11) Remove the garden hose adapter, and then securely install the flushing hose
connector cap by tightening it until it
stops.
(12) Securely install the seat in its original po- sition.
EJU41700Cleaning the watercraft
(1) Remove the seat. (See page 38 for seatremoval and installation procedures.)
(2) If the watercraft will be stored for a week or more, rustproof the internal engine
components to help prevent corrosion. (See page 76 for information on rust-
proofing the internal engine compo-
nents.)
(3) Rinse the engine and engine compart- ment with a small amount of water.
NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.
[ECJ00571]
(4) Drain the water from the engine compart- ment. (See page 47 for information on
draining the bilge water.)
(5) Wipe the engine and engine compart- ment with a dry cloth.
(6) Wash down the hull, deck, and jet pump with fresh water.
(7) Wipe the hull, deck, and jet pump with a dry cloth.
(8) Wipe all vinyl and rubber components, such as the seat and engine compart-
ment seals, with a vinyl protectant.
(9) To minimize corrosion, spray metallic parts of the hull, deck, and engine with a
rust inhibitor.
(10) Allow the engine compartment to air dry completely before installing the seat.
(11) Securely install the seat in its original po- sition.
EJU33686Battery care

a month, remove the battery from the water-
craft, check it, and then store it in a cool, dry
place.

Maintenance
Periodic checks and lubrication will keep your
watercraft in the safest and most efficient con-
dition possible. Therefore, make sure to carry
out the periodic maintenance. Safety is an ob-
ligation of the watercraft owner. Proper main-
tenance must be carried out to keep the
exhaust emission and sound levels within the
regulated limits. The most important points of
watercraft inspection and lubrication are ex-
plained on the following pages.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories de-
signed for your watercraft.
Remember, failures that are the result of the
installation of parts or accessories which are
not qualitatively equivalent to genuine
Yamaha parts are not covered by the limited warranty.
Maintenance, replacement, or repair of the
emission control devices and system may
be performed by any marine SI engine re-
pair establishment or individual. Warranty
repair, however, must be performed at an
authorized Yamaha marine dealership.
WARNING
EWJ00311
Be sure to turn off the engine when you
perform maintenance unless otherwise
specified. If you are not familiar with ma-
chine servicing, this work should be done
by a Yamaha dealer or other qualified me-
chanic.
