Check the start switch, the engine stop
switch, and the engine shut-off switch for
proper operation.
Push the start switch to start the engine. As
soon as the engine starts running, push the
engine stop switch to verify that the engine
stops immediately. Restart the engine, and
then pull the engine shut-off cord (lanyard) to
remove the clip from the engine shut-off
switch to verify that the engine stops immedi-
ately. (See pages 25 to 26 for information on
proper operation of the start switch, the en-
gine stop switch, and the engine shut-off
switch.)
EJU32680Cooling water pilot outlet
Check that water comes out from the cooling
water pilot outlet while the engine is runningand the watercraft is in the water. (See page
26 for more information.)
EJU32711Multifunction information center
Check the multifunction information center for
proper operation while the watercraft is in the
water. (See page 31 for information on proper

(5) Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See
page 62 for flushing procedures.)
(6) If the watercraft will be stored for a week
or more, lubricate internal engine compo-
nents to help prevent corrosion. (See
page 63 for lubrication procedures.)
(7) 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]
(8) Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3,
if necessary).
(9) Wipe the hull, handlebars, and jet unit dry
with a clean cloth.
(10) Spray a rust inhibitor on metallic parts to
minimize corrosion.
(11) Allow the engine compartment to air dry
completely before installing the seat.

Transporting
Before putting the watercraft on a trailer or
transporting it, be sure to put the shift lever in
the forward position (for VX
Deluxe/VX Cruiser). When transporting the
watercraft on a trailer, secure the tie downs to
the trailer through the bow eye and stern
eyes. NOTICE: Do not attach ropes or tie
downs to any part of the watercraft other
than the bow eye and stern eyes to secure
the watercraft to the trailer. Otherwise, the
watercraft may be damaged. Wrap the
ropes or tie downs with towels or rags
where they touch the body of the water-
craft to avoid scratches or damage. Do not
transport the watercraft with the shift lever
in the reverse position. Otherwise the re-
verse gate may hit an obstacle, which
could cause damage (for VX Deluxe/VX
Cruiser).

Storage
WARNING
EWJ00330
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create a
fire hazard.
Storage for long periods of time, such as win-
ter storage, requires preventive maintenance
to ensure against deterioration. It is advisable
to have the watercraft serviced by a Yamaha
dealer prior to storage. However, the following
procedures can be performed by the owner.
EJU33544Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
(1) Place the watercraft in a horizontal posi-
tion.
(2) Remove the seat. (See page 23 for seat
removal and installation procedures.)
(3) Remove the flushing hose connector
cap, and then insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.
(4) Connect the garden hose adapter to a
water tap using a garden hose.
TIP:
A garden hose is not included.
(5) Start the engine, and then immediately
turn the water supply on until water flows
out continually from the jet thrust nozzle.
NOTICE: Do not run the engine for
more than 15 seconds without supply-
ing water or over 4000 r/min on land,
otherwise the engine could overheat.
[ECJ01050]
TIP:
If you will be storing the watercraft for a pro-
longed period, such as winter storage, top off
the fuel tank with fresh gasoline and add fuel
stabilizer and conditioner to the fuel tank ac-
cording to the manufacturer’s instruction be-
fore starting the engine.
(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. NOTICE: Do not sup-
ply water to the cooling water passag-
es when the engine is not running. The
water could flow back through the
muffler into the engine, causing se-
vere engine damage.
[ECJ00122]
(7) Turn the water supply off, and then force
the remaining water out of the cooling
water passages by alternately squeezing
