Post-operation care
To keep your watercraft in top shape, always
take it out of the water after using it and per-
form the following procedures. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deterioration
of the jet unit components and hull finish. Ma-
rine organisms and corrosion are some of the
conditions that can adversely affect the life of
many watercraft components.
(1) Remove the watercraft from the water.
(2) Wash down the hull, handlebars, and jet
unit with fresh water.
(3) Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow the water in the bilge to
drain out.
NOTE:
This watercraft is equipped with an automatic
bilge draining system that removes water
from the engine compartment while you are
underway. However, some residual water will
remain.
(4) Place the watercraft in a horizontal posi-
tion.
(5) Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See
page 66 for flushing procedures.)(6) Drain residual water from the exhaust
system by alternately squeezing and re-
leasing the throttle lever for 10 to 15 sec-
onds while the engine is running.
CAUTION:
ECJ00560
Do not run the engine for more than 15
seconds, otherwise the engine could over-
heat.
(7) If the watercraft will be stored for a week
or more, lubricate internal engine compo-
nents to help prevent corrosion. (See
page 67 for lubrication procedures.)
(8) Rinse the engine and engine compart-
ment with a small amount of water.
CAUTION:
ECJ00570
Do not use high-pressure water when rins-
ing the engine or engine compartment as
severe engine damage could result.
(9) Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3,
if necessary).
(10) Wipe the hull, handlebars, and jet unit dry
with a clean cloth.
(11) Spray a rust inhibitor on metallic parts to
minimize corrosion.
(12) Allow the engine compartment to air dry
completely before installing the seat.

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.
EJU33541Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
CAUTION:
ECJ00121
Do not supply water to the cooling water
passages when the engine is not run-
ning. The water could flow back through
the muffler into the crankcase, causing
severe engine damage.
Do not run the engine for more than 15
seconds without supplying water or
over 4000 r/min on land, otherwise the
engine could overheat.
(1) Remove the watercraft from the water
and place it in a horizontal position.
(2) Remove the seat. (See page 26 for seat
removal and installation procedures.)
(3) Remove the flushing hose connector
cap, and then insert the garden hoseadapter 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.
NOTE:
A 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 thrust 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 of the cooling
