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, steering pole, han-
dlebars, and jet unit with fresh water.
(3) Remove the hood and check the engine
compartment for water. To drain excess
water, turn the watercraft on its port (left)
side. If necessary, turn the watercraft up-
side down to drain the water completely.
ECJ00580
CAUTION:
Place a suitable clean cloth or carpeting
G
underneath the watercraft to protect it
from abrasions and scratches.
Always turn the watercraft over onto its
G
port (left) side.
When turning the watercraft onto its
G
side or inverting it, support the bow and
secure the steering pole, otherwise the
steering pole and handlebars could be
bent or damaged.
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 52 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.
ECJ00561
CAUTION:
Do not run the engine for more than 15
seconds without supplying water, other-
wise the engine could overheat.
(7) If the watercraft will be stored for a week
or more, lubricate internal engine compo-
nents to help prevent corrosion. (See
page 53 for lubrication procedures.)
(8) Rinse the engine and engine compart-
ment with a small amount of water.
ECJ00570
CAUTION:
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, steering pole, 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 hood.
