craft over counterclockwise,
otherwise water can enter the engine,
which can result in severe damage.
[ECJ00541]
(3) Start the engine and operate the water-
craft at planing speed to drain the bilge
water from the engine compartment.
(See page 61 for information on draining
the bilge water. If the engine does not
start, see “Towing the watercraft” on
page 106 or “Submerged watercraft” on
page 107.) NOTICE: Do not run the en-
gine at full throttle for at least 1 minute
after the engine has been restarted.
Bilge water in the engine compart-
ment can splash into the engine,
which can result in severe damage.

Beaching and docking the watercraft
To beach the watercraft:
(1) Make sure that there are no boats, swim-
mers, or obstacles near the beach.
(2) Release the throttle lever to reduce
speed about 110 m (360 ft) before you
reach the intended beaching area.
(3) Slowly approach the beach and stop the
engine just before reaching land.
WARNING! You need throttle to steer.
Shutting the engine off can cause you
to hit an obstacle you are attempting
to avoid. A collision could result in se-
vere injury or death.
[EWJ00601] 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 intake, causing impeller dam-
age and engine overheating.
[ECJ00472]
(4) Get off the watercraft and pull it up on the
beach.
To dock the watercraft:
(1) Make sure that there are no boats, swim-
mers, or obstacles near the dock.
(2) Release the throttle lever to reduce
speed about 110 m (360 ft) away from the
dock.
(3) Slowly approach the dock and stop the
engine just before coming alongside it.
WARNING! You need throttle to steer.
Shutting the engine off can cause you
to hit an obstacle you are attempting
to avoid. A collision could result in se-
vere injury or death.
[EWJ00601]
(4) Come alongside the dock and get off the
watercraft.
EJU37193Operating in weeded areas
Always avoid using your watercraft in areas
where weed growth is thick. If operating in

weeded areas is unavoidable, alternately
squeeze the throttle lever and relax your grip
on the throttle lever to vary the engine speed.
Weeds tend to become clogged more when
operating at a steady speed and at trolling
speed. If weeds may have clogged the intake
area, clean the jet intake. (See page 102 for
information on the jet intake.)
EJU40241After removing the watercraft from the
water
NOTICE
ECJ01310
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
After operating and removing the watercraft
from the water, promptly discharge the re-
maining water from the cooling water passag-
es.
To discharge water from the cooling water
passages:
(1) Make sure that the area around the wa-
tercraft is clear, and then start the engine.
(2) Discharge the remaining water out of the
cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(3) Stop the engine.

EJU37145
Post-operation care
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.
After using the watercraft, always take it out of
the water, clean it, and store it. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deterioration
of the jet pump and hull. Marine organisms
and corrosion are some of the conditions that
can shorten the life of many watercraft com-
ponents.
EJU42220Flushing the cooling water passages
NOTICE
ECJ01310
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
Flush the cooling water passages to prevent
them from clogging with salt, sand, or dirt.
(1) Place the watercraft in a horizontal posi-
tion.
(2) Remove the seats and removable water-
tight storage compartment. (See page 49
for seat removal and installation proce-
dures and page 55 for information on the
removable watertight storage compart-
ment.)
(3) Open the stern storage compartment.
(See page 54 for information on the stern
storage compartment.)(4) Connect the garden hose adapter to a
garden hose.
(5) Loosen the flushing hose connector cap
and remove it. Insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.
(6) Connect the garden hose to a water tap.
(7) Make sure that the area around the wa-
tercraft is clear, and then start the engine.
Immediately after the engine starts, fully
turn the water supply on so that water

Emergency procedures EJU34634Cleaning the jet intake and impeller
WARNING
EWJ00782
Before attempting to remove weeds or de-
bris from the jet intake or impeller area,
shut the engine off and remove the clip
from the engine shut-off switch. Severe in-
jury or death could result from coming in
contact with the rotating parts of the jet
pump.
If weeds or debris gets caught in the jet intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine speed
rises. If this condition is allowed to continue,
the engine will overheat and may seize.
NOTICE: If weeds or debris gets caught in
the jet intake, do not operate the watercraft
above trolling speed until they have been
removed.
[ECJ00653]
If there is any sign that the jet intake or impel-
ler is clogged with weeds or debris, return to
shore and check the intake and impeller. Al-ways stop the engine before beaching the wa-
tercraft.
(1) Place a suitable clean cloth or carpeting
underneath the watercraft to protect it
from abrasions and scratches. Turn the
watercraft on its side as shown. NOTICE:
Always turn the watercraft over onto
its port (left) side. When turning the
watercraft on its side, support the bow
so that the handlebars are not bent or
damaged.
