To avoid collisions:
Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vi-
sion of others.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.
Do not follow directly behind watercraft
or other boats. Do not go near others to
spray or splash them with water, go too
close to other boats, or go too fast for
the traffic conditions. Avoid sharp turns
or other maneuvers that make it hard for
others to avoid you or understand where
you are going. Avoid areas with sub-
merged objects or shallow water.
Take early action to avoid collisions. Re-
member, watercraft and other boats do not have brakes. Do not release the
throttle lever when trying to steer away
from objects—as with other power-
boats, you need throttle to steer.
ECJ01341
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, caus-
ing impeller damage and engine overheat-
ing.

EJU44390Beaching and docking the watercraft
To beach the watercraft (VX-C):
(1) Make sure that there are no boats, swim-mers, or obstacles near the beach.
(2) Release the throttle lever to reduce speed about 70 m (230 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.
[EWJ00602] 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.

(4) Get off the watercraft and pull it up on the beach.
To beach the watercraft (VX / VX DELUXE /
VX CRUISER / VX LIMITED):
(1) Make sure that there are no boats, swim- mers, or obstacles near the beach.
(2) Release the throttle lever to reduce speed about 70 m (230 ft) before you
reach the intended beaching area.
(3) Slowly approach the beach using the throttle lever and RiDE lever to control
the watercraft speed. 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 damage and
engine overheating.

(4) After reaching land, stop the engine, and then get off the watercraft and pull it up
on the beach. To dock the watercraft (VX-C):
(1) Make sure that there are no boats, swim-
mers, or obstacles near the dock.
(2) Release the throttle lever to reduce speed about 70 m (230 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.
[EWJ00602]
(4) Come alongside the dock and get off the watercraft.
To dock the watercraft (VX / VX DELUXE /
VX CRUISER / VX LIMITED):
(1) Make sure that there are no boats, swim- mers, or obstacles near the dock.
(2) Release the throttle lever to reduce speed about 70 m (230 ft) away from the
dock.
(3) Slowly approach the dock using the throttle lever and RiDE lever to control
the watercraft speed.
(4) After coming alongside the dock, stop the engine, and then get off the water-
craft.
EJU37194Operating 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 107 for
information on the jet intake.)

the water
ECJ01311
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 pas-
sages.
To discharge water from the cooling water
passages:
(1) Make sure that the area around the wa- tercraft is clear, and then start the en-
gine.
(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.

EJU37146
Post-operation careEWJ00331
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 deteriora-
tion of the jet pump and hull. Marine organ-
isms and corrosion are some of the
conditions that can shorten the life of many
watercraft components.
EJU46370Flushing the cooling water passagesECJ01311
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. (See page 54 for seat removal and installation procedures.) (3) Connect the garden hose adapter to a
garden hose.
(4) Loosen the flushing hose connector cap and remove it. Insert the garden hose
adapter into the flushing hose connector
by pushing and twisting it until it is se-
curely connected.
(5) Connect the garden hose to a water tap.
(6) Make sure that the area around the wa- tercraft is clear, and then start the en-
gine. Immediately after the engine starts,
fully turn the water supply on so that wa-

Emergency proceduresEJU44590Cleaning the jet intake and impellerEWJ00783
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 water-
craft above trolling speed until they have
been removed.
[ECJ00654]
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
watercraft.
(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: When turning the watercraft
on its side, support the bow so that
the handlebars are not bent or dam-
aged.
