Equipment operation

To install the hood:
(1) Position the hood on the deck so that the
two projections at the front of the hood fit
under the two stays on the deck.
(2) Push down on the hood latch, and then
turn the knob to the “LOCK” position to
securely lock the hood in place.
(3) While holding the steering pole, move the
lock pin to the stowed position, and then
lower the steering pole.
EJU36002Bow rope hole
The bow rope hole is used to attach a rope to
the watercraft when transporting, mooring, ortowing it in an emergency. (See page 67 for
information on towing the watercraft.)
EJU36011Stern rope hole
The stern rope hole is used to attach a rope to
the watercraft when mooring it.
EJU31675Storage pouch
The storage pouch is located on the bottom of
the hood.
Use the storage pouch to store the own-
er’s/operator’s manual, tool kit, and other
small items. The storage pouch is not de-
signed to be waterproof. If you carry objects
that must be kept dry, put them in a water-
proof bag.
To remove the storage pouch:
(1) Remove the hood. (See page 23 for hood
removal and installation procedures.)

Operation
48
see “Towing the watercraft” on page 67
or “Submerged watercraft” on page 67.)
NOTICE: Do not run the engine at full
throttle for at least 1 minute after the
engine has been restarted. Bilge water
in the engine compartment can splash
into the engine, which can result in se-
vere damage.
[ECJ00553]
EJU33302
Beaching 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 90 m (300 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.
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 intakearea, clean the jet intake. (See page 65 for in-
formation on the jet intake.)
EJU41060After removing the watercraft from the
water
NOTICE
ECJ01360
Do not run the engine for more than 15
seconds on land 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.

(4) Open the fuse holder and replace the
fuse with one of the correct amperage.
WARNING! Do not use fuses of a dif-
ferent amperage than recommended.
Substitution with a fuse that has an
improper rating can cause extensive
electrical system damage and possi-
ble fire.
[EWJ00802]
(5) Insert the fuse holder into the electrical
box.
(6) Securely install the cap by tightening it
until it stops.
(7) Securely install the hood in its original po-
sition.
EJU34704Towing the watercraft
WARNING
EWJ00811

The operator of the towing boat must
keep speed to a minimum and avoid traf-
fic or obstacles which could be a hazard
to the operator on the watercraft.

The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
If the watercraft becomes inoperative in the
water, it can be towed to shore.
To tow the watercraft:
Use a towline that is three times the combined
length of the towing boat and the watercraft.
(1) Securely attach the towline to the bow
rope hole of the watercraft being towed.
(2) Ride the watercraft with your body weight
supported on the riding tray. Hold on to
the handlebars in order to balance the
watercraft and keep the bow up out of the
water. NOTICE: The bow must be kept
up out of the water during towing, oth-
erwise water could flood the engine
compartment or water could flow back
into the engine, causing severe en-
gine damage.
[ECJ01330]
Tow the watercraft at 8 km/h (5 mph) or less.
NOTICE: Tow the watercraft at 8 km/h (5
mph) or less, otherwise water could flood
the engine compartment or water could
flow back into the engine, causing severe
engine damage.

If the watercraft is submerged or flooded with
water, drain the bilge water from the engine
