Equipment operation
23
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.
EJU36001Bow 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
towing procedures.)
EJU36011Stern rope hole
The stern rope hole is used to attach a rope to
the watercraft when mooring it.
EJU31674Storage 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 22 for hood
removal and installation procedures.)

Operation

(5) Bring your knees up onto the riding tray
and change to a kneeling position as
soon as you can do so.
(6) Move as far forward as possible without
interfering with the movement of the han-
dlebars. Keep your body perpendicular to
the water, with your weight forward and
low.
(7) Once the bow drops, and the watercraft
has leveled out in the water and reached
planing speed, back off the throttle and
select your desired speed.
TIP:

The watercraft will become easier to bal-
ance as the speed increases, because jet
thrust provides stability as well as direction-
al control.

It will take longer for a heavy operator to
reach planing speed than it will for a light
operator.
EJU33203Capsized watercraft
WARNING
EWJ00671
Improper uprighting can cause injury.

Be sure to shut the engine off by pulling
on the engine shut-off cord (lanyard) to
remove the clip from the engine shut-off
switch.

Do not put your hands in the intake
grate.
If the watercraft capsizes, turn it over immedi-
ately.
To upright the watercraft:
(1) Remove the clip from the engine shut-off
switch.
(2) Swim to the rear of the watercraft. Turn
the watercraft over clockwise.
If the port (left) side of the capsized wa-
tercraft is tilting up, push down on the
gunwale so that the port (left) side is
down before turning the watercraft clock-
wise. NOTICE: Do not turn the water-
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 water in the
engine compartment. (See page 28 for
water draining procedures. If the engine
does not start, see “Towing the water-

(4) Open the fuse holder and replace the
fuse with one of the correct amperage.
WARNING! Do not use fuses of higher
amperage than recommended. Substi-
tution with a fuse that has an improper
rating can cause extensive electrical
system damage and possible fire.
[EWJ00801]
(5) Insert the fuse holder into the electrical
box.
(6) Install the cap and tighten it securely.
(7) Install the hood in its original position.
EJU34703Towing 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 5 mph (8 km/h) or less.
NOTICE: Tow the watercraft at 5 mph (8
km/h) or less, otherwise water could flood
the engine compartment or water could
flow back into the engine, causing severe
engine damage.
[ECJ01320]
EJU34733
Submerged watercraft
If the watercraft is submerged or flooded with
water, drain the water from the engine com-
partment. Then, have a Yamaha dealer ser-
vice the watercraft as soon as possible.
(1) Remove the watercraft from the water,
and then remove the hood.
