the lock pin into the detent. Make sure that the
lock pin is returned to the stowed position af-
ter installing the hood.

EJU33201Capsized 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.
Be sure to carefully follow the procedures be-
low to prevent injury, or damage to the water-
craft.
(1) Remove the clip from the engine shut-off
switch.
(2) Swim to the rear of the watercraft and up-
right it by turning it clockwise only.
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 as straight as possible and above
planing speed for at least 2 minutes to
discharge any water remaining in the en-
gine compartment. (If the engine does
not start, see “Towing the watercraft” on
page 65 or “Submerged watercraft” on
page 65.) NOTICE: Do not operate the
engine at full throttle for at least 1
minute after the engine has been re-
started. Excessive water in the engine
compartment can splash into the en-
gine, which can result in severe dam-
age.
[ECJ00551]
To stabilize the watercraft when acceler-
ating to planing speed, maintain a low
center of gravity by operating it in the
kneeling position.

Towing 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.
When the watercraft is towed using a towline,
the operator should ride the watercraft, hold-
ing onto the handlebars and supporting his or
her body weight on the riding tray. This will
help keep the bow of the watercraft out of the
water.
Use a towline that is three times the combined
length of the towing boat and the watercraft.Tow the watercraft using the bow rope hole
only.
Tow the watercraft at 5 mph (8 km/h) or less.
The bow must be kept up out of the water dur-
ing towing to prevent water from entering the
engine compartment.
EJU34731Submerged watercraft
If the watercraft is submerged or flooded with
water, follow the procedure below and consult
a Yamaha dealer as soon as possible. Failure
to do so could result in serious engine dam-
age.
(1) Beach the watercraft and remove the
hood.
(2) Turn the fuel cock knob to “OFF”.
(3) Turn the watercraft over far enough to
drain the water from the engine compart-
ment. NOTICE: Turning the watercraft
on its side with the hood removed
could cause damage to the steering
pole. Use two people to provide
enough support to make sure that the
steering pole is not damaged.
[ECJ00701]
(4) Turn the watercraft upright again.
(5) Have the watercraft inspected by a
Yamaha dealer as soon as possible.
NOTICE: Be sure to have a Yamaha
dealer inspect the watercraft. Other-
wise, serious engine damage could re-
sult.
