Emergency proceduresEJU34635Cleaning the jet intake and impeller
WARNING
EWJ00783
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: Always turn the watercraft
over onto its port (left) side. When
turning the watercraft on its side, sup-
port the bow so that the handlebars
are not bent or damaged.
[ECJ00662]

(2) Remove any weeds or debris from
around the jet intake, drive shaft, impel-
ler, jet pump housing, and jet thrust noz-
zle.
If debris is difficult to remove, consult a
Yamaha dealer.
EJU43471Raising the reverse gate
If the RiDE system malfunctions and the re-
verse gate remains in the lowered position,
the watercraft will not be able to move for-
ward.
After raising the reverse gate so that the wa-
tercraft can move forward, immediately re-
turn to shore and have a Yamaha dealer
service the watercraft.
To raise the reverse gate:
(1) Stop the engine and remove the clip from
the engine shut-off switch.
(2) Enter the water and move to the rear of
the watercraft.
(3) Slide the shift rod joint toward the bow,
and then disconnect the shift rod joint
from the ball joint.(4) Raise the reverse gate to the forward po-
sition.
TIP:
While the shift rod is disconnected, the re-
verse gate will not move to the neutral po-
sition or reverse position even if the RiDE
lever is squeezed.
If the RiDE lever is squeezed while the shift
rod is disconnected, the watercraft will
move forward.
EJU34642Jumping the battery
If the watercraft battery has run down, the en-
gine can be started using a 12-volt booster
battery and jumper cables.
EJU34664Connecting the jumper cables
WARNING
EWJ01251
To avoid battery explosion and serious
damage to the electrical system:
Do not reverse the polarity of the jumper
cables when connecting to the batter-
ies.
Do not connect the negative (–) jumper
cable to the negative (–) terminal of the
watercraft battery.
Do not touch the positive (+) jumper ca-
ble to the negative (–) jumper cable.

(1) Connect the positive (+) jumper cable to
the positive (+) battery terminals of both
batteries.
(2) Connect one end of the negative (–)
jumper cable to the negative (–) battery
terminal of the booster battery.
(3) Connect the other end of the negative (–)
jumper cable to an engine hanger.
(4) Start the engine, and then disconnect the
jumper cables by reversing the steps
above. (See page 28 for information on
starting the engine.)EJU43880Replacing the fuses
If a fuse is blown, replace it with the proper
fuse.
To replace a fuse:
(1) Remove the seats. (See page 44 for seat
removal and installation procedures.)

(2) While pushing both sides of the fuse box
cover inward, pull the cover toward the
port and remove it.
(3) When replacing the SCU fuse, remove
the screws, and then remove the fuse.
Install the spare fuse, and then tighten
the screws.
(4) When replacing a fuse other than the
SCU fuse, remove the fuse using the
fuse puller. Install a spare fuse of theproper amperage. WARNING! Do not
use fuses of a different amperage than
recommended. Substitution with a
fuse that has an improper rating can
cause extensive electrical system
damage and possible fire.
[EWJ00803]
(5) Securely install the fuse box cover in its
original position.
(6) Securely install the seats in their original
positions.
If the fuse immediately blows again, the elec-
trical system may be defective. If this occurs,
have a Yamaha dealer service the watercraft.
EJU34716Towing the watercraft
WARNING
EWJ00812
The operator of the towing boat must
keep speed to a minimum and avoid
traffic or obstacles which could be a
hazard to the operator on the water-
craft.
The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
