Emergency procedures EJU34634Cleaning the jet intake and impeller 
WARNING
EWJ00782
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 watercraft
above trolling speed until they have been
removed.
 [ECJ00653]
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 wa-
tercraft.
(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, support the bow
so that the handlebars are not bent or
damaged.
 [ECJ00661]
STOP

(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.
EJU34641Jumping the battery 
If the watercraft battery has run down, the en-
gine can be started using a 12-volt booster
battery and jumper cables.
EJU34663Connecting the jumper cables 
WARNING
EWJ01250
To avoid battery explosion and serious
damage to the electrical system:

Do not reverse the polarity of the jumper
cables when connecting to the batteries.

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 33 for information on
starting the engine.)
EJU41880Replacing the fuses 
If a fuse is blown, replace it with the proper
fuse.
To replace a fuse:
(1) Remove the seat. (See page 45 for seat
removal and installation procedures.)

(2) Remove the electrical box cover.
(3) Loosen the cap on the electrical box and
remove it.
(4) Replace the blown fuse with the spare
fuse of the correct amperage by using the
fuse puller on the reverse side of the cap.
WARNING! Do not use fuses of a dif-
ferent amperage than recommended.
Substitution with a fuse that has an
improper rating can cause extensiveelectrical system damage and possi-
ble fire.
 [EWJ00802]
(5) Securely install the cap by tightening it
until it stops.
(6) Securely install the electrical box cover in
its original position.
