damaged.
To store the battery:
(1) Clean the battery case using fresh water.
(2) If the battery terminals are dirty or cor-roded, clean them using a wire brush.
(3) Apply Yamaha Marine Grease or Yamaha Grease A to the battery termi-nals.
(4) Store the battery in a cool, dry place. NOTICE: Storing the battery in an un-
charged condition can cause perma-
nent battery damage. Check the
battery periodically.
[ECJ00103]
To install the battery:
(1) Place the battery in the battery compart- ment and hook the battery bands onto
the holders.
(2) Connect the positive (+) battery lead (red) to the positive (+) battery terminal.
NOTICE: Reversal of the battery leads
will damage the electrical parts.
[ECJ00262]
(3) Connect the negative (–) battery lead (black) to the negative (–) battery termi-
nal.
(4) Connect the breather hose to the bat- tery. WARNING! Fire or explosion
could result if the breather hose is
damaged, obstructed, or not connect-
ed properly.

(2) Remove any weeds or debris fromaround 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 tothe 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.)EJU43481Replacing the fuses
If a fuse is blown, replace it with the proper
fuse.
To replace a fuse:
(1) Remove the seats. (See page 49 for seatremoval and installation procedures.)

(2) Remove the electrical box cover.
(3) While pushing both sides of the fuse boxcover inward, pull the cover toward the
bow and remove it.
(4) When replacing the SCU fuse, remove the screws, and then remove the fuse. Install the spare fuse, and then tighten
the screws.
(5) When replacing a fuse other than the SCU fuse, remove the fuse using the
fuse puller. Install a spare fuse of the
proper 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.

(6) Securely install the fuse box cover in itsoriginal position.
(7) Securely install the electrical box cover in its original position.
(8) 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.
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 com-
bined length of the towing boat and the wa-
tercraft.
(1) Securely attach the towline to the bow
eye of the watercraft being towed.
(2) Sit astride the seat and hold on to the handlebars in order to balance the water-
craft. 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
engine damage.
[ECJ01331]
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.
[ECJ01322]
EJU36156
Submerged watercraft
If the watercraft is submerged or flooded with
water, drain the bilge water from the engine
compartment. Then, have a Yamaha dealer
service the watercraft as soon as possible.
If the watercraft was submerged:
(1) Remove the watercraft from the water and drain the water from the storage
compartments. (See page 52 for infor-
