EJU43472Raising the reverse gate (EX
DELUXE / EX LIMITED)
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 cablesEWJ01251
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.

EJU34716Towing the watercraftEWJ00812
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.
