ment and connect the battery leads to the
battery terminals.
(2) Connect the breather hose to the battery.
(3) Secure the battery in place.
WARNING
EWJ00400
Be sure to connect the breather hose to

if the breather hose is damaged, obstruct-
ed, or not connected properly.
CAUTION:
ECJ00260
After installation, make sure that the bat-
tery leads are properly connected to the
battery terminals.
EJU34490Fuel injection system
The fuel injection system was set at the
Yamaha factory. If the fuel injection system
needs to be adjusted, have a Yamaha dealer
service the watercraft.
CAUTION:
ECJ00220
Do not attempt to adjust the fuel injection
system. If the settings are disturbed by
someone who does not have the neces-sary technical knowledge, poor engine
performance and damage may result.
EJU34500Checking the trolling speed
(1) Place the watercraft in the water.
(2) Start the engine and warm it up. Use the
tachometer in the multifunction informa-
tion center to check the trolling speed.
If the trolling speed is out of specification,
have a Yamaha dealer service the watercraft.

Emergency procedures EJU34630Cleaning the jet intake and impeller
If weeds or debris get 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. If
there is any sign that the jet intake or impeller
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.
WARNING
EWJ00780
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 incontact with the rotating parts of the jet
pump.
CAUTION:
ECJ00650
If weeds or debris get caught in the jet in-
take, do not operate the watercraft above
trolling speed until they have been re-
moved.
(1) Turn the watercraft on its side as shown.

Trouble recovery
95
CAUTION:
ECJ00660

Place a suitable clean cloth or carpeting
underneath the watercraft to protect it
from abrasions and scratches.

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.
(2) Remove any weeds or debris from
around the drive shaft, impeller, jet pump
housing, and jet thrust nozzle.
If debris is difficult to remove, consult a
Yamaha dealer.
CAUTION:
ECJ00670
Always avoid operating your watercraft in
areas where weed growth is thick. If travel-
ing in weeded areas is unavoidable, oper-
ate the engine alternately at partial throttle
and full throttle. Weeds tend to accumu-
late more at a steady speed and at trolling
speed. If weeds clog the jet intake or im-
peller area and cause cavitation, follow the
cleaning procedure above.
EJU34640Jumping the battery
If the watercraft battery has run down, the en-
gine can be started using a 12-volt booster
battery and jumper cables.
WARNING
EWJ00790
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes, or clothing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water or
milk. Follow with milk of magnesia, beatenegg, or vegetable oil. Call a physician im-
mediately.
Eyes: Flush with water for 15 minutes and
get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flames, cigarettes, etc., well away.
If using or charging the battery in an en-
closed space, make sure that it is well ven-
tilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHILDREN.
EJU34660Connecting the jumper cables
(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.
CAUTION:
ECJ00680
Do not connect the end of the negative (–)
jumper cable to the negative (–) battery
terminal of the watercraft battery! Make
sure that all connections are secure and
correct before attempting to start the en-

gine. Any wrong connection could dam-
age the electrical system.
(4) Start the engine, and then disconnect the
jumper cables by reversing the steps
above.
CAUTION:
ECJ00690

Never push the start switch while the en-
gine is running.

Do not operate the start switch for more
than 5 seconds, otherwise the battery
will be discharged and the engine will
not start. Also, the starter motor could
be damaged. If the engine does not start
in 5 seconds, release the start switch,
wait 15 seconds, and then try again.
EJU34680Replacing the fuses
The fuses are located in the electrical box.
To replace a fuse:
(1) Remove the cap on the electrical box.(2) 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
EWJ00800
Do not use fuses of higher amperage than
recommended. Substitution with a fuse
that has an improper rating can cause ex-

tensive electrical system damage and pos-
sible fire.
EJU34710Towing the watercraft
If the watercraft becomes inoperative in the
water, it can be towed to shore.
If the watercraft must be towed in an emer-
gency using a towline, the operator should
ride the watercraft, holding onto the handle-
bars.
CAUTION:
ECJ00720

Tow the watercraft at 5 mph (8 km/h) or
less, otherwise water could enter the en-
gine through the exhaust passages or
through the air intake and flood the en-
gine compartment if it is towed too fast.

Tow the watercraft using the bow eye
only.

The bow must be kept up out of the wa-
ter during towing to prevent water from
entering the engine compartment.
WARNING
EWJ00810

The watercraft should only be towed in
an emergency.

The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down. A
good rule of thumb is a towline that isthree times the combined length of the
towing boat and the watercraft.

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 rider on the watercraft.
EJU36150Submerged 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!
In an emergency:
(1) Beach the watercraft and remove the
stern drain plugs to drain the water from
the engine compartment. (See page 54
for more information.) Remove the stor-
age compartment drain plugs to drain the
water from the storage compartments.
(2) Install the stern drain plugs and storage
compartment drain plugs.
(3) Disconnect the spark plug caps, and then
remove the spark plugs.
CAUTION:
ECJ00760
Do not connect the spark plugs to the
spark plug caps.
(4) Disconnect the fuel injector couplers.
CAUTION:
ECJ00770
Cover the disconnected fuel injector cou-
plers so that they do not get wet. If the cou-
plers get wet, they could corrode, which
could lead to poor connections.
(5) Crank the engine for 5 seconds at wide
open throttle. Repeat this step until all of
the water in the cylinders has been ex-
pelled.
