Maintenance and care
62
(2) Clean the battery casing using fresh wa-
ter.
(3) If the battery terminals are dirty or corrod-
ed, clean them with a wire brush.
(4) Fully charge the battery.
(5) Apply Yamaha Marine Grease or
Yamaha Grease A to the battery termi-
nals, and then store the battery in a cool,
dry place.
(6) Check the battery at least once every 2
months and fully charge it if necessary.
CAUTION:
ECJ00100
Always keep the battery charged. Storing
a discharged battery can cause permanent
battery damage.
To check the condition of the battery, check
the specific gravity of the electrolyte or mea-
sure the voltage at both battery terminals.
Charge the battery if the voltage is less than
12 volts.
It is recommended to have a Yamaha dealer
check the specific gravity and charge the bat-
tery. If you maintain the battery yourself, be
sure to read and follow the instructions provid-
ed with the battery tester and charger you
use.
EJU33720Cleaning the watercraft
Clean the watercraft before storing it for a long
period.
WARNING
EWJ00260
Do not spray flammable rust inhibitor
products on engine surfaces while the en-
gine is hot. The sprayed substance or pro-
pellants could catch fire.
(1) Wash down the hull, handlebars, and jet
unit with fresh water.
(2) Rinse the engine and bilge area with
fresh water. Drain all of the water and
wipe up any remaining moisture with
clean, dry rags.
CAUTION:
ECJ00110
Do not use high-pressure water when rins-
ing the engine and bilge area as severe en-
gine damage could result.
(3) Spray the engine’s exterior with a rust in-
hibitor and lubricant.
(4) Wax the hull with a non-abrasive wax.
(5) Wipe all vinyl and rubber components,
such as the seat and engine compart-
ment seals, with a vinyl protectant.

QSTS cables (pulley end)

QSTS cables (handlebar end)
Remove the QSTS cable housing. Spray a
rust inhibitor into the outer cables. Reinstall
the QSTS cable housing.

Intermediate housing
Fill the intermediate housing with water-re-
sistant grease through the grease nipple
using a grease gun.
EJU34450Checking the battery
Check the level of the battery electrolyte and
make sure that the negative (–) and positive
(+) battery leads are tightened securely.
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, beaten
egg, 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.
Grease quantity:
Initial 10 hours or 1 month:
33.0–35.0 cm³ (1.12–1.18 US oz)
(1.16–1.23 Imp.oz)
Every 100 hours or 12 months:
6.0–8.0 cm³ (0.20–0.27 US oz)
(0.21–0.28 Imp.oz)

KEEP OUT OF THE REACH OF CHILDREN.
CAUTION:
ECJ00230

Be careful not to place the battery on its
side.

Be sure to remove the battery from the
battery compartment when adding elec-
trolyte or charging the battery.
To replenish the battery:
(1) Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
(2) Refill the battery with distilled water if
necessary.
CAUTION:
ECJ00240
Normal tap water contains minerals that
are harmful to a battery. Use only distilled
water for replenishing the battery.
To recharge the battery:
CAUTION:
ECJ00250
Do not attempt to charge a battery hastily.
Battery life could be shortened.
It is recommended to have a Yamaha dealer
charge the battery. If you charge the battery
yourself, carefully read the battery charger in-structions before charging and follow the
points below.
(1) Remove all of the battery caps.
(2) If the electrolyte level is low, add distilled
water to raise it to the specified level.
(3) Set the charging rate to 1.9 ampere and
charge the battery slowly until the explo-
sive gases are discharged vigorously
from the battery cells.
To install the battery:
(1) Place the battery in the battery compart-
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
the battery. Fire or explosion could result
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.

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

tilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHILDREN.
EJU34650Connecting 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 unpainted bolt on the
cylinder head.
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-
