2007 YAMAHA GP1300R charging

Features and functions
29
The meter shows the hours of engine opera-
tion that have elapsed since the watercraft
was new.
Voltmeter
The voltmeter is provided to display the volt-
age of the battery.
The voltmeter displays 12 volts or more when
the battery voltage is within specification.
If the voltage displayed is low, return to shore
and, if necessary, have a Yamaha dealer
check the charging system and the battery.
EJU31560Fuel level warning indicator
If the fuel remaining in the fuel tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the low-
est two fuel level segments, the fuel level
warning indicator, and the “WARNING” light
begin to blink. The buzzer also starts sound-
ing intermittently.
If this occurs, refill the fuel tank as soon as
possible.
The warning signals will be cleared when the
engine is restarted after the fuel tank is re-
filled.
EJU31570Oil level warning indicator
If the oil remaining in the oil tank drops to
about 1.7 L (0.45 US gal, 0.37 Imp gal) or the
oil filter is clogged, the oil level warning indica-
tor and the “WARNING” light begin to blink.The buzzer also starts sounding intermittent-
ly.
If this occurs, refill the oil tank as soon as pos-
sible.
The warning signals will be cleared when the
engine is restarted after the oil tank is refilled.
NOTE:
If the oil level warning indicator and the
“WARNING” light blink when there is ade-
quate oil in the oil tank, have a Yamaha dealer
check the oil filter for dirt and clogs.
EJU31580Engine overheat warning indicator
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the “WARN-
ING” light and the engine overheat warning in-
dicator begin to blink, and the buzzer sounds
intermittently.
If this occurs, reduce the engine speed, return
to shore, and then check for water discharge

QSTS cable (jet thrust nozzle end)

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:

Maintenance and care
70
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.

Trouble recovery
77
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.
