closed space, make sure that it is well ven-
tilated. Always shield your eyes when
working near batteries.

(1) Disconnect the negative (–) battery lead.
(2) Disconnect the positive (+) battery lead.
(3) Disconnect the breather hose.
(4) Unhook the battery bands, and then re-
move the battery from the watercraft.
Checking the battery
●Make sure that the battery case is not dam-
aged.
●Make sure that the battery terminals are not
corroded or damaged.
●Make sure that the breather hose is not
clogged or damaged.Checking the electrolyte level
Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
If the electrolyte level is low, add distilled wa-
ter to raise it to the specified level. NOTICE:
Use only distilled water for replenishing
the battery, otherwise battery life could be
shortened.
[ECJ00241]
If distilled water was added, check the battery
voltage.
It is recommended to have a Yamaha dealer
check the battery voltage and charge the bat-
tery. If you charge the battery yourself, be
sure to read and follow the instructions provid-
ed with the battery tester and charger you
use. NOTICE: Do not attempt to charge a
battery hastily. Battery life could be short-
ened.
