of charge. Installing a voltmeter will help
you monitor your battery. If you will not
use the boat for a month or more, re-
move the battery from the boat and store
it in a cool, dark place. Completely re-
charge the battery before using it.
3. If the battery will be stored for longer
than a month, check the specific gravity
of the fluid at least once a month and re-
charge the battery when it is low.
NOTE:
Consult a Yamaha dealer when charging or
re-charging batteries.
