Maintenance
61
● Drink large quantities of water or milk
followed by milk of magnesia, beaten
egg, or vegetable oil. Get immediate
medical attention.
Batteries also generate explosive hydro-
gen gas; therefore, you should always fol-
low these preventive measures:
● Charge batteries in a well-ventilated ar-
ea.
● Keep batteries away from fire, sparks, or
open flames (for example: welding
equipment, lighted cigarettes, and so
on.)
● DO NOT SMOKE when charging or han-
dling batteries.
KEEP BATTERIES AND ELECTROLYTIC
FLUID OUT OF REACH OF CHILDREN.
CAUTION:
ECM00360
● A poorly maintained battery will quickly
deteriorate.
● Ordinary tap water contains minerals
harmful to a battery, and should not be
used for topping up.
1. Check the electrolyte level at least once a
month. Fill to the manufacturer’s recom-
mended level when necessary. Top up
only with distilled water (or pure de-ion-
ized water suitable to use in batteries).
2. Always keep the battery in a good state of
charge. Installing a voltmeter will help
you monitor your battery. If you will not
use the boat for a month or more, remove
the battery from the boat and store it in a
cool, dark place. Completely recharge
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 recharge
the battery when it is low.
NOTE:
Consult a Yamaha dealer when charging or
re-charging batteries.

● Make sure the main switch (on applica-
ble models) is “

on the battery.
● Reversal of the battery cables will dam-
age the electrical parts.
● If you connect the battery cables in the
reverse order, consult a Yamaha dealer
immediately.
● Connect the red battery cable first when
installing the battery and disconnect the
black battery cable first when removing
it. Otherwise, the electrical parts can will
be damaged.
