Battery
both the both the terminals and the connectors
with a wire brush. When the cleaning is finished
reconnect the battery cables and coat the terminal
with an approved grease or petroleum jelly to help
prevent further corrosion.
Check the electrolyte level at least every 30 days,
more often in hot weather. The level should be
maintained between the top of the battery plates
and the bottom of the fill cap opening.
Add distilled water as needed after charging the
batteries or periodically as needed. Do not over-
fill because sulfuric acid could run over and cause
burns or an explosion.
Batteries should be charged outside the boat. Do
not smoke or bring flames near a battery that is
being or has recently been charged. The hydrogen
gas generated by battery charging is highly explo-
sive. Set batteries on a block of wood rather than
concrete since this procedure will help the batter-
ies from losing their charge.
Do not allow a metal object or loose wires to
spark across battery posts while working close to
the battery. Contact across terminals will cause a
short circuit and personal injury may result.
Frequently check your
battery terminals for
corrosion build-up. If
you find a greenish,
powdery substance,
remove the cable con-
nections and clean
Tighten all battery connectors securely. Check
their tightness by pulling on the connectors. They
should not move from their tightened position. Be
sure to reinstall the positive boot over the battery
terminal after tightening the battery post connec-
tion. While using the boat, use the volt meter to
monitor the charge level of the battery. Monitor the
charge with the engines turned off (static condi-
tion).
The engine alternators recharge the batteries. A
fully charged battery will indicate between 12.3
and 12.6 volts on the voltmeter. Readings below
this could indicate a dead battery cell or a charg-
ing system malfunction which should be checked
by a marine professional.
WARNING
AVOID SERIOUS INJURY!
BATTERIES CONTAIN SULFURIC ACID
(POISON) WHICH ALSO CAN CAUSE BURNS.
AVOID CONTACT WITH THE SKIN, EYES, AND
CLOTHING. IF CONTACTED, FLUSH WITH
WATER FOR AT LEAST 15 MINUTES.
IF SWALLOWED, DRINK LARGE AMOUNTS OF
WATER, OR MILK. FOLLOW UP WITH MILK OF
MAGNESIA, BEATEN EGG, OR VEGETABLE
OIL. GET MEDICAL ATTENTION IMMEDIATELY!
WARNING
AVOID SERIOUS INJURY!
WEAR GOGGLES, RUBBER GLOVES, AND A
PROTECTIVE APRON WHEN WORKING
WITH A BATTERY. BATTERY ELECTROLYTE
CAUSES SEVERE EYE DAMAGE AND SKIN
BURNS. IN CASE OF SPILLAGE, WASH AREA
WITH A SOLUTION OF BAKING SODA AND
WATER.
