Cosmetic Care & Maintenance
Tighten all battery connectors securely. Check their
tightness by pulling on the connectors. ey should
not
move from their tightened position. Be sure to
reinstall the positive boot over the battery terminal a er
tightening the battery post connection. While using the
boat, keep an eye on the volt meters to monitor the charge
level of each battery bank. Monitor the charge with the
engines turned o (static condition).
e engine alternators recharge the batteries. A fully
charged battery will indicate between 12 and 14 volts
on the voltmeter. Readings below this could indicate a
dead battery cell or a charging system malfunction which
should be checked by a marine professional.
BATTERIES
Periodically check your battery terminals for corrosion
build-up. If you nd a greenish, powdery substance,
remove the cable connections and clean both the
terminals and the connectors with a wire brush. When
the cleaning is nished reconnect the battery cables
and coat the terminals with an approved grease or
petroleum jelly to help prevent further corrosion.
Check the electrolyte level at least every 30 days on non-
maintenance free batteries, more o en in hot weather.
Also, on non-maintenance free batteries the level should
be maintained between the top of the battery plates and
the bottom of the ll cap opening. Add distilled water
as needed a er charging the batteries. Do not over ll
because sulfuric acid could run over and cause burns
or an explosion. Check speci c gravity levels with a
hydrometer which can be purchased at auto retail stores.
TO PREVENT BODILY 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.
Batteries should be charged outside the boat. Do not
smoke or bring ames near a battery that is being or has
recently been charged. e hydrogen gas generated by
battery charging is highly explosive.
Set the batteries on a block of wood not concrete since the
batteries will lose their charge if le on a cement surface.
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 possible
electrical burns, re, explosion or personal injury.
