Battery
Precautions
When charging batteries, an explosive gas mixture
forms in each cell. A portion of this gas escapes thru
holes in vent plugs and may form an explosive atmo-
sphere around battery if ventilation is poor. This ex-
plosive gas may remain in or around battery for sever-
al hours after it has been charged. Sparks or flames
can ignite this gas and cause an internal explosion
which may shatter the battery.
The following precautions should be observed to pre-
vent an explosion.
1. DO NOT smoke near batteries being charged or
which have been charged very recently.
2. DO NOT break live circuits at terminals of batter-
ies because a spark usually occurs at the point
where a live circuit is broken. Always be careful
when connecting or disconnecting cable clamps
on chargers. Poor connections are a common
cause of electrical arcs which cause explosions.
3. DO NOT reverse polarity of battery cables on bat-
tery terminals.
Recommended Battery
The 2-cycle Outboard type engine requires a 12 volt
battery with a “Cold Cranking Amperage” rating for
cranking and a “Reserve Capacity” rating. The mini-
mum should be a “Cold Cranking Amperage” of 350
amperes and a “Reserve Capacity” of 100 minutes for
engines outlined in this manual.
Operating Engine Without Battery
If desired (or in an emergency), engines equipped
with an alternator can be started and operated with-
out a battery (either disconnected or removed) if
“Warning”, below, is followed.
