Charging System Alternator
Battery charging system is contained within the belt driven alternator, including the regu-
lator. At cranking speeds, electrical power for the engine is provided by the boat battery
– minimum recommended size is 750 CCA, 1,000 MCA, cold cranking amperes or 105
(Minimum) Ampere Hours. Above 550 RPM, all electrical power is provided by the alter-
nator. Should engine rpm drop below 550 RPM, the alternator is not capable of providing
sufficient output and the battery becomes the primary source of electrical power.
Alternator output (when hot) to the battery @ 2000 RPM is approximately 35 - 41 am-
peres.
