I am researching the power consumption of a recreational 12 volt marine electric starter for outboard motors Horse power range from 10hp to 250hp and 12 volt marine inboard starters for motors in the 140 HP to big block V8's ( 454 cu in displacement)
I was under the assumption that most 12 volt DC starter motors outboard motors draw up to 200 amps. and the inboard marine starter motors draw anywhere from 350 to 450 amps. Looking at the specifications of the M100 series starters it shows kw anywhere from 3.0 - 4.0 to 5.0 and M 74 series used in small motors 1.7 kw. There is no mention of amperage draw in the specification sheet. Can you tell me why this is.
