The two engines will be installed shortly; time to buy batteries. The boat came without any.
The manual does not state an Amp draw for the starters - but of course there is also a large resistance from the intermediate, top and lower gearboxes.

Any one got a definitive figure for the Cold Cranking Amps from a battery?
Its easy to say 'buy the biggest you can afford', but they suddenly leap up in price and weight after a certain point.
If the deep cycle/ domestic battery is joined to the starter battery just for starting - would this not raise the starting amps sufficiently?

Thanks gents, I have had no information from any battery supplier . . .
 
This a oem starter or a aftermarket. After market new style uses less juice.

A new marine dual purpose, sears brand lasted me 5 years.

Was the cheapest one they had. Back then it was 55 American dollars in pounds and ounces i don't know.

About 1 month ago i bought a sears marine starting battery was with trade in was 55 American dollars. Go figure, i guess batteries are not like gasoline. Price on gas goes up.

One battery per motor is all you need. As long as the connection are nice and shiny clean. Don;t forget the grounds they need to be shiny clean also.

Good luck keep us posted.
