Battery cranking amp?
I need a new battery for my boat. It's a Mako 171 with a 135 Johnson 2 stroke. My battery now is dead, I'm adding a 2nd batt and am using a "Perko" switch to hook them in. My question is how to determine my CCA requirement? I found some exide batts with 500 CCA, is that enough?

You first need to find the minimum cranking amps required by the engine. For a starting batttery the 500 will be large enough. You will need more reserve amps for the other battery.
