Just purchased a 1971 Slickcraft 235 and want to add a 2nd battery. I have every manual in the world for the boat but I can't see anything that tells me actual placement of the batteries. When I got it there was 1 battery mounted in front of the engine on the starboard stringer. Was going to put another on the port side stringer. It is pretty close to the alternator but gives me a couple inches of room. Just not sure what the best way to mount it there is. The starboard battery was c-clamped two 2 slots in the deck but I am hoping for a better solution.
