Thanks. I have all the info I can use for the battery setup. My luck while cleaning bottom this afternoon a small piece of the hull dropped out? Not too big about the size of a silver dollar. This would explain last years unexplained high water levels in the bilge. I will scour the repairs section for advise on bottom repairs. I have been taking pictures of my modest attempt at bringing my 73 back to life. I will post later. Shicks you didn't worn me about the bottom falling out.
