Thank you all, those are all good ideas, my boat is on the hard in a different marina at Lake superior, right now, maybe I can check a few things before putting it back in the water. It sure felt like a 110 jolt, I have done a little wiring in my time and have been bit. It also felt like I grabbed a spark plug on my car. But I doubt if there is anything on the boat that could provide that many volts. Not clear what a pushpit is Doug, I do know one thing, I don't want to feel the shock again, am going to relie on my volt tester. Thanks guys, 3 months till summer launch. Bob
