Yeah, I agree about the unique nature of the tanks and I am willing to make the effort, however I just don't want to do anything that will hurt the boat. Other than the ballast, my boat is now in exceptional shape. I can live with the ballast bags, until I get the balls to start cutting in the floor board. My next step is to figure-out how far back the leak is. I plan on parking the boat on an elevated driveway and measuring a gallon of water at a time in to the ballast. When it starts to leak, I will try to get a mirror or camera in the tank to see how far down the leak is. If it's close enough and I can identify it, I will engineer some type of tool to allow me to put some marine-tex (easy no-frills sealer). My biggest worry is I won't be able to identify the leaky area or it is not close enough for me to view. My second biggest worry is I find the leak and need to create a working space by cutting an 8 or 10 inch hole, and subsequetly hit a stringer. I think I could use the sender space to measure around it enough to rule-out a stringer in that area. I could then mount the level indicator in the deck plate. Seems like the easist way, now I just need to do some more research. Any other ideas on how to get access?
Thanks
