The original aluminum holding tank on my 1992 Hunter 28 has finally failed. It's leaking from the bottom of the tank. As the tank is bigger than the port or starboard aft lockers, I'm guessing that the tank either has to be cut out, or an access hole cut in the aft bulkhead. With an access hole cut in the bulkhead, I could replace with a similar size tank. Otherwise I guess I'm going to have to install a smaller size holding tank. Any Hunter 28 owners have some experience they'd like to pass aong?
