I've got an early 1950s Crestliner Aluminum boat which has a lot of sentimental value (first boat I fished out of), however the bung leaks regardless of bung. I've contacted the manufacturer to get the bung thread size but the new bung still leaks, to reduce the leak I've wrapped the bung in a plastic bag before inserting it but there is still some leaking. The bilge can take care of the remaining leak but I'd like to fix this issue. Does anyone know of a Southern Vancouver Island company that can re-drill the bung for a larger bung, or offer some other solution?
