I bought a 1982  V 20 earlier this month    We took it to the lake first and it ran well   noticed gas leaking from the stern, and then lowered the trailer  tongue and it stopped but I think quite a bit leaked before I noticed     took it to the coast and replaced the fuel line that was rotted   thought we were good then went fishing on the bay and made a few stops  then went to start it and we had an explosion which lifted me and my  buddy off the deck,  smoke came out of the forward hatch and we hit it  with the fire extinquisher.  Got towed back. pretty scary, hull looks  fine but I think this old 1982 either had a bad leak in the fill line or  a bad gas tank
