We found a 2011 Benny 2274 GLI with 84 hours on it. It comes with a 115 hp Merc 4 stroke, has 25" pontoons with lifting strakes. The boat has only been used in fresh water and I need it for saltwater. It will be sitting in saltwater all season. I know I have to have it bottom painted and have zincs added. What else needs to be done? Asking 26K. I think it's worth maybe 22?
