We very recently purchaed this boat because well, I don't really know why. We have been told that the boat is a "DUO" roughly 58 model, fiberglass ski boat. It came with a Johnson Sea Horse 35 engine.... We haven't been able to identify this boat thru old magazines, the web, or photos. Can someone help with identifing this boat. It is 16' and needs work, however, it isn't really in too bad a shape for as old as it is. We were told "Bill Penny Tire and Marine" flooded the area with these boats during the 50s and 60s. We have the original manual with the engine purchase but the boat has absolutely no id but the local court house doen't keep information that is that old!
