I have a "90" 680T and it's on it's third motor. It's a great fishing boat, very stable for it's size, a dry ride, and roomy for a 17 footer. Used it to pull kids tubing years ago and worked fine for that. Even use it to pull six planer boards at a time, the only problem there is you have to keep steering and your buddys reel in the lines. Have a friend who has the 680C with a 90hp and it's basicly the same boat and floor plan. Each of these boats are still in great shape for ten plus years. Find one in good shape and you won't be sorry.
