It would be a haul from watts bar, but Master Marine in Seymour has my vote. The owner worked several years at the factory, was involved in the dealership for a few years when it was out by the airport, and has had this place for several years. His son does much of the work now. He was at the dealership when I got my '93 205, and he was the only one to ever service it (besides me) until I sold it a couple years back. I have not had to do anything outside of warranty with my '08 that I couldn't handle, but when I do it will go to them.
