You fellows brought back some long-dormant memories. I have had all the trolling motors you mentioned at one time or another. You are correct about the Thruster being loud. The Ram was a good motor, but it had the largest motor on it of any, at least twice as large as the current models. I had it in 1979. The Thruster was in 1976. I had one Eagle that was manual control that had a lot of thrust, but could not be tightened to where it would not rattle. It was on a 1980 Venture. The handle had been broken off by the previous owner who admitted he was "relieving" himself in the middle of the lake and lost his balance, grabbed the handle and broke it off. I think I would have made up some story before admitting that!
