I am doing inventory at a small museum, Tallahassee Antique Car Museum, Tallahassee, FL., which also has a collection of approximately 250 antique outboard motors. Many are Johnson (1930-1950), Evinrude, (1916-1951) and Mercury (1950-1960),roughly 150 of these brands. I am trying to get a ballpark figure on the value of a 1915 Amphion 3 or 4 hp (?), 2 cylinder and a 1915 Sweet, Model GP, 4 hp both in excellent condition. Sorry no photos are attached as I haven’t figured out how to attach them this message.
