      I have a 1939 Evinrude Elto Cub.  I plan to use the motor on my canoe.  What is the best product to apply to protect the original patina for frequent fresh water marine use?

        Aluminum naturally oxidizes when exposed to air, it protects the surface in most instances from further oxidation. It did that after it was manufactured..
