The most successful early outboard motor,[1] was created by Norwegian-American inventor Ole Evinrude in 1909.[19] Between 1909 and 1912, Evinrude made thousands of his outboards and the three-horsepower units were sold around the world. His Evinrude Outboard Co. was spun off to other owners, and he went on to success after starting the ELTO company to produce a two-cylinder motor - ELTO stood for Evinrude Light Twin Outboard. The 1920s were the first high-water mark for the outboard with Evinrude, Johnson, ELTO, Atwater Lockwood and dozens of other makers in the field.
