Page 7 A 3-Horsepower air cooled single cylinder engine was used as the power plant portion of the first and original Outboard Motor. This engine originated as a motorcycle engine and was obtained from Glen Curtis of Hammondsport, New York. Although heavier then what Mr. Waterman had wished, it was adapted for his purpose. The motorcycle engine used a chain drive connected to the propeller, and it was occasionally put out of commission during the test as a piece of ice came between the chain and the sprocket. Nevertheless this test in 1905 marked the success of the Waterman Porto Motor that was later considered the first mass-produced outboard and the beginning of an industry. Of note is the fact that one of the spectators in the boat when the test was run was R. McDougal Campau of Detroit. It was he who suggested describing the new mechanical device as an "Outboard Motor" coining a new term, and later helped develop a new marine industry. The original Glen Curtis motorcycle engine, which was used to power the first outboard motor was on display in the booth. In addition to the original power plant that Cameron B. Waterman used in his 1905 Detroit River test, other Detroit and Michigan outboard motors were on display, among which were: - circa 1912 Waterman Porto (as in Portable) Outboard Motor, of Detroit, Michigan and featuring rudder steering. - circa 1918 Motorgo built by the Lockwood-Ash Company of Jackson, Michigan and was probably the first private brand outboard that was marketed by the Sears-Roebuck Company. - circa 1929 Caille Outboard Motor produced by the Caille Perfection Motor Company of Detroit, Michigan - circa 1940 Clarke Troller produced by the Clarke Engineering Company of Detroit, Michigan. This holds the honor of being one of the smallest outboard motors ever built, coming in at ten and one half pounds and twenty one inches high. - circa 1950 Chris Craft outboard built at the Grand Rapids, Michigan plant.
