Curtiss OX-5

Thousands of OX-5 water-cooled engines were produced in the United States during World War I, primarily for the Curtiss Jenny airplane. The engine, a refinement of a 1914 design, was rated at only 90 hp. Compared to other airplane engines of the period, it was very reliable. Some OX-5 engines are still being used in restored Jenny airplanes throughout the nation.
