Like the 1/3 scale Clarke 1-cylinder engine, the full-size version of this motor, a Clarke 2-cylinder, was originally manufactured in Michigan in the 1930s. It operates in the same manner, with the entire motor operating underwater to keep it cool while air is ducted down through the cast case. The copper exhaust pipe runs up above water level and then back down to exhaust under water. This keeps water from entering the motor through the exhaust pipe when the motor is not running. The 1/3 scale Clarke 2-cylinder model is 6″-long, 3″-wide, and 10″-high. This model is a copy of the full-size 2-horsepower motor and was made in 2002.
