Marine Racing Duesenberg W-24 Engine

Horace Dodge, Jr. liked fast boats and Unlimited Class boat racing. He hired the Duesenberg Brothers Racing (Augie and Fred) in 1925 to design, build and deliver two of these W-24 marine engines. The W shape was made up from three double overhead camshaft straight 8 engines all going to a common crankshaft. There are the right, center and left banks of 8 cylinders to this engine.

Mr. Dodge Horace Dodge Jr. (son of one of the Dodge Bros.) wanted this new boat racing engine for his racing activities. Besides racing he also was a production wooden boat builder (starting in 1923). His production boats were called Dodge Watercars. His first factory was in Detroit, MI. But, he is known for his Newport News, VA factory that he had built to his design specs and that opened in 1930. That business closed in 1936. Its building is now the home to the Mariner’s Museum.

Two Duesenberg W-16 engines were delivered in the summer of 1926. However, the success of these engines came much later. That racing engine last win was with Dan Arena who drove one of his boat designs (Notre Dame) to First Place in the 1940 President’s Cup. Along the way, these engines had different owners, were installed in several racing boats by those engine owners, and had several famous racing engine experts work on them, various carburetor set-ups (both in number and throats of each carb), and supercharging. Starting out at around 450-475 Hp in the later 1920s, the final supercharged engine made 850 Hp at 5,000 RPM in 1940.

Engine specs for the W-24 Duesenberg were 623 cu. in. with a bore of 2.875 inches by a 4 inch stroke.
