Crosley's at Sea

Speedboat of the same type hull as the Crosley

In 1939 Powel Crosley Jr. felt the time was right for Americans to have the option of a small inexpensive car. His first model was a tiny two seater powered by an air cooled two cylinder engine. Two years later he had also started production, using the same engine, of the Crosley Watersprite, a small family boat built in Miami. In 1942 production was redirected to support the war effort. As the war continued the need arose for a small, light engine to power generators in PT Boats (fast boats armed with torpedoes) and amphibious vehicles.

Crosley learned about an engine made from brazed together stamped metal sheets and bought the patent. Soon after, he began production of what would be known as the Cobra engine. The engine was named not for its ferocity, but for the copper used in the brazing process; Cobra being a shortening of copper brazed. As an engine for a generator it proved successful. One test model ran for 50 days around the clock without any problems. Crosley did well producing the small reliable engine during the war. When the war drew to a close, he saw the Cobra engine as an ideal power source for his return to car manufacturing.

The engines were light and fuel efficient, as well as reliable, when operating at a steady speed in a generator. The problem came with installing them in a car where the engine would have to operate under varying speeds and conditions. Lack of reliability and less than stunning performance plagued the early Crosley cars. Despite a “sports” model, they were not known for their speed. One partial exception to this, a Crosley Hot Shot, did win the first endurance race at Sebring, Florida but only because the number of laps required was based on engine size. After several years of trying, with limited success, to make the Cobra engine work in a car, Crosley’s engineers designed a new version with a heavier more reliable cast iron body. Unfortunately this improved engine came too late as his sales had already been waning. As the big auto companies shifted from producing for the war to producing for home, Crosley Automotive sales fell further and the production of Crosley cars stopped in 1952.

While the end of automotive production was a blow to Crosley, it was a boon elsewhere. Lightly used Crosley cars and trucks began to appear for low prices around the nation. It was from this resource that a new phenomenon developed in the world of powerboat racing. It was called the Y or 48 inch class. They were 9 foot long hydroplanes, boats designed to just skim along the surface of the water, equipped with tiny engines up to 48 cubic inches. The small size and light weight of the Crosley engi
