Koehler Kraft Company (originally Mercury Marine) was founded in 1938 as a builder of a popular line of mahogany sport fishing boats and racing runabouts. Clarence Koehler Sr. moved the yard to its current Shelter Island location in 1952. In 1956, Koehler Kraft built the first San Diego Harbor patrol and rescue boat.
