John W. Mulford served as president of Gray Marine in 1961 (January 21, 1961 New York Times). His father O. J. Mulford founded the Gray Marine Motor Company which was bought by Continental Motors Corporation in 1944 (Jan. 8, 1956 New York Times). It operated as a subsidiary until 1964 when it was re-organized as a division of Continental. Manufacturing operations were consolidated across the state in Continental's Muskegon, Michigan location; engineering in Continental's Detroit facility. For most of its history, Gray Marine used Continental engine blocks in their marine engines. Continental chose to stop offering gasoline marine engines, only filling existing orders received by October 1966. Instead, a line of marine diesel engines under the Graymarine and CMC brands were to be marketed from 1967-on.
