      OMC Sterndrive Parts

      Formed in 1929, the Outboard Marine Corporation went on to design their lines of outboards and sterndrives that recreational boaters today know as OMC. OMC would invest in new technologies, including the newer stern-drive engines that would change recreational boating forever.

      Sterndrive or inboard-outboard motors proved to be just as versatile as outboards (outselling them at a rate of 10:1) and with better fuel efficiency and overall dependability. It was official: the new, technologically superior motors were a hit, but there was a problem. Due to their technological superiority, dealers at the time were unable to properly maintain or repair them. In time, the knowledge was transferred throughout the field. The popularity of the sterndrives continued after converting their engines to fuel injection, enabling literal turnkey starts and enhanced fuel efficiency in the process. But you or your marine technician will never have a problem locating the right OMC parts whenever you need them. The next time you need OMC sterndrive parts for your boat, trust that Wholesale Marine will have what you need in stock and ready to ship.
