I believe the original OMC was formed in 1929 and early OMC (Outboard Motor Corporation or Outboard Motor Co, depending on who you talk to) was expanding and producing more products than just outboard motors and changed its name in 1936 to the Outboard Marine & Manufacturing Company. (OMMC) They changed the name again in 1956 to Outboard Marine Corporation. or the OMC we are more familiar with today.
