Spare parts for Mercury Outboards

Mercury was founded in 1939 by Carl Kiekhaefer in Cadarburg, Wisconsin. The first line of models was some improved Thor outboards, and by the 1950s, the company was already an icon in boating, due to its successful 6-cylinder engine “Tower of Power”. As of today, Mercury produces a very wide range of outboards, starting from portable 2.5HP engines, up to the groundbreaking V12 600HP Verado.
