Mercury Marine, originally known as Kiekhaefer Corporation, was founded in 1939 when engineer Carl Kiekhaefer purchased a small, bankrupt outboard motor company in Cedarburg, Wisconsin. Initially, his intent was to use the machinery to manufacture magnetic separators for the dairy industry. However, Kiekhaefer soon discovered the dire need for reliable outboard motors and shifted focus towards redesigning and producing superior, robust outboards. The company's first product, the Mercury Thunderbolt, was launched in 1940 and quickly gained a reputation for its durability and performance.During World War II, Mercury played a crucial role by manufacturing engines and other components for various military applications, thus establishing itself as a significant player in the industrial landscape. With the post-war boom, the company experienced rapid growth and innovation, leading it to become a dominant force in the marine industry. In 1961, the Kiekhaefer Corporation became a division of the Brunswick Corporation, further solidifying its market presence and enabling broader distribution and technological advancements.Currently, Mercury Marine is headquartered in Fond du Lac, Wisconsin. The company is a global leader in producing marine engines, offering a range of products from outboard and sterndrive engines to boat controls and electrification systems. Known for its commitment to quality and innovation, Mercury continues to be a preferred choice among boating enthusiasts and professionals worldwide.
