In Florida, boats are everywhere. Living on a peninsula, people have direct water access in nearly all directions, which means having a boat is a relatively normal thing. For boat lovers, you’ve probably heard of the company Mercury Marine before. And while famous for their collection of beautiful boats revolutionizing the industry, there is another reason to know this company — the secret boat testing site they opened in Florida that has remained a hidden secret within the community.

Few Floridians or avid boat lovers, know about the secret boat testing site in Florida that was purchased by Mercury Marine in the 1950s.

Carl Kiekhaefer took a small, single-engine plane out in 1957 in order to find a secret location where he could test his marine engines day and night without anyone around.

The end result of this search was Lake X — a secret 1,400-acre lake surrounded by forest and swamplands that let Kiekhaefer and his team test out a variety of engines away from it all.

Lake X, as it was referred to by Kiekhaefer and his team, became the stuff of legends — with writers even adopting the name, too.

Teams of workers traveled to Lake X in the early years in order to build boat launches, work buildings, seawalls, an observation tower, and even a six-room motel.

Over the years, Lake X even became a coveted place for race teams and boat builders in order to improve the performance of their boats in private.
