Precision Power Offshore Was founded in 2004 by Ben Wiersum. The company was initially located in a 8,000 sq. ft. leased space in Grand Haven, Michigan. The company began with Ben as the only employee, a basic set of tools, and a borrowed hi-lo. Over the next two years the company grew to include two additional employees as the customer base was increasing rapidly.

In 2008, the company relocated to a 16,000 sq. ft. leased space in Spring Lake, Michigan to accommodate the need for additional space. Heated storage was added to the to the list of offerings as the company continued to grow.

In 2012, the company purchased the property across the street from it's previous location and also acquired additional leased space to give Precision Power a combined footprint of over 36,000 sq. ft.
