About Us

Originally founded in the 1990s by Bob Morgan as Big Thunder Marina in Gravois Mills, Big Thunder Marine is now owned and operated by the Ross family, and includes five locations. With multiple locations and a full complement of boat sales and rentals, expert service, and well-stocked pro shops, Big Thunder Marine has become the go-to choice for boaters who want to conquer the waters of Lake of the Ozarks and beyond.

Shortly after purchasing Big Thunder Marina in 2015, the Ross family began expanding, most recently with the opening of a new 19,000-sf showroom in Lake Ozark. While much has changed in the years since the Rosses purchased Big Thunder Marina, what hasn’t changed is their commitment to operate their business as a family for families who share their love of all things boating.

A vast array of sales and service; a small-town approach to doing business…this is Big Thunder Marine.
