RedactedNarrative: After departing the area of Split Rock Lighthouse, Operator states he struck a submerged object in the area of the Gooseberry River. He reported to the aerial bridge that he had lost steerage and one motor, so St. Louis Co. Sheriff's Office responded and met the boat at Lakehead Boat Basin in Duluth. None of the occupants sustained injury. Life jackets were not being worn and alcohol was not a factor. Operator believes the water depth was 70 feet. It is unknown if a reef was struck or submerged object.
