RedactedNarrative: Subject stated his Boat went missing on the night of july 13th 2014 after 2100. On july, 14th 2014 at approximately 1000 Offficer and I found the vessel directly across the lake from the marina. Once the boat was recovered damaged was observed on the hull. The skeg in front of the propeller was damaged The skeg was made of fiberglass and broke. The propeller spun and struck an unknown object which eventually broke the retaining brace that held the propeller. This pulled the 8 bolts of the retaining plate out and allowed the propeller to strike the hull of the boat.
