RedactedNarrative: According to a statement by the owner and operator of the boat, he and his passengers were traveling North on Ft. Loudoun lake.  When in the area of Keller Bend the boat made contact with a log floating in the lake.  When this occurred, a propeller was pushed into the hull causing a groove to be cut into it.  Also, bolts connecting a strut to the hull where pulled loose.  The boat was then used for approximately another two hours.  Once it was discovered that water was entering the boat, the operator "beached" the boat on a rail track system at Concord Yacht Club.  Water came up to the exhaust manifolds of the engines and approximately 12 inches of water came into the cabin section of the boat.  This occurred in an area of the lake where there are residences along the shore.  There are also a two parks in the area, Keller Bend Park on the Knox County side of the lake and Louisville Landing on the Blount County side.  The lake is approximately half of a mile wide in this area.
