Operator was operating (driving) his mother's boat, LA4844FX, on Lake Claiborne along the thousand foot channel.  Weather was clear and wind was calm at night, with fair visibility.  Note, Lake Claiborne is low from water evaporation from little rain and high temperatures. Operator said, I struck a stump in the channel which knocked a hole in the aluminum boat, along a weld, and broke the prop shaft into.  Officer with Claiborne Sheriff's Office confirmed statement as accurate.  Other than damage caused by the stump, vessel was in good working order.  No drugs or alcohol contributed to incident.
