RedactedNarrative: Operator of Vessel #1 along with his passengers left the boat ramp at Hunter Park on Lake Granbury and headed downstream for a day on the lake. 
  Operator of Vessel #1, not being too firmiliar with Lake Granbury and its many submerged hazards, did not follow the channel markers that show the clearest and often deepest part of the lake. 
  Operator of Vessel #1, about 1 O minutes into their trip, was in an area with many stumps that lie just under the surface of the water. The vessel struck one of these submerged stumps with its propeller damaging the propeller and possibly the drive system of the vessel. 
  Vessel #1 also had damage to the hull in two places where it appears a piece of the stump got caught in the propeller and caused gashes in the hull. These were not bad enough for the hull to be breeched.
