Op stated he was driving V1 down river between Mile Marker 15 and 16 by Dink Pearson Park in high winds and rough water when  his vessel ran aground.  Op said V1 hit a tree stump which punctured the hull near the port bow and damaged his propellers and outdrives.  Op of V1 said V1 was being repaired at Lakeway Marina.  This Officer responded to Lakeway Marina and inspected V1.  The damage that is outlined on V1 is consistent with a grounded vessel collision.  Cause of grounding is excessive speed and failure to keep a proper lookout.  OP did not obtain a weather report prior to leave mooring.
