The gimbel housing on the Daytona was broken, and there was damage to the prop. He may have clipped the rock bar, tweaked the drive and flipped the boat.
Just one of those things. You either know the river, or you go home with an empty trailer or broke boat.
He knows the river just fine and like I said already he did not a clip rock it was not a drivers error it was a mechanical failure!! And if you would have seen the boat in person it is quite evident it did not flip!!!!!!!
