Operator stated that the motor suddenly revved up and simultaneously lost power to the drive train.  Operator immediately shut off motor and vessel drifted into shore with the help of wave action.  Vessel beached on shore bow first.  subject jumped out of boat and went around to stern and attempted to hold up the rear of the boat so that the lower unit would not crash against rocks.  While doing so a wave lifted the stern and than slammed it down causing the propeller to strike victim's foot sustaining an approximate 2" laceration to the top of the big tow on his left foot.  Upon removal and inspecting the boat out of the water it was observed that the skeg had been broken off completely approximately 1" below the torpedo.  As well as significant damage to the leading edges of the propeller.  Other stress damage was noted to the lower transom area and lower unit area.  All this damage is indicative to the lower unit striking a submerged object, probably a boulder which are know to be scattered in the area the operator was in.
