RedactedNarrative: Operator of vessel was out fishing with son and father.  Near a rock causeway the engine stopped working and began to take water in the engine compartment.  Operator attempted to use trolling motor but wind and waves were too strong.  The boat drifted and collided with the causeway.  
  
  Operator exited the boat on the causeway and attempted to keep boat away from rocks.  Father and Son remained on board and eventually got the engine started.  They attempted to return to launch when engine died again.  While trying to put down the trolling motor Father was knocked overboard by a wave.  He was wearing a PFD and was pulled to safety on the causeway by Operator.  The boat with Son continued to drift into the causeway.  Eventually it was secured to the rocks and Son got off.  Vessel sank next to causeway and is a total loss.
