RedactedNarrative: GWS went to the west and observed a blue and white Bayliner sinking.  The occupants were jumping off each wearing a life jacket.  I grabbed deputy who was on scene and retrieved a patrol boat.  We launched and drove to the accident site.  Occupants had made it to shore by another boat.  I found the boat owner who stated the following.
  
   Operator was driving the boat when it sank.  Subject was on the tube they were towing.  Subject stated that they heard a loud noise then a crack and his son looked in the engine compartment which was filling with water.
  
  Dickinson Fire and Rescue towed Subject boat back and East End Auto winched the vessel back onto the boat trailer.  It was photographed the boat and examined the motor area.  There were some internal motor parts and metal off the motor and water running out of the seal for the transom.  Subject pulled out the oil plug and water was running out of the oil hole. 
  
  The motor which had a flywheel that had come apart contributing to the motor issue and its sinking as the Mercruz motor pumped the boat full of water.
