RedactedNarrative: Subjects put their boat in at Yellow jacket access on West Point Lake and were fishing just south of the Hwy 109 bridge.  While fishing they noticed that the boat had a great deal of water inside the floor.  Operator turned on the bilge pump at this time which did not work.  Operator also attempted to drive the boat to shore and tried to trim the OB motor which would now not work.  While trying to get the boat to shore the boat sank to the waterline and the motor shut off.  Both subjects then went into the water and attempted to swim to shore.  Both indicated they had on PFD’s when in the water.  Operator was close to shore and looked back for his step-son and noticed that he was still near the boat.  Operator’s took off his PFD and swam back to get his step-son and became exhausted doing this.  Stepson held Operator’s head above water and stepson began yelling for help.  Two people were fishing just south of this location and heard the yelling, went to investigate finding the victims in the water a few yards from the sunken vessel.  The Smiths loaded the two victims onto their boat and transported them to Horris King access calling 911 in the process.  Both victims were treated for hypothermia on the scene by Troup County Fire/EMS personnel and both victims refused to be transported.  
       Troup County Deputy transported the subjects to their vehicle at Yellow Jacket access.  
       Marine tow company was called to remove the boat from the water.  It was discovered that the plug was missing from the boat which caused the boat to fill with water and sink.  operator stated that he had installed the plug before launching the boat.
