RedactedNarrative: On 8-4-2017 at 2107 hours the Alaska State Troopers received a report that four boaters were ejected from an out of control boat on the Kenai River near Centennial.  It was reported that none of the boaters were wearing life jackets.  
  
  The Alaska State Troopers along with the Alaska Wildlife Troopers, Alaska State Park Rangers, Soldotna Police Department and Central Emergency Services responded to the area via boat and on foot checking the shoreline.  Three of the occupants were able to swim to shore.  The fourth boater was reportedly unable to make it to shore and was last seen floating down river and had reportedly gone under water.  
  
  All search units were unable to locate him and the search was suspended.  Further searches of the area are underway by the Alaska State Park Service.  The cause of the boat malfunction was a faulty steering cable.
