RedactedNarrative: operator was operating his 26ft Crownline boat, IL 7799 KT, north on the Illinois river approximately 13:35pm on 09/04/2016 when he struck a large deadhead below the waters surface between the shore and the red bouys.  T
  
  he collison with the fixed object stopped the engine and left the boat dead in the water.  Operator and the other (6) passengers were uninjured and were able to signal to another boat for assistance, and were towed back to the Meredosia boat launch.  Operator was following another vessel who also struck the same obstruction rendering that vessel inoperable. 
  
  Operator advised he had not been on the river long, and had launched the vessel at the Naples boat launch.
  
  The vessel had damage to the lower unit and the hull in excess of $2,000.00, and the vessel was insured by State Farm. I believe the high water obstructed the view of the deadhead, which was a contributing factor to the accident. Operator was given a copy of the IL Conservation Police Operator BAR with instructions to return the completed form to the IDNR.
