RedactedNarrative: operator was operating his 29ft Baha boat, IL 4462 KS, north on the Illinois river at approximately 13:35pm on 09/04/16 when he struck a large deadhead below the waters surface between the shore and red bouys. The collision with the fixed object stopped the engine and left the boat dead in the water.  Operator and the other (8) passengers were uninjured and were able to signal another boat for assistance, and were towed to the Meredosia boat launch.  Operator was following (2) other boast, who also struck the obstruction and were rendered 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 hull in excess of $2,000.00 and the vessel was insured by Country Finicial policy.  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.
