RedactedNarrative: On 07/05/2013 at approximately 1445 I was dispatched to American Fork Marina for an 11 year old male with propeller cuts to his legs.  When I arrived on scene the victim was already in the ambulance to be taken to the hospital.  I stopped the driver of the ambulance and asked what the injuries were. I was told that VICTIM had propeller cuts to both of his legs.  
  
  I went to the dock where the boat involved in the accident was located. The operator of the boat, OPERATOR, was still in the boat speaking with a Utah County Deputy.  I did a safety inspection on the boat and found that the proof of insurance was not on board the boat. I made arrangements with Operator for him to send me that information.  The boat is owner by Victim's father Operator.  
  
  When I asked Operator how the accident happened he told me that they were switching kids on the tube.  Victim was in the water between the boat and the tube.  Operator thought the boat was in neutral but it was actually in reverse.  When the propeller hit Victim legs Operator put the boat into neutral and jumped in the water to grab Victim.  He was brought on board the boat and 911 was called as they drove to American Fork Marina. 
  
  Victim was treated at the marina by American Fork Fire Department and then transported to American Fork Hospital.
  
  There did not appear to be any mechanical or electrical problems with the boat.
