RedactedNarrative: On July 15th at approximately 1400 hours, I received a call from Game Warden about a boat that had an explosion and caught fire. Warden could not respond and asked if I was available to respond. I got on scene at approximately 1430 hours. The accident happened on Fort peck Reservoir in the bay in front of the Fort Peck Marina. The accident only involved one boat. 
  When I arrived on scene, the owner of the boat and other individuals managed to get the boat loaded on the trailer. The boat still had flames coming off the boat. They pulled the boat up and away from the fuel station. Once the boat was pulled away, the fire department finished putting out the fire. 
  Once the fire was put out, I talked with the operator of the boat during the accident. The operator had explained to me that she had fueled up the boat and was backed down into the water. Once backed into the water, the operator had started the boat and backed off the trailer. Once off the trailer the boat had died. When trying to start the boat back up it was not starting. The operator had continued to attempt start the boat, after a few times the operator heard a backfire type noise and then there was an explosion in the motor compartment and caught fire. 
  There were four occupants on the boat during the accident. Out of the four occupants on the boat, there was only one with injuries. The occupant with injuries got transported to the hospital with burn marks on her leg.
  After I completed my interview with the operator, I took pictures of the boat and wrote down all the boat information. The inside of the boat and part of both sides were completely burnt. Based on the information I gathered during my investigation, the boat had a mechanical malfunction in the motor compartment that caused an explosion and caught fire. I believe that it was no fault to the operator.
  Nothing else follows.
