RedactedNarrative: The operator pulled up to the dock with the intent to load the boat onto the trailer. He tied the boat to the dock and tried to shut off the engine, but the engine continued to run. The operator then tried to disconnect the battery cables but stated the boat fire began almost immediately and he and his two passengers got off the boat. 
  
  When the deputy talked to the operator, he stated that the boat was operating and driving fine. He said the issue he was having was the key was not turning off the motor. He turned it to the "off" position and the motor continued to run. He did not try to pull the kill switch on the key. The throttle was in neutral. He stated they started to pull wires and observed several wires already melted. He said he looked up and the motor was on fire. The fire was extinguished by the fire department. The heaviest burned area was the rear right side of the boat. There was a hole in the boat caused by the fire. The boat was a total loss. There were no injuries associated with this incident.
