RedactedNarrative: On the listed date and time, FWC received notification of a boat fire in Buttonwood Sound, Bayside of the 96 mm.    Caller stated the boat was adrift and on fire and the owner occupant had jumped overboard after fire started.     On my arrival the listed boat was fully engulfed in flames. 
  
  The owner/occupant was picked up by Good Samaritan and brought to Stone Ledge Motel.  Upon speaking with operator, he explained he had just launched the boat and had the battery switch on #1.   He went out approximately 300 feet from shore, stopped boat with engine running and switched the battery switch to All.    Upon doing so he immediately saw black smoke and jumped overboard fearing an explosion.  Within seconds the boat was consumed in flames. 
  
  operator was not injured in the incident and did not require medical attention. 
  
  The boat subsequently sank to the bottom and fire was extinguished.  
   
  Operator did not run bilge fans very long and did not leave them on, it is believed that wiring from the engine charging system shorted when operator switched battery settings and fuel vapor was then ignited.
