RedactedNarrative: On Friday July 27 operator was operating his 1976 Silver Queen 36'' boat (TN 0043 MJ).  Operator and his wife were aboard the vessel.  Operator started the vessel and had run the engines for approx.. 15 minutes to warm them up before leaving the dock at Clarksville Marina.  They left the dock and traveled approx. 200 yards from the marina when the starboard engine quit running.  Operator attempted to restart the engine a few times with no success.  Occupant said at this time they still had the blowers on their engine running.  Occupant called Clarksville Marina and informed they may need a tow back to the dock.  Operator attempted to start the engine one more time.  On this attempt the starboard area of the vessel exploded.  They put on life jackets, jumped in the water and swam to shore.  Personnel from Clarksville Marina hooked to the vessel and towed it to the far shore of the marina to keep the burning boat away from the marina and docks.  Clarksville Fire reported to the scene and dealt with the fire after a large portion of the boat had already burned.
  
  Occupant stated they had recently had some electrical work done on the boat.  The boat had been started but they had not moved the boat from the location where it was docked when the work was done.
