RedactedNarrative: V01 was in the area of Rocky Creek at the Sinclair Dam. Operator stated he was idling along and explained the throttle was sticking several times when he attempted to accelerate. 
  
  Operator stated the throttle eventually loosened and he simultaneously heard a popping sound at the rear of the vessel as the stern area of the boat caught fire. 
  
  Operator explained he and the three passengers bailed out of the vessel and watched as it burned. Upon my arrival, Baldwin County Fire Dept. was on scene and explained to me there was attempt to tow the vessel to the shore line but the vessel sank to the bottom before they could make it. Baldwin Fire explained the vessel sank in 35-40 feet of water adjacent to the Sinclair Dam. No one was injured.  The boat was a total loss.
