BASED ON INFORMATION TO DATE:  

Based on statements made by the passenger and operator of Vessel #1, They were idling out of the slough where they had spent the night on their cabin boat.  The boat started running a little rough so P1 gave it a little throttle.  He did indicated he was running the installed ventalation system.  P1 stated that his passenger was in the cabin when a flash fire ignited in the engine compartment and came out into the floor area/vent area and then immediately receded.  As soon as it receded, it ignited again and quickly engulfed the boat. P1 and his passenger were forced to jump overboard and swil ashore.  They were picked up by a fisherman and taken to his house where they notified Rhea County SO and TWRA.  P1 indicated that he had some carburator work within the last three weeks.  He did have visible blisters on his legs, ankles, and feet but refused treatment.
