RedactedNarrative: On July 4th, 2015 O1 had filled the boat with fuel and then went and put it on Breakers Beach at Angostura Reservoir.   Several hours later, O1 attempted to start the boat.  When the motor fired there was an explosion and the interior of the boat caught fire.  O1 and subjects on the beach threw water on the fire and a Park Ranger arrived with a fire extinguisher and put it out.  There were no injuries observed or reported.
