RedactedNarrative: Operator says he and his son were fishing on board his Ranger boat. Shortly after he turned the engine over to move to a new location, he heard a loud explosion from the outboard motor and observed that a fire had started on the boat. He attempted to put the fire out with the fire extinguisher but was unable to stop it. He and his son jumped off and swam to shore. DGIF and the Army Corps of Engineers were on scene afterwards to tow the boat and investigate the accident.
