RedactedNarrative: Dispatched to a vessel fire at Eddy Creek Marina at 0831 hours on 6-10-2017. Upon arrival I saw a vessel that had burned to the water line and was near the shore just left of the boat ramp closest to docks at marina. The fire department had extinguished the vessel prior to my arrival. Upon speaking with the owner/operator, he stated that he had filled the vessel with gasoline this morning prior to launch. He stated that he had not operated the vessel this year and this morning was the first time. He stated he turned on the blowers prior to starting engine and they sounded to be functioning properly. He stated shortly after launch and the engine starting, that he heard an explosion and the rear motor cover left the vessel. He stated he jumped from vessel without PFD into lake and swam 50' back to shore. The vessel became fully engulfed shortly after. Fire Crews were able to tow to shore and extinguish the vessel and it partially submerged near the shore. Owner/Operator stated he had no work done on vessel lately and had not experienced and mechanical issues.
