RedactedNarrative: The Owner purchased Vessel 1 the day before the incident and had the port side impeller replaced at that time.  The Owner stopped to fuel Vessel 1 at the gas station on the way to the ramp.  The fuel gauge was reading 1/4 full when fueling began; approximately 10.5 gallons were added to the tank before it started spurting out the vent; the gauge never moved from 1/4 full. 
  
  The Operator then launched Vessel 1 and tied it off to the northmost pier.  The Operator then started the starboard motor only and let it idle.  Shortly thereafter, the Operator smelled gasoline and began looking for the source of the small.  The Operator then pulled up the forward of the two deck hatches to check in the bilge.  The Operator was in the process of replacing the hatch when there was an explosion from the boat that knocked him off his feet.  The fire on board following the explosion was put out by the fire department; the Operator refused transportation to the hospital on scene, but later went to the hospital on his own for burns sustained during the incident.
