RedactedNarrative: On April 26th, 2020 I Officer, of the Florida Fish and Wildlife Conservation Commission, responded to a call of a vessel that had caught on fire. Before I could get on scene I was redirected to the hospital where I collected the statements from the occupants. On April 26th subject and his family left from a sandbar just northeast of the railroad bridge where they had spent the day. 
  
  After packing up subject began to idle from the sand bar into deeper water. After approximately 10 minutes they noticed that the vessel was running different, but no one thought it was anything to be concerned about. Moments later there was an explosion in the engine compartment causing one person to be thrown from the vessel. Shortly after the explosion all the other occupants jumped from the vessel and were later picked up from the water by a nearby boat. 
  
  I determined that the engine bay exhaust fan was either not engaged long enough prior to starting the boat, or the fan was not operational. This allowed gas vapers to accumulate in the engine compartment resulting in the fire and explosion that burned the vessel. 
  
  Occupant2 received 1st degree burns to his right forearm and chest.
  
  Occupant3 received 1st degree burns to her right arm and torso.
  
  Occupant4 received 2nd degree burns to her right tricep and back.
  
  Operator refused treatment of his injuries, he did receive minor burns to his left forearm.
