  On April 4th, 2022, at approximately 1530 hours, a 28’ Formula 280SS (V1) vessel was upon it’s boat lift with 6 occupants onboard. While V1 was being lowered into the water, Subject1 was at the helm. V1’s bilge blower was on and functioning properly. 
  
  While V1 was stationary and settled in the water above its lift. Subject1 started V1’s engines beginning with the starboard side, then the port side. With the engines running, smoke began emitting from the engine compartment. Subject1 immediately shut off both engines at which time the explosion occurred. All 6 occupants were thrown within the vessel. Subject2 who was sitting on the cushioned seat attached to the engine compartment cover was thrown upwards within the vessel, landing with his lower half of his body within the engine compartment exposed to the open flames.
  
  V1 sat stationary in the water with both engines off and on fire. Both Subject3 and Subject1 grabbed fire extinguishers and attempted to extinguish the flames. Two people removed Subject2 from the engine compartment and flames. Subject3 exited V1 and retrieved the garden hose from his residence and continued to extinguish the flames. Subject4 exited V1 and called 911. At approximately 1535 hours Cape Coral Fire Rescue arrived on scene, extinguished the fire, and provided emergency medical services. 
    
  According to BFAEI Agent fire scene investigation and examination of V1’s engine compartment. V1’s fuel filler neck was missing, and a strong odor of fuel was in the engine compartment. It is believed that fuel vapors accumulated in the engine compartment and these vapors met with heat and/or sparks caused a vapor explosion leading to the fire. 
  
  Victim1 sustained second degree burn to right shin, and contusion to lower left arm under elbow.; Operator sustained contusion and scrape to left shin and back of right ankle, smoke inhalation.; Subject2 sustained second degree burns to lower 1/2 of body.
