On August 3, 14 2013 at approximately 2303hrs, I was contacted by dispatch to a call reference a boat on fire, located at Watson Island Boat Ramp, within Miami-Dade County.  Upon arrival, I observed a vessel, later identified as a 1989 Wellcraft white and blue in color, bearing FL 7778 GX, partially submerged due the extensive structural damage caused by the fire. Miami Fire Rescue was at the scene and provided with Fire Marshall case number (55109 Engine 5 arrow 1) see attachment. 

  Afterwards, I made contact with the owner/operator. The owner/operator stated that he launched the vessel at the boat ramp; he turned the vessel engines compartment blowers ON for five minutes and started the engine. After approximately 10 minutes, he observed fire and smoke coming from the engine compartment. Operator stated that he tried to extinguish the fire, but he was not able to do it, so he abandoned the ship and called 911 (refer to witness statement). He believed that the engine exhaust somehow ignited fuel vapors in the engine compartment. 

 There were no injuries sustained or reported. The owner assumed responsibility
