RedactedNarrative: On 27 JUN 15, I, Officer of the Florida Fish and Wildlife Conservation Commission, was on patrol near the 97 mile marker on the bayside. At around 1230, I was with Field Training Officer (FTO), when we heard a call over the radio in reference to a vessel fire near Card Sound. We went en route to the area and approached the vessel around 1300. Sea Tow vessel had already arrived on scene, and had put out the flames. The vessel had been occupied with two occupants (father & son), we confirmed that both occupants of the vessel were unharmed. 
  
  Operator1 stated that he had been operating his vessel out of Homestead Bayfront en route to their rental home in Tavernier. In the vicinity north of Card Sound bridge, Operator1 started to experience engine problems. At first, the vessel stalled out; however, he was able to restart the engine and get back on plane. It was then that he noticed the engine was on fire. He stopped the vessel immediately, and placed his son into one of the kayaks that were on board the boat, and got him away from the scene. As Operator1 tried to extinguish the flames, another vessel stopped to let his son on board. Operator1 lost the extinguisher overboard, and boarded the (good sam) boat and waited for Sea Tow. 
  
  In addition to Sea Tow being on scene, Coast Guard and Dade City Fire Boat North arrived after us. 
  
  After all had received their reports, Sea Tow towed the vessel back to Homestead. Exhaust heat ignited vapors, insulation around the engine
