RedactedNarrative: On 08-27-17 at approximately 1156 hours I was dispatched by MCSO Radio to a watercraft fire at Saguaro Lake.
  
  
  Upon arrival I found the watercraft at Boat Ramp #2, sitting on the ramp on fire from bow to stern. All the occupants were out of the watercraft and there were no injuries. I spoke with the owner''s son, who told me the following; he started the watercraft out of water to make sure everything was working properly. He does this every time he comes to the lake. He had the blower running and shut off the engine. He launched the watercraft and his friend attempted to start the engine. There was a large explosion, blowing the engine cover off the stern of the watercraft. The engine compartment caught fire and the three occupants seated in the bow seating as well as the operator jumped into the lake. They swam to safety with no injuries.
  
  
  Personnel from USCG Flotilla 10-11 arrived and extinguished the flames using a gas powered water pump. Rural Metro Fire arrived and sprayed foam on the watercraft to cool it off and prevent any flare ups. 
  
  
  The watercraft was recovered from the water and towed on a flatbed from the scene by All Pro Towing.
  
  
  Body worn camera activated during this incident.
