RedactedNarrative: I arrived on scene at approximately 8:49 P.M. to find a burnt PWC 3/4 of the way submerged under water. I spoke with a couple witnesses on the dock and determined that when the PWC exploded, several bystanders obtained several fire extinguishers and proceeded to spray the burning jet ski. 
  
  	I later determined that no one except the operator of the PWC was injured from the incident. I spoke with Operator at the scene to determine his condition. While speaking with Operator, I could smell the odor of an alcoholic beverage coming from his person. I asked him how much he had to drink and determined that he had drank two "Lake Waters." Due to his condition, Operator was then transported to Gwinnett Medical Center in Lawrenceville. I obtained 4 witness statements from the scene, then I went to Gwinnett Medical Center to interview Operator. 
  
  	Operator stated that he had driven the PWC to Holiday Marina to eat at the Twisted Oar. After he ate, he went to the PWC to start it. He untied the PWC from the dock, hit the start button and nothing happened. Operator then primed the PWC and hit the start button again. The PWC still did not start. Operator tied the PWC back to the dock and primed the PWC again, he attempted to start the PWC again with no luck. Operator then primed the PWC for the third time, he then hit the start button again; it was at that moment, the PWC exploded throwing him approximately 20 feet in the air (per witnesses). When Operator came down, he hit his face on the dock with the rest of his body landing in the water. Nearby bystanders, helped him out of the water and to safety. 
  
  	After speaking with Operator at the hospital, I determined that he has had this particular PWC for 20 years. Operator does all the maintenance on the PWC himself. Recently, Operator had worked on this PWC by installing a new primer kit on the PWC. I also determined that he was wearing his life jacket at the time of the incident. 
  
  	Based on my knowledge, training, and experience, I believe that this incident occurred due to the engine system and fuel system causing the gas fumes to ignite. As a result, the PWC exploded, throwing Operator off the PWC and resulting in the PWC to catch fire. Operator sustained a couple broken ribs, and lacerations to his face.
  
  	  I do not believe that this incident occurred due to Operator consuming a couple alcoholic beverages.
