RedactedNarrative: The operator/owner of this vessel was out on Whitney Pond in Oxford, ME with his 10 year old daughter when the vessel stalled out. When he attempted to restart it, the vessel exploded launching both operator and his daughter up into the air where they landed in the water. Both subjects were wearing USCG approved life jackets at the time and neither one was injured. 
  
  Another boater came to their aid and their vessel was towed to shore. Upon examining this vessel, it was found that a newly replaced fuel injector had fallen off due to a broken mounting bolt. When the fuel injector came off, fuel was pumped into the hull before the engine stalled out. 
  
  When the operator attempted to restart the engine, the vapors inside the hull ignited resulting in an explosion. The upper deck of this personal watercraft was separated from the hull and a front hatch was blown off. There was no fire after the explosion. The owner stated that he had purchased a replacement fuel injector and a friend of his who was an automotive mechanic did the installation.
