RedactedNarrative: On 9/16/2017 at approximately 12:41 pm, owner, operator, and victim was pulling his Jet Ski out from his boat slip near Camp "O on Lake Delhi. Upon exiting his boat dock, Victim first started his jet ski and was floating about 20" away from the hoist with the engine running when he immediately had acceleration/throttle issues.  
  As Victim attempted to throttle up or accelerate, simultaneously an explosion occurred under the seat and blew the front end off of the Jet Ski.  As a result from the explosion, Victim was ejected into the air (approx. 20 ft), and landed back on top of the burning Jet Ski.  
  Victim jumped into the water and began yelling for help. The Jet Ski continued to burn as Victim tried to swim to shore. Nearby residents assisted Victim back to shore where he waited for medical help and treatment.  The fire department arrived and pushed the Jet Ski away from shore while they extinguished the fire.  The Jet Ski later sank.  
  The victim states the Jet Ski was in great mechanical condition, and had always run perfectly.  No engine work or rebuild had been performed.  The victim stated he had just completed installing a new floating bearing for the impeller and noticed while the plug wires were disconnected that they arced together. He inspected the wires, they looked to be in good condition.  He then reconnected the plug wires to the plugs, and ran(idled), on the trailer. He thought it seemed to be running OK and he did not notice any arcing between the plug wires.  After putting the Jet Ski in the water, it would not accelerate. 
  The Victim was wearing his life jacket.  His injuries included: shattered four(4) lower lumbar spine vertebrae, broken ribs, dislocated shoulders.  He is anticipated for a full recovery. No alcohol or drugs were used.
