RedactedNarrative: Vessel – 1998, 10’’ Kawasaki Polaris SLTX PWC w/1 Polaris Gasoline Inboard Engine – 100 HP 
  
  On 07/29/2018, at about 04:58 p.m., this vessel was docking/undocking on Mason Lake at the Mason Lake Public Boat Launch located near Allyn, WA in Mason county. 
  
  According to Law Enforcement, on this date and time, Officers were dispatched to this location for a report of a water-related incident.  They were advised that a male subject was on a PWC at the public dock and the PWC exploded, catching fire.  It was also indicated that the male had possible injuries.
  
  Upon arrival, Officers were given a list with the victim’s name and the names of witnesses.  They were advised that Fire/Medics had transported the Operator/Victim to Mason General Hospital.  Officers observed two PWCs near the public dock, next to shore which included the one that had exploded.  There was a large oil sheen on the surface of the lake that was spreading wider due to a high traffic volume of boaters coming to the ramp to take their vessels out on the water.
  
  Officers spoke to one of the witnesses, Operator’s friend.  He told Officers that Operator had bought the two PWCs about one month ago.  The maintenance history was unknown.  The seller had told Operator that the PWCs had not been operated in 5 years.  Operator’s friend said that he and Operator launched the PWC here, at Mason Lake.  He said that Operator’s PWC was sputtering and cutting out and finally died.  They towed the PWC back to the dock and tied it up.  
  
  Operator’s friend said that he left the dock to take a ride on his PWC.  Within a few minutes he heard a loud explosion, looked back towards the dock.  He observed everyone running around the dock and realized that the explosion was from Operator’s PWC.  He immediately returned to the dock to assist.  He could see that the PWC was on fire and that other people on the dock were using their fire extinguishers to help put out the fire.  He could see that oil was leaking out of the PWC.
  
  Another witness said that she was sitting on her pontoon boat that was parked behind the PWCs.  She heard one of the PWCs start up and then she heard a loud boom.  She said that she looked up and saw a man (Operator) fly 10 to 15 feet in the air landing back on the PWC.  She said Operator landed on his neck and shoulder then fell into the water.  He then stood up, walked over to her boat and sat down.  She said that they used the fire extinguisher from the pontoon boat to put out the fire.  
  
  Law Enforcement received authorization to take Operator’s PWC to be inspected.  They asked Operator how many times he had operated this PWC and he reported about 12 times.  He indicated that the vessel had run really well the last time he was on it.  He said that he had recently changed the spark plugs and that it is not modified at all.  He said that he had fueled it up in Port Orchard and couldn’t understand why it would have vapor in it.  
  
  Officers told Operator that when operating a PWC, you should open the compartment first to let it vent.  Operator said he always does that.  Officers advised him that witnesses reported that he didn’t this time.  Operator agreed.
