RedactedNarrative: Owner was on his 36' ft cabin motorboat while it was moored at the Newport Marina.  The day before he had installed a new water heater and shower pump.  While he was showering he heard something.  When he came out of the shower he saw there was a fire on the boat.  He attempted to put it out using the fire extinguisher but the fire extinguisher failed and the flames and smoke quickly overwhelmed him.  He exited the boat and attempted to use the fire hose located on the dock.  
  
  When operator was unable to put the fire out he noticed it was calm with no wind.  Knowing the boat had about 65 gallons of fuel and 2 propane tanks on board, he cut the mooring lines, jumped into the water and swam the boat out away from the marina.  the Mercer Island Marine Unit arrived to put out the flames but the the boat was already burned to the waterline and sank.   The owner had minor burns from his attempt to put the fire out but was not taken to the hospital.
