  Vessel 1 Operator Report:  Boat was at the end of the trail from our campsite on Black Lake.  Went down and put about 4 gallons of gas in boat around 5:45pm.  About 5:55pm myself, my son, and my father-in-law boarded the key to start the boat.  The boat started, then shut down.  I let the blowers run another approximately 30-60 seconds (they were never shut off) and tried to start it again.  There was a big bang and blast from the engine area of the boat.  My son ran to the front of the boat and said he was hurt/burned.  I went to the engine compartment to see what was going on.  It was on fire.  Started bailing water from the lake with a 40 quart cooler to contain the fire until the passengers were off and away from the boat, the fire extinguisher was in the fire and not accessible.  At the point in which the passengers and myself jumped overboard, the boat was approximately 100 yards offshore.  When it became fully engulfed, it drifted about 100 yards down the lake, and back closer to shore where it came to rest and the Sawyer County Fire Department extinguished the fire.
