Subject launched the vessel at moss lake, drove it around to the family's dock where it was then tied to the dock and engine was shut off.  When the subject attempted to start the motor again, it cranked and ran good for a minute or two, when there was a small explosion under the hood of the motor.  The two occupants jumped out of the boat on to the dock.  Fire then errupted in the motor area. That's when the subject attempted to put the fire out with two marine fire extinguishers and was unsuccessful.
 
In this boat accident, i conclude that there was some kind of mechanical failure that occurred due to possibly the age of the vessel that caused the fire.

The officer if this report did not specify the type of fire extinguishers that were used other than they were marine fire extinguishers.
