RedactedNarrative: According to the operator, they were transporting v1 to dan's marine to be dry-docked for fiberglass work. While in transit across the lake the main engine began to overheat so he shut it down and attempted to start the second engine.  The second engine would not start. While inspecting the engine, the operator noticed a fuel leak so he made repairs to fix the leak.  The operator asked his passenger to try and start the second engine again but it would not start. The operator then "wiggled some wires" that caused a spark which ignited the spilled fuel and vapors.  The operator attempted to put the fire out with an extinguisher, to no success.  V1 quickly became engulfed and both the operator and passenger bailed overboard.  They were able to make it to the shore and call for help.  V1 burned to the water line and was a total loss.
  
  A visual inspection of v1 after recovery revealed: there were 3 battery terminal wires that were not hooked up to the batteries. There were also multiple wires that had been cut in front of the starboard motor but it could not be determined where these wires went or what they controlled.
