On the said date and time, Operator was setting alligator lines on Lake Texana near Ganado, TX.  Operator stated that a jet ski came by his location on the lake and was throwing up a rooster tail behind it.  This rooster tail of water went in the direction of Operator's air boat.  The water went into the fan breather of the Operator's air boat.  When Operator tried starting the engine he heard unusual motor sounds coming from the engine and could feel the engine shake.  Operator shut off the engine at this time and called for someone to come tow him in.  After looking at the problem, it was determined that the water from the jet ski caused Operator's engine to hydro-lock.  This also caused one of the pistons to disintegrate causing the parts of that piston to distribute throughout the engine causing engine failure.  Operator was not able to make contact with the jet ski that caused the rooster tail nor was he able to obtain a registration number from the vessel. End of report.
