Operator of Vessel #1 was riding his PWC north on the west side of Kettle Lake near his house.  He was traveling at approximately 45 mph.  Boat traffic was low and the lake was fairly calm.  While riding, he hit a wave.  When this happened, the PWC went left and Operator fell off the PWC towards the right.  He stayed in the water until a neighbor saw him and came to help him.  He could not get into the neighbor's pontoon boat due to his injury (broken tibia and ribs).  He hung to the side of the pontoon and was brought to shore at his residence.  He was wearing his PFD.  EMS took him to St. Mary's Hospital.
