Operator was operating a 14ft Alumnacraft vessel, equipped with a 20 Hp Mercury in the area of Miller's Bay Cove on Toledo Lake.  Operator and his son were pulling a person on a kneeboard.  Apparently, the operator was making circles while his son was sitting in front of the vessel as they jumped their own wakes.  his son moved to port side of the vessel, the same side as the operator causing it to throw both subjects into the water.  Subject who was knee boarding, let go of the rope and started swimming.  The vessel was out of control and making circles due to the fact that he did not have a cutoff lanyard attached.  At some point the son and the kneeboarder were both struck by the vessel causing injuries.  The vessel continued making circles until it ran out of gas.  A 12 year old neighbor observed what had happened and picked the subjects up out of the water with his father's boat.
