Operator rented a 2003 Yamaha PWC, IA registration 2714BC, and was operating the PWC with his son, as a passenger.  Operator drove the vessel in circles and they both fell off the PWC.  As they were falling, Operator's head hit Occupant in the shoulder, hearing a loud crack sound.  Once in the water, Occupant complained about his ankle hurting.  They got back on the PWC and returned to shore.  Occupant was complaining about his shoulder as he was walking on shore, he felt light headed, sick to his stomach and blacked out.  As he blacked out, Occupant fell to the ground and landed on the sidewalk.  Occupant was transported to Lakes Area Hospital, treated and released.  Both Operator and Occupant were wearing PFDs.
