Operator of V1 was jumping wakes with a PWC that he borrowed from a friend. Upon seeing that he was getting close to a no wake zone underneath a bridge, he began to slow his PWC. At the same time, he looked back to see what his friend was doing and hit a wake he didn't see. The victim struck his head on the steering column of the PWC rendering him self unconscious and falling from the machine into the water. The friend rode up along side the unconscious victim & turned him on his back & held his neck.  A pontoon assisted by transporting the victim.  The victim was wearing a lifejacket.
