RedactedNarrative: At approximately 2:23 PM, 13yr old was operating a PWC by himself on the Fox River just north of the Algonquin Dam.  His uncle was on a 2nd PWC riding with him.  (he owns both PWCs)  O1 was travelling southbound on the river when he attempted to jump a wake and lost control of the steering.   O1 made a sharp right turn and crashed directly in to a steel seawall.  O1 was launched forward and broke the steering counsol with his chest.  O1 suffered minor brusing and injury to his chest and thighs from the impact as well as a minor wrist injury.  O1 believed he was travelling approximately 20 mph at the time of the incident.  O1 does not have a safety certificate and has only operated a PWC on one other occasion.  O1 stated he was having difficulty breathing after the crash and was transported to Northwestern Medical Hospital in Huntley for evaluation.  CPO met with him at the hospital.  He was evaluated and discharged without treatment.  No injuries were discoved at the hospital and the breathing difficulty was likely a symptom of shock from the crash.  O1 recovered the damaged PWC (photos attached) and will be submitting a claim to his insurance company.  Estimated damage to the hull and steering consol is $2,000 +.  No other private property was damaged in the collision.
