RedactedNarrative: Operator1 was operating his jet ski upstream on the Illinois River near the Starved Rock Yacht Club. The jet ski came to an abrupt stop throwing Operator1 over the handle bars into the water. The jet ski shut off due to Operator1 have the lanyard attached and started to take on water. Operator1''s friend who had been riding another jet ski in front of him realized Operator1 was no longer behind him and turned around. Operator1 was able to call 911, Ottawa River Rescue was dispatched. When Ottawa River Rescue tried to tow the jet ski it started taking on more water. It was decided to leave the jet ski tied up next to the yacht club boat ramp. 
  
  I, CPO, was notified of the accident as I began my shift. I met Operator1 at the Allen Park boat ramp in Ottawa. Operator1 told me he did not sustain any injuries from the accident. We loaded the friend''s jet ski onto Operator1''s trailer. We went to the yacht club to retrieve the damaged jet ski. Operator1 told me he did not think he struck any submerged objects since his friend was riding in front of him. Operator1 had recently purchased the jet ski and had not noticed any problems with it. 
  
  When we got the jet ski on the trailer we found several holes in the hull. Looking at the hull from the inside I saw that the hull had been repaired. The repair had failed, causing the holes in the hull.
