RedactedNarrative:       On 06/25/2016 at approximately 5:01 pm I was dispatched to Green River Marina in reference to a sinking SeaDoo. I arrived on scene at 5:34 pm, where I interviewed  subject at the Green River Marina. Subject stated that he and his friend had rented a couple of jet skis from Wet-N-Wild Motorsports Inc.  
  
  Subject stated that he was operating Vessel 1 (KY-0679-AM) when the motor quit running.  Subject stated after the motor quit running he got on the other rental jet ski with Subject2, and they returned to Green River Marina.  Subject stated that he notified the women that he had rented the jet skis from of the occurrence. According to Subject statements at this time the women went to look for the jet ski. Employee was gone for about an hour before she returned to the Marina. Unable to locate the SeaDoo, Employee then takes Subject with her to the exact location. At this time according to Operator1's statements the boat was beginning to sink.
   
       After the interview with Subject, I was able to interview Employee, an employee with Wet-N-Wild Motorsports Inc.. In a written statement, Employee states that the two SeaDoo's were rented at approximately 1:00 pm, the party brought back one Seadoo at approximately 3:00 pm. At this time the party stated that Vessel 1 would not crank, so they left it on the water. At this time Employee states that she went to look for the SeaDoo, but was unable to locate it so she came back to the marina and picked up the members of the party. Subject then took Employee to the exact location. Employee writes that when she located the SeaDoo it was in an upright position and sinking. 
   
       After interviewing both parties at approximately 6:18 pm, I was able to locate the SeaDoo at approximate G.P.S Location N37 17' 47.44" , W85 16' 24.35". At this time only the nose of Vessel 1 was above the surface of the water. Green River Marina employees arrived shortly after and pulled Vessel 1 to Smith Ridge ramp where it was loaded on a trailer. 
  
       Once Vessel 1 was trailered and pulled from the water, I observed a lot of water escaping from the bottom stern side of the vessel. I photographed the vessel 1 and cleared the scene at approximately 06:49 pm. 
  
       I continued the investigation on 07/01/2016, with a telephone conversation with a boat mechanic at Personal Performance in Russell Springs.  The mechanic advised that he had looked at Vessel 1 and based on his observations the following occurred. A lot of rock and gravel was sucked through the jet pump impeller, causing the pressure that is produced by the jet pump to be reduced. The same jet pump is also used to keep the exhaust cool, and when the pressure was reduced the exhaust got too hot. As a result the plastic around the exhaust was melted which allowed water to start entering the hull of Vessel 1, causing it to sink.
  
       Based on my investigation I believe that all statements given by all parties involved are truthful. Subject left Vessel 1 on the water in an up right position near G.P.S Location N37 17' 47.44" , W85 16' 24.35" after the motor had quit running. At this time Vessel 1 was most likely taking on water, but not enough water had entered the hull to cause it to sink. At some point between the time Subject left Vessel 1 and the time Employee located the Vessel 1, the vessel had taken on enough water to cause it to sink. I can not determine as to when the rocks were sucked through the impeller which was the primary cause of damage. 
  
  *** No one was injured as a result of this accident. Damage to Vessel 1 is estimated at $2500.00.
