RedactedNarrative: On July 29, 2022, I Officer 1 received a phone call regarding a PWC that was sinking just past the Starvation marina at 1028 hours. I drove down to the boat ramp and saw about 7 inches of the vessel bow (yellow in color) visible above the water surface in a vertical position. There was two people in the water tying lines on the machine. there was also a recreation boat and a second yellow PWC in the area. I notified dispatch of the incident. The sinking vessel was operated by Operator. The nearby recreation boat was able to tow the PWC to a jetty on the west end of the boat ramp. I was able to get a hold of the tow line and walk the PWC to the wedge dock, while Operator and another male individual were able to wade along side. 
  
  The PWC was placed onto the trailer and pulled out of the reservoir. An excessive amount of water flowed from all of the through hull fittings in the stern section of the PWC. I was able to verify that the PWC had a bilge plug in place. I also examined the entire hull of the PWC for any cracks, punctures, or flaws on the hull. I didn't find anything wrong or deformed with the hull/body of the PWC. I asked the operator for an account of what happened. He stated that he launched the PWC and just as he got to the no-wake zone boundary he noticed that the PWC had taken on a lot of water quickly. While examining the PWC I believe that it possibly may have been an issue with the neoprene seal on the propulsion system. The engine and other internal compartments recieved damage from water exposure. 
  
  I performed a vessel inspection and then documented information for report. there were no injuries or additional damaged property. 
  
  No further details
