RedactedNarrative: On 8/3/21 at around 1400 operator was on his 2019 Bombadier Jet Ski in the Ogeechee River near Fort McAllister boat ramp. He was accompanied by subject1 who was on a Yamaha Jet Ski. The two were riding around jumping wakes when Operator noticed that his Jet Ski turned off. He cut it back on and it shut back off and repeated this multiple times until the Jet Ski cut off one final time and when Operator attempted to start it back up he observed smoke. He opened the hood of the Jet Ski and that's when the Jet Ski caught fire. Operator Jumped in the water and hopped on the Jet Ski with West. They alerted Bryan County Sheriff's office and rode back to the boat ramp. When I arrived on scene Bryan County Emergency services and the Sheriff's office was already on scene. Nobody was injured and the Jet Ski burned up.
