Hello guys, I’m new to the jet ski world. I bought a 2000 GTX Millenium edition today and took it out on the water and started riding it. Started to bog out and died on me, started it back up and gave it slow throttle and then got on it and it went with no issues. Then on the way back to the trailer it kept bogging out on me. Previous owner didn’t know much about it. Has 240 hours on it. Can it just be old gas? Any help would be appreciated.
