Not too long ago, used 87 for a couple fill ups (didn’t know it mattered) after a while it then suddenly shut off and ran weird… after that, used sea foam and the right gas and after that it ran great full speed for probably 7 hours. Now my warning beep keeps going off after 30 minutes of riding and starts to run differently. If I let it set for ten mins it starts back up and runs fine but then acts up again shortly after. Not very experienced with taking care of jet skis so any advice would really be appreciated. Thanks.
