Hi everyone hoping someone can help me figure out what’s going on with my seadoo. It only has 130 hours and has never given me a problem before. I went out on the lake one day and it started fine but when I went to give it some throttle it started misfiring and sounding really rough. So I assumed I sucked up some weeds and when I took it out it had weeds in the intake so didn’t think anything of it. Well it’s still doing the same thing after cleaning it out and taking the back end off and inspecting the propeller. Checked compression in cylinders and I got 117 117 and 110 in the first cylinder. Spark plugs did have some oil on two of them as well, and I noticed the oil on the stick was on the top line. Still starts up no problem and runs but as soon as you give it throttle it starts sounding like shit and won’t fully rev out.
