  • 97 seadoo gtx

    787 engine drops 500 rpm when held at about 5500...feather throttle and drop is gone....for a bit then returns...very regular....spark plugs different colours...brown/grey......thinking carb set up.also...specs say top rpm is 7200...i am at 6850....how is the rev limiter adjusted??

    carbs done...new lines,needles and jets...problem still there....hold steady throttle...and rpm drops about 500 rpms....hit it a couple of time and they go back up....hold steady and they drop again.....is the rev limiter controlled by the computer???? issue does feel electronic...almost like someone flicking a switch....also...would a faulty rectifier cause these symptoms ????????????
