    Question about a 2004 seadoo gtx throttle body

    I took my throttle body off again to check and make sure my oil pressure switch was tight because Im ocd and when I put it all back together and tightened the throttle body bolts they just kept turning. The throttle body feels like its on there tight and since theres a rubber gasket in there do the bolts have to tighten snug?

    Yes they should tighten snug. Sounds like the brass inserts in the manifold are spinning...

    you can try some epoxy made for plastic
    but you most likely end up replacing it

    Will it damage the ski riding it like this the throttle body is tight up against the manifold and the hose clamped to it keeps it from moving anywhere. The bolts are screwed in as far as they can go I dont know wtf caused all 4 brass inserts to come loose from the manifold.

    As long as there is a good seal (no air leaks) it will be fine. Just won't be fun next time u need to remove the throttle body for any reason. Over torquing is the only reason I can think of, for them to spin.

    What psycho said ... the inserts are actually pretty solid, the only reason all 4 spun is because all 4 were overtightened. Always clean the threads thoroughly and torque to specs per the manual.

    Good point ... might not be easy. You definitely may want to start looking for another intake manifold, because sooner or later you will likely need to replace it. A spun brass insert in a plastic manifold is not easy to fix reliably. You can try to put some pressure on the insert with a pliers or vise grips to try to stop it from spinning.
