    sounds more like spark plugs you really have to differentiate and vibration from an engine miss..

    i dont know if its the plugs for sure nic i remember the first time they went out the ski would not even go over 35 mph and i could tell it was misfireing and no vibration ive never felt the ski vibrate like this specially at idle and takeoff but i will def check them out ill have to wait till tues cause theres only one place where i live that even sells those plugs can the bearing still go out even with the mod? just feels like thats where its at to me

    Yes it possible for the bearings to fail still especially if installed poorly. Have you checked your sc belt.

    The belt can stretch over time. Especially when first installed. A slipping belt will cause allot of vibration also. Not saying this is your issue but don't rule it out. Did the ski make boost during your issue

    Sounds like something with your pump has or is going bad be it prop or bearings etc.
