    FZS Riva Stage 3--Loud vibration when turning hard

    I'm noticing a loud vibration coming from the right side of the hull when I cut hard to the left with throttle on. It doesn't happen when turning right, but it sounds like something is contacting the hull under the centrifugal force. Any thoughts?

    Riva powercooler? I'm pretty sure some have clearance issues.

    +1 yes exactly my thought.. the BOV doesn't have enough clearance causing it to rub against the hull

    Well if it turns out to be the powercooler/BOV There is a way to modify the IC mounting bracket to give it more clearance. I may be wrong but I think Craig did this on his ski.

    Thanks for the input, I'll check it out.

    Checked it out, there is substantial wear into the hull just adjacent to the BOV--mystery solved. Thanks again.

    Its an easy fix. Just hog out the IC bracket holes and twist your BOV away from the hole a bit. As you tighten the IC bracket bolts, pull the whole setup away from the hull. Mines been fine since I did that.
