    More cavitation than stock?

    I recently put on a R/D intake grate and PPK on a FZS, and there is now more cavitation that stock. The grate was tightened to spec and pushed as far back as it would go. PPK was heavily trimmed because the pieces needed a lot of force to keep flush, and I didn't have the leverage under the trailer to force it back and get the bolt holes to line up. The ski was also unhooked more easily over slight chop...

    I also installed a FF at the same time. I didn't figure that it would burn up the prop with just that, but could it be just prop spin and not cavitation?
