    Bone stock. Hes cavitating a lot in surf with an aftermarket small hub prop and wants to try to fix that with the mag pump. I may bump the low speeds up one half size as well.

    I believe he has an intake grate and possibly a ride plate also. Cant remember as I havent worked on the ski since he got it two years ago.

    Call Dave a impro's let him know what's been done to the ski and he'll fix you up. I've got 3 through him and always been satisfied.

    Re: GP 760 prop selection

    I dont think an impeller will fix the issue. I feel like a good sealing of the whole pump and tunnel along with tight impeller clearance will take care of it. Is the impeller hoising shot?
