    PUMP SHOE NOT ALIGNED ON GPRS WITH THE 2'' EXTENTION

    This is an 05' from the factory.

    You can clearly see the step "down" out of the pump shoe onto the extention.

    How do you remedy the situation? Move the Transom Plate UP ?

    No Billy..we are gonna do nothing, it would require hull inlet work (fiberglass) and transom work. I am thinking of putting a different pump shoe ('01) to see if it still has the gap. This is the gap that I described earlier.

    the pump shoe is bolted to the bottum of the hull so moveing up the transom plate will help a little, but will not close the gap they are made that way someone posted one time it is designed to help keep from over loading the pump I don't know?

    what I have done was plain about eighty thousands off the bottum of the pump shoe at the back with the idea of shimming it down to match also looking for more speed I didn't get to test it I got off to late and it was the last time I rode it this season I did ride with it like that but got to dark on me to do any shimming the pump wasn't sealed so it spun badly out of the hole but stuck to the water in turns top speed was about the same couldn't tell any or enough change from last time i was out (I also raised my ride plate up on all four corners to keep the same angle with the shoe when testing)
    I need to work on my plate some more because there is some gap that needs to be closed it a stage two Iland Raceing plate I can't wait to do more testing but would have to chop ice to put my ski in and even with a wet suit would frezzzzzzes things I still want!!! I think there is more speed to be had from the shoe!

    why are we sanding and block sanding everthing with six hundred grit if that big step doesn't matter?

    thats how they all are on 05 and 06

    I used ppk shims and found alignment perfect but lost top end speed as shoe hangs lower than hull

    exactly, trying to fix this may cause more problems than remedies.....unfortunate as of right now.

    It is like this on both my 2002's without pump extention. Pistonwash brought this up about 4 weeks ago.

    I'm sure it can be fixed, but I don't think I'd go there without major bucks in hand.

    Plus, if work ever starts on the 158mm Skat pumps, this will work out even better.

    why would it be exspensive?

    all you got to do is rework the pump shoe weld the voids full and grind it down flush,or eaiser yet fill them with J. B. Weld and grind them down

    I will end up with an extra shoe so if putting shims under the back bolts of the one I machined down don't work I may fill one with weld and machine the top down to fit.

    also on a side note has anybody ever taken some fiberglass filler of some kind and mated the shoe to the hull sanded it down smooth and painted it?
