    Pump shoe alignment

    Can the pump shoe be set back all the way untill it hits the transom plate?
    There is about 1.00-1.300" difference from the stock setting to the back of the transom plate. This will close in the gap where the shoe and transom plate meet. Any testing done on this re-alignment?

    I've heard of this being done, you have to slot the mounting holes. Can't tell you how it might work?

    Hey dave yes this does work well you will have to reset your handling again but you can get more speed this way Remeber you will have to work on your intake grate holes if you move that pumpshoe that far back. This also helped with the buck on one of my skis

    Just a question. If you elongated the shoe mounting holes and moved it back to touch the transom plate, would'nt that effectively close the gap between the rideplate and the pump shoe resulting in the problems mentioned in the other recent thread "shoe sealing question"?

    My gap between the back of the shoe and the front of the ride plate is only .080 as it sits now (shoe pushed back but in stock holes).

    Mine had a slight gap still between shoe and plate. I have never sealed that gap before so I cannot comment on if it works or not If your going to reseal the shoe I just recommend to leave the holes alone and when bolting it up push it back as far as it will go, trust me there is some play there by the thousands

    It only makes since to have the shoe as far back as possible. I also have to macke sure the shoe is up in the hull as well. Seems like a 1/8" gap from the soe to the transom plate. What kind of gain should be expected with the shoe all the way back. I am looking for 2 mph somewhere? I noticed my shoe was bolted straight up and not back. Will post results this weekend without being sealed. Thanks for the help.

    Dave depending on if your shoe was hanging down and you lost mph. If that was the case you will see huge gains if not you will have to play with the adjustment of the tabs and plate to see your best gains do not tuck that shoe to high

    Now it seems I have to raise the transom plate by shaving the stoppers to reduce the lip inside the tunnel where it meets the transom. Is raising the transom needed also???
