    Need some Pump Shoe Install Guidance

    I dry fitted my pump shoe in place this evening to see how things would line up...

    PPK is grinded really smooth everywhere, all brand new updated brackets inside the hull, no obstructions or silicone overlooked...

    i'm falling a bit short of getting a nickel under the straight edge

    recommendations?

    anyone have a picture of their pump shoe / transom plate area taken from the rear of the ski with no pump? ... the pump shoe comes up into the transom plate opening a bit.. meaning lets say the diameter of the transom plate is 155mm.. well the pump shoe semi-circle comes up higher than the transom plate opening effectively making it smaller...

    all this the meanwhile, my pump shoe still isn't even high enough up into the hull since i cannot slide a nickel under a straight edge neither at the front OR rear of the pump shoe

    please point me in the right direction

    THANKS!!!

    STEVE

    Shave a little off the pump shoe where it meets the hull until you get the desired measurement. I also measure mine on either side where the angles are to make sure everything is true and inline. Measure front and rear

    I sprayed mine with primer to show the low spots then trued the bottom surface. Then I fit in the hull and trued the mounting surface until I got it even. I did all this with a hand file

    the step is normal. you may need to sand down the paint under the shoe to get everything up high enough. measure with the straight edge across the bolt holes. should be a loose nickle. duke's gallery has the best pics of this.

    good pics, thanks guys...

    it may be very possible i'm missing by exactly that mike... the thickness of the paint. the nickel is close, but not quite there.

    same step at both the front bolt hole and rear blt hoel, or different step/taper is recommended?

    now where is a good place to take measurements to ensure the shoe is not crooked or that it's not favoring one side of the hull?

    thanks a million guys!

    I measure both sides thru the bolt centerline. Check front and rear of shoe, front is usually about 10 thou higher in the hull then rear.
