    I encourage the wife under the ski to take a picture of the measurements this weekend in daylight for the record.

    Better late than never Ran a straight edge over the 03 and 04 hulls and re measured the hull steps

    03 = 13mm step

    04 = 18mm step

    A difference of 5mm

    My last posted measurements were obviously wrong, should have done the job properly in the first place, I was able to measure more accurately this time (off stand). There was some slight measurement changes left to right i guess the mold is not a mirror, the numbers above were after multiple measures outer edge of hull, as I move in the dimensions did decrease slightly.The above readings were in the same places. The main thing is the difference between the two rather than the exact step measurement.

    K447 said that when replacing the bearing carrier that the slop in the mounting holes can cause problems with alinement when reinstalling the bearing, so to prevent this with mine...Here is what I did. Before unbolting the bearing, I drilled 2 1/8" holes thru the top flange near the bolts, This allowed me to insert the 2 1/8" drill bits back in the holes when tighten it up and hold the alinement. Sorta like 2 dowels.

    When I did mine the guy at the shop told me just to mount the bearing carrier with the four bolts, but do not tighten them down all the way. Then reinstall all of the pump components and get that all tightened down. Lastly tighten the four bolts on the carrier and that should put it in place properly.

    I like Keddano's idea better though...

    Did not work well for me doing it that way. There is enough slop in the rubber spider coupler to allow the drive shaft to sag under its own weight. So you try to lift it up just a little to compensate for the slop, and now you are just eyeballing it or guessing.

    Get the alignment wrong and for me the result was rapid damage to the actual bearing inside the through-hull.

    K447 which would be your best recommendation when installing, as Redrum reports, or re align the pump with the right tools.

    and also as the best work of the oil seal Carrier Bearing Support, to protect that no water
