Pump support question

[icdoo]

Doing major overhaul of bottom end of ski this winter and noticed on the support, where the pump actually seals, is somewhat out of round and the mating surface is anything but flat. I can't imagine it creating a good seal to the pump. Has anyone noticed this on others? Put a new seal on pump only a few hours ago and it already has spots where it is deformed from not seating properly.

Take some pics and post it may help us see what your seeing.

Don't think you could see in pic. I can run my finger around the sealing surface and it is very lumpy. I could try and smooth it out with dremel, just wondering if this is typical and if I should even bother.

The seals are pretty forgiving, it would be hard pressed for me to believe the support could be that far out of whack..

Thanks for the input. Just trying to cover all the bases, have some speed issues and I think some are due to cavitation.

Wear ring, prop dammage, carbon seal and accordian boot may also come into play when chasing a cavitation issue.

Going through with a fine toothed comb right now. This was just the first stop

Never really acted like cavitation but had some pitting on the trailing edge of prop. Was leaning more towards shoe and engine alignment, Going bigger everything this winter and want to make sure everything is good as I go.
