We need to get together, I bet we can figure it out
Both original and XS say "Bravo1" on the side. If it is a full flare prop, then the PVS were added and you should be able to start plugging holes farthest from the gear case until is has no spin. Mine had 1" holes with NO spin, where the XS version with same holes spun terrible. I have pics of both side by side if someone would post them for me.
Save yourself a lot of time, and money and put a foil on it. It’ll be a different boat out the hole with it. You’ll wonder why you waited so long to bolt one on.

I fought it for a few months when I bought my sf. Finally put the foil on it and I went from hating my boat to enjoying it again. The sf porpoises like a stroker to me. The foil eliminated almost all of that as well
