I've set up props and in some cases could not get the 15% clearance. Sometimes no issue at all. The only times it was a problem was prop noise at high speed, and that means like 25kts. Same boat at 18-20kts, prop noise was not bad at all. And this was clearance like 10%.

If you go to a 23x25, I bet you will need to knock out some pitch.

I also would not get too wrapped up in slip numbers. At slower speeds the slip will be high, nature of the beast.
