I don't mind loosing 2-4 mph but it would concern me if max speed dropped to the mid-hi 20's . Anyone have any info on this?
Yes, I have the 19 SL450 with 1.76 and 16x15 prop. I'm at 2200' elevation. I'd really like to try the 16x17, because the rpms are around 3600-3700 at 11.5 ballasted and surfing. But it's not worth $700+ just to try it.

Top speed for me empty was 36.4mph at 5350rpm.
