ILR,
Did you ever pick up an Indigo prop?
With a clean prop & timing adjustment (reset from scratch actually
) I was able to get 2,300 RPM WOT this weekend..that is 150 more than I could get last year.
I even did some sailing this weekend, and I agree that the additional drag is negligible compared to a 2-blade fixed. The prop is so tiny when you install it you won't believe it!
