This 'simple' question is getting WAY too complicated for a basic mind like mine. IMHO...I had a 20" shaft and found that even motoring into waves that at times were quite large...I experienced only VERY minimal cavitation. 20" is fine in my books...it works!!
Back to basics. Yesterday I took the critical measurement. I have 15-16 inches from the water surface to the center of the prop. My engine has cavitated a couple times in high seas. If I had a preference, I would put it in the 17-19 inch range.
