i removed my 2 blade maxprop to change my cutlass bearing, i knew that i wanted to save the settings but was unable to because who ever install it had one blade on upside down! on the attached site it gives the settings to install the prop. my question is; what was the original prop?there is much talk about how hunter changed engines and such. my engine it the yanmar 3 cylinder, 20 horse. i beleive the prop should be the 15 degree. but i should ask the experts. what do you thinkcheers,mike
