Hey,I have a 1963 Johnson 28HP.I pulled the prop today and got the numbers off it and found one here on this site I may buy.My question is the one I pulled off says 10 3/4 X 11.The one Iboats sells here and the one the manual says it is supposed to have are the same specs 10 3/8 X 11 1/2 I assume the one on there is not original maybe as both my manual and the Iboats one is the latter measurements.Now my question is whats the differance in the performance of the two differant sizes?My HP is rated at 4500 RPM.Which one is best do you think? Thanks
