My 1985 Mecury 18hp has a really worn-out prop on it now.I have not ran this motor in the water yet since I just rebuilt most of the issues it had when I traded for it.I have it running ok at the time.Just no water time cause the prop is in bad shape.It has a 8 inch 13 pitch on it now...not sure it's the one that came on it.....Question is can I put a 9.5 pitch propeller on it? And what will it change.Oh the new prop is also 9.5" in size also.Will it work ok? Thanks for any advice!
