It will raise the RPM's, most likely, and maybe perform a little better when the boat's loaded. I doubt if it will overspeed when there's a light load.<br /><br />That is assuming that the two props are similar in design and materials.<br /><br />Edit your topic title, and Dhadley will probably be along to provide better information than I can give you.
