With only a little information anyone can be dangerous.....<br />I went looking in the catalogue for Michigan wheel and it showed a 15" diameter prop referenced for a mercruiser 470 engine. So I bought it used, $$CASH$$. (Nice and Shiny SS 17 pitch) I find now that it would hit my standard trim tab. Now I do see a high performance rated trim tab (822777Q1) that seems to be set back. Any one know if this would work or reason not to use the 15" diameter prop???
