i am experimenting with other props on my Evinrude 200 Ram Ficht. I am having good success with some mercury props. I bought the adapter kit and notice that the diameter of my OMC Renegade 27 BASS is 13 1/2 inches and most mercury props are significantly larger in diameter with the Bravo 1 being 15 1/4. Why are the OMC props smaller in diameter? Is there any reason why I should not run other props on my Rude to try to find the best combo for my Gambler bass boat? Thanks !
