HELP!!! replace REB prop with racin cleaver outboard?

have a 1996 Evinrude 88 SPL 2 stroke V4, and im wondering if replacing the stock REB prop with a cleaver racing prop would harm it or mess with the exhaust or have any cons with it. It is a 13 spline and im looking for a 26 - 28 pitch 13" - 14" in diameter racing cleaver prop. From my amiture thinking i would think replacing the REB prop with a cleaver wouldnt have any cons EXCEPT maybe how the water flows to the prop. Would the exhaust get in the way making the prop catch the exhaust fuems wich would make it not perform its fullest performance? I dont know im leaving it up to you guys, please help me!!
