i think you would be very happy with a 14 to 14.5 x 18 pitch 4 blade prop. you,ll never go back to a 3 blade prop. you can get them on ebay for alittle over 150.00 for an aluminum. or call ron hill at 1-800-762-0309 about a signature 5 blade ss prop. he can tell you which 5 blade prop to get for your boat. he sells them on ebay for 371.00 or best offer. so he would probably give you a better price if you call him.
