What numbers are you getting from the existing prop...  ...if it is getting the max rpms your motor's specs allow, and not causing any difficulties, you may already have the right one...Post up some numbers rpms/speed @ increasing rpm range 2000, 2500, 3000, 3500, up to mfg's max rpm for us if you can...top down, light load, slick water, etc... If you haven't gone through this test w/existing, you may not need to change props...

4 blade props do lose a little top end, much the same as a large diamter 3 bladed prop does. Modern 4 bladed props do alot better than old ones did. It all boils down to the boat and the application. I know my flats boat would only get to 52 with any 3 bladed prop I tried, but the 4 bladed TROPHY plus I put on it hit 61 and was still climbing when the wife smacked me and said enough(sold it before I had a chance to see just where it would top out). And most of teh time what you lose in top end with a 4 blade, you make up for with improved hole shot and mid range cruising.
