Joker, these are deep V hulls, which means there is a lot of planing surface on the water which means resistance...IMO they need a large diameter prop to get all the push against that resistance...I used a 15 1/4" x 17 for that reason and was completely satisfied that my motor was getting all the prefomance possible on that hull...The only reason I didn't use a 15 1/2" diameter was that it was a little too heavy and caused a rattle in the lower unit, but your motor should handle it...you didn't mention SS or alum...use SS for best performance...hope this helps you find the right prop...sometimes it's not easy...
