jipster43, jefflyman, Whats up guys, it's Jason (DooSPX) from TeamTalk. I feel you need to call Eric from OJ, he will set you up. I know the CNC XMP 4 blade OJ 13.7x17.5 .110 cup on my Powerslot, made a HUGE difference in every way. with my 240hp, it has MUCH better holeshot, actually gained a tiny bit of top end, holds speed like a vice- even with my hardest pull, and softened the wake and bump too. Plus Eric will let you try before you buy. I cannot say enough about Eric or my prop. Stand up guy, answered all my stupid repetitive questions and we shot the sh** too.
