I'm pretty sure I'm spinning my 9/15 prop in my 735cc freestyle port 701/ X2. FP exhaust. lighten flywheel MSD I installed a intake grate but I'm not feeling the ski hook water until it reaches some decent speed. Actually this ski is fast in the mid and top end but if a 9/15 was meant for low end I'm not feeling it. I think I have more motor than prop. What is another option?
