Hey guys I'm running a powertech 15.25x15 prop only pushing 5400 rpm and 36mph think diameter too much for my yamaha 200 and tritoon. thinking of switching to reliance 14.5x15 or turbo 1 14.25 x 15 too raise a couple hundred rpm... im afraid to lower pitch cause i dont want to lose any speed... any suggestions on the best prop for max mph... whether it's the ones I mentioned or another thxs
