Have a 175 ProXS 4 stroke on a 6” manual jackplate. Ran 61.5mph at 5850 according to tach with full fuel and me alone empty livewell. With another passenger ran 58.5mph at 5250. I’m spinning a 22 Tempest but I haven’t yet measured PTP. I get about 25psi water pressure at WOT. I’m hoping I can keep the 22 Tempest but I’m wondering if anyone here has suggestions for PTP measurements or prop suggestions. I’d like to get more speed but I also think I probably should be running in a little bit higher RPM range.
