I have a 20' Lake and Bay backwater, pocket hull, 10" bobs hydraulic jackplate, 250HP SHO Yamaha, 2 power poles, trolling motor (3 batteries total in console) and usually fish the boat with a livewell full. Currently can spin a 15.25" x 25"P Bravo XS 5900-6000 rpms at 65-67 mph with 2 guys, 1 livewell full, and fishing gear. If I was going to go to a Promax with 14.5" diameter, what pitch do you think I should try? 26? 27? Mid range? Right now I have excellent mid range with the bravo XS. Should I leave things well enough alone?
