Testing for best performance. Between this prop the 9.25x10 and a powertech srt3 ss 9.25x9. Both 9 and 10 pitch needed to be so far down in the water to keep rpm under control, lost lots of speed in turns and both maxed out about 23.5mph at 6000rpm. This 11 pitch it's the perfect combination for my rig, planes out about 13mph, cruises 19-20mph 5000-5200, max speed 26.3mph 6000rpm. The aluminum allows a little flex to help holeshot and weighs less than the SS prop so rotates with less effort. Good buy, excellent quality
