Coincidence is powered by a 3GM30F Yanmar with a 1 1/8 shaft and a Kanzaki, KM3P Mechanical gearbox. Serial no(s): 17745. Gear ratio: 2.61:1 I recently purchased a 2 Blade 17 inch Max Prop. It comes with a 22 degree pitch. When I was communicating with PYI they had recommended a 2 Blade 17 inch 20 degree pitch if I went with their new propeller. Does anyone have any thoughts/experience regarding 22 degree pitch vs 20 degree? Thank you, Blair Coincidence 1990 C&C 34 +(902) 233-1684
