Re: s.s.prop size
I'm running a 15 x 17 stainless on my V20 with a 225 Johnson and get 5600 RPM at 47 to 50 MPH. So i would say a 17 pitch most likely for a 150 as well. you can run a 15 pitch and gain 200 to 250 more rpms than the 17 pitch but it will slow you down about 5 mph but give you more take off power with faster plane. good luck
