Re: s.s.prop size
 

I think 14.5 to 15 about 5400.

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

Hey Skool - Welcome to the site :D It's me, Shane from Lexington.

You didn't even know this little world existed did you ;)

There's a lot of V20 owners on here. Use the search function at the top to search for information regarding different projects.

Welcome to your 2nd home! I see you are already providing valuable input!

Re: s.s.prop size
 

but if i tach out at 5800 prms with a 13 1/4 x 19 inch pitch on my s.s. prop wouldnt a 15x17 inch make it tach out at a higher prm>

Re: s.s.prop size
 

Step, next question is, "what does mfg state max rpm to be?
"...if 5800, then you got the right prop...if 6000, then you can stand a lil' less PITCH... :)...

I have a 150 hp v-6 mercury and I run a 14 1/2 x 17" pitch SS four blade prop. I turn 5500 rpm at 43 mph (GPS). My three blade prop is about the same, however just a tad faster top end. With the four blade you come out of the hole right now.
