RE: YS 170 prop - 4 blade?
I don't know why the APC would not be recommended as that is all I have run on all my YS engines for quite some time unless I was testing a new prop. If you are currently running 3 blades, and this is from memory since I haven't had a 3 or 4 blade prop for a LONG time, tha going from 3 to 4 blades is again dropping an inch in either diameter or pitch from the 3 blade

APC says their 15x12 - 4 is designed for the 140 and should not be used on the 170 or 175. I'm going to use one of my 170's in a scale application is why I am researching where to go. Ordered some 15 and 16 blades for my Zinger hub in various pitch to see where it's optimum. Thank you for your input.
