Re: Prop dia ? 4 alpha 1

I have an Alpha 1 Gen II that came with a 14X23 prop and no trim tab on the zinc over the prop. I have a 14.25X23 that I am going to put on with plenty of room. Most everything I have been told about prop sizes is that diameter does not affect that much where pitch does change rpm approx 200 rpm per inch. It should work, if there is a trim tab on the zinc just get a zinc without a tab.
