HC: A few notes from what I have read. A 13x8 or 13x9 three blade are among those suggested for the 2 to 1. A 13x10 or 13x12 two blade also for 2 to 1. By taking 2 " of pitch out of your existing 13x11.5 three blade prop you would be close and should bump your rpm up about 400.
If I remimber correctly when we talked back in NC you said your A-4 was "tired". If you are a little low on compression I think that could explain some of the low but steady vac #s. Dan S/V Marian Claire
