Loaf,I have a 54" prop that was made by Bert Larkin for a direct drive Turbo EA81. I have since fitted a reduction drive so no longer require it.

Loaf,If you run a redrive, which you should, my prop will be no good as it will be too small. It was made for a direct drive. I have fitted a redrive to my turboed motor and am running a 68" 3 blade warp drive pitched to achieve 5800 RPM @ 6 PSI boost. A 70" prop would be better but I bought the redrive and prop together 2nd hand so it will do for now.A 64" 2 blade timber prop on a EA81 with a turbo would be way to small.Rob
