Ed,

 

I=20 checked today, and mine has an 8.25 (quickly measured, not accurately) = cord.  Time will tell about what RPM I get and if I will have to = trim the=20 prop.  I=92m reminded of the line from the movie =93Guys and = Dolls=94.  I=20 don=92t think I want to take the bet and end up with an ear full of=20 cider.

 

I=20 got the new radiator today, so bracket construction and installation = can=20 begin.
