Question for the propeller guys: just installing new top prop for M20E, the IO360 has the "K" type engine flange, and the prop supplied is "R" type; the manual and the Hartzell tech assure me that "R" can be installed on "K" flange in either mating position (180 deg) (and that in fact Hartzell does not even produce a "K" prop flange since the 1960's). I'm just looking for reassurance from some of you knowledgeable MS'ers that there is no known issue with having the one additional counterbored hole on the prop hub mated to a non-"drive-bushing" site on the engine flange.
the old prop was HC-C2YK-1BF
the new prop is HC-C2YR-1BFP
thanks
