Replacement Prop needed

I guess my view of a 3 blade MT or any 3 blade of a 4 cylinder is kinda dim.

Don’t have any real world experience with that combination though.

3 blade prop and an IO-390 

of course the MT prop is not in the IO390 STC

I believe only the 2 blade metal Hartzell Top Prop was approved for the 390 STC initially. I don't know if there were plans to extend approvals to other props or not, or it there were/are field approvals with the 390 and an MT or other.

I wouldn't give up my MT to get the 390.

I have been pretty impressed with the MT props on 25 Diamond DA 40 NG aircraft. Highest time is almost 1200 hours (year old). About halfway to TBO. Taking the abuse of a flight school pretty well. No AD's to worry about. Good factory support. No rpm restrictions on the Mooney. If and when I need a prop for my M20F, I'd get one. Just plan ahead, very long lead times.
