I'm looking at couple of used 3-bladed props for my IO-540 Skybolt (IO-540-C4B5), both MT props (one an MTV-9-B / 203-52, the other “MTV-9-B-C / C20011B”). An Application Guide I found at precisionpropellerservice.com recommends MTV-9-B-C/C203-20d for the Skybolt. From what I’ve read, “200” and “203” in each of these refers to blade diameter in centimeters, with 11B and -52 referring to blade design, and they use SAE 2 standard for the hub/bolts, which seems to be compatible with the IO-540. Would anyone know whether these props would be compatible with a Skybolt equipped with the IO-540-C4B5?
