Yes it’s a 70 inch prop with a 52 inch pitch. Pretty much a cruise prop, I believe.

Hi All,
I am working on purchase of a really nice 415E down in South Carolina. As stated above, has the C-85-12F engine. Last entry in prop log shows prop to be a McCauley 1B90CM7052. It's handwritten in there. I cannot find any references to this prop. Is that a misnomer? Is it supposed to be (last four digits) 7152? That is a cruise prop, correct? Thanks for any help with clarifying!
