Re: Propeller 172 I 150 hp engine (Lycoming)

Here are the propeller specifications for the 172I from the Type Certificate Data Sheet.

Note that propeller number 2 and propeller number 4 are for seaplanes. The pitch on all three landplane propellers is 53 inches, and the easiest way to verify the pitch is to have a qualified propeller shop measure it for you.
