The others covered the spun hub thing well – note you cannot see the thin rubber interface.
Now for your pitch question:
Before you go to the trouble of measuring the pitch, look at the prop carefully and you will likely find the diameter and pitch numbers if it is an OEM prop. Look at the aluminum casting on the end of the prop around the edge of the brass hub. You may see numbers in this format: "10 1/2 x 13" which is the diameter and pitch. I’ve also seen these numbers stamped into one of the blades up near the hub. Yo may have to carefully clean some dirt or corrosion off to read it. You may also find the propeller part number, and can look up the pitch. I have a dozen or so props that fit your motor and nearly all of them have the numbers on them.
