I am trying to find out the pitch of my prop. I have a 92 90HP force on 24ft pontoon boat

On the inside ring "P692" is stamped

ON the outside I have "M1961" "C.M.M" and think "15"

Can anyone tell me if any of these tell me the pitch?

Also, i measure the depth from the start of the blade to the end of the blade and it seems to be about 5". This would be if you are looking at the prop from the side.
