13 1/2"-14 1/4"-& 14 1/2" would be the DIAMETER of the props blades outside edge to outside edge. Not anything to do with shaft size. P is the angle of pitch the blade has. Usually 4 blade props are smaller diameter than 3 blade props. The differences are in prop shaft splines by brand of motor. Mercury, OMC (Johnson/Evinrude) ,Yamaha. That would be the prop "hub".
What you most likely lost & are looking for is a Renegade 4 blade 13 1/2" 25 P prop with OMC hub. I have one I'll take $175 cash for if you pick it up here. I have no use for it. It came off a Evinrude 200 Vindicator. Same lower unit as yours.
