48-73136a Prop - Merc 650 1974 65HP

[iboatWayne]

How can I decode this prop number? I'm not sure this is the correct prop for my motor. It was actually on BACKWARDS when I bought the boat!
48-73136A 4 13P is the part number. What's the correct oem part number for the 1974 3cyl 650's? If it helps, my ser# is 4046610. I don't see this part listed on eastcostmarine.
