Laser 2 props

[Ccfbailey]

Looking for some info on a prop. I've come across a Quicksilver Laser 2 ss 20p used for a good deal. Part number ends in A40. I see that the newer props in that size end in A46. Specifically the Mercury Laser 2 sport series. I'm wondering if there is any difference in these props. The part numbers are the same except the last 3 digits. This used one is a quarter the price of a new one and hoping it's the same design as the new ones.
