prop / thrust washer question

are thrust washers generalized at all? Or specific to each prop?

I am in the market for a new prop for my rig. I am currently running a 13.25x19 aluminum prop. I see used props from time to time on ebay and other places and it just comes with the prop. They have hubs, but just wondering if my other prop hardware will work with another prop.

And if not, how do I find out what I need to get?

thanks

Mercury thrust washer is pretty much all the same, top can be different with the nut lock made on it or a washer that fits over the splines on the bottom and has the nut lock on the top side. Other brands have several variables. What motor?

1993 Johnson 90hp

I have an aluminum 13.25 x 19p right now.

Don’t know if my hardware will work for any additional props.
