Hello, folks!

A few props came alone with the boat I bought (sounds like a poem :). They look like no match to what I have, so I decide to sell them. The thing is, I have no idea how to describe them. Inside numbers (like 18-79576-21) doesn't mean anything to me and web search came with no results.

Any idea on what those numbers stands for and how to measure the props themselves?

Thank you very much to members who knows!

The last set of numbers is often the pitch ( so 21" pitch) The first bunch is usually meaningless product numbers.

Wow! That easy? So, If I'll measure diameter and it will be, lets say 15", I can AD this prop like 15x21... cool!
