Can some one tell what the stock prop is for a 2007 20ft cobalt?
Tring to figure out if i have the correct one.

It's going to depend on your engine and outdrive, among other things. It looks like Cobalt made a 212 and a 222 that year as well - which do you have?

Cobalt usually published propeller charts for boats of that vintage - see p. 1-15 of this, for example: https://cobaltboats.com/art/manuals/2007_212_OM.pdf

So glad you found us mmh.

A major variable is engine size and outdrive type.

Any pics?

And welcome aboard mate.
