Prop Identification?

[76SeaRay]

In the pile of parts with the restoration boat I bought, there is a prop with the part number 172490. It says 18 pitch. This is a 76 Sea Ray 22ft overnighter with hardtop (model SRV220 and 3600lbs) that I will be restoring and changing from an OMC to Mercruiser. Is this prop a Mercruiser or OMC and would it fit with a 5.7L Mercruiser for this boat?

Thanks...
