broken prop. need help with specs.

72 merc 1150. I hit a rock and broke the prop. Need a new one. So confused with pitch and such. Any help? Also what's hubs an such?

There should be numbers on the outside of the hub next to where the prop shaft pokes through. Hopefully you did not bend that , although I suspect you have a aluminum prop which takes the brunt of the force vs a SS prop.
