Is this prop junk or is it salvageable?

So, this is an Acme 1442 that was on my 91 Ski. Last weekend we were out taking a ride around the lake and hit something on the bottom while idling. After circling around and looking, it appears there was a pier footing or something on the bottom that was a round metal foot with about 8 or 10 inches of tube sticking out of it. We weren't in close to shore but this was a shallower spot of the lake.

As you can see, it sliced off a portion of one blade. The other two blades were untouched. I hear you can add material back to a blade, but do you think this one is able to be saved? I already have a new 1442 on the boat now, but I would like to have a spare in the garage.

Thanks!

Thanks for the reply, Jim.
