I don't know. I bought the boat last fall from an estate so there wasn't much information about any part of this boat. My visual inspection tells me that it hasn't. There are no signs of weld build up or other obvious work. The main pin fits tightly in the main body and the blades are tight to the pin. We ran the boat 95 miles downriver last fall and the prop performed just fine until we needed to back down against the river current inside a marina. I have more images I can send and can do Hi-res macro imagery if you tell me what you want to see.
