Hi David, i’ll chime in and hope it helps. If you are lucky, the vane was torn to tiny particles and pushed all the way through the cooling system and you are free as rain!
If you are like me, it is lurking somewhere in the system between the pump and the exhaust outlet and pretty much the same size as when it left. In a raw water cooled application, that means it could be anywhere in the cooling system of your engine block, potentially blocking or contributing to future blockage. In a fresh water cooling system I think the chunks end up in the heat exchanger or where the raw water is introduced to the exhaust gases. Just as a suggestion, try not to run the engine, and starting at the pump, work your way up line carefully checking for pieces in the hoses hoping that it lodged in that line prior to entering the block. Hang on to any chunks you find so you can get an idea of how pulverized it is. After that point i doubt that there is much chance you would find it. i don’t know that there is much you can do after that except watch temps and signs of overheating. Maybe the new fully functioning impeller will push it out over time. I like to “lay hands” on my diesel occasionally! I had a hot tub that would heal itself on occasion after a brief group hug!
