Hi, hoping some one could help me locate an impeller for a 1960 Chris Craft wood boat with 283 V8 Chevy engine. The pump itself is a sherwood, and has M10160G, stamped on it. The closest I have been able to find is some that are made by ITT Jabsco, but none of the numbers match up correctly. I have added a few photos. If any one can tell me where to locate one of these, or what the correct cross ref numbers are, that would be greatly appreciated. Thanks
