I have a 3 blade bronze propeller with markings of Michigan SX 16502, _mc 26 8" x ? pitch. I couldn’t find anything in my Michigan props fr0m
1944 to 60. Any info would be appreciated. Thanks in advance
Those numbers appear to be a re-work service number. Many of the service stations use their own code, usually all numbers when they repair a prop. A lot of the early OMC props have the part number and diameter and pitch cast at the inner hub. You have to scrape the crap away to see it with a good eye and flash light.
