Hello Scott and welcome! What is wrong with your lower unit? You probably know that you must pull the power head to service that lower unit. Plenty of parts are available on ebay. Those gear cases were the same on Johnson/Evinrude/SeaKing/Brooklure and plenty more of the gale manufactured machines. Years 54 through 58 maybe more. They are not easy to rebuild. They have a tendency to leak water. If yours is leaking just change the grease once in a while. Make sure it’s empty before freeze up time.
