    Well, the 1958 Sportwin has the small gearcase, which was prone to water leaks, then terminal wear.
    So, if it were me, I would use the best oil available to avoid damage. The latest OMC/BRP/Merc/Yamaha gearcase lubes have the ability to absorb some water without losing too much lubricity….Cheap insurance.
