    It has been said that GL5-rated gear lubes will “attack yellow metals,” which there is often a lot of, in OMC lower units. Sometimes I have run into OMC units that have had very severe wear to these bushings/bearings and I wonder whether that had anything to do with it, or not.

    Long live American manufacturing!
