There are places on these boats/trailers where a 1/2" SS locknut has to be used, such as engine mounting, the spring bolts and axle U-bolts. If so, put some grease inside the nut before installing it, and the galling possiblity should be eliminated. I learned that from my Mercury engine installer and it seems to have eliminated the problem. But on trailers I still use the conventional nuts & lock wahsers in all the other places.
