Hope I put this in the right place. Does anyone have any tricks to remove nuts and bolts that are frozen from saltwater?

It really depends on how bad they are, size, how long they’ve been seized, and location. Heating the nut can help loosen the threads since both metals will expand at different rates. Brake fluid is a pretty good catalyst. Sometimes it’s just best to cut your losses and use a nut splitter, grinder, or sawzall to remove the offending fastener.

Yep as suggested as long the bolt's head doesn't break inside the crankcase...

heat

mix of acetone and ATF

prevention of seizing in the first place by coating the bolt threads with permatex #3

OK applying Permatex 3 to the removed salted bolt, what about all the others ?
