[quote=samc99us]You can try letting them soak in PB blaster for a day or two. Disasembly is really going to depend on the level of prep the boat had originally; my bolts are coated in Tefgel which limits corrosion built up on the threads themselves, but many (most) boats didn't have this done originally.
Best bet is to use an impact wrench coupled with direct heat on the bolts themselves if you have an issue. Work the bolt back and forth to get it completely free. Worst case you'll damage the threads in the hulls and require helicoils.
Then there is getting the beams out of the hull sockets, I've found lifting the opposite hull generally releases the beams relatively gently.[/quote]
