Stainless has a weakness in saltwater for pit corrosion, where the ions setup a cell and eat away if there is a lack of O2 to form the protective oxide layer.
If you are going to the trouble and suspect any possibility, seperate, inspect and rebed the hull-keel joint. I used dry film lube on the studs to prevent gauling during the torquing. Lubing the threads also changes the clamp load to torque by modifing the rotational friction.
