I didnt see another response, so thought i would offer an opinion.
i could be wrong its happened before, however others i have known with salt water damage, it never ends very well,
Salt water corrodes things quite badly, so im not sure a long term repair is something that would work for a long period of time.
This is just my opinion thou, also based on the experience of others.
