I'm pretty sure this is not true. At least not on less than glacial time scales. Likely, any issue with water will be one of wicking from a penetration, and not osmosis. Could you point to a reference regarding this? If osmosis and crevice corrosion is a concern with marine wire, tinned wire won't prevent it.
