slightly off topic but if the drag washers are anything like those in a TLD you can get away with getting the washers wet by rinsing the washers in metho or acetone, which displaces the water and evaporates alot easier too. hairdryer to dry and you're away... done this several times to my TLD20 (a veteran that has seen a few dunkings and swampings) and the drag is still good.
i'm not saying dunk the spool and washers in water, just a way to fix the drag if your reel goes in. as for the internals, open up the reel ASAP, flush it with fresh water then flush the fresh water with INOW/WD40, then close it up and remove any excess from exterior with soapy rag.
