Whats the floor made of Rick? Air it out it should be fine. Not much wood in any boats anymore, but still keep an eye out for any intruding white mold. If you see it, get rid of it right away, dont use bleach or ammonia though, as it only works temporarily.
Just airing it out should be fine, your battery should be fine though. I had my submerged for the season unknown to me, 2 years have gone by and its fine.
Hope it works out for ya!
