Joe, A similar thread occurred on the c27-talk: catalina27-talk: Bilge Overflow
You can read those postings to see if you think they may answer your question. Basically, while motoring at more than 5 knots some C-27's have experienced siphoning of water through the bilge. Hope this helps. I'm sure you will get info form others, too.
