I had the same experience with a loosely installed bulkhead between the lazarette and the cockpit. On one particularly breezy day I ended up with a bilge full of water from the outboard well drain finding it's way around&over the bulkhead and into the bilge. water was above the cabin sole before we noticed the problem.
folks who still have outboard wells might want to make sure the bulkhead is sealed right up to the deck. a small gap at deck level was the path from my outboard locker to the bilge....
cheers,
Bill
