Here is where the bow kill tank will drain to. Unfortunately, it was going to be too complicated to drain into the bilge (located above the pipes outlet) as the fuel tank was in the way and the only other possible way to do so was to cut into a stringer (which i didn't want to do.). Here the water drains practically to the bung and most smelly water should escape pretty easily. A good blast with the pressure washer through the bung should see the smelly water escape.
