I know that they changed the head at some point, but I doubt that they changed the head enclosure mold. So, I assume that the 2006 and 2005 head enclosures are the same.
The head in Journey On is bolted to the floor. The floor is a separate molding, raised above the hull a couple of inches, and you can peek underneath by looking through the bilge pump compartment and see what's going on. If that doesn't satisfy you, pull a bolt out. It's not glued in the hull but the head pan. You can also look where the outen going hose passes through the floor.
