Hey 42/44 friends, might consider drilling a hole aft of the catwalk, just forward of the petcocks in the stern. I had this misterous fresh water always showing up at far aft after a run. Turns out after I opened this up, I sucked out about 10 to 15 gallons. I am in saltwater and this was fresh. Not from my water system, but rather rain water finding the lowest point to travel. Found my boat waterline moved up about 1/8 in. I found these caps to plug the hole, but easy to pop off with a flat screw driver. Good news I found my last rain water leak. Bone dry now.
