On my boat, there were cockpit drains in the back corners just outside the battery box and livewell on the other side. You might want to check the hose from the floor drains to the thru-hull if you have that setup (rod boxes were removed to gain access to the drains).

I replaced the plastic drain fitting and all plastic thru hulls with stainless steel fittings from Gemlux. I also replaced the hoses for peace of mind out on the water. I used 3M 5200 to seal the thru-hull fittings.

The plastic thru hulls and fittings break down with exposure to the sun.

Thanks for your response!! Yes indeed was the hose and the drain scupper that were leaking. Same setup as yours.

Wellcraft builders put the scupper drain in a direction that the rubber hose was collapsed due to the stress of the forced position. I removed the scupper, redrilled new pilot holes for the screws in a location that the new hose won't colapse and used a Shields PCV hose.

To this day the leak has been reduced, still getting some dripping I think it's coming from the wet foam over the fiberglass. Excess water in the foam ends there.
