Hey can you take out the waste tank and what material is it made of? Mine appears to be leaking into the bilge even tho I have never used it and thought it was flushed out when I bought the boat!

Probably not the tank but the hose to it. The waste hose will start to breakdown over time

I'll check that out its not leaking toward the cabin but running out of the gunwale drain!

Vent tube is clogged

This just happened to my water tank on opposite side. They used all plastic adapters all the way through back in the day. Replaced them and all works fine. You should be able to access it through the under bolster storage.

Thanks guys, its leaking around the hose to the tank...
