I plan on having an external filter so I don't have to pull the lid off 5x's a day.
Why change it? The JUNK that goes around the RIM of the tank is all messed up. Falling off, torn, etc. If the gasket was on the tank, like the NEW
hydramaster waste tanks are made, then I would not have to worry. Their new gaskets are dovetailed at the joints so they don't pull apart....fancy!
I'll go to a boat shop see if they have something for livewell lid gasket material.
