Cockpit drain covers

I'm doing this right now. I went with the TH-Marine drains with the grate. New hoses and clamps. All new hoses for live well and wash down. The drain on the live well crumbled! Glad I checked! Drains below the water line.
 
nice job Dennis on that liner removal. when in that deep do everything you can/that is needed....
 
Over the winter in my old 20 ft boat I would cover the boat and put boat brushes on top of the drains. Brushes kept any leaves from blocking the drains.
