Self Bailing - 20'

[JCB]

I am new to the site, and am an owner of a 20C. This is the first year it will be kept in the water. I have been reading, researching, and experimenting to find the best solution regarding the self bailing/below water line scupper. The past few days at the dock, water drains easily, but slowly off the deck. The through hull is an Attwood Stainless with a rubber flapper valve. I put an inline check valve in the 1 1/2" hose as well. Since the through hull is below the waterline (not advised from the manufacturer) water will remain in the deck drain lines until the boat is moving. I came across the Perko Bronze Cockpit Scupper which utilizes a rubber ball in its housing to to prevent backwash. Currently, at deck level, there is a plastic drain with no backwash preventer. Has anyone tried one of these perkos? Is there any other method to deal with the wet deck? I love the boat and the ride, but the scupper issue is pretty annoying. The boat is relatively new (2001) with a new 150 two stroke yamaha. Any tips or advice would be great! Thanks! jcb

Are your scuppers under water when at rest out of thebboat also? Mike are just above the water at rest but with my fatazz in the back water will come in
My tubes go straight ou the back i can install plugs in the holes if needed.

Im thinking of installeng ping pong ball covers

At rest at the dock, full of fuel, my scupper is about 6 inches underwater. Water is not coming in, but the water that remains in the drain tubes comes back onto the deck when I walk around the stern of the boat. That water won't drain until the boat starts moving. I am thinking the perko cockpit scuppers installed in the deck will hopefully stop the water that is remaining from coming back up to deck level.

So the perko cockpit scuppers with the rubber ball seem to be working really well. The two are connected beneath the hull, and go to an attwood stainless through hull. Rain/wash water exits the deck in seconds at the dock, and when walking around the stern water does not come back up on deck.

If possible maybe not keep it full of fuel, adds alot of weight and I notice a big difference
