SX210 drains about 1 gallon of water from drain plug every time I take it out

Sorry for my (little) out of topic question... What is a "scupper", and where is this scupper valve? Thanks

Great question. A scupper is a an outlet on your boat with a flap that makes it one way. On your boat, I believe it will be above the Starboard Jet under the swim platform on the left side, which is where it is on mine. We have self bailing cockpits, so that drain/hole in the back of your cockpit goes into a white corrugated hose through your engine compartment out to the Scupper where it drains outside the boat. These are plastic from the factory and also reports of them leaking or breaking have been reported. The Stainless Steel one that is linked, the Attwood, is the replacement most of us use and is a fairly easy thing to do.

Here is a link to a picture of mine after replacement.

On 2010 and older SX/AR's It was a self bailing valve located low on the center transom between the impeller units. Bad design. They wouldnt seal all the way, and water would make its way into the lower hull. As the years went by it was re designed/relocated.

I know for a fact that my measures work because I wake-surf so much. All that ballast, the boat is low in the water for the entire day. I dont take on anything.

Thank you guys. I always assumed that the drain in the cockpit went directly into the bilge, for the bilge pump to take care of. I did not know that there is a hose with a dedicated outlet.
Thanks you always learn new things here.

Every time we go boating and I pull my 2006 SX210 out of the water it drains about a gallon of water from the drain plug. Any idea where to start to figure out why. And on that same note, should I have all of my internal drain plugs left open or should they always be closed? Obviously the main drain should be closed when boating but the "cooler" plug and the 3 inside the engine hatch I have been leaving them open with the thought that if there is any water it will allow it to flow to the rear of the boat so it can drain when I pull it out. Is this right?

Is there a way to make sure I don't have water trapped inside somewhere? I go boating on the river so my boat gets very sandy and Im just wondering what if there is a blockage of sand under the floor somewhere? Should I remove the large floor piece to check? I'm just not sure how the drain system works and I towed my boat home this week to clean it up and whatnot so Id like to give everything a good once-over while I'm at it.

Thanks for any and all help and advice!

Check the housing around your gardboard plug (drain plug) specifically make sure the screws and seals to the hull are good. I’ve seen where those screws were loose. This can be corrected with 5200 sealant and is an easy fix.

^ Second the sealant suggestion. Not all sealants are the same. Some are made to come off with little effort, some are made to be permanent. Use a permanent sealant.
