Keeping water from comming up the drains

These are more durable than they look but do require a bit of maintenance because debris such as sticks and leaves will prevent them from working properly. The maintenance is easy, grip the clear housing on the outside firmly and turn the housing 1/8 turn to remove clean and inspect.
Chances are the boat has some scuppers there already but they aren't working properly.

Thank you RidgeRunner. I considered them but have just one concern. When the side of my boat rubs against the pier, they would break. Those clear scuppers are made of plastic.

You can do this, cut a round piece of about 1/16" thick rubber round a little bigger than the opening on the hull drain fitting and screw one screw on top of the circle on the deck fitting to create a "gate" kinda thingie, or you can buy that thruhull fitting in stainless only, but big $$$$$, Grady is using them.

I read the post wrong and assummed the floor drains went out the back. I could not agree more. Plastic is not for the sides. I even questioned the quality for the transom but they worked great on my boat for 4 years before I sold it. It drained thru the transom.

Ah, the age old question.........

Willy's method is the only one that works so far.

But one day I'm going to figure it out.

Didn't Hammer put some one way CK vales in the line under the deck??

I remember that, he did. I don't remember if they were for marine applications or another application.

Hammer did, and I did too, they didn't work out too well, mainly because the bottom of the floor drains is at or just below the drains out the sides, and water, just like poop, will not flow uphill.
