Mine all have solenoid valves on them. Hit the switch and they drain. I'll be in the boat this weekend, I'll try to remember to get a pic with a part number.

Any info or pics of your setup would be great. That's the way I'm going to go.

I have them on my boat and they have worked flawlessly for many years. When the engines are running there is enough pressure that the water doesn't go down the drains but as soon as you shut down, it just trickles all the trapped water right out so there is a huge reduction in the chance of reversion or leaks into the motors.
You can see them just above the waterline by the tabs.

Sorry guys, I didn't get pics this weekend like I hoped. I never made it to the boat. I haven't forgot about it, but I'm traveling for business the next 7 days. I will be winterizing when I get back, and will get all the info posted when I get back.

Ok thanks. Try to get a part # or manufacturer. Lots of solenoid valves available online, but tough to telll how well they'd fit without putting hands on them.

I know its an old thread but I am in process of figuring out how I want to set up a drain system for my cmi headers. I have made some fittings with a 3/16" hole to fit where the blue drain plugs are, rather than putting a fitting through the transom, how about draining into one of the unused the sea strainer ports? When boat is under way additional water could go up through the fitting rather than loose water through the open line at transom? When the motors are off and no pressure in the strainer the headers would drain into the strainer? Thoughts????
