Have any of you had experience with these automatic draining plugs. I understand that they have a type of check valve which only lets water out. I was thinking this would be good on a Montauk in the motor well area.

I have one in a '67 13'(about 10 years) and it works great! Its especially handy when I leave it in sea water overnight & in the rain. It lets the rain out (mostly) without letting salt water in. OkieWahler

Hello,
I think these are widely respected:

Good luck.

Chap,
The scuppers you mentioned...are they for the back of the transom? I was referring to the plugs that go on the inside of the boat.

Yes the Rabuds go outside on the back of the transom. I am unfamiliar with a plug that will drain, but would like to know about them as well. My Shamrock had the rubber "quackers" pushed thru the brass tubes, which were similar to Whaler's, and they were basically one way until they rotted out or fell out.
Thanks

Take a look at the "Tempo Automatic Drain Plug," #TEM999PDP, on page 583 at boatfix.com for a view of the "quacker." Mine worked quite well, but they were above the water line. I don't see that they would be water tight if submerged in a spashwell. There is also a flaring tool there on that page.

Chap,
Did that Quacker style plug allow the boat to drain while at rest? How much flow pressure does it take to get the water running out the tubes?

thanks

The "bill" of the "quacker" stuck out the stern of the boat. How'd that sound:).
This bill is very thin rubber, thinner than inner tube, maybe, with the tube also very flexible. In reverse I assume it would collapse and not allow water to enter the boat. At rest this bill would be above the water and would allow easy drainage with the Rock's slight bow up static trim. Inside the boat the entrance hole sat in a slight depression at the stern's deck. The water would drain almost as fast as the diameter of the drain would allow and would not require any pressure. They did make the diameter of the tube smaller. Installation would be limited by the length of the tube, possibly modifiable.
Hope that helps.

I forgot to add that I would spray silicone into the tubes from the inside to prevent the "lips" of the "quacker's bill" from sticking together, would also help flow, I thought. They are not super fancy or high end by any means.

That is very helpful. thanks.
I currently have dryed out rubbet flaps, and am torn between new flaps or the more expensive and fancy shmansy ping pong ball version. These quackers look like a nice compromise.
have you had any experience with the "ball in a cone style?

A friend has the ball style and they work. Rabud is apparently one of the better ones. I don't particularly like their fragile nature even if the are Lexan etc. or the idea of putting more screw holes in my sponge. They stick out also = bustoffable. When the quackers went bad in the Rock, I just plugged the holes. Took the plugs out when I had to drain.
Thanks
Chap
