plug lining

Ok, I get it, I thought it looked like a regular bolt. I was even thinking I could make a tool to compress it. I easily removed the scupper drain tubes they were not cracked, and seemed fairly solid but needed to be replaced as the top flange was gone and they appear to be original. I picked up new 1" brass tubes at Nauset Marine and they slid in perfectly. I am now thinking I will also replace the bilge drain and the fish box drain while I'm at it. Make sure everything is water tight!

Is 1" the size tubes needed to replace transom drains?

[stevebrownell]

I have to respectfully disagree with the conventional wisdom on the use of those thin brass tubes for scupper drains. I've seen a bunch that are rotted out, including those on my boat. Brass just isn't a good material for constant contact with salt water.

I forgot who posted an alternate option on this board when they were doing their boat (Strick? Trayder) but 1" plastic tubing, epoxied into a reinforced hole in the transom seems like a far better alternative. Nothing to swage, no tool to make or buy, and they are stronger and corrosion proof.

Just my $.02

I agree.I wonder if any one makes them in stainless with like a bolt on system from the inside.Keith

What type of plastic tube? Where could you get it? Would you have to drill out the original holes?

I used Gray [EMT] PVC on mine. Sanded up the OD real good and installed it in a coat of epoxy/Cabisol.

Did you guys use the same thing for the thru hull scuppers in the floor? I am thinking I should replace them, but am not sure how to go about it.

I drilled my through the floor scuppers out oversized, plugged the holes with west system and then redrilled to the size of the brass tubes, used 5200 and installed the tubes. That way the expandable plugs fit good and there is no space between the hull and hull liner for water to enter.

I've heard that brass tube drains will last ten years or more and should be replaced as part of regular maintenance when they begin to breakdown. Don't plastic thru hulls and tubes crack after a few years?- PF

Warthog,

Thanks for jarring my thick skull - the fix idea came from your excellent rebuild photos. Grey pvc is what I used also. Cabosiled and faired.
