plug lining
 

I need to replace the lining to both stern plugs in the transom. Does anyone know how to do this and where to get the replacement lining?

Thanks,

Re: plug lining
 

You need to get the brass drain tube and flanging tool, here is one source or do a Google search for "drain tube". West Marine sells the tube but not the tool.

Re: plug lining
 

hey I just ordered one.When you install should you bond with west system resin or something and is there any special trick to removal of the old brass. Thanks Keith

Re: plug lining
 

Is only a thin brass sleeve so you can punch thru with a small chisel or screwdriver. I seal with 3M 5200. Dry fit the new sleeve and cut leaving enough length to flange over with the compression tool.
:D

Re: plug lining
 

Thanks for that info.I just picked up a 1973 23 CC in jupiter this weekend that has been sitting for 3 years and the brass sleeves are very worn. I ordered the tool and I will pick up the 1" tube from west as you said and get it done. Keith in Boca soon to be Hobe sound Fla.

Re: plug lining
 

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

Re: plug lining
 

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

Re: plug lining
 

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

Re: plug lining
 

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

Re: plug lining
 

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.

Re: plug lining
 

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.

Re: plug lining
 

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

Re: plug lining
 

I replaced the origional brass tubes with
long ones bought from a whaler dealer, cut
them to lenth, used a flairing tool with
5200. Its been 12 years without a problem.

Re: plug lining
 

Here is a plastic type drain tube. No flanging tool required.

I would use the brass that will probably last for over a decade,
But the shop next door does metal machining so I am having them made from a block of Titanium with a flange for 1/2" mounting bolts! (Not)
:D

Re: plug lining
 

If you're pulling the rotten tubes out of the floor-definitely check the surrounding wood-you might not like what you find. Mine was pretty easy to dry out and then I got the rotten wood out with a few different router bits and speedbores-sealed everything up with CPES and then made a plug with thickened epoxy and drilled it out again. Kind of involved but I feel a little better about that part of the boat that is sitting in the water now. I'm not even sure if I'm going to put a tube back in but I might just for aesthetics.
Anyone who bought the Whaler tubing-is it thicker than the standard brass drain tubing that they sell at most marine stores?

puck yuck give me a call at offshore systems custom fiberglass at 508 759 1177 i have the tool to install brass tubes / on my customers i install fiberglass tubes

Re: plug lining
 

I asked my local boatyard to check out my transom/bilge drain plug and they popped out the old plastic drain and attached a brass fitting to the outside of the transom. The fitting recieves a 3/4 brass threaded plug. If I put my finger in the hole I can feel the plywood in the transom which doesn't seem too right. What should I do to make this hole/fitting/plug etc. be right?

Re: plug lining
 

HatTrick-
There seem to be many possible corrections to that boat yard fix. I don't have the building skills as the other craftsmen on this site, but if it were me, I'd pull that plug holder back out and make sure you get the wood nice and dry and then seal it with a penetrating epoxy and/or epoxy before putting that holder back in. The thing I would worry most about is if they just screwed that in in that area, sooner or later you're going to have a fine amount of water intrusion if you don't seal it up properly. I'd hate the thought of that plug holder not being fastened securely.

Re: plug lining
 

Just FYI for you guys.. I have a 77 23' with the plugs that run through the floor. They appear to have been replaced a long time ago with plastic ones and one on the starboard side is cracked. lengthwise crack running the length of the pipe. After splashing it the first time it didn't seem right to have that muchwater in the bilge... Hmmmmmm... just a word to the wise to make sure those are right on. I have to fix it but in the meantime I would keep it plugged from the underside which kept it from being self bailing anymore but will keep water from coming inside. a bit worrried what I might find now if that allowed water into the wood blocks. I'll soon find out.

Re: plug lining
 

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.

Re: plug lining
 

When I installed it in my transom, I set it in slightly from the outside edge.
This made a sort'a recess that the backside of a standard Garboard plug fitting would sit in.[1in PVC]

I have seen where some transom core's were installed with a larger section [5inX5in radius] around the drain removed. It's just heavy solid glass there.

Re: plug lining
 

Has anyone done anything besides replacing the brass tube in the forward fish box on the 23 sf. I just found a crack in the old one-the tube actually looks more like copper or bronze than brass,but I don't know. Anyway,besides plugging the hole, what fixes have you done to this drain. I'm liking the drilled out thickened epoxy route for the back ones, but the fish box drain seems like it might have a different set of issues with the gap between hull and liner. I haven't pulled it yet and wasthinking of glazing it over with some epoxy,but that doesn't seem like the sound fix. Suggestions?

Re: plug lining
 

Hermco is that tool long enough to work on the floor scuppers. The original drain tubes do not appear to be flared on top, only on the bottom. Should I install the new brass tubes, pushed up from the bottom with 5200 as a sealant and have them flush with the top, without a top flare? Or do I need to flare both ends. It would seam better to flare both, but is the tool long enough?

Re: plug lining
 

You can use a longer/shorter 1/2" bolt if you need to. When you see the tool you'll understand. :D

Re: 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!

Re: plug lining
 

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

Re: plug lining
 

Yep 1" I'm in the process of replacing all my drains, bilge, scuppers and fishbox. I figured the originals from 1974 could use a break before they took a break!

Re: plug lining
 

How long were the replacements? I have the option of 1 7/8" and 2 7/8".

Thanks,

Re: plug lining
 

I'm not sure! I believe you will need the 2 7/8", but don't hold me to it. I got two 3" and to longer. I believe the three might work for the bilge, but I might need to cut it a hair before I flare it. The longer ones I got for the scuppers. The brass looks real nice when you put it in. Too bad they don't stay shiny very long. I still like the idea of metal vs. plastic though.

Re: plug lining
 

Hermco, thanks, I ordered the flaring tool, received it today and replaced my fishbox drain pipe with it. I used the 1" brass tube and lathered it with 5200 and flared away. It looks as good as new! I was surprised how easy it was and how nice it came out. I would definately recommend the brass tubes vs. plastic, they seem much stronger and look sweet.

Re: plug lining
 

Glad it worked out for you. :D

Re: plug lining
 

What's the best way to get the old ones out?

Thanks

Re: plug lining
 

Puckyuck - I took a deep well socket (I think 3/4 inch) it was the exact outside diameter of the brass tube.

Carefully grind the flare off the old tube on the side that is easiest to access - then tap the old one out with the deep well socket.
It worked for me

Re: plug lining
 

I used a flat head screwdriver and hammer and gently pryed the old flared end straight then tapped out the tube with the screwdriver and hammer. When it was halfway out I just pulled them out with plyers. The old flares were pretty worn and easy to pry and straighten. Good luck.

Re: plug lining
 

I did four this weekend.

Try cutting them lengthwise with a fine hacksaw blade, just through the brass body and flare, carefull not to cut the fiberglass. Then pry towards the center, kind of rolling the tube in. The tubes can them be tapped out through one side or the other.

Re: plug lining
 

were did you get the 1" brass tubes longer than 3"?

Re: plug lining
 

I bought 6" long 1" O.D tubes from a local marine/outboard dealer but I believe there is a direct application for long tubes in some Boston Whaler model.

I bought the flaring tool online. The manufactureer is Moeller, got that info from this string,

I have not installled the new ones yet. Letting things dry out and contemplating the penetrating epoxy vs West System treatment. But, I have flared a tube and they are soft and seem to flare easily and not alot of excess tube is necessary.

Re: plug lining
 

How much do you have to leave to flare?

Re: plug lining
 

don't know exactly. I bought a few extra, short tubes, to practice but I'm pretty sure it's not much more than 1/8".

You have the flare tool? the tubes are cheap, dry run a few.
