Loose Drain hole

[salmonee]

I need a band-aid fix to get me through the next couple of weeks for my loose drain hole. You can see the photos at the following thread. There was a thread I responded to (which I can find now) saying that I can get 3M 5200 or better at the Home Depot store but for $7. Now I suspect the poster was implying that I can get something just as good or equivalent in adhesive/epoxy form? Anyhow, I believe my drain hole is made out of nylon or similar material. The bonding must be water proof obviously. Any recommendations??

I'd go to the local marine store and try to get a brass garboard drain as posted. I also suspect you will have to get rid of that plastic tube and clean that area good. Someone has already applied a band aid. I would use "marine tex" on the area, let it dry, grind it smooth, and mark the new drain. I'd then drill the holes for the drain larger than they need to be and fill them with marine tex, then after it dries go back and drill them smaller for the screws for the drain.

5200 would probably work, but I think you might need marine tex to hold the screws in the transom.

I had to do something similar in the last boat. it took several days with weeping in the drain once I removed the old tube. Some kind of wadding such as a t-shirt rag might help with drying if you get weeping when you remove the old drain.

Re: Adhesives, caulk, epoxy, 5200

home depots near me have 5200....in the paint supplies area near the other gorilla glues, etc.

if that first bandaid isn't doing the job, you probably won't have much luck putting another over it. in the end you'll just have more crap to clean up before putting a good fix on it.

drewpster and kurt have given good advice. marine tex cures pretty quick, prep'ing the area will take the longest depending on how much moisture you find in the transom.

sal you need a brass fitting sold here on iboats. i just re-bed'd mine with 4200
it is held in with 3 ss screws and nuts on the inside.
mine is in a pocket that tapers out to fiberglass as doesn't mount or touch the wood

Kurt,

I have some questions. After removing the nylon drain hole, are you saying that I should apply marine tex and plug up the entire hole where the drain used to be? Then go back and drill a complete new hole for the brass drain once the marine tex cures? I'm a little confused here. I'm not sure if the new drain hole diameter would fit right in with the existing drain hole diameter. I took some measurement last night and the drain plug diameter is ~0.7" ID but the drain hole diameter is about 1.3" OD at the face. Not sure how else the drain hole is shaped inside the transom.

I believe I understand the marine tex for the drain hole screws. I believe this is to add strength to hold the drain hole as my transom is likely wet.

I agree totally!! Install a garboard and be done with it, no more worries and on to the next project, they are not expensive and with the 4200 or 5200 you will still be in good shape and good to go. This is what iwould do, just my 2cents. Get a garboard plug and be done with it

sal; was going to ask if there is a reason the brass fitting wouldn't work for you?
it seems like it would eliminate the problems with size you are having and would be a permanent fix.

above is a pic from the out side. as you see the flange covers up quite a bit of hole. i dont think you would have to do any thing other than clean area well and drill the three holes to hold it on

Re: Adhesives, caulk, epoxy, 5200

The problem I had was that the transom was solid, but the plug area was so messed up from the PO torqueing the plug in an out that the screw holes were stripped.

I didn't totally fill the drain hole with marine tex, but I did have to do quite a bit of bedding and I did have to re-fill the existing holes and grind/sand everything smooth again before installing the new garboard.

I also had to bed and predrill holes for the screws as the fiberglass was eaten up around the holes from the PO torquing the plug.

Not only that, but I found the inside of the transom hole was uncoated. I decided to coat the hole the hole with resin and bed a solid drain tube. It was a messy job, but the transom was sealed good to any moisture.

I did have water weeping for a few days because I had just dunked the boat before I noticed the problem with the plug. The weeping lengthened the time to make sure it was dry to do the repairs to get back in the water.

Re: Adhesives, caulk, epoxy, 5200

My only reservation to installing the gardboard is that I had planned on taking the boat out this weekend for some salmon fishing. This weekend should be really good. I didn't want to mess with the thing until after salmon season. I will eventually install the gardboard. It also sounds like it could take me a couple of days/weeks to complete. A couple of hours here and a weekend there.

Any idea on how my drain hole is held in place? I don't see any screws. I wonder if the 5200 is the only thing holding it in place?

What can you get to from the inside?

Might pick up one of those 'snap handle plugs' to plug the hole from the inside as insurance for a band aid fix while you're fishing.

And please tell us your bilge pump works!

Re: Adhesives, caulk, epoxy, 5200

the bilge crossed my mind too!

That's what I like about my current boat only 15' but with 60 cubic feet of foam flotation. I, uh, forgot the plug and the deck was barely slippery. Deck/drain was at/above the water line.

Re: Adhesives, caulk, epoxy, 5200

My pump works. I use it on every outing just to make sure I don't take on too much water.

I scraped away some of the 5200/4200 material last night. I don't see how this thing is held in place except by the 5200/4200 between the drain hole and transom. Anyhow, I'm applied some 4200 at the rim of the drain hole to prevent as much water from entering the transom as possible for this weekend's fishing. I'll do the fix after fishing season.
