Hello there corenzio ..

I would 5200 fast cure on ever thing below the water line ( use Mineral spirits to clean up.. an empty box for trash and a roll of paper towels will do every thing you need ).

The reason that Nylon or other plastic fitting are not recommended for 'underwater applications' is for sheer affecting the fitting. Meaning its on the bottom of the hull and you hit a rock or log ( or any other object in the water ) smackin the flange off.

On the transom its not that much of an issue and certainly not for the deck ( unless you have a 200+ guy walking around your deck with steel toe shoes ).

For any fitting below the waterline you should have a seacock with it.

As far as your last pics that show Black Slime .. thats wood rot. You can try to dry it out and reseal your drains. Its a roll of the dice to remount your fittings in those locations without doing a splice core.

You will never get the water out from the wood around your cut out fittings ( I dont know why they bored into the wood other then they did not have long enough fittings at the time of production )

Your trans will have to be addressed at some point .. for you or someone else.

The surface of your fittings should stop the water from intrusion .. the wood on the inside should never get wet anyways.

But what is done is done.

YD.

Hi,

Aren't those holes wonderful? HEY LOOK, OUR FITTINGS ARE TOO SMALL, LET'S DRILL THROUGH HALF THE TRANSOM INSTEAD OF GETTING ONES THAT FIT.... ugh... People are lazy, and they just Duct-Tape and Bubblegum their boats. I'll never get it....

I am indeed using Bronze. If you go back a bunch of posts, you'll see a pic of one of them. This is why I took these 2 off. They were plastic, and, the awful holes as a bonus. The one thing I've been trying to find, is the best way to treat the exposed wood in those big holes, before I put the new fittings on.

Does it makes sense to, perhaps, make wood disks that fit the hole (with a hole in the center that matches the fitting), bath them in Epoxy, and plug it into the hole (then cover the backside with Fiberglass mat, and drill the hole in that as well (obviously)? At least it would now be thicker, and some new wood...

Of course, I suppose I could plug the hole, and drill a new one all together.... But I'd love to avoid that if feasible.

Agreed on the SeaCock. Budget is becoming a problem for me, but, I think these, especially the lower one, certain needs one.

The only reason I can think to put some wood back in there is to be able to get to the nut ring on the inside to secure the fitting. You dont want to spin the fitting itself after its been goo'd with 5200. You want to turn the NUT. Kinda hard to do when its imbedded in your transom.

You may have to do that if you cant tighten down the fitting with the nut.

I dunno if I would go all the way to glassing the wood plug on the inside though.

Hi YD, thanks for responding. I was hoping someone would chime in on that...

Your right, it's a real pain the @!$ to get into those holes.... but, also, the transom is half or less, as thick as normal, due to those bores. (spelling/terminology!?)... So, if I cut a 3" wood disk, epoxy her in, then drill into it. I've got normal thickness again, fresh strong wood, and.... like you said, I CAN REACH THE DARN NUT.

But, you think if I plug it, I shouldn't glass over it? I figured that would be good for added strength, and, more important, WATERPROOFING.... Though, if it's epoxied in, and I 5200 some on the backside of it... I don't think much water is getting to it... Final Thoughts? Plug = YES, Glass over it = ?

5200 is tough stuff - made to insure that things below the waterline don't leak. So using anything but 5200 below the waterline is sortof liking telling your doctor that you prefer to die of skin cancer because you don't want to undergo a 15 minute surgery. The cheap way out will kill you eventually.

As far as plugging the holes: if you have the skills to plug them and re-drill you should do that and yes glasss them over .

Standard 1" brass drain tubes come 3" long and you cut them a little long with a tubing cutter and install with 5200 using a tool to swedge the brass bue in to place.

Re: Boat had leaking PLASTIC below water Transom Drains. Can't find proper replacemen

If it were me, because I'm so ANAL, I would fabricate plywood Plugs for the transom, epoxy them in place so I would have a flat interior surface. Redrill the proper sized holes, 5200 everything and be done with it. But again, that's just me. But, if the wood is wet the epoxy won't adhere well.

I would make a wood donut like your talking about ( or just a plug and then back-drill the hole from the outside ) .. epoxy coat the crap outa it ( wearing latex gloves of course ) .. mix a batch of epoxy/cabosil mix and shove those things in there when its all still wet with resin.

Baby the resin back up to the fills with a brush or spreader ( cleaning up drippage with an acetone rag as needed ).

Done .. Install the fitting with 5200 fast cure and your golden.

I dont think Capping with a few layers of mat will really add much of anything to those spots. However .. If you have the resin and the glass then by all means go for it. Cant hurt and it wont take very long. But dont go out of your way to cap them if it means added expense is what im trying to say.

Good morning Friend,

I agree with you fully. This is the way I'm going to go. I am going to leave the small (correct sized) hole, in place, and install a wood puck, treated with CPES and Epoxy (the crap out of. LOL!), them in place. Them, I'll drill though, using the original hole as a template. Since it's bored out deeply. The new wood will make up most of the hole, and the fiberglass on the outside will be able to stay untouched. I've had it drying for days, and even had forced hot air running through them in shifts (I'd like to thank Mother Nature for raining 3 times, while I've got all the drains out and 4 holes I'm trying to dry!!). They were all wet feeling, but, no water comming out, and they feel strong. Drying does seem to be occurring..... so, I think I may have saved this in time, before saturation and Rot. I'm going to treat the area around the holes (And the holes) with CPES. I attached a pic of the general idea of my plan. I drafted this in a hurry, so, it may have error...)

As for Glassing over it... I got so tired of trying to figure out what the heck to get and not get, that I got EVERYTHING!! lol. So, I do have Cloth, Matt, and Resin.... I'll decide when I get that far.

I've been trying to afford all these darned Thru-Hulls and Seacocks, Adapters, clamps, hoses... holy smoke, it's been hard. This stuff is all made out of sacred ancient artifacts and gold!

Agreed. I'm totally going with this. Check out my reply to the post after yours.... I attached a pic of my plan. Everyones help has been priceless.

Better then OEM man !

Be ready with an empty small box ( for trash paper towels and gloves ) and go to it.

Its not that hard once it gets going really..

Re: Boat had leaking PLASTIC below water Transom Drains. Can't find proper replacemen

OK, so, I finally was able to afford some CPES, 5200, Marine Tex, and every other material imaginable.... and, I'm ready to plug and re-drill the holes, order the fittings for the other 2 holes, etc..... Here is my big problem. I am having a hell of a time affording this stuff. The 2 I have, for the deck drains, are the kind the hose clamps too... No Seacock. If I do the others this way, it will save me a ton of money, and allow me to do this job weeks sooner. SO..... do I use the ones I have, and do the rest this way as well. With serious marine hose, double marine grade clamps, 5200..... or, is this dumb, and I need to use the Seacocks on the 4 of them? This boat is over 30 years old and never had Seacocks... and, had PLASTIC thru-hulls....... So, one would think my method is a huge upgrade, and, likely to be just fine. But, I am not one to half *** something. Is this OK, but, Seacocks are the better way, or, is this, not ok, period.... Thoughs.

Any through hull fitting Below the waterline should have a seacock on it.

Its your boat though.

I personally would not use anything but metal fittings and seacocks below the waterline.

That is, without question, the leading opinion. Budget is a real pain. I think I'll have to go the Seacock route. I need at least 4. (5 if I decide to add one to the Livewell scoop, that is not problematic, but, does not have a seacock...) I already have 2 fittings, that are the clamp on kind. I'd have to ebay them.... Oiy. Time for some saving and shopping! =P

Re: Boat had leaking PLASTIC below water Transom Drains. Can't find proper replacemen

I have 2 of the holes plugged and ready for re-drilling. Anyone care for me to make a little video out of some of the pictures and clips I took, while doing it? Soon as I can afford the fittings, I will drill and install. I need to hit lotto....

Re: Boat had leaking PLASTIC below water Transom Drains. Can't find proper replacemen

I do understand the cost of doing this right .. But in the long run when your cruising around and that one in a million shot you have to run over debris that could smack the head off your through hull ..

Peace of mind for me.

Its an investment the you will Never have to pay for again.
