My ancient can of blue antifreeze for the TR7 is Comma Super Coldmaster concentrate. It is 'pure concentrated ethylene glycol....
Both pure AND concentrated ? Must be good stuff. If it's pure it doesn't need to be concentrated ?

Ah - you missed the typhoon?
My ancient can of blue antifreeze for the TR7 is Comma Super Coldmaster concentrate. It is 'pure concentrated ethylene glycol....meets BS 6580-1992.....mix as required ..... A third of this plus two thirds water protects to -18degC, more than enough for UK!
Probably cheaper to buy concentrate rather than the ready mixed stuff. But why for wood?
Re "why for wood?" because I ...er...got wood.
I also had a lot of moss, lichen, and some young brambles, but they are mostly gone now.
More importantly, I had/have wood rot, though stupidly I didn't keep a sample of the fruiting bodies, Probably wont be able to identify it from a smartphone photo taken in poor light, but it looked like dry rot to me.
Possible saving grace is this is a very early GRP boat and has limited structural timber (later ones mostly have end-grain balsa cores which turn to mush) so I might get away with it.
Decks dont seem to be flexing much yet but I didn't want to jump around too much in case the boat falls over, it being a bit stern heavy on its launching bogie, having originally had a 2-stroke inboard engine, replaced with a Yanmar diesel.
Ethylene glycol apparently has antifungal action, there being a lot of internyet legend on people treating athletes foot with it, and AFAIK you cant buy anything more effective, though I intend to also use a lot of salt, which is free.
I might be able to homebrew something more toxic, but I doubt I have time, and I might end up having to sleep with it. (and/or the fishes).
Bit concerned about the dye, since I wouldnt want my (rotten) teak trim going blue or green, though it probably wont penetrate that much.
Pink would probably be preferred.

We've heard about ancient wooden vessels being rescued and treated with 'glycol' to preserve them for perpetuity, but as the stuff is miscible with water in all proportions, I am wondering how permanent your applications will be. Or are you planning a fresh coat every spring ? :-)

Isn't the Mary Rose preserved using glycol?
Edit: just had a look to see what a "Trident 24" actually looked like, nice looking early grp yacht. Is it any good Ed?

Supposed to sail quite well, and quite pretty, but, as a corollary, rather cramped.
Whether this particular one will be any good will depend on what happens with the rot,
i.servimg.com/u/f28/18/14/95/21/t24_co10.jpg
and whether the engine is savable.
The boat was in a terrible state, and I should probably have haggled. Was 500, with some gear and a mooring with some life left in it.
What I didn't fully appreciate was how absolutely atrociously random the bus service is to its location, an especially critical factor in miserable Scotland, where an hours wait could literally kill (me anyway, acclimatised to SE Asia)

I'd think if it wasn't water miscible it wouldn't work, since it will have to penetrate wet wood, and even nominally dry wood (seldom found on a boat, and especially this one) contains quite a bit of moisture.
The "official" recipe includes borates, but I think borates are now subject to the "professional polluters only" prohibition.
I'd think if ethylene glycol wasn't in anitifreeze I wouldnt be able to buy it.
This isn't a finish coat. I dunno what I'll do about that, and dont need to yet.
Maybe never
And maybe nothing

Engine access is lousy, probably almost down to modern cars standards, though I might be able to improve it in the future, if there is a future..
I dont THINK I can do a conventional gravity oil change, so I suppose I'll have to try and suck it out, though I dont have anything for that.
Its very black (but then it is a diesel) but theres no obvious water, which is nice as far as it goes.
I vaguely remember seeing some kind of pump in Lidl, but its unlikely to be in stock when wanted.
Yáll got anything to recommend?
I have an enema syringe which MIGHT do it. The tubing that came with it is almost certainly too thin walled, but I might be able to get some more substantial stuff.
I'm told the installation was done by a marine engineer 15 years ago. Apparently they didn't cover starting handles (to be acquired) in his apprenticeship, since hes boxed off access to the crank end.
Neat but non-operational

The PELA pump (or equivalent) will be your friend with this, providing the oil is nice and warm. A cheaper solution might be one of these for about a tenner:

Thanks. Draper do one with valves for about the same but Screwfix is more likely to be available local retail. The oil is going to be cold, b***** cold if I dont get it done soon since the weather is due a dive.
Manual says API CC or higher, 15W40, with a TBN >9 (which is pretty high), my kind of oil, though probably more widely available in Taiwan than here.
Interestingly, if you like that sort of thing, it also says
“Never use API Service Category CG-4 or CH-4 oils.”
so I guess that means CC, CD, CE, or CF, assuming they all exist. Wonder whats wrong with G and H. Perhaps no ZDDP?
Theres a jug of some modern skinny 5W40 stuff in the boat which is probably what its had. Wont run it on that if I can help it (except maybe just to stir up the sediment when/if the time comes) but it should be OK for storage,

I've never seen a recreational boat that had a gravity oil drain option, they all need to be pumped out. I doubt if there would be enough room to swing a starting handle.
Tell a lie, hired a narrow boat in the 70s that had a single cylinder diesel (ex concrete mixer I suspect) mounted at waist height in the centre cockpit that had to be swung by hand and de-compressor dropped!

You say 'non-operational' so presumably you can't run the engine to warm it up ? Sucking or pumping it out won't be fun either at 15/40 ....

Non operational refers to the starting handle, a standard feature on small Yanmar marine diesels and probably a feature of this one, though I cant see if the crank has a suitable end, and it might be too close to the floor to use a handle, which I dont seem to have.
Its raw seawater cooled, and is on the hard, plus theres no battery, and no starting handle .Could probably rig something to cool it but attempting to start it will have to be deferred.
Priorities are:-
Rot treatment (salt and antifreeze)
Change oil
Flush cooling system and add antifreeze, (perhaps also oil?) to it
Replace engine zinc anode, if I can get one in time (probably not)
Rig cover
Disconnect through-hull fittings in case of flooding with precipitation
Mouse running rigging and get it down
quick corrosion suppression on mast step and (triple) keels
Fly out Monday

Enema syringe worked OK, jusf slow, but the tube that came with it (Ebayed here in The Yook since pharmacists claimed shifty ignorance of syringes) was a pain, so I bought a Screwfix bigger syringe kit, not having time to look for suitable tubing on its own. 15 quid so an expensive piece of tubing.
Screwfix tube was too wide to get down to the oil at the bottom, (though that is rather what its for) but using the enema syringe tube inside the Screwfix tube as an extension got it done.
Whats the betting on Halfords knowing the TBN of their 15W40?

I was politer to the humans, who once again "needed the registration" and predictably had never heard of TBN, and couldn't think of a single entity in the organisation that might have.
So the company sell a technical range of products, but apparently dont have any mechanism for fielding/ raising technical queries on them.

Ethylene glycol apparently has antifungal action, there being a lot of internyet legend on people treating athletes foot with it, and AFAIK you cant buy anything more effective.....
The various -azole creams (e.g.miconazole) might be available over the counter, or if you don't mind the stinging, surgical spirit is cheap.

Long John Silver had half our chiropody requirements, but then he also had shivering of the timbers, and psittacosis on his shoulder
