It would help if you gave us the engine model / type

ASAP Supplies in Beccles usually has a selection in stock.

Boulters maybe worth a shot too, they try to keep in stock engine parts, they have a van and tug boat and may come out https://boulters-chandlery.co.uk/

Looks like a BMC on a PRM gearbox.  Quite an old one as I see there are both engine and gearbox oil coolers.

This "water injection bend" is not a standard part and was made up, by someone, when the engine was converted from the old front heat exchanger to a side mounted one.

It has obviously failed because there is too much length of hot dry exhaust before the raw water cooling joins it.  Hence the need for the asbestos lagging.  It would therefore be better to talk to someone, such as Peachments, about fitting something more suitable. I have seen these castings before but I don't know who made them.  It may have been Herbert Woods as they were the BMC agents in East Anglia at the time.

What I am trying to say is : rather than just find a new one, consider why it failed and see if there is a better way to do it.

It could also have been caused by vibration, as the whole affair is only supported by the flange coupling on the exhaust manifold.

Looking at the photos supplied I get the impression that a gentleman by the name of Heath Robertson had a hand in the design of the failed part.      LOL

Good luck with the repair and I hope it doesn't cost a fortune

You probably hav'nt just made his day.  Maybe stuck on a boat in this weather with possibly no heating and maybe skint to boot.  Poor bugger.

Agreed - However don't really see what else we can do to help other than the advice that has been freely offered

Let's just hope he is safe and warm x

Essexmatt.

I have been contacted by a non-forumite who thinks he might have one that came off a small Bowman heat exchanger.

He needs to know the diameter of the exhaust outlet and the raw water connection.

I have just remembered that the original BMC (Austin) engines were marinised by Newage.  The 1.5 was called the Newage Captain and the 2.2 was the Newage Commander. This may help in identifying parts.

I believe that Thornycroft marine parts came later.

My guess is that this is a part cast locally for Broads use and Herbert Woods may have used Brook's foundry in Ludham. Not much help as this closed a long time ago.

I think it is worth going to Herbert Woods and see if they still have something lying under the bench in the engineers' shop.

[Vaughan]

Just had another thought : Barnes Brinkcraft still have a company on their books called Barnes Marine Units.

They used to sell re-conditioned BMC 1.5 engines, fully marinised, to boatyards in the 70s.

    a few years ago i sourced the same part for my BMC from martham boat yard,  very helpful people

[BroadAmbition]

Essexmatt if it fits he says it’ll be foc. All you have to do is collect. 
Need those measurements

We had this problem with Lady Linda when we bought her 10 years ago. Toby at Moonfleet of stalham made a new one out of stainless steel. Toby has since moved on to I know not where. I have no idea of the cost as it was all part of engine service, bow thruster and electrics upgrade etc costing about £10k.

I think your best bet Matt is to remove broken part and try to find local marine engineers who will know who can make one for you.

As Vaughan has said, your engine looks like a BMC 2.5. If it’s like ours it’s inclined at about 45deg and the water injection bend is far from standard.

Just one question,   dont shoot me for asking but has Essexmate come back to all of you very helpful people?

[ExSurveyor]

Apparently not, maybe limited WiFi or the problem is solved.

Hopefully we get an update at some stage.

[BroadAmbition]

Not got back to me. His first post and plenty of help offered too

Griff

[Vaughan]

Not the first time this has happened lately - I noticed it myself.

Still, it keeps the memory cells ticking over, at least!

Hi, I am told by a man with over 30 years experiance that it is not "Home made" but that it is the Thorny Croft version used on 1.5. 1.8 and 2.5 BMC engines. Sadly no longer available unless you come across the cast aluminium versions but they dont tend to have a long life. Happy hunting.

Thank you for entering the debate, at this late stage.

One way or another we are talking about an engine of the mid 1950s, with a Bowman heat exchange conversion which caused modifications to be made to the pipe work. Some such modifications were successful : some maybe not.

Maybe a supplier such as Peachments will have developed a better solution to the problem, if someone asks them?

It reminds me of the engine I used to have on a previous boat. That one was blue too.
