Raw water cooling elbow

[ageless]

I have leaking cooling elbow from corrosion. the only place that corroded was the splitter on both motors. Anyway, 4 welders haven’t been able to get an arc, any idea what material the elbow is so I can have replacement spiltters made?

Bronze and copper.
I stripped and epoxy / cloth repaired one.
Good patch lasted near a year and doing well until the owner had a new (whole) assembly made.

From your picture, you have the TAs. I don't think the Ys from Sams are large enough.
BTW, I have 2 of those same stainless Ys (new) collecting dust.

There was another thread on this last year also.

Concur on the epoxy/JB Weld for an intermediate solution.

I’ve exceeded the JB Weld stage, it’s time to do a proper fix

You’re correct on the Y from Sams, they use a smaller hose than the 2” mine have, mine have a year or so of dust on them, as well

Try a good radiator repair shop. They should be able to clean & repair back to good order.

Try Lenco Marine Coolers in Amityville NY (Long Island) .
Have had them make various custom parts for us over the years.
Also, they made/make a lot of parts for the OEM's so they might already have a pattern.
My experience has been if they don't have a drawing/pattern they are going to want your part to copy.
Call them, not very www savy.

Along with Lenco, try Marine Manifolds in Farmingdale, NY. Send them the old one and they will make an identical product in material of your choice. In the past they made exhaust elbows for a Perkins of cupro-nickel at a reasonable cost.

I tried 2 marine exhaust companies local and a $3000 quote came from them. NOPE!! Found a welding shop that can braze a new Y section on so that’s in the works. I’ll keep everyone updated.

Please remind your shop that warm salt water will be passing thru their work.
Some rod wire formulas will react different others.
DeAngelo always did my work. Western Branch NC has a favorite shop also.

These guys have bought up many of the old spec drawings for a lot of the exhaust elbows, risers, etc used on Hatteras and other boats (or so they claim).

If you send them the manufacturer and part number they can likely make you a new if they have the spec sheet for it in their files.

If you get in a tight use the right size raw water hose reduce down with a bronze tee fitting to smaller hoses on the end cheap and long lasting.

DeAngelo is 3 weeks out and didn’t seem too interested, I think that’s why the $3k price, got another from metcalf marine for $2500. I told him not to do any work until he discussed with me his material of choice and he does know its a cooling elbow for salt water

The only DDC part number is the bronze flange that bolts to the heat exchanger. The plumbing after that coupler was custom order by Hatteras. BTW, that flange is no longer available thru DDC.

It looks like a hard copper bell reducer shaped around the 2 - 2” tubes. You can’t tell with the paint on it if the connections are sweated or brazed. Curious to see the new one when fabricated.
