Water jacketed riser elbow repair/ replacement

[38 HAT]

Hi All, it appears I have a leak where a small amount of raw water is leaking back to the turbo housing and during winter layup is rusting exhaust side of the turbo. It is stainless steel and I was wondering if they are repairable. Also it looks like DeAngelo marine in fla repairs and fabricates but I live in CT so I'm not sure how I could ship it to them. Are there any company's in my area that I could contact for repair or fabrication? Any insite would be very much appreciated.

I don't see how it can leak back unless you have a crack somewhere.I would take that one off and send it to D' Angelo to have them test it via ups fed ex they will get it. I don't know of anyone in our area that does that fabrication. good luck

FYI - I recently looked into having new ones made at Marine Manifold in Farmingdale, who were very pleasant to deal with. From what I gathered, stainless steel has about a 10 year life span in salt water. New custom fabricated stainless steel schedule 10 ones for my 400 HP Cummin's 903's were about $2600 a piece. Mine aren't leaking yet, the original 40 year old monel ones, and I will be waiting until they do leak to replace given cost of new ones. A cheaper way to fabricate is not having them full water jacketed, but to only weld shower head on end. You wrap with a blanket the tube from the turbo to the shower head. Having them made out of monel would at least double the cost.

Waiting until you find a leak can cost you an engine. Ship them where you feel most comfortable. We used Alvern Marine and were happy.

I've used Marine Exhaust Systems in Riviera Beach FL since the mid 80's, always have done great work. Eliminate as much of the water issue as possible, go with the hard coating on the outside. Don't mess around, get it right before water gets into the engine etc.

Marine manifolds in Farmingdale is great and near you. They made new risers and elbows for my Crusaders. They used copper nickel. I am told they will last forever. Four years now and they are like new.

Marine Manifold in Farmingdale NY made new SS exhaust risers for me and even met me down in the Middletown NJ area to deliver them. He was visiting family or something. Did a great job at a competitive price and very pleasant to work with.

Marine Manifold made monel manifolds and copper risers for my old seamasters. Great Guy

Thanks guys for all the input, I got a quote from Alvern Marine. $980.00 made out of 316L stainless. Very Nice guy to deal with.

x10 or whatever tribute to marine manifold we are on. cupronickel exhausts on my 871s going on 16 years and no issues. I do drain them after every run.

Tom how's the boat? You should start a thread and post some pics of all the work you had done. Hoping the weather breaks soon as I'm getting withdrawals from lack of burning fuel.

Hi Jack,

Boat is still down at Slane. It's been a long two years since Sandy but I guess good things come to those who wait? I emailed him Tuesday to get an update on my scheduled placement back in the water. He is going to send it to a guy he knows down in New Bern to install the new hard top he made for me, outriggers and enclosure. Can't run down the road with them installed obviously. I plan on going down next week to do a final inspection before it leaves High Point. I'm really looking forward to getting back on the water and fishing my own boat. I will try to set up a thread and post some pics. It looks like a new boat! By the way, the 62 is even more impressive up close and personal.

I know Tom still has her and she was just about ready to splash. How are you getting her home? Oregon is closed and Hatteras isn't much better. Sucks to not have an option to duck inside if you have a problem.

 

[TomT13]

I'm not in any hurry to make it home and would like to take a week or so off to make a cruise out of it. I was thinking the ICW to Norfolk then leave the boat in Annapolis for a week or two to enjoy it there. Then a quick two day trip to Cape May and finally Atlantic Highlands.

Scott, if your considering that route, although it's not common on a pleasure yacht (possibly due to space) it us common on commercial boats and often carbon steel, not stainless. I DON'T recommend carbon steel at all. The standard setup is is a flange connected to the turbo and in the down hill section the water is injected. More pipe length is needed to using this type of installation to lose best to allow for the exhaust hose to have a short life, or burn up.

As a mater of standard procedure blow boat builders' such as Catalina, Irwin, Gulfstar, Hunter etc, use this all of the time and 99% of the time use carbon steel. This type of a blow boat setup last as much as 20 year. And the material is often just plumbing pipe.

The 20 year is, of course, impacted by the low engine hours, sailing when there's wind. But as Dylan said "Rust never sleeps".

I'm on vacation now, when I get back I'll e mail you some photos so you can get a better idea of what an installation looks like.

Spend some time in the area before you leave. Beaufort is a nice spot, Cape Look Out, Moorehead City, Atlantic Beach etc. From there I ran the Sounds up to Coinjock. Open water so you can run but there's not much out there if you wanted to make a stop along the way
