Anybody have any of these or know where I can get these.

Sorry, that was supposed to be a picture along with the post. Can't upload for some reason. I need the two brass 2" 90 degree long elbows that attach to the heat exchanger(2" brass pipes on the seawater side). Mine have pin hole leaks.

 

[Boatsb]

Mine too. You don't want to ask how much for new ones either.

I will probably be removing mine and inserting new pipes and using hose to make the run.

 

[mtadamek]

Just curious. How much?

 

[Boatsb]

You need to take the old fitting out and remove the pipe. That will probably require a trip to the machinist to get it spot on. After that new pipes can be attached with solder. having them made as hose barbs is something I am looking at too.

You won't believe this but if you get a blob of soft solder on the hole in the normal way, it may hold for ten years or more...I have done that in the past....at least it's a short term solution if you don't have time for a more permanent fix....you'll have to be sure all water is out so you can get the spot hot enough to adhere solder....

I will try the solder. I have one with just a single spot on it, so this should be a good fix. I am checking on some originals, but I think we are going to experiment with pvc on the other 2. I have a couple extra flanges and a little extra brass tubing. Going to clean up the flanges and solder in a small piece of tubing onto it and use 1 1/2" sch 40 pvc coupled with a short piece of hose. It will reduce the flow since the ID is different, but I will have to see what it does to actual engine temp when installed.

Silver solder is a stronger and potentially more permanent repair but I have always been afraid the additional heat required might do more damage than good....a nice thing about soft solder is that is so fast and easy to apply and even reapply and add to if necessary...as long as there is no water inside...
Always sand or buff the exterior clean and shiny...use acid flux to assure further celaning and a firm adhesion of the solder....

We had several pinholes appear over the years in a copper riser on
6V53's....more of a damp ooze than an actual leak...believe it or not we'd repair perhaps one of these every five years...when green corrosion and dampness appeared on the outside of the water jacket....likely we repaired three of four and never had to go back to one already "fixed"...I don't remember how long the oldest repair lasted but it was a good deal over ten years as we had that boat and the same risers for 22 years!!!

I suppose you could also solder a thin piece of copper, perhaps a small piece of flashing of the type used for roof corners...but a patch of just solder worked for us....

and perhaps one of the epoxy type repairs could also be a good approach...I used one on the exterior of a belt driven raw water pump many years ago....dried it with a blow torch and we were underway again in about an hour!!!!!

Someone posted recently about spares (Angela??) and stuff to bring to the Bahamas on a trip....any of the above items would be good additions to carry aboard and have a long shelf life....

What about something like JB Weld? I've seen it used to fix a cracked block, and I've used it to fix rusted out exhaust manifolds on a car and had it mast MANY years without needing to be fixed again, and I didn't even do a very good job of cleaning the interface before slapping a blob of it on. I did of course smooth it out and feather the edges as best as possible by hand. Might that work?

 

[mtadamek]

I tried Loctite epoxy. Cleaned it up real good, brushed 2 coats on and figured I would give it a try. Did not work. These holes are soooo tiny, they weep more than anything. JB weld could work, but the expansion and contraction of the tubes due to changes in temp make it very difficult for any type of epoxy to hold. I even thought about getting the tubes brass plated, but I figured a longer term fix is in order.

 

[stormchaser]

I'd say give one of the "fixes" a try befoer coughing up the dough for a new one. I'd certainly try the JB weld trick unless someone could tell me a good reason NOT to try it...that shit is INCREDIBLE.
