Does anyone know where I can get a hose fitting for a mercruiser heat exchanger it looks like its about 1 inch 90 degree hose fitting that goes back to the exhaust manifold. Mine got dropped and flattened the fitting , I realize it will need to be soldered back on but need a fitting.

You sure you cant re shape it? If it is just copper tubing maybe home depot or real plumbing supply. You would be better off to cut bent part off and add to it than to try to resolder it into exchanger body. Pics would be helpful.

When I said flattened I should have said crushed, I will try a Radiator shop and see if they can reshape it but its flat Im not sure it can be reshaped I surely hope so.

Get a big pair of needlenose pliers and slide them in turn sideways and pull them apart to start spreading open. Then an assortment of punches or maybe big wood dowels you can grind a taper on and start doing body work...copper is pretty workable. You may be pleasantly surprised. And when done it only has to be strong enough to hold a hose and some water.

Maybe braze a bung onto tank then you can get a stainless 90* fitting to screw into bung.

i don't know about brazing. copper sheet metal. i would think you would burn it up. but you could solder most anything into it. a bung or a brass pipe fitting. if it is that smashed cut the 90 degree part off and straighten the straight piece sticking out of the tank. it would be best if you had a piece of tubing to fit the add-on piece to instead of trying to solder it straight to the side of the tank. make sure you get solder with LEAD in it. it sticks and seals so much better than the politically correct stuff. just don't drink the antifreeze...you will get lead poisoning.

Those heat exchangers are fragile, as you know. I'd look around and post in the wanted section looking for a heat exchanger that's been blown due to freezing. Cut off what you need and have it soldered onto your unit.

Call Justin at Jordan Point Yacht Haven or Wayne's service guy at Nautical Marine.

There was a used exchanger on craigslist this weekend, houstion, tx i believe, if not either austin or dallas. He was asking $ 400.

I kept thinking about this after I posted. If it took that much of a shock/impact when it fell, I'd be seriously worried about the fragile tubes inside when it comes to their integrity.

I'd have it pressure tested somehow first before you do anything to repair it.

have no idea if this will help but scroll thru their catalog.
