Below is an exhaust mixer elbows off of my starboard engine that I removed several months ago while working on one of my turbos.

Obviously it has seen better days. I suspect the others are in about the same condition. At the time, I looked around for a set of replacements and was finally quoted $1,800 per each by a local marine exhaust fab shop. (Not sure if this is in-line with typical cost or not.) Well, not having an extra $8K laying around to spend on exhaust mixers at the time, I reluctantly went ahead and put it back on.
The outer water jacket shell doesn't really appear to be in bad shape and if I knew what alloy it was constructed of I would just cut out the inner exhaust pipe and tig weld in a new one. Otherwise, I will likely just fab a set of new stainless ones myself.
To that end, I was wondering if anyone might have an old exhaust elbow laying around that I might be able to cut up and use as a template. The Kay Industries part number etched into this one is SK2046-4 with a mfg date of 7/28/75. I'm located in LA (Lower Alabama) but venture regularly around the FL panhandle and south MS. I would also be willing to cover reasonable shipping cost. I am also open to other suggestions.
Thanks

See if Hailey Wilkerson of HDI marine (306) 824-0800 can give you a price. They will need engine make and model. They shipped me an odd generator elbow that was quoted to me from MFG of $1200. I paid $390 which included shipping. Original part was cast Iron, new is Cast Stainless Steel!

Re: Old Exhaust Shower Head
He has a custom exhaust part manufactured by Kay Industries so the part # probably isn't going to help.
Might be able to come up with a generic type shower head piece with the same inlet and outlet size with similar angles and then modify or manipulate what they dump into if needed.
We wiped out a 12v71 because it ingested water from a hole in a Kay elbow/riser, it was not leaking on the outside at all.
The way to go now is to eliminate the outside water jacket and use the hard coated pipes instead.CRICKET

Re: Old Exhaust Shower Head
Try them all, Marine Manifold in NY, Marine Exhaust Systems in Riviera Beach FL, DeAngelo in Ft Lauderdale, etc. Somebody told me there's an outfit in South Florida that's doing exhaust much cheaper than the rest, just can't remember the name., Maybe an offshoot of DeAngelo???
