Chuck can respond for his situation, but in my case, 10 yrs ago the exhaust elbow came apart while previous owner was motoring out of marina. I happened to be crew at the time. Big mess. PO had a plumber friend fabricate a replacement exhaust elbow and mixer out of regular pipe I assume. That's what I now have and it needs to finally be replaced before I start more extensive cruising next summer. Plus, I suspect the exhaust may be getting clogged. Jeff Laman

What made you decide to replace it? Problems or trying to prevent them?

FWIW, it wouldn't match my Universal M4-30. So I'm replacing the exhaust riser mixing elbow with the same thing that lasted for 34 years. It has an iron 3 bolt flange at the engine, iron pipe nipples and aluminum casting for the elbow made by Barr. It's much more compact than a SS aftermarket elbow would be. Parts should arrive in a few days. I may get some SS nipples for it, if they're not too pricey. Chuck Scheaffer, Resolute 1989 C&C 34R, Annapolis On 07/16/2023 7:12 PM EDT Jeffrey A.

If this topic has been discussed here previously, my apologies -- I attempted a search of the archives but not sure I am conducting the search correctly. There seems to be debate about stainless steel vs cast iron and welded SS vs cast SS. There is a complete SS kit at https://hdimarine.net/product/gm-kit/ that appears to be high quality and reasonably priced (for a boat part...). I will be grateful for any advice on source for the exhaust elbow/mixing elbow and cast iron vs SS vs cast SS. Also, advice regarding the replacement job as I will do this myself. Thanks.
