Hi there, Does anyone have the contact details of the guy that makes the S/S Yanmar exhaust elbow for 2GM20F? Or anyone know where I can get a cheap one?

Thanks.

He was selling them on trademe. Had a look, nothing. It was about 4 years ago though sorry, trying to wrack the grey matter to remember where he was but I think he was south island. Will try to find out.

Found it: ($150).

OK, located another email (2013!) and he didn't make it but might know who does?. Lives in Kerikeri. I shall now go hide my own easter eggs! Good luck.

So, on further research it looks like the following models all use the same elbow

Used on the following engines: 2GM, 2GMF, 2GM20F, 2GM20FUE, 3GMFYE, 3GMD, 3HM, 3HMF, 3HM35F, 3HM35, 3GM30, 3GM30F

 

If this is the case it makes it a bit easier to find one.

 Is it simple? Is it cost effective? Yes. Great to see some creativity over the "get a new one" perspective.  :thumbup:

welded 316SS is not a good idea in this application, the chlorides in the salt water and the sulphur residues in the exhaust will vigorously attack the welds.
Welded steel pipe galvanised is a much better budget option

Oh what a coincident, I just checked my one yesterday... I shouldn't have. One more thing on my list. I think I'll make it from S/S tubes, TIG welded and purged. I might make two just in case.... It will be a mission to remove it.
