So the other day, exhaust filled my cabin. It appears the the exhaust elbow has rusted. Has anybody had this happen to them?
Exhaust elbow rust
- Thread starter Tom23300
- Start date
Looks like the joint cracked off just above the exhaust outlet.. The thing has a left handed thread on one end and a right handed thread on the other (I don't remember which is which) so it is not common. The Yanmar part number is 104214-13580, and costs about $40. Best to get an outlet gasket (part # 128370-13201about$8) and pull the outlet to get at the part that is stuck in the threads.. Good Luck
If it broke at the nipple then chances are the U-elbow is probably towards the end of its life. Get a new one, a nipple and a gasket and as per Kloudie's suggestion remove the outlet to make it easier for yourself. You can use Yanmar or get a stainless steel one from HDI Marine. HDI sells it complete with the nipple.

Take the riser off and look in it if its clogged order a new on pressure and heat probably separated it

I'll second the recommendation for HDI; great service, beautifully made parts, longer life and MUCH less expensive than Yanmar
Yes. And it always rusts out from the inside. It made a disgusting mess in my engine compartment from a 1/4 inch hole. Four years later I am still finding black spots that need cleaning. I replaced the entire mixing elbow. It was hard but straightforward work. Once I pulled out the old one it was completely rusted. I would definitely replace it.
When I had to do this years ago, I used fiberglass elbows. So far, so good. No rust.
Making the black tank out of aluminum didn’t make much sense either.
