Issue with engine power after replacing mixing elbow

https://www.ebay.com/i/352423345141?chn=ps look at this design and resurch, why yours is diferent.
that is what my deisel has, I like it more, there is no way, water gets into engine. mine is kubota, same basic
design. https://www.betamarinenc.com/all-engines/ look how and where water inlet on elbows attached. betamarine marinizing kubota engines, very simple and foolprooph .

smoke comes out just fine as does cooling water. will have to get back to you on the muffler.

https://www.sailmagazine.com/diy/maintaining-your-diesel-exhaust very good info, read it, pay attention to position of motor to waterline.

Your old exhaust elbow does look very tired to say the least. I don't think that it totally restricted the exhaust air though. The engine couldn't run with a total restriction. What commonly happens with the GM series elbows as they begin to coke up, the water injection nipple is the first to be fully blocked. This causes reduced exhaust water flow and increased engine temp.

the elbow has been replaced with a brand new stainless steel one.

I had a mixing elbo clog so bad omg that the engine would not start or run so yes yours was not clogged completely but just enough to let it run.
I would say sounds like everything is running good and some thing with the throttle changed
and need to recheck the cable adjustment.

My son had a 2002 , 306, with the 2gm 20. His mixing elbow was really clogged. I think he paid $150 for a new one. Check with HDI for a stainless steel elbow.

Hope you are all sorted now.....it sounds like you caught the problem early enough not to do any damage. Relax and enjoy!!

running good. still have to find time to check the throttle and other minor items. Will keep you all posted on my lessons learned.
