Thanks Tony, I see and understand. 1st off, I am not a mechanic, just a boat owner who likes to know how to maintain it, diagnose issues and fix things as needed. As to the salt water getting to the turbo, I’m not sure how to change it though. There is very little room for adjusting the exhaust system. I will give the matter some thought and talk with other mechanics. On Monday I figured out that one of the injectors failed. Made sure that cylinder was visibly ok than swapped the injector with another cylinder to make sure that it was that was it. It was. Thank goodness.

I actually did read the article. It was very good. My exhaust elbow and turbo is original to the boat which makes it 30 years old now. 2500 hours on it. I qind I’d figured that is just normal wear in a salt water environment. Basically the boat sits for 5 months a year. I figure normal condensation and age gas something to do with it as well.

I didn’t take a photo of the new exhaust housing with turbine set it. Visually the distance between the new housing and fins were roughly a millimeter. Last year I had to replace the heat exchanger, that was a job in itself. Off the shelf was 1/4″ too long and I ended up have to have it custom made.
