Thanks guys. That is why I came to this site, to keep the newbies like me from making a major mistake. I will have to print some more $ and get the new elbows made. Would anyone have any recommendations on where to get this done on the east coast, Annapolis, MD?

Tony, I know you guys can handle this job, any idea on how much you would charge for 2 custom elbows?

Thanks in advance,
Steve

Finally got new turbos from Cummins. Wow, what a difference. My old turbos really were in bad shape.
Exhaust redesign will have to wait until this coming winter. Already spent to many $ this year. I boat in the upper Chesapeake Bay so the water is not that salty. I will religiously flush system and drain exhaust elbow this season to minimize any damage to the new turbos.

So here is my status and question. All components in the seawater circuit serviced, pressure tested and reinstalled. Will install new turbos and exhaust elbows this week and refresh the engine coolant. Question is, boat is currently in the water and winterized. Can I run the engines to get the air out of the freshwater cooling system and also travel approximately 100 yards to get hauled out without using the seawater cooling? Seacocks are closed and impellers are removed. Need haul out to get props off to be redone and new transducers installed.

Thank you everybody for the great information and helping me through this for my first time. I will start reading the articles on exhaust redesign and am working with local Cummins dealer on getting some new turbos. Now for the good news. Took apart one of the aftercoolers tonight and was shocked at how easy it came apart and how clean it was. Already have the Seaboard rebuild kit to clean it up and put it back together (as per Tony’s protocol of course).
Happy New Year

Many issues to discus but want to start with the most serious first. Pulled the exhaust elbows today, we had to cut off the bolt heads because they were rusted so bad. Honestly I have no idea what to look for, but to me the elbows look pretty good. They were dry and had some carbon build up. The turbos on the other hand, they look bad. Very wet and not sure if its rust or carbon build up on the inside. It looks like they are rusting from the inside out. Could the wetness be the engine coolant leaking in to the turbo?
