Thanks all for your suggestions.
Tried Mako Marine, always my first go to when Cummins Metropower cant help.
TAD is good to know about.
Nancy, I have been in touch with Derek rb2@gr5t East Coast Deisel.
Problem is I want to replace both turbos but everyone I have contacted can only get me 1.
pdecat, both turbos were hung up upon getting the boat back in the water, blowing black smoke. (My engines never smoke) I had to put a socket on 1 turbo to get it free. Then while rotating it it kept binding, not spinning freely. Upon engine shutdown the blades stopped immediately. The other turbo was hung up but I was able to get it to spin with finger pressure. Boat & engines are 1988 & I have had basically no engine expense in the 23 years I have owned the boat. So since 1 turbo is definately in need of replacement & the other 1 is "suspect" I will replace both.
Right now I have a source that says they can get me 1 new & 1 reman. I will give the hanging turbo as a core & have the better 1 rebuilt at some future date.
Thanks again for all the advice. I will post a replay after the swap out has been done.
