I think it's my year for problems.

Underway 15-16 hundred rpms engine runs fine. Pushed it up to 24-25 rpms black smoke comes out of exhaust and it loses power. Changed fuel filter. Still have the same problem. (also black soot comes out of exhaust floats on top of water)

Any Suggestions?

I had similar problem towards the end of the season last year. Black smoke over 2400rpm and oily sheen coming from exhaust. I wasnt losing power though. I have a 200hp Volvo. I wound up having some work done. Rebuilt the turbo. They said there was a small leak and oil was getting past seal. I also replaced all injectors as they all failed the diagnostic tests and couldnt be rebuilt. I had the aftercooler serviced. No more black smoke. Not sure what fixed the problem or if it was a combination of everything.
