I came into a project boat. A catamaran with 2 2003T Volvo Penta Turbo Diesel engines in it. Both motors run good, but 1 motor has an issue with it's turbo.
Before I bought the boat, 1 motor needed to be rebuilt. In the process the turbo was destroyed and discarded. A new(used) turbo was purchased and installed on the just rebuilt engine. The engine would not run properly. This was the condition when it was sold to me.
I have determined that the engine actually does run fine, with the turbo removed. This is true because the turbo is blowing air in the wrong direction!! Sucking air out of the head instead of blowing it in! This is where I become lost.
-Are there different Turbos for a 2003T Volvo Penta Turbo Diesel?
-Is this the wrong turbo?
-The way the piping is, I can't just change where the air goes. Is that what I need to do, even if it won't be like the other engine then, and have more elbows & bends, etc?
-Can I change the impeller?
