7,3L diesel black smoke

[mercruiser]

I have a mercrusier 7,3l D-tronic Diesel
simular like Powerstroke 7,3L

I have probelm with black smoke.

It runs good but smoke a lot..

Is the problem injektor realated or low compression?

Depends but I think we're going to need ALOT more info.

Black smoke usually results from TOO much fuel or TOO little air. I am not familiar w/ the motor you're describing sorry I can't help more.
