I purchased my boat last summer and I did have some problems with the engine.
There was very dark smoke comming out of the exhaust as well as some black soot. I could not throttle up fully, and the engine would cut off.
I rebuilt the injectors, replaced/cleaned all filters, and I cleaned out the diesel tank. I got new fuel from a truck stop where much diesel is used, so it will be fresh.
Now I can run full throttle. There is smoke out the back, but there is much less of it, and it is light in color.
Still not sure if this is correct for this MD6A engine.
One thing that I never did resolve is that one cylinder seems to heat up faster than the other. When you start your engine from cold, if you put your finger at the top of each cylinder (next to the injectors), you can feel the temperature as each cylinder heats up. Mine are not even. Compression is very good.
But, the engine seems to work well now.
Hope this helps.
