This happens in the first 15-30 minutes running, after this is almost imperceptible.
The model is an Onan 11 Kw with 1200 hours serviced at 1000 hours at s amel 55#003
But the interesting is: come more black color from water colling hose than from fume hose!...

We had similar carbon discharge from the Onan during spring start up, powder as well as chunks of carbon. Ultimately the Onan would not start. Opening up the exhaust mixing elbow revealed huge carbon buildup leaving only about 1 cm diameter air passage for the exhaust. Not at all uncommon when marine diesels are not run periodically under high load. That would be the first place I would look.

Can you give
more information? Is it when you start the Onan or all the time? Is it oily or
carbon? What model Onan and boat is this on? How you done anything to troubleshoot
and if so what were your findings?

Dear AMEL Group / Owners
I appreciate your ideas about the reason I have black water comes from my onan
11 raw water exhaust hose
And from exhaust fumes too ( less quantity )
The Onan was 1200 hours and was serviced at 100 hours
Thanks in advance
