Re: Black water comes from Onan 11 exhaust hose

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?



With best regards,

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
