Hints from Admiralty Yacht Sales -- Diagnose your diesel engine
While this is not intended to be an exhaustive list of methods to diagnose your diesel engine's general health, there are several non-technical techniques to check the health of your engine. Make sure your engine is warmed up before diagnosis.
Diagnose your diesel engine's running condition by the color of its exhaust:
Black smoke - Indicates unburned fuel/highly loaded condition
black soot in the water
I had this problem with a generator. The genset seemed to run just fine except that it looked like a tire fire in back of the boat and the water had an black soot over it. After two generator companies came out and checked the injectors and everything else you can think of they said we needed a new genset, this one was just wore out.(1750 hrs) After puting the thing back together again (2ND time) I just happened to check the air filter screen and it was completly closed with exhaust soot! So I cleaned the filter assembly and it was perfect! No smoke, no soot , just clean water out the exhaust. I guess you don't always get what you pay for. These guys weren't cheap. So I learned something new.The companies you hire don't always know more than you and make sure the filter screen is clean.:)
hello funsailthekeys, I do think the genset company knows more than we think they know. its their business. what probably happen is this: send a service engineer and he sell spare parts, send a sales engineer there and he sells a whole new genset. so I guess it make prefect cents to send a sales engineer. ;)
