The exhaust smoke is black when accelerating under load/ underway. The starboard engine exhaust is clear under load.

 I think it’s a injector or fuel pump issue (maybe over – fuelling?). I guess that I need to get the fuel system tested by a mechanic with all the tech gear? Thanks Clark.

Thanks Philip. I was planning on doing these myself. This might change. Pressure testing would be a good idea too I guess. I see that you have the same engines as me. I have a question for you if you wouldn’t mind. I’ve been scoping out the job and the main heat exchanger with the integrated header tank has me wondering how much stuff has to be removed to get the cooler bundle out. The alternator and it’s mounts are in the way forward and the exhaust is in the way aft, so the bundle will not slide out to fully service this component without a lot of removing of kit. Is it possible to just remove the end caps and service it adequately that way? Looking at both of mine, the paint looks brand new, so I reckon that these have never been serviced in 10 years.The other coolers were done in the workshop 4 years ago, according to receipts.

Thanks Tony. I’m still researching this job before I tackle it. Re; the oil and fuel coolers on the QSC8.3, I can’t figure out how they would be serviced as there are no end caps. Could you please comment on how these are serviced?

Thanks Donald, I will just leave the engine mounts alone. That’s good advice wit( the cooling system. However, I still can’t figure out how to service the oil and fuel coolers. There are no end caps for access.
