(01-09-2019, 08:56 AM)jav1 I agree with atypicalguy. Marinized engines usually get modifications to deal with the differences of load duty cycles versus on road counterparts. At anything over hull speed, the loads are much higher on the engine and EGT monitoring is especially important. I suspect your EGT's, without the turbo providing additional air were extreme. What type exhaust system did you use? Was it a wet or dry exhaust manifold? Was the Turbo water cooled? Did you use a wet exhaust and did you check exhaust back pressure? Volvo has a very good marine diesel installation manual. I may have it in PDF if it's of interest?
Was there much smoke during those 100 hours? I'd closely inspect the pistons, head and likely replace the valves/seats just to be safe. I'd also mount an EGT gauge straight away when you get it running again.
The exhaust manifold that I have made is a wet manifold, the turbo is just heat isolated after the turbo the exhaust pipe goes up and then turn 180 degree down after that I mix the sea water from the manifold with the exhaust.
the sea water has first went true the intercooler and the heat exchanger and finally the exhaust manifold
I have not checked the back pressure I can check it between the turbo and where I mix in the water because there the exhaust is dry.
If you can find the PDF from Volvo it would be of big interest.
If I gave it full trotle there came black smoke but as long as I kept it at max 2500 rpm it was fine.
I will mount a gauge for the EGT
