Hello,
I have SedRay 340DA with twins Mercuisers 7.4 MPI 1999
Oil is about 1 year old. Oil levels are fine. Oil looks clean, not darkened, no particles. In both engines.
I also noticed that starboard engine consume more fuel than portboard engine, on RPM 3000 and above
Two quesitons:
1 when running above 3000RPM I obtain some amount of exhaust smoke. Is that normal? (I have a lot more pictures and videos if needed)
2 Oil pressure gauge readings on two engines are different: Port board stay still at 40PSI, while starboard is ~~30 PSI
and yesterday after running at 4000RPM I noticed it drops to ~~25PSI.
So the question is is that normal? what may cause it and where I should start and how to process with research?
