Hi
Have recently lost power in one of my Cummins 6bta 315's.
I can now get no more than 1850 rpm and now blows black smoke, we should be able to get 2800.
Engine runs as it should up to 1850rpm, no smoke and runs smooth as silk.
Had the Cummins tech down for a look and he says engines are not the issue.
The boat is jet driven and he seems to think it must be the jet binding up.
Have checked jets and they are all clear and can turn shafts by hand.
Someone else has said it may be an Intercooler obstruction(air side).
Turbo and airfilter all good.
Any ideas ?
Thanks
