I have a 1984 model 4-108 that
I have a 1984 model 4-108 that has suddenly developed a problem with low power. The engine was running happily at 2800rpm (around 6.5knots in our yacht) and then suddenly it reduced speed to around 2400 revs and now that is the maximum speed it will do under load. It revs to over 3000 rpm in neutral and runs smoothly. The injectors and fuel injection pump (it had developed a leak) have since been rebuilt and the compression is good on all cylinders. Any suggestions - I am wondering if it is possible that the valve or fuel pump timing has somehow changed - is that a possibility?
Any bright ideas welcome!
