Hey guys. Had the boat for about a year now. We’ve noticed the starboard engine has started to smoke quite a bit. While underway at 1600 it had a moderate amount of black smoke. Never used to. Port engine doesn’t smoke. If it wasn’t for the smoke, I’d never know anything was wrong.
We had friends following us to an anchorage and they said it was pretty much smoking the entire time, even in no wake zones.
I did have an overheat issue with that engine when we had a split coolant hose. It alarmed a couple of times at 200 degrees before I shut it down. I can’t imagine it ever got hot enough to hurt anything, although it is in the back of my mind.
Any thoughts?
I have a Cummins 5.9 in my F350 with bigger injectors and turbo. Black smoke is a sign of too much fuel and not enough air. So maybe this Lehman is having a turbo or intercooler issue?
