I've been running it on the muffs a few times to diagnose another issue and there's a thick black oily sludge coming thru the prop/exhaust.
So far, I've changed plugs, and plug wires, had the injectors cleaned and serviced, verified fuel pressure and verifed spark to all 6 cyls.
Smokes quite a bit too.
How concerned should I be about the sludge?
I want to take it out and run it but she's still running a little rough and I don't want to risk heading out on the water and causing damage if there's something else i should be checking.
