I have a 1985 E32-III with a Universal M25 Diesel & a feathering Maxprop. Last year I replaced the "riser" and all of the hoses exiting the manifold. This year I am noticing that when I put her in reverse...I notice black soot on the water after backing down? I have tried running it hard in reverse for several minutes but it doesn't seem to clear up...just more soot? There is no noticable smoke or anything...just soot on the water? Anybody have any ideas what might be causing this?
