Thought I would start my own since this has gotten worse. I just wrapped up a ~460nm trip from Seattle to Canada and back. I've had a soot issue since I got the boat, but after my return trip yesterday, about 80 miles, the port motor has gotten considerably worse. Attached are 2 pics from after I returned to the dock, previously both motors sooted the transom at about the same rate, and most of this trip that was the case, so I was a bit (OK, a lot) shocked when I saw this on the port side.
Based on input from various threads here, I've:
At this point, I'm wondering if my next step is the injectors, do they need to be cleaned/adjusted/tested? The port motor does use about 1/8 of a tank more than starboard over the course of a tank, so I'm pretty sure the sooting is unburned fuel?
Thanks in advance, hopefully I can get this sorted out this fall.

Based on input from various threads here, I've:
- Changed to CAT SAEO oil
- Removed and cleaned/pressure tested the aftercoolers
- Removed all bits of impeller/other bits from the heat exchangers and then flushed the cooling system with RidLyme (mostly to help solve a temp increase and white steam from the port motor)
- Did the fuel system shock treatment from Franks' awesome Fuel Management post
- Cleaned and oiled the Walker AirSeps
