You may have read thru my other thread http://www.clubsearay.com/index.php?threads/calling-all-8-1-gurus-running-rich.87838/ where I was under the impression that poor spark may be the cause of my engine running rich showing petroleum product spotting in the exhaust. I say petroleum product because I'm not 100% sure it is gasoline, I'm like 85% sure it's gasoline.
Well, the plugs and wires have now been swapped and it's still doing it. (Even after running for five hours over the weekend, so I know the residuals should have been flushed out of the exhaust.)
No water in Engine or transmission oils, antifreeze level is unchanged.
I'm also following a thread on "SeaRay Owners" page on Facebook where another person is having this same issue and two more folks indicating similar issues, so it seems not crazy uncommon.
By the way, I have cool fuel II, so it's most like not a cool fuel paint issue.
Next steps (in my mind):
1. Check fuel pressure as recommended by Scoflaw.
2. Send of injectors for cleaning / flow testing.
Questions to you folks, What else could it be? Any "next steps" that you would add to my list above?
Thanks for reading.
