Removing the fuel rail doesn't look too bad. I just don't want to break any of the connectors. The entire engine and wiring harness is still covered in the original black paint from the Indmar...

Those are the last pictures and each time I replace them and wait 5-7 hours and then pull them they are worse. But, yes - the boat runs fine. Does not cough or sputter. Starts right away.

I guess it depends on one's definition of "slightly rich". I would classify them as being "Jeff Bezos" rich. Here are the latest pictures of some of the plugs I pulled over the weekend with only 5-7...

Are you referring to the pressure regulator on top of the fuel pump or the one on the fuel rail? Both have been replaced with the last 6 months. If either were bad, would that lead to plug fouling...
