    2000 Johnson 150, Model # RJ150PLSSC, Serial # G04842007

    I only run XD-50 in this motor. I pulled the prop off to send to Mark to be worked and noticed that the inside of the prop and everything that had to come off to pull the prop was really black and sooty. What could be causing this and could it be something to be concerned about?

    What o your spark plugs look like? Running XD50 it is recommended to do an annual de-carb. I ran XD100 exclusively in my 2004 Johnson and never had carbon build up.
