Hello all. I am looking at a Sea Pro SV1900 with a F115. The owner says he didn't like how light one of the plugs looked so he pulled the fuel rail and injectors and had the injectors ultrasonically cleaned.
Today we did a compression test on it - 170 to 175 psi in all cylinders, so that seemed good. One thing I noticed though was the bottom plug's porcelain was a light tan color but the top three plugs were all pretty much white. I'm sure that the only run time lately and since the injector cleaning has been at idle on muffs.
Hoping to take it out for a ride this week. Taking another look after a good run may tell more. I know it's harder to get color on a plug with pump gas these days and that lean is mean, but wonder if this is normal or something to be concerned about.
Thanks in advance. -Greg
