Changed the oil in both gearcases today on my BF200´s. Starboard oil was brand new and clear, I was really surprised, port oil was black, black, black. No abnormal findings on either chip detector. Have been searching the internet and the consensus is not to worry about black gearcase oil. Last change was also done by me, same oil in both units, same hours, etc. Both engines work fine, no abnormal noises, vibrations, etc. No traces of seawater mix (milky). Any idea why one oil is brand new and the other black? Should I be concerned? Thanks!
