I have twind DF175s drinking off one fuel tank. My actual total burn is higher than what my SMIS gauge reports for total fuel used by 12% running both engines. Have not recalibrated before and according to the manual it appears now I have to run the motors independently after filling up and then recalibrate each separately?? Can you not recalibrate both outboard interfaces at the same time when the engines are used equally?
