This is the first boat I have owned that is efi. I know some engines are capable of interfacing to monitor fuel mileage. I installed GFS sensor on my other boats to determine my gph. Does this engine have any sort of fuel flow monitoring built in??

Hi there, yes if you had a Mercruiser smartcraft monitor, the PCM is designed to give a fuel consumption reading (GPH) based on monitored engine load.

Accuracy is supposed to be within 4% but I have read some reports that are as high as 11%.
