Hi I recently purchased 2x Cummins QSB 5.9 marine engines. i also purchased a inline 7 data link adapter. im completely new to it all. but im a fast learner and mechanically minded. i would like any info on the mercury smartcraft or as ive been finding out a lot of people call it smartcrap. so if anyone knows of a better solution im willing to give it a go. engines yet to be installed in my vessel. i want to learn more about them before i install them and want to have the best control/information for engines and gearbox. So Hi to you all. I hope someone can help.
