Boat would start, would idle for awhile then run itself out of gas, after many months and many parts(shop covered cost of parts). A bad ECU(the brain of the motor) was at fault (expensive item!). Boat now runs like brand new. Was told that these rarely go bad, and that it couldn't be the problem, and this was the first one that this boat shop(reputable shop) ever had to replace. Has any one ever had to deal with Merc/Mariner to get some sort of compensation. Or would I be beating my head against the wall.
