I have a 1995 225 EFI Mercury that consumed a full tank of gas in less than 7 miles at 50mph.Shop mechanics said it was first a fuel regular problem, then a computer problem. There were no leaks or sheen on water. Boat has been in shop for 3 months waiting for a computer.When I ask, all I get is it's on back order over and over. Does this diagnosis sound correct and are computers for this motor so hard to find? The motor ran fine, I just watched the fuel guage go from full to empty trying to get back to the dock.<br />Boat is still in shop so no numbers handy.
