I am a boat owner but not a cruiser like a 280 sea ray that I am looking at. I live on a river that connects to the Mississippi river and if I could find the right boat my wife and I could have unlimited travel options. The only problem is fuel is hard to get on the river and I need about a 200 mile range. What is the range of the 280 with a single 496 mag mpi setup. If that is not the ticket which model and setup would come closer to meeting my needs?
