Morning all,
I am looking to step it up into a 310 Silverton Express Cruiser, 1999 with twin EFI 5.7l Merc's, boat currently has just under 400 hrs on the engines if that helps. I understand that speed, RPM and weight all play a role in fuel consumption, but with 6 adults on board, at the most optimal cruising speed - on plane (whatever speed that is) what kind of MPH can I expect to see from a boat of this size/style?
