Have a 2003 Carver 356 Aftcabin cruising on the Chesapeake and really love the boat. Great room and great quality. It's powered by two 8.1L Crusader gas engines. I've never seen a performance curve for the 356 with Crusaders equating RPM, fuel consumption, and speed as I have for other Carver models. Anyone seen such a graph? Had one for a 1988 Mariner '32 and it really helped in planning trips, best range RPM, and best economy RPM.
