Have you considered something like a Merry Fisher 805?
They are more expensive but at least with the sort of boat you don't need to be going fast all the time as you do in a 25ft sports cruiser. This sort of boat only has two speeds, very slow or bloody fast and on the plane.
I have a 24 ft Larson with a 5.0 Volvo petrol, does about 8 gph at 20 knots with a clean bottom. Next boat to be a single engine semi displacement boat like the one mentioned above.
Oh i dont know. We cruise with a whole range of other boats and can manage with the slow ones (up to 6 knots) and the quicker ones (20-30 knots) with no problems. The speeds in the middle we never use as it is just a waste of fuel. At displacement speeds a diesel cruiser will be quite frugal as well.
