sd,
I had the Mercury 454 Horizon with fuel injection. One of the best pieces of machinery it has been my pleasure to own. I found the "sweet spot" at about 3400 RPM and we could (and did) cruise for hours at about 20 - 21 knots. I was using a three bladed prop 18 x 21 with a slight cup. We acheived an average of 7.4 gallons per hour over the course of any given season.
The Chesapeake is on my list of cruising destinations one day. Looks like a very interesting shore line with places to stop and explore.
