We have a 2000 270 Sundancer powered by a single MerCruiser V8 7.4 MPI with Bravo 3 outdrive. Only had her since late Oct. of this year, so we are still getting to know each other. I find that about 3400 RPM seems to be her sweet spot for fast cruising. My wife wants to cruise slower to enjoy the ride and conserve fuel. What are your opinions on speed? What do others "slow" cruise at? I will add that I have always had runabouts and this is my first "big" boat. I've been told by a mechanic that I drive her like a ski boat. Meaning that I get on the throttle and I do tend to take fast turns, something I am working on correcting. I understand that depending on the weight in the boat will affect mileage, as will the tank levels etc. I'm looking for what speed folks cruise at for a leisurely ride. We are on the California Delta so its a lot of channels and sloughs, so a lot of water that's not wide open.
