I have a 26' formula 242ls that weighs in close to 5000lbs. With my previous 2 engines (476ci making 425hp and 509ci making 618hp) the fuel consumption was amazingly lower than many people thought. As stated above, mark your throttle where your primaries are open as far as they can before cracking the secondaries. That boat runs a bravo out drive instead of straight like the sc will. The key to fuel efficiency is propping it to perform well at cruise with the secondaries closed. That boat averaged 3.5-4mpg at cruise depending on the amount of people on board.
