Something else. Silver has been harping on this 10% thing at WOT for quite awhile. So, being of an inquisitive mind, I have been following fuel consumption data on numerous types of engines including marine, automotive, and heavy duty diesel. Can't say that I've found much over a 10% variance in economy, regardless of engine type. found that amazing. [links]
5500RPM, 27mph, 3.4gph, 7.9mpg
Other thing you point out here is what has been repeated many times: Best fuel economy is usually just on plane where the boat drag is smallest and engine is running in an economical part of the power band.

You should have gotten some paper work with it. It should have a model number that, combined with the serial number, can lead to the exact motor in the parts world. more
Re: Mercury outboard oil consumption question
Usually engines require additional oil during the first 10 hrs of breakin or so. Double the oil (25:1) is usually the case and you can do that by adding 1 pt oil to 6 gallons of gas which, when added to your normal VRO would give you your breakin mix. When you finish your 10 hrs, if you have fuel left, don't worry about it or fill up with plain gas to dilute the remaining oil

In addition to improved fuel efficiency and performance characteristics, the BF40 and BF50 EFI also incorporate a number of features designed to facilitate maintenance. An automotive-type oil filter and color-coded oil fill and dipstick simplify fluid level checks and changes. Additionally, both are compatible with Honda's HDS portable diagnostic system to facilitate on-water service. [links]
The engines' best-in-class 22-amp alternator (17 amps of battery charging), ignition, and other critical components are mounted near the top of the powerhead to ensure that all are kept cool and dry. By extension, a camshaft-driven, automotive-style oil pump ensures long-term durability of critical engine components. here
Redefining Four-Stroke Performance
The BF40 and BF50 EFI are available in 20- and 25-inch shaft models. MSRP for remote-controlled BF40 models is $7,136, while remote BF50 models will retail for $7,999. All new Honda outboard engines sold for recreational use offer an industry-best True 5-year, non-declining limited factory warranty that is the same on the last day as it is on the first.
Both feature Honda's exclusive double-sealed and multi-layered Four-Front Corrosion Protection (paint) System, as well as several other features designed to minimize damage caused by the harsh marine environment. A unique one-touch anode check system and improved waterproofing inside the engine cover and gear case are just a few of the innovative features Honda has added to ensure the motors' long-term durability.

There are plenty of good reasons these outboards rule the water. Start with no-worry reliability. More low-end torque for excellent acceleration. Increased fuel economy and outstanding overall performance. Enhanced fuel injection (EFI models) for boosted efficiency. A robust electrical system with a high-output alternator to keep batteries charged and fishing electronics humming. They have everything you need, and nothing you don’t. here
