Engine manufacturer's consumption charts are relatively meaningless for fuel burn as consumption can vary hugely for a given RPM based on load. My engine burns less than half of the manufacturer's projected fuel consumption at 7 knots / 1500 RPM. Repowering from 450 HP to 135 HP about halfed my fuel consumption, but then I only need 40 HP to go 7 knots.
