Since the Mercury 2 to 5 outboard engine is a high-performance model, its fuel consumption is relatively high. Its fuel consumption is affected by many factors, such as the driving mode, the size and weight of the ship, and the sailing speed. In general, the average fuel consumption of the aircraft is between 0.6 and 0.8 litres per hour, with specific values varying depending on water conditions and ship type. Therefore, users should be prepared for sufficient fuel before sailing to ensure a smooth and safe trip.
