Honda’s exclusive Lean Burn Control™ system automatically adjusts the air/fuel mix according to speed and load. This helps our motors to deliver best-in-class fuel efficiency in “cruise mode” from 3,000 to 4,500 rpm.
Traditional motor designs use a fixed air-fuel mixture that does ok at low and high speeds, but not in the mid-range.
Honda added an Oxygen Sensor, which monitors the air/fuel ratio and automatically adjusts it as needed.
At cruising speed, Honda engines run on up to 20% less fuel than other comparably sized outboards.
The result? More power when you need it, and greater fuel economy.
