Mercury Air/Fuel Ratio Gauge

Air/Fuel Ratio Gauge for Mercury

This air/fuel ratio gauge for your Mercury features a 7 color selectable digital LED display, displaying the ratio in both digital and analog.

This Mercury air/fuel ratio gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running with too rich of an air to fuel ratio can cause a loss of power, and running a lean air to fuel ratio can result in serious engine damage. This  gauge can alert you to whether you are running, lean, optimal or a rich air to fuel ratio on your Mercury.
