Overview

The Mercury Fuel Flow Gauge (79-8M0069416) helps you keep an eye on how much fuel your engine’s using in real time. It shows flow rate on a dual-scale face — both gallons and liters per hour — so it’s easy to read no matter what units you prefer. The white face stands out well in sunlight, and the gauge fits a standard 2-1/8" (52 mm) dash hole. It’s built tough for marine use and pairs perfectly with other Mercury SmartCraft gauges for a clean, uniform look.

Performance & Practical Benefits

This gauge makes it easy to know what your fuel system’s doing. You’ll see live readings that help you fine-tune your throttle and save fuel over long runs.

Why Buy OEM

Mercury builds its gauges for the same conditions its engines face — heat, salt, and vibration. OEM parts give you the right connection, clean signal, and the durability you need season after season. No guesswork, no fitment issues, just gear that works the way it should.
