Mercury – Tachometer Gauge 7K | Engine Speed Monitoring | White Face | Black Bezel | 79-8M6020050

Overview
This 7,000-RPM tachometer gives you a clean, steady read on how the engine’s running without jumping around every time the boat leans or hits a wave. The needle has a smooth, relaxed sweep, so grabbing your RPMs feels quick and natural. Out on the water, it settles in fast—no fuss, no guessing, just a straight read that matches what the engine’s actually doing. It’s the kind of gauge you stop noticing because it works the same every trip.

Performance & Practical Benefits
Out on the water, the extra RPM range makes it easier to see where the engine feels happiest, especially when you’re trimming out or running a little harder. The reading stays stable instead of fluttering, which helps you settle into a smooth pace. It’s easy to check without breaking your focus, whether you’re cruising a shoreline or running wide water. It just gives you a steady sense of how the engine’s working.

Why Buy OEM
OEM gauges follow Mercury’s sensor signals closely, so the readings stay accurate instead of drifting over time. They handle heat, weather, and vibration better than cheaper options. Most boaters stick with OEM because it keeps things simple and dependable.

FAQ
1. How do I know if the tachometer is starting to fail?
If the needle hesitates, sticks, or shows numbers that don’t line up with engine sound, it’s probably fading.

2. Does this gauge need calibration?
Most setups read correctly right away, but giving the settings a quick check during install is smart.

3. How does it handle saltwater?
A rinse after your run keeps it working well through long saltwater seasons.

4. Anything important during installation?
Clean grounds and tight signal wiring help the needle stay smooth and honest.

5. What does bad behavior usually look like?
You’ll see drifting RPM, dead spots on the sweep, or occasional jumps for no reason.
