Mercury – Tachometer 7K | Engine Speed Monitoring | White Face | Chrome Bezel | 79-8M6020014

Overview
This 7,000-RPM tachometer gives you a steady feel for how the engine’s running, even when the boat moves through chop. The sweep is smooth and predictable, so you can grab your RPMs with a quick glance. Out on the water, the reading usually matches what you hear from the engine, which makes cruising or trimming out feel more natural. It’s a simple, clean-looking gauge that fits right into everyday use.

Performance & Practical Benefits
On the water, the wider RPM range helps you see where the engine feels best, especially on rigs that like a little more throttle. The steady sweep makes it easy to notice small changes without watching the gauge too long. It’s helpful during cruising, trimming, or easing around tight spots. Over time, it becomes a natural part of keeping the boat running smoothly.

Why Buy OEM
OEM gauges follow Mercury’s signal output exactly, so the reading stays accurate instead of wandering. They hold up well to vibration, weather, and day-to-day use. Most boaters stick with OEM because it keeps their information honest and predictable.

FAQ
1. How do I know if the tachometer is failing?
A needle that sticks, lags, or doesn’t match engine sound is a common sign.

2. Does this gauge need calibration?
Most boats read correctly right away, but checking settings during install is a good idea.

3. How does it hold up in saltwater?
A rinse after each run helps it last through saltwater seasons.

4. Anything important during installation?
Clean grounds and snug signal wiring keep the sweep smooth and reliable.

5. What does bad behavior usually look like?
You might see drifting RPM, slow movement, or jumpy readings.
