Performance & Practical Benefits
Out on the water, this gauge helps you settle into a smooth pace without second-guessing the reading. The stable sweep makes changes easy to notice, whether you’re easing onto plane or trimming out for a cleaner ride. It reads the same whether you’re cruising steady or working through a bit of chop. Over time, it becomes one of those quiet tools that keeps the boat feeling predictable.

Why Buy OEM
OEM gauges follow Mercury’s signal output exactly, so the RPM you see is the RPM the engine is actually turning. They handle vibration, heat, and weather better than bargain versions. Most boaters stick with OEM because it keeps the information trustworthy season after season.

FAQ
1. How do I know if the tachometer is wearing out?
If the needle sticks, drifts, or doesn’t match what the engine sounds like, it’s likely fading.

2. Does this gauge need calibration?
Most setups read correctly right away, but checking settings during install is always smart.

3. How does it handle saltwater?
A quick rinse after your run helps it last through saltwater use.

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

5. What does failing behavior usually look like?
You might see slow reaction, dead spots, or random jumps in RPM.
