Performance & Practical Benefits
Out on the water, this gauge helps you get a feel for what the engine’s doing without fighting the display. The sweep makes RPM changes easy to see, whether you’re easing up onto plane or trimming things out for a smoother ride. It reads cleanly even when the boat rocks a bit, giving you a reliable sense of how hard the engine is working. It becomes part of your routine without you noticing.

Why Buy OEM
OEM gauges follow Mercury’s signal pattern exactly, which keeps the RPMs accurate instead of drifting around. They hold up better to vibration, heat, and weather than cheaper copies. Most boaters stay with OEM because it saves them from guessing what’s real and what isn’t.

FAQ
1. How can I tell if the tachometer is going bad?
If the needle lags, sticks, or shows numbers that don’t match the sound of the engine, it’s likely 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 each trip keeps it working well through saltwater seasons.

4. Anything important during installation?
Clean grounds and snug signal wiring make a big difference in how smooth the sweep feels.

5. What does failing behavior usually look like?
Expect drifting RPM, slow reaction, or sudden jumps in the needle.
