Mercury – Speedometer 65 MPH | Boat Speed Monitoring | Black Face | Black Bezel | 79-8M6020028

This 65-MPH speedometer gives you a steady, no-drama read on how the boat’s moving. The needle reacts in a quiet, predictable way when you push the throttle or back off in rougher water.

Performance & Practical Benefits
On the water, the gauge feels calm and easy to glance at, even when the boat’s moving around a bit. The wider speed range gives faster hulls room to show real numbers without crowding the dial. The needle doesn’t flutter when you trim out or run into small chop, which makes pacing the boat feel more natural. It simply gives you a clean sense of how fast you’re running without pulling your focus away from the water.

Why Buy OEM
OEM gauges stay consistent because they communicate cleanly with Mercury systems. They tend to hold their accuracy longer and deal with real-world vibration and weather better than cheaper replacements. It’s the kind of reliability you appreciate when you’re out often.

FAQ
1. What signs point to a failing speedometer?
If the needle hesitates, drops out, or gives odd numbers at steady throttle, it’s usually wearing out.

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

3. How does it handle saltwater?
A quick rinse after each outing keeps it in good shape, and it handles marine conditions well.

4. Anything to watch for during installation?
Clean, snug signal and power connections help the needle stay smooth on the water.

5. What does a worn gauge usually do?
You’ll see slow response, drifting readings, or random drops to zero.
