Mercury – Water Temperature Gauge C–H (60–200°F) | Cooling System Monitoring | White Face | Brushed Bezel | 79-8M6020071

Overview
This 60–200°F water-temperature gauge gives you a calm, steady read on how warm the engine’s running. The needle doesn’t flutter when the boat rocks—it eases into place, making small changes easy to spot. Out on the water, it’s the kind of gauge you check without thinking: one quick look, and you know if things are running as they should. Simple, predictable, and helpful on any outing.

Performance & Practical Benefits
On the water, this gauge helps you catch rising temps early, especially when running shallow, dealing with weeds, or working the engine hard on a warm day. The steady sweep makes real changes obvious without being overly sensitive. It’s quick to read mid-cruise or when easing into a channel. Over time, it becomes a quiet part of keeping the engine in its comfort zone.

Why Buy OEM
OEM gauges read Mercury’s sender signals the way they’re meant to, so the temperature you see is the truth. They hang in there through heat, weather, and vibration better than cheaper alternatives. Most boaters stay with OEM because it keeps the information reliable year after year.

FAQ
1. How do I know if the temperature gauge is failing?
If the needle stays stuck, jumps around, or barely moves as the engine warms up, it’s likely wearing out.

2. Does this gauge need calibration?
Most rigs read correctly right away, but checking the sender connection during install is always smart.

3. How does it handle saltwater?
With a quick rinse after your run, it holds up well through saltwater seasons.

4. Anything important during installation?
Clean wiring and a solid ground help the needle move smoothly and keep the reading accurate.

5. What does overheating look like on this gauge?
The needle climbs toward the upper section and doesn’t settle back down under load.
