Performance & Practical Benefits
On the water, this gauge helps you stay ahead of heat-related problems by giving you an honest, steady temperature read. Small changes show up clearly, which makes a difference when running shallow, dealing with weeds, or working the engine on a hot day. It’s easy to check without breaking your focus, and it quickly becomes part of your regular scan across the dash. It simply keeps you in tune with how the engine feels.

Why Buy OEM
OEM gauges follow Mercury’s sender signals accurately, so the number you see is the number you can trust. They hold up better to vibration, heat, and weather than bargain options. Most boaters prefer OEM because it keeps the information steady season after season.

FAQ
1. How do I know if the temperature gauge is starting to fail?
If the needle sticks, barely moves, or jumps around, the gauge is likely wearing out.

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

3. How does it handle saltwater?
A quick rinse after each run keeps it working well through full saltwater seasons.

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

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