Why Buy OEM
OEM gauges read Mercury’s sender signal the way it’s meant to be read, keeping the temperature accurate instead of drifting. They’re built to shrug off heat, weather, and vibration better than cheaper alternatives. Most boaters stick with OEM because it keeps engine monitoring simple and dependable.

FAQ

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

3. How does it handle saltwater?
A quick rinse after each run helps it hold up through saltwater seasons.

Clean grounds and tidy wiring keep the sweep smooth and the reading accurate.

5. What does overheating look like on this gauge?
The needle climbs toward the upper end and doesn’t settle back down when the engine is loaded.
