Why Buy OEM
OEM gauges follow Mercury’s sender signals the way they’re designed to, which keeps the reading accurate instead of drifting. They stand up well to vibration, temperature swings, and day-to-day wear. Most boaters stick with OEM because it keeps their information reliable season after season.

FAQ
1. How do I know if the oil-pressure gauge is failing?
If the needle sticks, jumps, or doesn’t react when you change throttle, it’s probably 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 hold up in saltwater?
A quick rinse after each run helps it stay reliable through saltwater seasons.

4. Anything important to check during installation?
Clean grounds and snug signal wiring make the reading steadier and more accurate.

5. What does low pressure usually look like underway?
The needle drops toward the low side and stays there, especially when the engine is under load.
