Performance & Practical Benefits
On the water, the gauge helps you settle into a comfortable pace without second-guessing the reading. The steady sweep makes small changes easy to spot, whether you’re trimming the bow, towing, or cruising a shoreline. It reads true even when the boat moves around, which makes the speed feel more predictable. It’s one of those quiet tools that keeps the day running smoothly.

Why Buy OEM
OEM gauges follow Mercury’s signal patterns closely, so the numbers stay accurate instead of drifting. They hold up well to real-world vibration, heat, and weather, which keeps the reading trustworthy season after season. Most boaters stick with OEM because it cuts down on guesswork.

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

4. Anything important during installation?
