Performance & Practical Benefits
On the water, the wider speed range feels right for boats that like a little more pace. The needle doesn’t flicker when you trim out or slide through light chop, so the reading stays honest. It’s easy to settle into a speed that feels right for the conditions because the number doesn’t wander. Over a long run, it’s one of those tools that helps the boat feel a bit more predictable.

Why Buy OEM
OEM gauges pair cleanly with Mercury’s systems, which keeps the signal steady and the reading accurate. They handle vibration and weather better than cheaper options, so the gauge stays reliable after real use. Most boaters stick with OEM simply because it saves headaches later.

FAQ
1. What are early signs the speedometer is wearing out?
A needle that sticks, hesitates, or drops out at random is usually the first clue.

2. Does this gauge need calibration?
Most setups read fine right away, but giving it a quick check during the install is smart.

3. How does it handle saltwater?
A rinse after your trip keeps it in good shape through full saltwater seasons.

4. Anything important during installation?
Good, clean signal and power connections make a noticeable difference in how steady the needle feels.

5. What does a failing gauge usually do?
You’ll see drifting readings, slow response, or sudden dips in speed for no reason.
