Mercury – Oil Pressure Gauge L–H | Engine Protection Monitoring | Black Face | Black Bezel | 79-8M6020036

Overview
This oil pressure gauge gives you a steady look at how the engine’s lubrication system is holding up while you’re running. The needle settles into a smooth sweep, so any drop or spike stands out right away without forcing you to stare at the panel. Out on the water, it reacts naturally as you throttle up, idle down, or run through chop. It’s a simple tool that quickly becomes part of your routine checks at the helm.

Key Features
    • L–H Pressure Scale – Shows overall oil pressure in a clean, easy range.
    • Calm Needle Movement – Holds steady even when the boat shifts or hits chop.
    • Standard Dash Fit – Installs cleanly in common panel openings.
    • Backlit Face – Stays readable during low-light mornings or dusk runs.
    • Marine-Ready Build – Handles vibration, spray, and long seasons on the water.

Engine & Boat Compatibility
    • FourStroke outboards
    • Verado series
    • Pro XS engines
    • SmartCraft systems

Performance & Practical Benefits
On the water, the gauge gives you a quick read on whether the engine’s oil system feels healthy. The steady needle makes it easy to catch pressure drops early—especially at idle, during long runs, or when you hit rougher conditions. It blends into your normal scans without pulling attention away from the run. It’s one of those quiet, confidence-boosting tools every boater appreciates.

Why Buy OEM
OEM gauges read cleanly because they’re matched to Mercury’s sensors and electrical setup. They hold calibration well and stand up to vibration, heat, and weather changes better than cheaper replacements. Most boaters stick with OEM so they can trust the reading every time they glance down.

FAQ
1. What are signs the oil pressure gauge is wearing out?
If the needle sticks, jumps, or never moves from one spot, it’s probably failing.

2. Does this gauge need calibration?
Most rigs read correctly right away, but checking wiring and sender connections is always a good idea.

3. How does it do in saltwater?
With a simple rinse after trips, it handles saltwater seasons well.

4. Anything to watch during installation?
A clean signal wire and good ground make the needle steadier and more accurate.

5. What does low oil pressure usually look like on the gauge?
The needle drops toward the lower end and tends to stay there under load.
