Mercury – Block Water Pressure Sensor Kit | SmartCraft Data Integration | Marine Electronics | 8M0142696

Overview

When you spend enough days on the water, you learn to trust the quiet signals your engine gives you. A smooth idle, a steady temperature, that familiar hum when you throttle up—those little cues are what let you relax and enjoy the ride. Adding accurate water pressure data to your SmartCraft display gives you one more layer of confidence, especially when you are running hard offshore or navigating skinny water near home. The Quicksilver 8M0142696 Block Water Pressure Sensor Kit brings that peace of mind into clear view, turning raw engine behavior into useful, real-time information you can trust.

Performance & Practical Benefits

Once installed, this water pressure sensor does more than just send numbers to a screen—it gives you a clearer picture of what is happening inside your engine. You will feel the difference in how confidently you run the boat, especially when you are trimming high, cruising shallow flats, or pushing into choppy water. A steady pressure reading tells you everything is flowing the way it should. A sudden dip alerts you early, long before you feel a temperature spike.

The sensor seats securely, with a clean, tight fit that feels like it was built into the engine from day one. The digital feedback through SmartCraft instruments is smooth and responsive, giving you real-time data without lag. Whether you are idling into the marina or making a long run across open water, that steady flow of information becomes part of your routine—simple, reliable, always there when you glance at the helm display.

And because the kit is engineered specifically for Mercury and Mercury Racing outboards, durability is not a concern. It stands up to heat, vibration, and the constant moisture of marine life without drifting out of calibration.

Why Buy OEM

You can find aftermarket sensors out there, but compatibility and reliability vary wildly. With a genuine Mercury Marine part, you know the sensor communicates properly with SmartCraft, fits the engine block correctly, and maintains accuracy over time. OEM quality means fewer headaches, fewer false readings, and a system that works exactly the way the engineers intended. If you rely on your engine—truly rely on it—OEM is the only choice that makes sense.
