Mercury – Block Water Pressure Digital Kit | SmartCraft Pressure Input | 8M0089111

Overview

Keeping an eye on cooling performance is a lot easier when your SmartCraft display shows block water pressure in real time. The Mercury 8M0089111 Block Water Pressure Digital Kit gives 2.1L F75–115 FourStroke engines the ability to send that pressure data directly into the SmartCraft network. It’s a clean way to add an important piece of engine information without guesswork or extra steps at the helm.

Key Features

• Digital Pressure Reporting – Sends block water-pressure data straight to SmartCraft gauges and displays.
• 2.1L FourStroke Ready – Built specifically for F75, F90, and F115 2.1L engines.
• SmartCraft Integration – Provides a stable digital signal recognized immediately by compatible instrumentation.
• Cooling System Insight – Helps the operator spot pressure changes early, especially in shallow or high-trim running.
• OEM Plug-In Fit – Installs cleanly with factory connectors and proper SmartCraft wiring.
• Reliable Data Feed – Offers steady readings so the helm reflects true engine conditions.

Compatibility

• Mercury 2.1L F75 FourStroke
• Mercury 2.1L F90 FourStroke
• Mercury 2.1L F115 FourStroke
• SmartCraft gauges and VesselView displays

Performance & Practical Benefits

This kit brings real-time block water-pressure data to the dash, giving you a clearer picture of how the cooling system is behaving. It’s especially helpful when running shallow, trimming up high, or pushing the engine hard for long stretches. With the digital sensor feeding SmartCraft directly, the readings stay steady and easy to read, making the whole setup feel more confident and responsive.

Why Buy OEM

Block water-pressure monitoring relies on accurate calibration and clean digital communication. Mercury’s OEM kit uses the correct sensor values and factory connectors so the SmartCraft network reads the pressure exactly as it should. Off-brand sensors often introduce erratic numbers or fail early, but the OEM version stays consistent through real-world heat, vibration, and saltwater use.

FAQ

Q1: When do I need this digital pressure kit?
When running a 2.1L F75–115 engine and you want block water-pressure readings to appear on SmartCraft gauges or VesselView.

Q2: Does this change how the engine cools?
No. It only provides monitoring—it doesn’t alter cooling performance.

Q3: Will the SmartCraft display recognize it automatically?
In most cases, yes. Once connected, the display picks up the signal with minimal setup.

Q4: Is installation complicated?
Usually not. It uses OEM connectors and mounts like other Mercury sensors.

Q5: Can it help diagnose cooling issues?
Yes. Steady or dropping pressure readings can help identify potential cooling restrictions earlier.
