Mercury – Analog Block Water Pressure Sender | DTS Engine Add-On | 8M0145165

Overview

Digital engines offer a lot of information, but sometimes an old-school analog gauge is still the quickest way to keep an eye on cooling performance. The Mercury 8M0145165 Analog Block Water Pressure Sender gives DTS engines that option. It adds the analog water-pressure signal that mechanical engines already have, making it easy to run a traditional gauge at the helm without changing anything about how the engine operates.

Key Features

• Analog Pressure Output – Supplies a clean analog signal for a standard water-pressure gauge.
• Designed for DTS Engines – Intended for 3.4L V6 and 4.6L V8 DTS engines that lack the analog sensor.
• Factory Feature on Mechanical Models – Mechanical versions already include this sensor from the factory.
• Cooling Awareness – Lets the operator monitor block water pressure with a quick glance.
• OEM Plug-In Fit – Installs using Mercury’s factory connectors for a straightforward setup.
• Gauge Ready – Works with traditional analog water-pressure gauges used on many helm layouts.

Compatibility

• 3.4L V6 DTS Mercury outboards
• 4.6L V8 DTS Mercury outboards
• Analog water-pressure gauges
• SmartCraft-equipped DTS platforms wanting analog gauge output

Performance & Practical Benefits

This sender gives DTS engines the ability to run a classic water-pressure gauge—something many boaters still prefer for quick visual feedback. Analog gauges react instantly, making it easier to catch low-pressure situations when trimming the engine high or running in shallow water. With the sender installed, you get the same cooling awareness mechanical engines offer, but without altering the digital side of the system.

Why Buy OEM

Cooling-system sensors need to be accurate and durable, and Mercury’s OEM sender is calibrated specifically for these DTS engines. Aftermarket versions often drift or fail early, leading to misleading gauge readings. The factory sender fits correctly, communicates cleanly, and holds up in real marine environments.

FAQ

Q1: When is this analog sender needed?
When you want an analog water-pressure gauge on a DTS 3.4L V6 or 4.6L V8 engine.

Q2: Do mechanical engines need this kit?
No. Mechanical models already have the analog pressure sensor installed.

Q3: Does this replace the digital water-pressure data?
No. It simply adds an analog output for a traditional gauge.

Q4: Will installing this change engine behavior?
No. It only provides a signal for the gauge and does not affect engine operation.

Q5: Where will I see the pressure reading?
On the analog water-pressure gauge you connect to the sender.
