Mercury – Trim Analog-to-Digital and Limit Kit | SmartCraft Conversion | 8M0118725

Overview

Analog trim systems work well, but when you upgrade to SmartCraft gauges, the signal needs to speak the same digital language. The Mercury Trim Analog-to-Digital and Limit Kit (8M0118725) handles that translation cleanly. It takes the analog trim position from the engine and turns it into the digital output your SmartCraft display expects. It also adds an upper-limit function, giving you control over the maximum tilt angle to prevent the engine from lifting into a position where it might contact the boat.

Once installed, the trim readings become smoother and more predictable, and the engine tilts up only as far as you want it to. It’s a simple, dependable upgrade for anyone bringing older analog systems into the SmartCraft world.

Key Features

• Analog-to-Digital Conversion – Translates the engine’s analog trim sender signal into a digital output for SmartCraft gauges.
• Adjustable Tilt Limit – Lets you set a maximum tilt-up position to prevent interference when raising the engine fully.
• SmartCraft Integration – Designed to work seamlessly with SmartCraft monitoring systems.
• Clean Installation – Mounts neatly with factory-style wiring and connectors.
• Stable Trim Output – Provides smooth, consistent trim readings without jumpiness or lag.
• Purpose-Built Design – Engineered specifically for the 2.1L F75–115 Four Stroke family.

Engine & Boat Compatibility

• Mercury 2.1L F75 Four Stroke
• Mercury 2.1L F90 Four Stroke
• Mercury 2.1L F115 Four Stroke

Performance & Practical Benefits

This kit brings older trim systems up to speed with modern digital displays. The trim reading becomes cleaner, more responsive, and easier to trust while running the boat. The adjustable limit feature adds a practical layer of protection, preventing the engine from tilting too high and bumping into a bracket, transom, or rigging component.

The wiring is short, direct, and protected, which keeps the installation simple and minimizes long-term maintenance. Once it’s in place, the system usually starts communicating right away, and most owners notice their trim gauge behavior improve immediately.

Why Buy OEM

Analog-to-digital conversion needs to be precise for SmartCraft to read correctly. The OEM kit matches Mercury’s voltage and signal behavior exactly, which keeps the readings accurate and stable. Aftermarket versions often drift or misreport trim position, leading to more frustration than progress.

With the Mercury kit, you get reliable communication, proper tilt-limit control, and a clean fit that matches the engine’s original wiring layout.

FAQ

Q1: What are the common signs that I need this kit?
If you upgraded to SmartCraft gauges and the trim reading does not follow the engine, the analog sender cannot communicate digitally without this module.

Q2: Does the tilt-limit feature change normal trim operation?
No. You still trim the engine normally. The limit only affects the final tilt-up height.

Q3: Will this interfere with digital displays already on the boat?
It does not conflict with existing digital systems. It simply provides a correct digital trim signal.

Q4: Do I need to adjust the limit after installation?
Most rigs benefit from fine-tuning the limit once to match the boat’s transom and hardware clearance.

Q5: Is the module protected against moisture?
Yes. The components and wiring are designed for long-term marine exposure when installed properly.
