Mercury – Mechanical SmartTow Helm Kit | Speed & Tow Control Interface | 8M0101650

Overview

SmartTow brings a level of consistency and control that tow-sport boaters have wanted on mechanical MerCruiser engines for years. The Mercury 8M0101650 Mechanical SmartTow Helm Kit finally makes that possible. It delivers the same smooth pull-ups, steady speed control, and repeatable rider profiles once limited to Digital Throttle and Shift applications. With this helm kit installed, mechanical-control gas engines gain a modern, predictable towing experience that feels clean and intuitive at the wheel.

Key Features

• SmartTow Integration – Brings SmartTow and Cruise functionality to mechanical MerCruiser gas engines.
• Mechanical Control Compatibility – Designed specifically for engines using mechanical throttle and shift systems.
• Speed & Pull-Up Control – Enables preset acceleration profiles and consistent towing speeds.
• Gauge-Dependent Operation – Requires a Cruise/SmartTow-capable display or a Zero Off-capable gauge with token added.
• Single-Engine Design – Engineered exclusively for one-engine applications.
• Harness-Ready System – Requires engine-to-helm harness for proper installation and communication.

Engine & Boat Compatibility

• MerCruiser mechanical-throttle gas engine platforms
• Marine-specific MerCruiser engines supporting SmartTow and Cruise integration
• Systems using Cruise/SmartTow-capable gauges
• Systems using Zero Off-capable gauges with added security token

Performance & Practical Benefits

This helm kit gives mechanical-control boats the precision that tow sports demand. Pull-ups become smoother and more predictable, helping riders get on plane without sudden surges. Cruise and SmartTow profiles hold speed more steadily than manual throttle adjustments, especially in turns or choppy water. Once everything is connected, the helm feels more modern and responsive, and the driver can focus on line, traffic, and the rider instead of constantly chasing throttle position.

Why Buy OEM

SmartTow depends on clean communication between the engine, helm, and gauge. Mercury’s OEM kit is engineered specifically for these mechanical MerCruiser platforms, ensuring accurate throttle control and proper speed management. Aftermarket attempts often struggle with calibration or long-term reliability. The OEM kit installs cleanly, stays stable season after season, and delivers the consistency tow-sport drivers rely on.

FAQ

Q1: How do I know if my boat can use this helm kit?
If your MerCruiser gas engine uses mechanical throttle and shift and supports SmartTow/Cruise through a compatible gauge, this kit is designed for that setup.

Q2: Does this change the feel of the throttle while driving?
It maintains normal throttle feel, but SmartTow takes over during towing modes to hold acceleration and speed more consistently.

Q3: Is a special gauge required?
Yes. You need a Cruise/SmartTow-capable gauge or a Zero Off-capable gauge with the required security token.

Q4: Does it work for twin-engine boats?
No. This kit is for single-engine applications only.

Q5: Is installation complex?
Most installs require adding the engine-to-helm harness and connecting the helm unit. The setup is straightforward for anyone familiar with Mercury rigging.
