Mercury – Gen I Throttle and Shift Cable 18 Foot | Mechanical Engine Control | 8M0085947

18-foot Gen I mechanical throttle and shift cable for Mercury control setups.

The Mercury Gen I Throttle and Shift Cable is a mechanical control cable designed for boats using traditional Mercury helm controls that require longer routing from the control box to the engine. Built for legacy Mercury Gen I mechanical control systems, it delivers a direct, no-frills connection that keeps throttle response and gear changes smooth, familiar, and predictable—especially helpful during docking, low-speed maneuvering, and everyday operation. The 18-foot length is well suited for longer console-to-engine runs where clean routing helps maintain consistent control feel.

Control cable condition plays a key role in throttle response and clean shifting. Routine inspection for stiffness, corrosion at end fittings, chafing along the run, and tight bends can help prevent binding and uneven feel. Replacing worn cables and maintaining proper routing supports reliable control operation over time.

Key Features

• Mechanical Control Design – Provides direct throttle and shift operation for natural helm feel

• 18-Foot Cable Length – Supports longer console-to-engine routing layouts

• Gen I Control Interface – Designed for legacy Mercury mechanical control systems

• Marine-Grade Construction – Built to withstand vibration, moisture, and everyday marine exposure

Engine & Boat Compatibility

• Mercury outboards

• Mechanical Generation I (Gen I) control systems

• Non-electronic throttle and shift configurations

Compatible with legacy Mercury control installations requiring an 18-foot Gen I throttle and shift cable.

Important Notes

• Control cable requirements vary by control generation and rigging layout.

• Confirm Gen I mechanical control compatibility and correct cable length before ordering.

• Proper routing—avoiding sharp bends, pinch points, and heat sources—and correct adjustment are required for smooth operation and safe shifting.

FAQs

1) What control systems does this cable work with?
It is designed for Mercury Generation I (Gen I) mechanical throttle and shift control systems.

2) What length is this cable?
This cable is 18 feet long, ideal for longer console-to-engine routing applications.

3) Are Gen I throttle and shift cables wear items?
Yes. Jackets, liners, and routing stress can affect performance over time. Routine inspection and replacement help maintain smooth control feel.

4) Why use an OEM Mercury Gen I control cable instead of an aftermarket cable?
Mercury OEM cables are built to original specifications for cable travel, fit, and durability, helping maintain proper control geometry and consistent throttle and shift response.

5) What should be checked during installation?
Verify correct routing, avoid sharp bends or heat exposure, secure the cable properly, and confirm full throttle and shift travel before operation.
