Mercury – Platinum Plus Throttle and Shift Cable 20 Foot | Mechanical Engine Control - 858342A20

The Mercury Platinum Plus Throttle and Shift Cable is designed for Mercury mechanical control systems where smooth, dependable response is required over longer routing distances. Featuring Platinum Plus construction, this cable delivers a direct mechanical connection between the helm and engine while reducing internal friction to maintain steady, predictable throttle and shift movement. The 20-foot length supports extended console-to-engine layouts without compromising control feel.

This cable is intended for boat owners and marine technicians maintaining traditional Mercury mechanical throttle and shift systems who want consistent control performance without transitioning to electronic controls. OEM construction helps preserve proper cable travel, clean gear engagement, and reliable throttle response across the full operating range.

From a maintenance perspective, replacing worn or stiff control cables helps restore predictable operation while reducing strain on control boxes and engine linkages. Platinum Plus construction is engineered to minimize internal resistance and resist corrosion-related wear, supporting longer service life in demanding marine environments.

FAQs

1) What systems is this cable compatible with?
This cable is designed for Mercury mechanical throttle and shift control systems (non-DTS).

2) What advantage does Platinum Plus construction provide?
Platinum Plus cables reduce internal friction, providing lighter control effort, smoother operation, and reduced wear on control components.

3) When should this cable be replaced?
Replace the cable if throttle or shift movement becomes stiff, inconsistent, or binding is present.

4) Is this cable compatible with DTS systems?
No. This is a mechanical throttle and shift cable and is not compatible with DTS systems.

5) What should be checked after installation?
Confirm smooth cable routing and verify full throttle and shift travel before operating the engine.
