sevencow Mercruiser Lower Shift Cable Kit for Alpha One Gen I & II and MC/MR/R 1978-Newer — Complete Stern Drive Replacement Kit

sevencow Lower Shift Cable Kit replaces worn Mercruiser lower shift cables for Alpha One Gen I & II, MC-I, MR and R-series stern drives (fits Mercury 865436A02 and related part numbers).

This complete lower shift cable kit from sevencow is built to restore reliable gear selection on a wide range of Mercruiser sterndrives from 1978 to newer. The kit includes the cable and all necessary fittings so you can swap out a damaged or corroded assembly without hunting down individual parts. Materials combine rubber, steel, copper and plastic components treated for rust resistance and long service life in marine environments.

Which Mercruiser models and years does this kit fit?

The sevencow lower shift cable kit is designed to match factory routing and connections for multiple Alpha One and MC/MR variants. It covers the most common Gen I and Gen II Alpha One sterndrives and earlier MC-I/MR/R models, simplifying replacement on many boats.

• Alpha One Gen I: 1983–1990
• Alpha One Gen II: 1991–2016
• MC-I, MR, R-MR: 1978 and newer
• Direct cross-replaces Mercury 865436A02, 19543A10, 19543A8 and several aftermarket equivalents

What exactly is included and how complete is the kit?

This package contains the lower shift cable plus every small part needed to install it at the stern drive end. Instead of sourcing anchors, guides and set screws separately, you get a matched set of components intended to reproduce OEM performance and alignment.

• 1 x lower shift cable (Part #41951A1)
• 1 x slide (33981T1), guide (43433) and anchor (43436)
• Set screws (10-31700, 10-20518), insert (14705), wrapping (38473) and stainless wire (21464)
• All parts are sized to replace Mercury and popular aftermarket part numbers

How durable is the sevencow shift cable in real-world boating conditions?

The kit uses corrosion-resistant steel and treated components with rubber and plastic seals to resist saltwater exposure and freezing temperatures. While no cable is maintenance-free, these materials and the included stainless wire are chosen to extend service life and reduce corrosion-related failures.

• Steel and copper conductors with rust-resistant finish
• Rubber and plastic housings to block moisture intrusion
• Designed for operation in adverse weather and below-freezing conditions

How straightforward is installation for a DIY or marine mechanic?

Installation is intended to be a direct replacement using existing routing at the stern drive. The included hardware matches common factory attachment points so a competent DIYer with basic tools can complete the swap, though reference to a service manual or a mechanic is recommended for unfamiliar installations.

• Direct-fit parts mirror original cable end fittings and mounting points
• Includes small components so no additional parts are required in most cases
• Recommended tools: basic hand tools, lubricant, marine grease and alignment checks

Who this is for: This sevencow lower shift cable kit is aimed at boat owners, independent marine mechanics and service shops working on Mercruiser Alpha One and MC/MR sterndrives that need a full lower cable replacement. It’s especially useful when the existing cable shows wear, binding, visible corrosion, or when you prefer replacing the complete terminal assembly rather than piecing together individual parts. If you maintain older Mercruiser sterndrives and want a single, cross-referenced kit to restore shift action, this unit supplies the core components and hardware to get the job done.
