Sierra 18-2248 Shift Cable Assembly, Replaces Mercruiser 73723A1, Fits #1 Drives IA/IB/IC EZ-Shift MC-I

The Sierra 18-2248 Shift Cable Assembly is a complete replacement shift cable built for Mercruiser #1 drives, serial number range 1562900-6225576, for forward installation into the bell housing. It is designed to fit IA/IB/IC, EZ-Shift, and MC-I drive units (1977 and older). This assembly uses new style armored strand construction with no support tube, giving the cable core added durability and resistance to kinking compared to older cable designs. The 54 inch conduit comes complete with a hardware package, so everything needed for a proper installation is included in one box. Made from a combination of nylon and polyvinyl chloride (PVC), the assembly is built to stand up to the marine environment while providing smooth, reliable shift engagement. This cable is a direct cross reference for several Mercruiser OEM part numbers, making it a straightforward swap for boat owners replacing a worn, sticking, or broken shift cable on a compatible #1 drive. Whether the original cable has stretched, seized, or simply reached the end of its service life, the 18-2248 restores proper shift feel and function without modification to the existing bell housing mount.
