Sierra Shift Cable Assembly 18-2157, Replaces 19543A2, for Mercruiser #1 Drive Forward Installation

The Sierra 18-2157 is a shift cable assembly built for Mercruiser #1 Drives within the serial number range 1562900-6225576, configured for forward installation into the bell housing. It uses an old style stranded core wire with a soldered tip, a design carried over from the original equipment configuration on these drive units, and it is paired with a 63 inch conduit to route the cable from the control station to the drive.

Because this cable is built for forward installation into the bell housing, it requires Sierra support tube 18-2160, which is not included and must be ordered separately to complete the installation. Selecting the correct shift cable assembly matters for reliable shifting between forward, neutral, and reverse, and this assembly is a direct fit replacement for the OEM numbers listed below, so it drops into the same mounting points and connects to the same shift linkage as the original part.
