Sierra 18-2145 Shift Cable for Mercruiser #1 Drives (S/N 1562900-6225576), Forward Installation, Replaces 815471A3, 43432A2

The Sierra 18-2145 is a shift cable engineered for Mercruiser #1 Drives within the S/N range 1562900-6225576, designed for forward installation into the bell housing. It uses new style armored strand construction with no support tube, paired with a 54 inch conduit, so the cable transmits shift input from the control station to the drive with a durable, flexible core built for the marine environment.

The cable ships with a complete hardware package, including a Sierra 18-0318 washer and a 0.375-24 nut, so the installation has the fasteners needed to complete the job without sourcing them separately. Its alloy steel construction and white finish are built to hold up under repeated shifting and outdoor marine exposure. Overall product dimensions are 19 inches L x 14 inches W, and the unit weighs 1.2 pounds.

This shift cable directly replaces a range of original equipment part numbers, making it a straightforward swap for boats using the applicable Mercruiser #1 Drive within the stated serial number range. Confirm the drive's serial number falls within 1562900-6225576 and that the installation is a forward bell housing configuration before ordering.
