Sierra Lower Shift Cable Kit 18-2600 for MerCruiser #1R, MR, Alpha, Alpha I, Gen II and Bravo Drives, Package of 25

The Sierra 18-2600 Lower Shift Cable Kit is a bulk-packaged repair kit built for MerCruiser #1R, MR, Alpha, Alpha I, Gen II and Bravo stern drives. Each package contains 25 complete kits, making it suited for marine service shops and dealers who need to keep lower shift cable repair parts in stock rather than ordering one job at a time. Each individual kit inside the package bundles the four components needed to service the lower shift cable connection at the stern drive: a shift cable bellows to seal the cable where it passes through the drive housing, a shift cable assembly, a shift slide and screw, and a shift cable end kit. Supplying these parts together lets a technician complete a full lower shift cable service in one pass instead of sourcing each piece separately. The shift cable bellows, shift cable assembly, and shift slide and screw each carry a stated OEM cross-reference number, so the kit can be matched directly against the equivalent Mercury Marine part numbers during a repair. Because the kit covers #1R, MR, Alpha, Alpha I, Gen II and Bravo drives, it applies across several generations of MerCruiser stern drive shift linkage.
