The kit is built around the Sierra 18-2190 shift cable and includes the gaskets and bellows needed to reseal the outdrive housing during the swap, so the job can be completed without sourcing extra parts separately. The shift cable itself is finished in black and constructed from a nylon and vinyl combination for corrosion resistance and durability in a marine environment.\u003c\/p\u003e\u003cp\u003eThis kit is designed as a direct interchange for the Mercruiser 19543T1, 19543T2, and 865436A03 shift cables, as well as GLM 21450 and Mallory 9-72100 equivalents, making it a straightforward like-for-like replacement when the original lower shift cable has worn out or failed. Sierra manufactures the kit to meet or exceed the specifications of the original equipment part it replaces. Because shift cable kits are fit-specific, confirm the part numbers on your existing cable and housing before ordering to ensure proper fit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-2603\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Lower Shift Cable Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.61 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Nylon, Vinyl\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Shift cable (18-2190), outdrive gasket (18-2619-1), outdrive mounting gasket (18-2743), shift cable bellows (18-2753-1)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999875136\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e GLM 21450, Mallory 9-72100, Mercruiser 19543T1, 19543T2, 865436A03\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFit specific;
