The Mercury 84-879171T21 Extension Cable gives you a little more room to work with—just over three feet—which is often exactly what you need to get the antenna into clean sky. It’s made for boats running the 8M0024918 GPS Kit and carrying a CAN P signal, especially setups without an Auto Pilot module in the loop. Once it’s in, the system simply carries on as if the extra length had always been there.\u003c\/p\u003e\n\u003chr data-start=\"601\" data-end=\"604\"\u003e\n\u003cp data-start=\"606\" data-end=\"622\"\u003e\u003cstrong data-start=\"606\" data-end=\"622\"\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"626\" data-end=\"713\"\u003e\n\u003cstrong data-start=\"626\" data-end=\"650\"\u003e3.2-Foot Extension –\u003c\/strong\u003e Adds a short, practical length of cable for cleaner routing.\u003c\/li\u003e\n\u003cli data-start=\"716\" data-end=\"802\"\u003e\n\u003cstrong data-start=\"716\" data-end=\"738\"\u003eCAN P GPS Signal –\u003c\/strong\u003e Passes the dedicated GPS line used on non-Auto Pilot systems.\u003c\/li\u003e\n\u003cli data-start=\"805\" data-end=\"871\"\u003e\n\u003cstrong data-start=\"805\" data-end=\"824\"\u003eGPS Kit Match –\u003c\/strong\u003e Intended for use with the 8M0024918 GPS Kit.\u003c\/li\u003e\n\u003cli data-start=\"874\" data-end=\"953\"\u003e\n\u003cstrong data-start=\"874\" data-end=\"898\"\u003ePlug-In Connectors –\u003c\/strong\u003e Uses factory ends for a direct, no-guesswork hookup.\u003c\/li\u003e\n\u003cli data-start=\"956\" data-end=\"1033\"\u003e\n\u003cstrong data-start=\"956\" data-end=\"978\"\u003eStable Data Path –\u003c\/strong\u003e Keeps the GPS feed steady across the added distance.\u003c\/li\u003e\n\u003cli data-start=\"1036\" data-end=\"1126\"\u003e\n\u003cstrong data-start=\"1036\" data-end=\"1062\"\u003eFlexible Cable Build –\u003c\/strong\u003e Easy to route through tight paths or narrow rigging channels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1128\" data-end=\"1131\"\u003e\n\u003cp data-start=\"1133\" data-end=\"1150\"\u003e\u003cstrong data-start=\"1133\" data-end=\"1150\"\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"1154\" data-end=\"1173\"\u003eGPS Kit 8M0024918\u003c\/li\u003e\n\u003cli data-start=\"1176\" data-end=\"1195\"\u003eCAN P GPS systems\u003c\/li\u003e\n\u003cli data-start=\"1198\" data-end=\"1232\"\u003eBoats without Auto Pilot modules\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1234\" data-end=\"1237\"\u003e\n\u003cp data-start=\"1239\" data-end=\"1275\"\u003e\u003cstrong data-start=\"1239\" data-end=\"1275\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1277\" data-end=\"1653\"\u003eThis cable gives you a little freedom when the factory harness comes up short. It lets you route the antenna to a cleaner mounting point—often up on the console or near the hardtop—without pulling the system tight or forcing awkward bends. The signal stays clean, and the GPS data remains steady. It’s a simple fix that solves a common rigging issue without creating new ones.\u003c\/p\u003e\n\u003chr data-start=\"1655\" data-end=\"1658\"\u003e\n\u003cp data-start=\"1660\" data-end=\"1675\"\u003e\u003cstrong data-start=\"1660\" data-end=\"1675\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1677\" data-end=\"2025\"\u003eGPS wiring is sensitive to poor shielding and loose connectors, and Mercury’s cable avoids both problems. The factory ends lock in securely, and the cable carries the CAN P signal without introducing noise or dropouts. Aftermarket extensions often struggle with consistency over time, but the OEM piece keeps things predictable season after season.\u003c\/p\u003e\n\u003chr data-start=\"2027\" data-end=\"2030\"\u003e\n\u003cp data-start=\"2032\" data-end=\"2039\"\u003e\u003cstrong data-start=\"2032\" data-end=\"2039\"\u003eFAQ\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2041\" data-end=\"2207\"\u003e\u003cstrong data-start=\"2041\" data-end=\"2089\"\u003eQ1: How can I tell if I need this extension?\u003c\/strong\u003e\u003cbr data-start=\"2089\" data-end=\"2092\"\u003eIf the GPS antenna won’t reach an open, clean mounting spot with the standard cable, this extension fills that gap.\u003c\/p\u003e\n\u003cp data-start=\"2209\" data-end=\"2334\"\u003e\u003cstrong data-start=\"2209\" data-end=\"2260\"\u003eQ2: Does adding this cable weaken the GPS feed?\u003c\/strong\u003e\u003cbr data-start=\"2260\" data-end=\"2263\"\u003eNo. The cable is built for stable CAN P communication over this length.\u003c\/p\u003e\n\u003cp data-start=\"2336\" data-end=\"2460\"\u003e\u003cstrong data-start=\"2336\" data-end=\"2386\"\u003eQ3: Can this be used on boats with Auto Pilot?\u003c\/strong\u003e\u003cbr data-start=\"2386\" data-end=\"2389\"\u003eIt’s meant for systems \u003cem data-start=\"2412\" data-end=\"2421\"\u003ewithout\u003c\/em\u003e an Auto Pilot module in the GPS chain.\u003c\/p\u003e\n\u003cp data-start=\"2462\" data-end=\"2589\"\u003e\u003cstrong data-start=\"2462\" data-end=\"2504\"\u003eQ4: Will it fit narrow rigging routes?\u003c\/strong\u003e\u003cbr data-start=\"2504\" data-end=\"2507\"\u003eYes.
