The Mercury 84-8M0054183 MP Alert Harness Extension gives you a clean, 10-foot extension to route an MP Alert light toward the front of the boat. It plugs directly into the existing MP Alert wiring and keeps the system’s warnings visible well beyond the transom.\u003c\/p\u003e\n\u003chr data-start=\"526\" data-end=\"529\"\u003e\n\u003cp data-start=\"531\" data-end=\"547\"\u003e\u003cstrong data-start=\"531\" data-end=\"547\"\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"551\" data-end=\"665\"\u003e\n\u003cstrong data-start=\"551\" data-end=\"582\"\u003e10-Foot Extension Harness –\u003c\/strong\u003e Adds extra length for mounting an MP Alert light toward the bow or forward deck.\u003c\/li\u003e\n\u003cli data-start=\"668\" data-end=\"782\"\u003e\n\u003cstrong data-start=\"668\" data-end=\"691\"\u003ePlug-and-Play Fit –\u003c\/strong\u003e Connects directly to the existing MP Alert harness with OEM SmartCraft-grade connectors.\u003c\/li\u003e\n\u003cli data-start=\"785\" data-end=\"896\"\u003e\n\u003cstrong data-start=\"785\" data-end=\"815\"\u003eSupports Safety Coverage –\u003c\/strong\u003e Helps position lights where they’re easier for swimmers and passengers to see.\u003c\/li\u003e\n\u003cli data-start=\"899\" data-end=\"993\"\u003e\n\u003cstrong data-start=\"899\" data-end=\"921\"\u003eFlexible Routing –\u003c\/strong\u003e Long enough to run through consoles, side panels, or bow passageways.\u003c\/li\u003e\n\u003cli data-start=\"996\" data-end=\"1103\"\u003e\n\u003cstrong data-start=\"996\" data-end=\"1018\"\u003eOEM Marine Build –\u003c\/strong\u003e Weather-sealed cable designed to handle vibration, spray, and temperature changes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1105\" data-end=\"1108\"\u003e\n\u003cp data-start=\"1110\" data-end=\"1127\"\u003e\u003cstrong data-start=\"1110\" data-end=\"1127\"\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"1131\" data-end=\"1175\"\u003eMP Alert systems (all oval-light versions)\u003c\/li\u003e\n\u003cli data-start=\"1178\" data-end=\"1209\"\u003eSmartCraft-compatible engines\u003c\/li\u003e\n\u003cli data-start=\"1212\" data-end=\"1253\"\u003eAdditional or relocated MP Alert lights\u003c\/li\u003e\n\u003cli data-start=\"1256\" data-end=\"1307\"\u003eBoats needing forward-facing Moving Prop warnings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1309\" data-end=\"1312\"\u003e\n\u003cp data-start=\"1314\" data-end=\"1350\"\u003e\u003cstrong data-start=\"1314\" data-end=\"1350\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1352\" data-end=\"1810\"\u003eThis harness lets you extend your safety zone by adding or relocating a Moving Prop Alert light to the front of the boat. The extra 10 feet give you room to route the cable cleanly through bulkheads and rigging channels, keeping your wiring neat and protected. Once connected, the forward light activates automatically with the rest of the MP Alert system, flashing whenever the prop is turning so people approaching from the bow can clearly see the warning.\u003c\/p\u003e\n\u003chr data-start=\"1812\" data-end=\"1815\"\u003e\n\u003cp data-start=\"1817\" data-end=\"1832\"\u003e\u003cstrong data-start=\"1817\" data-end=\"1832\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1834\" data-end=\"2195\"\u003eThe MP Alert system depends on reliable signaling and solid, sealed connectors. Mercury’s OEM extension harness fits correctly, keeps moisture out, and preserves the timing and brightness of the warning lights. Aftermarket extensions often introduce weak connections or intermittent behavior, but the factory harness keeps the system consistent and trustworthy.\u003c\/p\u003e\n\u003chr data-start=\"2197\" data-end=\"2200\"\u003e\n\u003cp data-start=\"2202\" data-end=\"2209\"\u003e\u003cstrong data-start=\"2202\" data-end=\"2209\"\u003eFAQ\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2211\" data-end=\"2382\"\u003e\u003cstrong data-start=\"2211\" data-end=\"2260\"\u003eQ1: When would I need this extension harness?\u003c\/strong\u003e\u003cbr data-start=\"2260\" data-end=\"2263\"\u003eWhen mounting an MP Alert light toward the front of the boat or when the standard harness is too short for your layout.\u003c\/p\u003e\n\u003cp data-start=\"2384\" data-end=\"2512\"\u003e\u003cstrong data-start=\"2384\" data-end=\"2441\"\u003eQ2: Does installing this change how the system works?\u003c\/strong\u003e\u003cbr data-start=\"2441\" data-end=\"2444\"\u003eNo. It simply extends the wiring—activation remains fully automatic.\u003c\/p\u003e\n\u003cp data-start=\"2514\" data-end=\"2636\"\u003e\u003cstrong data-start=\"2514\" data-end=\"2562\"\u003eQ3: Is it compatible with all MP Alert kits?\u003c\/strong\u003e\u003cbr data-start=\"2562\" data-end=\"2565\"\u003eYes.
