The Mercury 8M0109507 Moving Prop Alert Light System adds a bright, unmistakable visual warning that activates automatically whenever the prop is in motion. Designed for SmartCraft-compatible engines, this oval-style kit uses dual LED smart lights and a control module linked directly to the engine computer, giving everyone around the boat a clear signal when it’s unsafe to be near the prop.\u003c\/p\u003e\n\u003chr data-start=\"625\" data-end=\"628\"\u003e\n\u003cp data-start=\"630\" data-end=\"646\"\u003e\u003cstrong data-start=\"630\" data-end=\"646\"\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"650\" data-end=\"755\"\u003e\n\u003cstrong data-start=\"650\" data-end=\"673\"\u003eDual Smart Lights –\u003c\/strong\u003e Two oval lights, each built with six bright LEDs for high, day-visible warning.\u003c\/li\u003e\n\u003cli data-start=\"758\" data-end=\"886\"\u003e\n\u003cstrong data-start=\"758\" data-end=\"796\"\u003eSmartCraft-Linked Control Module –\u003c\/strong\u003e Ties directly into the engine computer so the lights activate only when the prop turns.\u003c\/li\u003e\n\u003cli data-start=\"889\" data-end=\"996\"\u003e\n\u003cstrong data-start=\"889\" data-end=\"919\"\u003e20-Foot Harness Included –\u003c\/strong\u003e Long enough for most transom routings; additional lengths sold separately.\u003c\/li\u003e\n\u003cli data-start=\"999\" data-end=\"1110\"\u003e\n\u003cstrong data-start=\"999\" data-end=\"1027\"\u003eAutomatic Safety Alert –\u003c\/strong\u003e No switches—lights come on anytime the engine is running and the prop is moving.\u003c\/li\u003e\n\u003cli data-start=\"1113\" data-end=\"1228\"\u003e\n\u003cstrong data-start=\"1113\" data-end=\"1138\"\u003eExpandable Coverage –\u003c\/strong\u003e Compatible with additional smart lights for even greater visibility around the transom.\u003c\/li\u003e\n\u003cli data-start=\"1231\" data-end=\"1331\"\u003e\n\u003cstrong data-start=\"1231\" data-end=\"1263\"\u003eComplete Mounting Hardware –\u003c\/strong\u003e Includes brackets and fasteners for a clean, secure installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1333\" data-end=\"1336\"\u003e\n\u003cp data-start=\"1338\" data-end=\"1355\"\u003e\u003cstrong data-start=\"1338\" data-end=\"1355\"\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAll \u003cstrong data-start=\"1363\" data-end=\"1396\"\u003eSmartCraft-compatible engines\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eOval MP Alert light shape\u003c\/li\u003e\n\u003cli\u003eOptional add-on smart lights\u003c\/li\u003e\n\u003cli\u003eBoats wanting an integrated prop-motion warning system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1522\" data-end=\"1525\"\u003e\n\u003cp data-start=\"1527\" data-end=\"1563\"\u003e\u003cstrong data-start=\"1527\" data-end=\"1563\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1565\" data-end=\"2080\"\u003eThis system gives your boat a clear, instant way to warn swimmers when the propeller is turning. The smart lights flash brightly—even in full sunlight—making it easy for anyone in the water to understand the danger zone around the stern. Because the module communicates directly with SmartCraft, activation is automatic and perfectly timed with engine behavior. The 20-foot harness provides enough length for clean routing on most setups, and the low-profile oval lights mount neatly without cluttering the transom.\u003c\/p\u003e\n\u003chr data-start=\"2082\" data-end=\"2085\"\u003e\n\u003cp data-start=\"2087\" data-end=\"2102\"\u003e\u003cstrong data-start=\"2087\" data-end=\"2102\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2104\" data-end=\"2492\"\u003eProp-alert systems need flawless communication with the engine, and Mercury’s OEM module uses SmartCraft logic to deliver precise, reliable activation. Off-brand products often guess based on vibration or RPM pickup, which can lead to false alerts—or worse, missed alerts.
