The Mercury 8M0105518 SmartCraft Authentication Device provides that authorization, allowing applicable Medallion, FW Murphy, and similar gauges to communicate properly with both mechanical and Digital Throttle and Shift MerCruiser engines. Once installed, the system unlocks the advanced SmartCraft functions those gauges were built to display, giving you a cleaner, more capable helm without changing your existing instrumentation.\u003c\/p\u003e\n\u003chr data-start=\"678\" data-end=\"681\"\u003e\n\u003cp data-start=\"683\" data-end=\"699\"\u003e\u003cstrong data-start=\"683\" data-end=\"699\"\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"703\" data-end=\"796\"\u003e\n\u003cstrong data-start=\"703\" data-end=\"733\"\u003eAuthentication Interface –\u003c\/strong\u003e Enables SmartCraft features on supported third-party gauges.\u003c\/li\u003e\n\u003cli data-start=\"799\" data-end=\"902\"\u003e\n\u003cstrong data-start=\"799\" data-end=\"832\"\u003eMechanical \u0026amp; DTS Compatible –\u003c\/strong\u003e Works with mechanical MerCruiser gas engines and all DTS platforms.\u003c\/li\u003e\n\u003cli data-start=\"905\" data-end=\"1015\"\u003e\n\u003cstrong data-start=\"905\" data-end=\"935\"\u003eExpanded Gauge Functions –\u003c\/strong\u003e Allows advanced SmartCraft data and alerts to pass through approved displays.\u003c\/li\u003e\n\u003cli data-start=\"1018\" data-end=\"1113\"\u003e\n\u003cstrong data-start=\"1018\" data-end=\"1043\"\u003ePlug-In Integration –\u003c\/strong\u003e Connects cleanly between the engine and the supported gauge system.\u003c\/li\u003e\n\u003cli data-start=\"1116\" data-end=\"1221\"\u003e\n\u003cstrong data-start=\"1116\" data-end=\"1145\"\u003eOEM Communication Logic –\u003c\/strong\u003e Matches Mercury’s protocol for accurate data transfer and feature access.\u003c\/li\u003e\n\u003cli data-start=\"1224\" data-end=\"1323\"\u003e\n\u003cstrong data-start=\"1224\" data-end=\"1251\"\u003eHelm Upgrade Solution –\u003c\/strong\u003e Lets you modernize gauge capability without changing engine controls.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1325\" data-end=\"1328\"\u003e\n\u003cp data-start=\"1330\" data-end=\"1361\"\u003e\u003cstrong data-start=\"1330\" data-end=\"1361\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"1365\" data-end=\"1416\"\u003eMarine-specific MerCruiser mechanical gas engines\u003c\/li\u003e\n\u003cli data-start=\"1419\" data-end=\"1466\"\u003eMerCruiser Digital Throttle and Shift engines\u003c\/li\u003e\n\u003cli data-start=\"1469\" data-end=\"1499\"\u003eSupported Medallion displays\u003c\/li\u003e\n\u003cli data-start=\"1502\" data-end=\"1532\"\u003eSupported FW Murphy displays\u003c\/li\u003e\n\u003cli data-start=\"1535\" data-end=\"1608\"\u003eThird-party SmartCraft-capable gauges approved for use with this device\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1610\" data-end=\"1613\"\u003e\n\u003cp data-start=\"1615\" data-end=\"1651\"\u003e\u003cstrong data-start=\"1615\" data-end=\"1651\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1653\" data-end=\"2141\"\u003eOnce the authentication device is in place, applicable third-party displays can fully interact with SmartCraft data instead of only showing basic readings. This opens up features like advanced engine parameters, warnings, and functions that normally require Mercury-specific instrumentation. The installation is straightforward, and the communication stays stable even in boats with longer wiring runs. It gives older helms a meaningful upgrade without replacing the entire gauge package.\u003c\/p\u003e\n\u003chr data-start=\"2143\" data-end=\"2146\"\u003e\n\u003cp data-start=\"2148\" data-end=\"2163\"\u003e\u003cstrong data-start=\"2148\" data-end=\"2163\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2165\" data-end=\"2603\"\u003eSmartCraft communication is very exact, and the system expects a proper authentication signal before unlocking advanced data. Mercury’s OEM device uses the same logic built into factory displays, ensuring clean data flow and reliable feature access. Aftermarket attempts rarely match the protocol precisely, which can cause missing information or unstable behavior. With the OEM module, everything communicates the way the engine expects.\u003c\/p\u003e\n\u003chr data-start=\"2605\" data-end=\"2608\"\u003e\n\u003cp data-start=\"2610\" data-end=\"2617\"\u003e\u003cstrong data-start=\"2610\" data-end=\"2617\"\u003eFAQ\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2619\" data-end=\"2814\"\u003e\u003cstrong data-start=\"2619\" data-end=\"2674\"\u003eQ1: How do I know if my gauge requires this device?\u003c\/strong\u003e\u003cbr data-start=\"2674\" data-end=\"2677\"\u003eIf your third-party gauge supports SmartCraft features but will not access them without authorization, this device is typically required.\u003c\/p\u003e\n\u003cp data-start=\"2816\" data-end=\"2964\"\u003e\u003cstrong data-start=\"2816\" data-end=\"2872\"\u003eQ2: Does this module change how the engine operates?\u003c\/strong\u003e\u003cbr data-start=\"2872\" data-end=\"2875\"\u003eNo. It only enables communication and does not alter throttle, shift, or engine behavior.\u003c\/p\u003e\n\u003cp data-start=\"2966\" data-end=\"3118\"\u003e\u003cstrong data-start=\"2966\" data-end=\"3026\"\u003eQ3: Do I need a specific wiring layout for installation?\u003c\/strong\u003e\u003cbr data-start=\"3026\" data-end=\"3029\"\u003eYou just need a supported third-party gauge and the standard SmartCraft connection route.\u003c\/p\u003e\n\u003cp data-start=\"3120\" data-end=\"3296\"\u003e\u003cstrong data-start=\"3120\" data-end=\"3168\"\u003eQ4: Can this be used on multi-engine setups?\u003c\/strong\u003e\u003cbr data-start=\"3168\" data-end=\"3171\"\u003eThis device is intended for setups using supported single-engine or appropriately configured multi-engine SmartCraft systems.\u003c\/p\u003e\n\u003cp data-start=\"3298\" data-end=\"3444\"\u003e\u003cstrong data-start=\"3298\" data-end=\"3343\"\u003eQ5: Will saltwater use affect the module?\u003c\/strong\u003e\u003cbr data-start=\"3343\" data-end=\"3346\"\u003eWhen mounted and sealed correctly, it holds up well in both freshwater and saltwater environments.\u003c\/p\u003e","brand":"Mercury","offers":[{"title":"Default Title","offer_id":46935285006627,"sku":"8M0105518","price":552.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/7410\/9475\/files\/PV505931.jpg?v=1698792773","url":"https:\/\/partsvu.com\/en-au\/products\/mercury-authentic-device-8m0105518","provider":"PartsVu","version":"1.0","type":"link"}
