Proper air gap between the trigger\/sensor components and the stator charge coils is essential for accurate ignition timing, and this locator ring provides a repeatable, consistent spacing reference so the gap can be set correctly during ignition system service, stator replacement, or general engine maintenance.\u003c\/p\u003e\u003cp\u003eDesigned as a purpose-built gauge rather than a general-purpose spacer, the locator ring removes the guesswork from manually measuring the sensor air gap with feeler gauges, helping technicians and boat owners restore the factory-specified clearance. It is intended for use on 2 cylinder Johnson and Evinrude outboard applications during ignition component servicing.\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 18-99544\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Johnson Evinrude 2 Cylinder Outboard Motors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Sets sensor and stator charge coil air gap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282395742\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson and Evinrude 2 cylinder outboard motors\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99544 locator ring used for?\u003c\/strong\u003e The Sierra 18-99544 locator ring is used to set the sensor and stator charge coil air gap on Johnson and Evinrude 2 cylinder outboard motors during ignition system service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich engines does the 18-99544 locator ring fit?\u003c\/strong\u003e This locator ring is designed for Johnson and Evinrude 2 cylinder outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the sensor air gap need to be set with a tool like this?\u003c\/strong\u003e Accurate ignition timing depends on a consistent gap between the sensor and the stator charge coils, and the 18-99544 locator ring provides a repeatable spacing reference so this gap is set correctly rather than estimated by hand.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-99544 locator ring weigh?\u003c\/strong\u003e It weighs 1.5 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a wear part or a setting\/service tool?\u003c\/strong\u003e The 18-99544 is a service tool (a locator ring) used to set the sensor and stator charge coil air gap rather than a running engine component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need this tool for a stator replacement on a 2 cylinder Johnson or Evinrude?\u003c\/strong\u003e Yes, when replacing or servicing the stator or sensor on a 2 cylinder Johnson or Evinrude outboard, the 18-99544 locator ring helps set the correct air gap during reassembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99544 an OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-99544 is sold under the Sierra brand as the part number for this locator ring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes with the Sierra 18-99544?\u003c\/strong\u003e The product is the locator ring itself, used as a setting gauge for the sensor and stator charge coil air gap on applicable 2 cylinder outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this locator ring be used on more than 2 cylinder models?\u003c\/strong\u003e The Sierra 18-99544 locator ring is intended for Johnson and Evinrude 2 cylinder outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat identifies this part when ordering?\u003c\/strong\u003e Order by Sierra part number 18-99544, described as the Locator Ring for Johnson Evinrude 2 cylinder outboard applications.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988446490843,"sku":"SIE-18-99544","price":122.35,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-553-4994_lg__96018.1558114043.500.750.jpg?v=1785189080","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-99544-locator-ring-sensor-gap-ring-for-johnson-evinrude-2-cylinder-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
