The stator is a key component of the engine's ignition and battery charging system — it generates AC current as the flywheel rotates, powering the ignition system and charging the battery. A failed stator typically results in no-spark conditions, intermittent ignition, or loss of battery charging.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMercury outboard engines — verify by part number 878143T05 \/ 398-878143T05\u003c\/li\u003e\n\u003cli\u003eConfirm fitment against your engine's serial number, model year, and Mercury parts diagram before ordering\u003c\/li\u003e\n\u003cli\u003eStator fitment is highly serial-number and production-range specific — HP rating alone is not sufficient to confirm compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eMercury parts diagrams are the authoritative source for stator fitment.

Do not order based on horsepower or model name alone. Always cross-reference the engine serial number against the Mercury parts diagram. Also note that a failed rectifier\/regulator can damage a new stator if not replaced at the same time — recommend inspecting the rectifier before or during installation.\u003c\/p\u003e\n\n\u003ch2\u003eRelated Parts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/cdi-electronics-mercury-stator-replaces-1748778k1-667-1748778k1\"\u003eCDI Electronics Mercury Stator | Replaces 1748778K1 (Aftermarket Option)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/merc-1087\"\u003eMercury MerCruiser Rectifier 8M0058226\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/mercury-oem-ignition-coil-806673t1\"\u003eMercury OEM Ignition Coil 806673T1\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/merc-1005\"\u003eMercury MerCruiser Ignition Sensor Assembly 892150K02\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/cdi-electronics-8-cylinder-spark-gap-tester-adjustable-enclosed-667-5119766\"\u003eCDI Electronics 8-Cylinder Spark Gap Tester | Ignition Diagnostic Tool\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563899879460,"sku":"878143T05","price":418.56,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/e0026f36-3504-4cca-b469-dd343547ec81.png?v=1787257858","url":"https:\/\/marisolmarine.com\/products\/merc-934","provider":"Marisol Marine Company","version":"1.0","type":"link"}
