It mounts with screws and uses a screw-type connector across 2 contacts and 2 poles, matching the original electrical layout of the engines it is designed to replace on. This stator is a direct fit for Johnson\/Evinrude 50 HP outboards produced in 1971-1975 and 55 HP outboards produced in 1976-1977, restoring reliable spark and charging performance on these older powerheads.\u003c\/p\u003e\u003cp\u003eStators are a common wear item on vintage outboards, and a failing unit typically shows up as hard starting, weak or intermittent spark, or a charging system that no longer keeps the battery topped up. The Sierra 18-99239 is manufactured to correctly replace the factory unit on these applications, using the same screw-mount installation and 2-pole, 2-contact wiring so it drops into the existing harness without modification.\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 18-99239\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Stator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cylinders:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 6 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Poles:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Contacts:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Screw Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson\/Evinrude 50 HP outboards, 1971-1975\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 55 HP outboards, 1976-1977\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e775530\u003c\/li\u003e\n\u003cli\u003e580809\u003c\/li\u003e\n\u003cli\u003e581232\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-99239 stator fit?\u003c\/strong\u003e The Sierra 18-99239 fits Johnson\/Evinrude 50 HP outboards from 1971-1975 and Johnson\/Evinrude 55 HP outboards from 1976-1977.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99239 a direct replacement for OEM stators?\u003c\/strong\u003e Yes, the 18-99239 is built to replace OEM Johnson\/Evinrude stators listed under numbers 775530, 580809, and 581232 on the applicable 50 HP and 55 HP engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many amps does this stator put out?\u003c\/strong\u003e The Sierra 18-99239 is rated for 6 amps of output on 2-cylinder Johnson\/Evinrude powerheads.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many cylinders is the 18-99239 stator designed for?\u003c\/strong\u003e This stator is built for 2-cylinder Johnson\/Evinrude outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-99239 cross-reference?\u003c\/strong\u003e It cross-references OEM numbers 775530, 580809, and 581232.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the stator mount to the engine?\u003c\/strong\u003e The Sierra 18-99239 uses a screw mount and connects through a screw-type connector with 2 contacts and 2 poles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the box include when ordering part 18-99239?\u003c\/strong\u003e You receive one Sierra 18-99239 stator, ready to install with its screw-mount hardware interface and screw-type electrical connector.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99239 stator weigh?\u003c\/strong\u003e The Sierra 18-99239 weighs 2.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the symptoms of a failing stator on these outboards?\u003c\/strong\u003e Hard starting, weak or intermittent spark, and a charging system that fails to keep the battery charged are common signs that a stator like the 18-99239 needs replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99239 fit both 50 HP and 55 HP Johnson\/Evinrude models?\u003c\/strong\u003e Yes, this single part number covers the 50 HP outboards built 1971-1975 and the 55 HP outboards built 1976-1977.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988439544027,"sku":"SIE-18-99239","price":229.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-173-1232_lg__01039.1558112999.500.750.jpg?v=1785188274","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-stator-for-johnson-evinrude-50-55-hp-2-cyl-outboards-1971-1977-6-amp-replaces-oem-581232-sierra-18-99239","provider":"Good Vibes Marina","version":"1.0","type":"link"}
