It is installed on the propeller shaft to properly position the propeller and hub against the thrust washer, ensuring correct spacing and alignment for reliable propeller operation. Built to meet or exceed original equipment quality, this spacer is a direct replacement for the OMC 323943 spacer, making it a straightforward swap when replacing a worn, corroded, or missing prop spacer during propeller service or hardware replacement.\u003c\/p\u003e\u003cp\u003eThis is a small, purpose-built hardware component rather than a multi-piece kit, and it ships as a single spacer per unit. It is intended for buyers who already know their propeller hardware needs replacing and are matching parts by OEM number to ensure correct fitment on Johnson and Evinrude outboards.\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 18-4232\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Prop Spacer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Evinrude Outboard Prop Nuts \u0026amp; Washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999237262\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude outboard motors\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOMC 323943\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-4232 prop spacer fit?\u003c\/strong\u003e The Sierra 18-4232 prop spacer is designed for Johnson\/Evinrude outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-4232 replace?\u003c\/strong\u003e It replaces OMC 323943, so it is a direct swap for that original equipment prop spacer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-4232 prop spacer weigh?\u003c\/strong\u003e This prop spacer weighs 0.02 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spacers come in a package?\u003c\/strong\u003e The Sierra 18-4232 is sold as a single spacer, with a unit count of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-4232 an OEM or aftermarket part?\u003c\/strong\u003e It is an aftermarket replacement built by Sierra to meet or exceed original equipment quality, cross-referenced to OMC 323943.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the prop spacer installed on an outboard?\u003c\/strong\u003e The 18-4232 is installed on the propeller shaft, positioning the propeller and hub correctly for proper spacing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a similar Sierra prop spacer for other applications?\u003c\/strong\u003e Yes, Sierra 18-4231 is a related prop spacer that replaces a different OEM number (320570), so buyers should confirm the correct part number for their application before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-4232 prop spacer?\u003c\/strong\u003e The UPC for this prop spacer is 030999237262.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-4232 spacer fit any outboard brand?\u003c\/strong\u003e No, the Sierra 18-4232 is specifically intended for Johnson\/Evinrude outboard motors, so it should be matched against the OMC 323943 cross-reference before purchase.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy replace a prop spacer instead of reusing the old one?\u003c\/strong\u003e A worn, corroded, or damaged prop spacer can allow improper propeller positioning, so replacing it with the Sierra 18-4232 restores correct fit against the thrust washer.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988172091611,"sku":"SIE-18-4232","price":5.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-4232_lg__68860.1558127219.500.750.jpg?v=1785188161","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-4232-prop-spacer-for-johnson-evinrude-omc-outboards-replaces-omc-319890","provider":"Good Vibes Marina","version":"1.0","type":"link"}
