Cotter pins are a small but critical piece of outboard prop hardware: they lock the propeller nut in place on the prop shaft so vibration and water pressure cannot back it off, which protects the propeller from working loose or being lost during operation. Because they are a wear item that should be replaced (not reused) any time the propeller is removed for service, having a full pack of 10 on hand covers multiple prop changes or a season of routine maintenance across more than one boat.\u003c\/p\u003e\u003cp\u003eEach pin in this pack is finished in a grey tone and sized at 0.39 x 0.39 x 0.39 inches. The 18-2380-9 is manufactured to meet or exceed the original equipment part it replaces, making it a direct fit for the Yamaha prop nut hardware it is designed for.\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 18-2380-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Cotter Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 10 cotter pins\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Type:\u003c\/strong\u003e Cotter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha outboard prop nut hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Yamaha outboard propeller nut hardware.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e91490-30030-00\u003c\/li\u003e\n\u003cli\u003e91401-30028-00\u003c\/li\u003e\n\u003cli\u003e91401-30030-00\u003c\/li\u003e\n\u003cli\u003e91402-30022-00\u003c\/li\u003e\n\u003cli\u003e91402-30022-09\u003c\/li\u003e\n\u003cli\u003e91402-30028-00\u003c\/li\u003e\n\u003cli\u003e91402-30028-09\u003c\/li\u003e\n\u003cli\u003e91490-30022-00\u003c\/li\u003e\n\u003cli\u003e91490-30025-00\u003c\/li\u003e\n\u003cli\u003eGLM 22090\u003c\/li\u003e\n\u003cli\u003eMallory 9-73911\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2380-9 cotter pin used for?\u003c\/strong\u003e It locks the propeller nut onto a Yamaha outboard prop shaft so vibration and water pressure cannot back the nut off, keeping the propeller securely in place during operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many pins come in a pack of the 18-2380-9?\u003c\/strong\u003e Each package of the Sierra 18-2380-9 contains 10 cotter pins.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size are the 18-2380-9 cotter pins?\u003c\/strong\u003e Each pin measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does a pack of 18-2380-9 cotter pins weigh?\u003c\/strong\u003e A package of the Sierra 18-2380-9 weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does the 18-2380-9 cotter pin replace?\u003c\/strong\u003e Sierra 18-2380-9 replaces Yamaha 91490-30030-00, 91401-30028-00, 91401-30030-00, 91402-30022-00, 91402-30022-09, 91402-30028-00, 91402-30028-09, 91490-30022-00, and 91490-30025-00, as well as GLM 22090 and Mallory 9-73911.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2380-9 a genuine Yamaha part or aftermarket?\u003c\/strong\u003e It is an aftermarket cotter pin manufactured to meet or exceed the original equipment Yamaha part it replaces, rather than a Yamaha-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color are these cotter pins?\u003c\/strong\u003e The 18-2380-9 cotter pins are finished in grey.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan cotter pins be reused after removing the prop nut?\u003c\/strong\u003e Cotter pins are a wear item meant to be replaced each time the propeller nut is removed, which is why the Sierra 18-2380-9 comes packaged in a set of 10 for repeated servicing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in a package of the Sierra 18-2380-9?\u003c\/strong\u003e The package includes 10 individual cotter pins sized for Yamaha outboard prop nut hardware.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2380-9 fit any outboard brand's prop hardware?\u003c\/strong\u003e The Sierra 18-2380-9 is designed for Yamaha outboard prop nut hardware and cross-references specifically to Yamaha OEM cotter pin numbers.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988106096859,"sku":"SIE-18-2380-9","price":23.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2380-9__83323.1737878208.500.750.jpg?v=1785188754","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2380-9-stainless-steel-cotter-pin-pack-of-10-for-yamaha-f9-9-15-outboards-replaces-oem-91490-30030-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
