The kit is built around a brass prop nut and keeper, paired with a cotter pin and a prop spacer, giving you every fastener needed to reinstall or replace worn propeller hardware in one package. The prop nut and keeper are machined brass with an internal #4 UNC thread, finished for corrosion resistance in a marine environment, while the cotter pin locks the nut in place so it cannot back off during operation. Sierra part number 18-3715 directly replaces OEM number 175266, so it drops into the same application without modification.\u003c\/p\u003e\u003cp\u003eThis kit is sized as a small hardware set, making it an easy on-hand spare for seasonal prop changes, storage prep, or replacing hardware lost or damaged during a prop strike. Because it includes the nut, keeper, cotter pin, and spacer together, there is no need to source each piece individually or guess at compatible sizing.\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 18-3715\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Prop Nut Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Thread Size:\u003c\/strong\u003e #4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type:\u003c\/strong\u003e Unified National Coarse (UNC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style:\u003c\/strong\u003e Internal, #4, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\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 0.44 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Prop Nut\/Keeper (18-3708-1), Cotter Pin (18-3741), Prop Spacer (18-4231)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude outboard motor\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e175266\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3715 prop nut kit include?\u003c\/strong\u003e The kit contains a brass prop nut with keeper (18-3708-1), a cotter pin (18-3741), and a prop spacer (18-4231), giving you the complete set of hardware needed to mount a propeller.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-3715 replace?\u003c\/strong\u003e Sierra 18-3715 replaces OEM number 175266 on Johnson\/Evinrude outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is this prop nut kit designed for?\u003c\/strong\u003e This kit is designed for Johnson and Evinrude outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the prop nut made from?\u003c\/strong\u003e The prop nut and keeper in kit 18-3715 are machined brass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the 18-3715 prop nut use?\u003c\/strong\u003e The prop nut has a 1\/4 inch thread with an internal #4 Unified National Coarse (UNC) thread, right hand style.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a cotter pin included with this kit?\u003c\/strong\u003e Yes, the Sierra 18-3715 kit includes cotter pin 18-3741 to lock the prop nut in place.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3715 prop nut kit weigh?\u003c\/strong\u003e The complete kit weighs 0.44 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the prop nut kit?\u003c\/strong\u003e The Sierra 18-3715 prop nut kit has a white finish on the packaging\/nut components as listed by the manufacturer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit include a prop spacer?\u003c\/strong\u003e Yes, prop spacer 18-4231 is included along with the prop nut, keeper, and cotter pin in kit 18-3715.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-3715 a genuine aftermarket replacement or OEM part?\u003c\/strong\u003e Sierra 18-3715 is an aftermarket replacement kit engineered to replace OEM number 175266 on Johnson\/Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the individual components in the kit?\u003c\/strong\u003e Individual hardware pieces in the 18-3715 kit measure approximately 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988162457819,"sku":"SIE-18-3715","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3715_lg__07686.1558126596.500.750.jpg?v=1785188064","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3715-prop-nut-kit-for-johnson-evinrude-replaces-oem-175266-prop-nut-keeper-cotter-pin-prop-spacer","provider":"Good Vibes Marina","version":"1.0","type":"link"}
