Instead of relying on an adjustable wrench or pliers that can slip and round off the nut's flats, this wrench is machined to the correct nut dimension for a secure, controlled grip during propeller removal and installation. That precision fit reduces the risk of damaging the nut or the prop shaft while servicing the lower unit.\u003c\/p\u003e\u003cp\u003eBuilt for regular use around salt and fresh water, the wrench is a straightforward addition to any boat owner's or marine technician's toolbox, making routine propeller swaps, inspections, and hub replacements easier to perform correctly the first time.\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 18-4459\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Prop Hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Size Compatibility:\u003c\/strong\u003e 1 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Most sterndrives and 4-cylinder and larger outboards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.56 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999875815\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFits a 1 1\/16 inch propeller nut\u003c\/li\u003e\n\u003cli\u003eFits most sterndrives\u003c\/li\u003e\n\u003cli\u003eFits 4-cylinder and larger outboard motors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat nut size does the Sierra 18-4459 prop wrench fit?\u003c\/strong\u003e The Sierra 18-4459 is sized for a 1 1\/16 inch propeller nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat boats and engines is this prop wrench compatible with?\u003c\/strong\u003e It fits most sterndrives as well as 4-cylinder and larger outboard motors that use a 1 1\/16 inch propeller nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-4459 prop wrench weigh?\u003c\/strong\u003e This wrench weighs 0.56 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use an adjustable wrench instead of this tool?\u003c\/strong\u003e An adjustable wrench can slip or round off the flats on a 1 1\/16 inch propeller nut; the Sierra 18-4459 is machined to that exact size for a more secure grip during removal and installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this tool used for?\u003c\/strong\u003e The Sierra 18-4459 prop wrench is used to loosen and tighten the propeller nut when removing or installing a boat propeller.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the Sierra 18-4459 have?\u003c\/strong\u003e It has a machined finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this wrench made by Sierra or a third party?\u003c\/strong\u003e The 18-4459 prop wrench is a genuine Sierra part, identified by Sierra part number 18-4459.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this fit a 4-cylinder outboard?\u003c\/strong\u003e Yes, the Sierra 18-4459 is listed as fitting 4-cylinder and larger outboard motors with a 1 1\/16 inch propeller nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this wrench work on sterndrive propellers?\u003c\/strong\u003e Yes, the 18-4459 is compatible with most sterndrive applications using a 1 1\/16 inch propeller nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes in the box with the Sierra 18-4459?\u003c\/strong\u003e The Sierra 18-4459 is a single prop wrench tool.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988198371547,"sku":"SIE-18-4459","price":29.72,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-4459_lg__45799.1558126754.500.750.jpg?v=1785188151","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-4459-prop-wrench-for-mercury-mariner-outboards-sterndrives-replaces-91-821887a1-fits-1-1-16-in-prop-nut","provider":"Good Vibes Marina","version":"1.0","type":"link"}
