Hinge pins secure the drive unit to the transom assembly, and removing or seating them correctly requires a purpose-built tool rather than improvised methods that can damage the pin or the housing bore. The 18-9861 is designed to do this job cleanly, giving technicians and DIY boat owners a direct way to service the hinge pin connection without guesswork.\u003c\/p\u003e\u003cp\u003eConstructed of unfinished stainless steel for corrosion resistance in a marine environment, the tool measures 4 x 1 x 5 inches and weighs 0.13 pounds, making it easy to store in a toolbox or service kit. It is sold as a single tool and finished in white. The 18-9861 cross-references directly to Mercury Marine 91-78310, so it is a straightforward replacement for that OEM tool, and it is intended for use across the full range of Mercury Marine drive units rather than a single model.\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 18-9861\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Hinge Pin Tool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e Mercury Marine 91-78310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Unfinished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 4 x 1 x 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282109691\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 tool per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eAll Mercury Marine drive units\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury Marine 91-78310\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-9861 Hinge Pin Tool used for?\u003c\/strong\u003e It removes and installs hinge pins on all Mercury Marine drive units, giving technicians a direct way to service the transom hinge pin connection without damaging the pin or housing bore.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-9861 replace?\u003c\/strong\u003e The 18-9861 cross-references to Mercury Marine 91-78310, making it a direct replacement for that original equipment tool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich drive units is Sierra 18-9861 compatible with?\u003c\/strong\u003e It is designed to work on all Mercury Marine drive units for removing and installing hinge pins.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-9861 hinge pin tool made from?\u003c\/strong\u003e Stainless steel, left in an unfinished finish, is used for the Sierra 18-9861 to resist corrosion in a marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-9861 Hinge Pin Tool?\u003c\/strong\u003e This tool has a white color.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow big is the Sierra 18-9861 Hinge Pin Tool?\u003c\/strong\u003e The tool measures 4 x 1 x 5 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-9861 weigh?\u003c\/strong\u003e 0.13 pounds is the weight of the Sierra 18-9861 Hinge Pin Tool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-9861 a genuine Sierra part or an aftermarket equivalent?\u003c\/strong\u003e It is a genuine Sierra branded tool, part number 18-9861, manufactured to service Mercury Marine drive units in place of Mercury Marine 91-78310.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-9861?\u003c\/strong\u003e One Sierra 18-9861 Hinge Pin Tool is included per pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-9861 have a UPC for ordering reference?\u003c\/strong\u003e Yes, the UPC for the Sierra 18-9861 Hinge Pin Tool is 808282109691.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-9861 a specialty tool or a general hand tool?\u003c\/strong\u003e It is a specialty service tool made specifically for removing and installing hinge pins on Mercury Marine drive units, not a general-purpose hand tool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-9861 covered under warranty?\u003c\/strong\u003e Sierra 18-9861 is covered under Sierra's standard customer satisfaction warranty.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988437872859,"sku":"SIE-18-9861","price":21.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-9861_lg__49181.1729085892.500.750.jpg?v=1785188710","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-9861-hinge-pin-tool-for-mercury-marine-drive-units-replaces-mercury-91-78310","provider":"Good Vibes Marina","version":"1.0","type":"link"}
