It attaches over the shift cable and is used at the shift plate to ensure the cable is correctly positioned before final tightening, a step that directly affects clean, reliable shifting between forward, neutral, and reverse. The tool has a machined white exterior and is sized for direct fitment onto the shift cable during service work.\u003c\/p\u003e\u003cp\u003eThis tool is intended for technicians and DIY boaters performing shift cable installation, replacement, or adjustment on Bravo drive units. Using the correct adjustment tool helps prevent improper cable tension, which can cause hard shifting, gear slip, or premature wear on the shift cable and drive components. The 18-9807 is a compact, purpose-built tool that takes the guesswork out of this adjustment step.\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 18-9807\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Shift Cable Adjustment Tool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Bravo drive unit shift cable adjustment at the shift plate\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\u003eWeight:\u003c\/strong\u003e 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces:\u003c\/strong\u003e Mercury Marine 91-12427, 91-12427T\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eBravo drive units\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Marine 91-12427\u003c\/li\u003e\n\u003cli\u003eMercury Marine 91-12427T\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-9807 Shift Cable Adjustment Tool used for?\u003c\/strong\u003e It attaches over the shift cable and is used to set proper shift cable adjustment at the shift plate on Bravo drive units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-9807 tool fit Bravo drive units?\u003c\/strong\u003e Yes, the Sierra 18-9807 Shift Cable Adjustment Tool is designed for shift cable adjustment on Bravo drive units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-9807 replace?\u003c\/strong\u003e The Sierra 18-9807 replaces Mercury Marine 91-12427 and 91-12427T.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-9807 the same tool as Mercury Marine 91-12427?\u003c\/strong\u003e Functionally yes, the Sierra 18-9807 is the direct aftermarket equivalent that replaces Mercury Marine 91-12427 and 91-12427T.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the shift cable adjustment tool weigh?\u003c\/strong\u003e The Sierra 18-9807 weighs 0.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-9807 adjustment tool?\u003c\/strong\u003e It measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-9807 tool?\u003c\/strong\u003e The Sierra 18-9807 Shift Cable Adjustment Tool has a white, machined exterior.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the 18-9807 tool work during installation?\u003c\/strong\u003e The tool attaches directly over the shift cable so it can be positioned at the shift plate, allowing the correct cable adjustment to be set before final tightening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy is proper shift cable adjustment important?\u003c\/strong\u003e Correct adjustment, set using a tool like the Sierra 18-9807, helps ensure clean shifting between gears and can prevent hard shifting or premature wear on Bravo drive unit shift components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-9807 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-9807 is the Sierra manufacturer part number for this Shift Cable Adjustment Tool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the 18-9807 tool?\u003c\/strong\u003e The Sierra 18-9807 is sold as the single shift cable adjustment tool.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988437610715,"sku":"SIE-18-9807","price":9.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-9807_lg__27151.1558133474.500.750.jpg?v=1785188082","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-9807-shift-cable-adjustment-tool-for-mercruiser-bravo-sterndrives-replaces-mercury-91-12427","provider":"Good Vibes Marina","version":"1.0","type":"link"}
