It threads onto the bottle itself, letting you pump lube directly into the fill hole without messing with squeeze tubes or funnels, which keeps the job neater and reduces spills in the process.\u003c\/p\u003e\u003cp\u003eThis pump is built to work with both standard and wide mouth gear lube bottles, so it is not tied to one bottle size or brand. It comes with a set of adapters covering all major outboard engine manufacturers, which means one pump can handle a wide range of gear lube bottle threads you are likely to encounter in the shop or on the dock. The pump body and fittings are constructed from aluminum for durability and long service life, standing up to repeated use and exposure to gear lube and marine environments better than lower-grade plastic pumps.\u003c\/p\u003e\u003cp\u003eSierra ships the 18-9779 display packaged, making it a straightforward addition to a service counter or tool bench. It is a practical accessory for any marine technician, boat owner, or shop that regularly performs gear lube changes and wants a reusable, adapter-equipped pump instead of disposable pour spouts.\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 18-9779\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Gear Lube Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottle Compatibility:\u003c\/strong\u003e Standard and wide mouth bottles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Adapters:\u003c\/strong\u003e Fits all major outboard engine manufacturers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Material:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Display packaged\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\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282375706\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal gear lube pump with adapters for use across all major outboard engine manufacturers; not limited to a single make or model.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury 91-74057Q6\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-9779 used for?\u003c\/strong\u003e It is a gear lube pump that threads onto a bottle of gear lubricant and lets you pump the lube directly into an outboard or sterndrive gear case fill hole, avoiding spills and messy pour spouts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this pump fit any gear lube bottle?\u003c\/strong\u003e The 18-9779 is designed to work with both standard and wide mouth gear lube bottles, and it includes adapters covering all major outboard engine manufacturers, so it fits a wide range of bottle threads without needing a separate pump for each brand.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-9779 come with adapters?\u003c\/strong\u003e Yes, adapters for all major outboard engine manufacturers are included with the Sierra Gear Lube Pump 18-9779, so you can switch between different gear lube bottle brands using the same pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-9779 made of?\u003c\/strong\u003e The pump features aluminum fittings for durability, which is intended to give it a longer service life than pumps built with lower-grade materials.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-9779 an OEM equivalent to a Mercury part?\u003c\/strong\u003e Yes, the Sierra 18-9779 gear lube pump replaces Mercury part number 91-74057Q6 and performs the same function of transferring gear lube from a bottle into a gear case.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra Gear Lube Pump weigh?\u003c\/strong\u003e The Sierra 18-9779 gear lube pump weighs 1 pound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-9779 gear lube pump?\u003c\/strong\u003e The product measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the Sierra 18-9779 come packaged?\u003c\/strong\u003e The 18-9779 ships display packaged, making it easy to hang or shelve at a service counter or shop.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the same 18-9779 pump be reused across different jobs?\u003c\/strong\u003e Yes, because the pump includes adapters for all major outboard engine manufacturers and fits both standard and wide mouth bottles, the same 18-9779 unit can be reused across gear lube changes on different engines rather than needing a dedicated pump per brand.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-9779 Gear Lube Pump?\u003c\/strong\u003e The UPC for the Sierra Gear Lube Pump, part number 18-9779, is 808282375706.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988437217499,"sku":"SIE-18-9779","price":19.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-9779__47274.1772544216.500.750.png?v=1785188106","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-9779-gear-lube-pump-replaces-mercury-91-74057q6-fits-standard-and-wide-mouth-gear-oil-bottles-universal-outboard-adapters","provider":"Good Vibes Marina","version":"1.0","type":"link"}
