It is designed to reduce friction and protect gears, bearings, and other gear case components from wear and corrosion during all standard marine applications. The lubricant has a viscosity of 75W-90 or 80W-90, matching the requirements of most marine lower unit and gear case applications, and comes packaged in a plastic bottle for clean, controlled pouring at the fill and vent plugs.\u003c\/p\u003e\u003cp\u003eThis gear lube is part of the Sierra 18-9600 line and is sold in two sizes to match different service needs: a 10 Oz tube sized for topping off or a single small gear case fill, and a Quart bottle sized for a full lower unit gear lube change or keeping extra lubricant on board for routine maintenance. Both sizes share the same formulation, so the choice comes down to how much lubricant the job requires.\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 18-9600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Lower Unit Gear Lube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLubricant Class:\u003c\/strong\u003e GL-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eViscosity:\u003c\/strong\u003e 75W-90 or 80W-90\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e Freshwater and saltwater marine applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecific Use:\u003c\/strong\u003e Reduces friction and protects gears, bearings, and other gear case components; helps prevent corrosion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Form:\u003c\/strong\u003e Oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Material:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e Bottle\/Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Sizes:\u003c\/strong\u003e 10 Oz, Quart\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mercury 92-802844Q02 (10 Oz size); Mercury 92-858058Q01 (Quart size)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSizes \u0026amp; Options\u003c\/h3\u003e\u003cp\u003eChoose the 10 Oz tube for a quick top-off or a single small-capacity gear case, or choose the Quart bottle for a complete lower unit gear lube change or to keep a fuller supply on hand.
