This Quicksilver SAE 90 formula is engineered specifically for marine lower units — sterndrives and outboards above 75 hp — combining SAE 90 viscosity with extreme-pressure additives to reduce metal-to-metal contact and defend against corrosion when water intrusion occurs. The 32-ounce bottle makes routine service straightforward and matches factory specifications for many Mercury Marine and other original-equipment applications.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this gear lube protect gears during heavy use?\u003c\/h3\u003e\n\u003cp\u003eThe formulation contains extreme-pressure synthetic additives that cling to gear surfaces to prevent direct metal contact under load.
