Product Description
Brand new, genuine Mercury Mercury Marine / Mercruiser OEM Gearlube 5 Gal, 92-8M0078016. This is a factory original equipment item, not aftermarket.
This is a genuine factory-original Mercury Racing Extreme Performance gear oil, engineered specifically for high-demand marine power units like outboards and sterndrives. The 85W‑90 SAE formulation incorporates advanced emulsifiers that safeguard gearcases against water intrusion, which is crucial in harsh marine environments. Pressure additives and tackifiers improve oil film adhesion, reducing wear under extreme loads, while high-temperature stability preserves horsepower and avoids breakdown during intense use. Packaged in a rugged 5-gallon pail, this product meets Mercury’s OEM performance standards—much tougher than standard motor-boat oils—and is ideal for performance and racing gear cases.
