Description
Description
Sierra Full Synthetic Premium Marine Gear Lubricant 946ml is a high-performance 75W90 GL-5 rated full synthetic gear oil specifically formulated for outboard and stern drive gearcases operating in demanding marine conditions. Manufactured from premium synthetic base oils with a carefully balanced additive package, it provides superior protection against wear and corrosion whilst maintaining its viscosity across a wide range of ambient operating temperatures. The full synthetic formulation delivers improved performance over conventional mineral-based gear oils, ensuring critical drive gears are protected for extended service intervals.
Engineered to meet API GL-5, MIL-L-2105E, and SAE J2360 standards, the lubricant is suited to high-performance and high-load operating conditions found in both inboard-outboard lower units and outboard gearcases. Its additive technology is specifically formulated to address the challenges of the marine environment, including water contamination and extreme pressure, maintaining reliable protection from launch to retrieval.
