Mercury SAE 90 Gear Lube, 1 Quart 8M0222063

Mercury SAE 90 Gear Lube, High Performance 1 Quart 8M0222063 is a genuine OEM lubricant formulated to protect lower units in Mercury and Mariner outboards, jet pumps, and MerCruiser sterndrives requiring SAE 90 gear lube. Designed for engines 75HP and above, this high-performance lubricant helps reduce friction, minimize wear, and provide superior protection against corrosion in demanding marine environments.

Compatible with the following:

• Mercury outboards 75HP and above requiring SAE 90 High Performance Gear Lube
• Mariner outboards 75HP and above requiring SAE 90 High Performance Gear Lube
• MerCruiser sterndrives requiring SAE 90 High Performance Gear Lube

Formulated with advanced extreme-pressure additives, this premium gear lubricant helps protect gears and bearings from metal-to-metal contact under heavy loads. It also provides excellent corrosion resistance and helps safeguard internal components if water enters the gearcase, reducing the risk of premature wear and gear failure.

Routine lower unit oil changes are essential for maximizing gearcase life and maintaining reliable performance. Fresh gear lube helps keep internal components properly lubricated while allowing you to inspect for signs of water intrusion or excessive wear during scheduled maintenance. The convenient 1-quart bottle is ideal for routine service on many compatible lower units and can be used with the Mercury Gear Lube Pump (8M0222068) for clean, easy filling.
