Quicksilver SAE 90 High Performance Gear Lube is a 32 oz (946 mL) gear oil formulated to protect outboard lower units and sterndrive gear housings in applications above 75 hp.

• SAE 90 viscosity — made for marine lower-unit gear lubrication.
• Formulated to help protect against corrosion and excessive wear — supports protection of internal gears.
• Extreme-pressure synthetic additives — help protect gears from metal-to-metal contact.
• Designed to help prevent failures caused by water entering the gear housing — addresses a specific lower-unit risk.
• Manufacturer part number 8M0222065 — identifies this Quicksilver formulation.

Lower-unit gears operate in a housing where water intrusion can contribute to damage. This oil is made for sterndrive and outboard applications, with a formulation focused on corrosion, wear, and gear contact. Choose it for a compatible marine application above 75 hp when selecting SAE 90 lower-unit gear oil.

What does Quicksilver SAE 90 Gear Lube protect against?

It is formulated to protect lower-unit gears against corrosion and excessive wear, and to help prevent failures related to water entering the gear housing.
