Marine Gear Oil SAE 90
Premium High-Performance Gearcase Lubricant
Solarika Marine Gear Oil SAE 90 is a specialized extreme-pressure (EP) lubricant engineered specifically for the demanding environment of marine gearcases. Designed for use in both outboard lower units and sterndrive systems, this oil provides a robust protective film that withstands high-torque and high-speed operation. Its advanced additive package is formulated to prevent metal-to-metal contact, extending the life of hypoid gears even under shock-load conditions.
Key Features
- ✔ Extreme Pressure (EP): Protects gears under heavy loads.
- ✔ Water Resistance: Maintains lubrication properties even when contaminated with up to 10% water.
- ✔ Anti-Corrosion: Inhibits rust in humid marine environments.
- ✔ Seal Compatibility: Formulated to keep seals pliable and prevent leaks.

Questions & Answers
Is this a genuine original part?
This is a premium quality Solarika replacement lubricant, manufactured to meet or exceed API GL-5 standards for high-performance marine gearcases.
How do I know if it is compatible?
If your owner's manual specifies an SAE 90, 80W-90, or API GL-5 gear lubricant for your lower unit or sterndrive, this oil is a guaranteed fit.
Can this be used in engines requiring 80W-90?
Yes. While SAE 90 is a single-grade oil, it provides the required viscosity at operating temperatures that 80W-90 multigrade oils offer, often with better shear stability in high-load marine applications.
