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.

RELIABILITY: Formulated to meet API GL-5 standards, providing superior protection against corrosion and gear pitting in both salt and freshwater environments.

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.
