Purpose and Specifications

MOTUL TRANSLUBE EXPERT 75W90 is a high-performance synthetic gear oil designed to protect outboard motor propeller boxes and manual transmissions under extreme loads. It meets API GL-4 and GL-5 standards, forming a tough oil film that resists wear, cuts friction, and quiets noisy gearboxes even in harsh marine conditions.

• Flows smoothly at cold starts down to -20°C for quick protection.
• Stays thick and strong up to 150°C at full throttle.
• Anti-emulsion formula sheds water to prevent corrosion from saltwater exposure.
• 1L bottle perfect for most outboard lower units like Evinrude, Mercury, Yamaha, and Suzuki.

When to Use / Replace?

Use this oil in high-power outboard engines or manual transmissions facing heavy loads, racing, or frequent saltwater use. Replace every 100,000 km or 2 years for road vehicles, or annually/200 hours for boats to maintain peak performance and avoid gear damage. Shelf life is 5 years unopened in cool, dry storage.
