Purpose and Specifications

MOTUL TRANSLUBE SAE90 is a tough mineral gear oil built for heavy-duty transmissions and outboard propeller boxes in boats like Evinrude, Johnson, Mercury, and Suzuki. Its API GL-4 rating handles high-pressure gears without breaking down, while SAE90 viscosity keeps a thick protective film from -10°C to 150°C operating temps.

This 20L bulk pack delivers high lubricating power that cuts friction and wear, quiets noisy gearboxes, and fights corrosion with extreme pressure additives. Anti-foam and anti-emulsion formulas prevent water mix-ups in marine use, extending gear life in harsh saltwater conditions.

• Reduces gear noise for smoother, quieter shifts
• Protects against wear under heavy loads and high heat
• Resists water contamination - ideal for boats and wet environments
• Shelf life: 5 years unopened in cool, dry storage

When to Use / Replace?

Use in manual transmissions, differentials, and marine lower units calling for SAE90 GL-4 oil. Perfect for boats, trucks, and off-road rigs facing extreme pressure. Replace every 20,000 km or 12 months in daily drivers, or every season for marine use - check levels monthly in saltwater boats.

Drain and refill if oil turns dark, milky from water, or after hitting water/deep fording. Handles up to 150°C without thinning out.

FAQ

Q: Is this safe for my boat's outboard propeller box?
A: Yes, specially made for Evinrude, Mercury, Suzuki, and more - anti-emulsion tech keeps it working even with water exposure.

Q: How often should I change it in my truck transmission?
A: Every 20,000 km or yearly under normal use; more often if towing heavy loads or off-roading.

Q: Can I mix it with other gear oils?
A: Best to fully drain old oil first for top protection - compatible with most mineral GL-4 oils but avoid synthetics.
