Frequently Asked Questions

What makes WestWay Marine Gear Oil suitable for my boat?

WestWay Marine Gear Oil is specifically formulated for marine applications, providing excellent extreme pressure protection, anti-corrosion properties, and low foaming characteristics, all crucial for the harsh marine environment and high RPM operation of outboard and sterndrive gearboxes.

Is this gear oil safe for all types of marine gearboxes?

Yes, this SAE 80W-90 GL-4 gear oil is formulated to be safe for use in gear cases containing yellow metals (e.g., brass or bronze synchronizers) often found in marine transmissions, unlike some GL-5 oils which can be corrosive to these materials. Always confirm your engine manufacturer's specific API GL rating requirement.

How does the universal filling pump work and what engines is it compatible with?

The universal filling pump screws directly onto the 1 Litre bottle and includes multiple adapters (3/8", M10, M8) to fit most drain/fill plugs on major outboard brands like Mercury, Yamaha, Suzuki, Honda, Johnson/Evinrude, Tohatsu, and popular sterndrives such as MerCruiser, OMC, Cobra, and Volvo Penta. It ensures a clean and efficient gear oil replacement.
