Keep your marine engine and hardware running smoothly with this multi-purpose lubricant engineered specifically for saltwater environments. Marine 6-56® forms a clear, thin protective film that lubricates moving parts, displaces moisture, and guards against the accelerated wear and corrosion that salt air and water cause over time.
Whether you're dealing with a wet engine that won't fire, seized hardware, or connections exposed to the elements, this formula cuts through the problem fast — and keeps working long after application.

- Displaces moisture to help start wet or flooded engines
- Loosens rusted, seized, or corroded parts and fasteners
- Protects against ongoing saltwater corrosion
