Penrite Marine Gear Oil 75W-90 is a premium full synthetic gear lubricant designed specifically for outboard and stern-drive lower units. It provides excellent protection in both saltwater and freshwater environments, offering smooth gear engagement, outstanding load-carrying capability, and long-term resistance to heat and oxidation.

Formulated for high-performance marine applications, it is ideal for NZ boat owners needing reliable protection for gear cases operating under heavy load, high RPM and harsh conditions. The blue colour helps distinguish it from standard automotive gear oils, reducing the risk of misapplication.
