Product: 23323
Meets Industry Specifications
  • API - GL-5
  • MIL - L-2105 D

Is an extreme-pressure lubricant for gear boxes, specially formulated to satisfy the highest service conditions of gears used in inboard and outboard marine applications. Its high oxidation stability minimises sludge and deposit formation facilitating longer component life and protects equipment against rust and corrosion under marine environment. It protects gear components in applications where there is high torque at low speeds and where extreme pressures and shock loading are encountered.


This oil is recommended for inboard and outboard gear cases from major global manufacturers including Evinrude, Johnson, Mariner, Suzuki, Honda, Yamaha, Tohatsu, Nissan, requiring API GL 5 quality oils. May not be suitable for some models which call for special fluid (particularly jet units). Please check user's manual prior to selection of lubricant.


Reliable formulation, based on excellent components, which contributes to good gear performance, easy shifting and long service.
