Your marine gearbox is chewing itself up. Thermal breakdown, foaming under sustained load, EP additives that have long since evaporated — that's why the gears grind and the seal weeps after a hard day on the water. This 1-litre bottle of Ichiro hydrotreated SAE 90 gear oil is blended with high EP additives (API GL-5) and an anti-foam package to keep your differential or steering gearbox protected through a full Australian summer. Chemical and thermal stability rated for sustained high-pressure contact between teeth. Pour, cap, done. Your next service interval just got a lot less stressful
