For a 1975 Johnson 25hp Tiller Engine, it's recommended to use a high-quality gear lube specifically formulated for marine outboards. Typically, a 90-weight gear oil, such as a TC-W3 rated oil, is suitable for the lower unit. Always check the owner's manual for any specific requirements or recommendations. Regular maintenance and using the correct lube will help ensure optimal performance and longevity of the engine.
