More Information
Summary:A transparent container (20, 48) is mounted to the inner transom wall (2) of a boat (3) and is connected to the oil passages in a stern drive unit (1). The container is provided with a removable cap (25) having a one-way valve (27) of the Vernay type therein. The valve prevents outward leakage of lubricant fluid from the container, but permits inward passage of air so that, during engine and drive unit cooling, lubricant can be sucked back into the system through the drive housings. The cap may be provided with a lubricant level warning device (41-43; 45-47) which extends downwardly into the container. In another embodiment, the warning device is spaced from the cap and extends upwardly into the container. In another embodiment, the container may be provided with a spring loaded diaphragm (53) which is movably responsive to the lubricant pressure within the stern drive unit.
