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.

For use with a marine stern drive mounted to the transom (2) of a boat (3), and with said stern drive having a lubricant-filled drive shaft housing (10) visual lubricant inspection means adapted for mounting inboard of a boat and in fluid communication with a connected drive shaft housing, said inspection means comprising, in combination: (a) a transparent reservoir forming a lubricant-receiving chamber, (b) means for fluidly connecting said reservoir to the drive shaft housing of a stern drive, (c) lubricant level detecting means (74-76) supported in said reservoir for automatically warning of the existence of an undesirable level of lubricant within said reservoir, (d) a removable cap (60) mounted to said reservoir, and with said cap having a central through passage (61), an inner wall (66) and an outer cap wall, (e) an annular recess (62) disposed on said inner wall, (f) a vent passage (63) extending transversely outwardly through said cap and communicating between said annular recess and the atmosphere, (g) a further recess (68) disposed in said outer cap wall, (h) and a one-way umbrella check valve (64) mounted in said through passage (61), (i) said umbrella check valve having a large sealing member (65) sealing against said inner wall (66) and covering said annular recess (62), (j) and said umbrella check valve having a stop member (67) resting against said further recess (68) in said outer cap wall, (k) said umbrella check valve providing means to prevent air discharge from said lubricant-receiving chamber and outwardly through said annular recess (62) and said transverse vent passage (63) during running of a connected stern drive, while permitting air inflow through said transverse vent passage and annular recess to said lubricant-receiving chamber when a connected stern drive is at rest.
