Abstract
A gear case assembly for a marine propulsion system has a gear case, a driveshaft, a propeller shaft, and a transmission chamber. A driveshaft passage fluidly connects to the transmission chamber. A lubricant return passage fluidly connects to the transmission chamber and the driveshaft passage. A pump is driven by the driveshaft. A first lubricant filling port fluidly communicates one of the lubricant return passage and the driveshaft passage with an exterior of the gear case. A second lubricant filling port fluidly communicates one of the lubricant return passage and the transmission chamber with the exterior of the gear case. First and second plugs are selectively disposed in the first and second lubricant filling ports respectively. A check valve is disposed in the lubricant return passage between the first and second lubricant filling ports. The check valve prevents lubricant to flow through the check valve away from the transmission chamber.
