They help prevent gear lube from leaking out and water from seeping into the gear case, which could otherwise cause serious damage to the engine and its components.
To use these drain plugs, you simply pump oil into the bottom plug until it flows out of the top plug. After ensuring proper lubrication, you screw the top plug in tightly, and then quickly secure the bottom plug to minimize oil loss. This straightforward process simplifies routine maintenance tasks for your boat's lower unit.
