A lubrication system is provided that allows delivery, and preferably regulated delivery, of lubricant to a coupling between a crankshaft and the driveshaft of, for example, an outboard motor. The lubrication system includes a passageway through which lubricant flows, and preferably a flow restrictor regulates the amount of lubricant delivered through the passageway. In one mode, the passageway is generally formed vertically through the central axis of a vertically oriented crankshaft and extends between the crankcase chamber and the coupling. Lubricant, such as crankcase oil, is able to flow through the passageway and onto the coupling. One or more seals preferably inhibit lubricant from flowing beyond the coupling.
