Abstract

To provide a marine drive shaft-bearing structure capable of simply filling grease without an effort and at a reduced cost. A marine drive shaft-bearing structure includes a bearing body disposed between an engine and an impeller for propulsion. Front and rear bearing members are received in a bearing chamber within the bearing body so as to rotatably support a drive shaft which connects the engine with the impeller. A grease filling portion is adapted to fill grease into the bearing chamber. The grease filling portion includes a grease filling port formed in the bearing body so as to communicate with the bearing chamber and a grease tank for storing the grease and for being detachably attached to the grease filling port.
