ABSTRACT:
A two-cycle engine for small watercraft for driving a propeller shaft includes a water discharge passageway located in the crankcase of the engine for communicating the crank chamber with outside to discharge water from the crank chamber. A closing member having a manually operated portion for opening and closing the closing member is fitted in the water discharge passageway. When it is desired to discharge water from the crank chamber, the manually operated portion is manipulated to open the closing member, so that the water can be discharged therefrom to outside via the water discharge passageway without requiring to remove the engine from the engine room.
