A marine drive (2) having a lower gearcase (4) with a torpedo housing (10) having an internal lubricant-containing cavity (26) has a removable drain plug (50) and drain plug hole (52) at a location away from the exterior hydrodynamic surface (46) of the torpedo housing along which water flows, to prevent cavitation burns on the torpedo housing and the propeller (24), and to aid in eliminating propeller ventilation.
