1. A self-contained, remote controlled lockable marine latch comprising a hollow housing formed by walls, a pivotable catch stem, a bolt operable to prevent pivotable movement of the stem, and an electrically driven actuator all contained in the housing, the housing being arranged to exclude water and being substantially splash proof, the stem having a portion extending through a hole in a wall of the housing, a seal surrounding the stem portion extending through said hole to exclude water from entering the housing, the bolt in the housing being movable between a locked position and an unlocked position, the bolt in the locked position preventing the stem from pivoting out of a latched position and in the unlocked position, enabling the stem to move to an unlatched position, the bolt being driven by the actuator through a rack and pinion gear, a lock plug operable with a key, the lock plug having a lug disposed in a clearance hole in the bolt being arranged to override the position of the bolt determined by said actuator. 2. A lockable latch as set forth in claim 1, wherein said actuator is bi-directional. 3. A lockable latch as set forth in claim 2, wherein said actuator is a rotary electric motor. 4. A lockable latch as set forth in claim 3, wherein said rotary motor drives the rack through the pinion gear in two directions. 5. A lockable latch as set forth in claim 1, wherein said housing walls include a cylindrical skirt enabling the housing to be mounted in a circular hole in a panel. 6. A lockable latch as set forth in claim 5, wherein said cylindrical skirt is externally threaded and including a nut threadable onto said threaded skirt to effect mounting of said housing on a panel. 7. A lockable latch for marine use including a splash proof housing, a stem pivotally mounted on the housing, a latch carried on the stem externally of the housing, a handle external of the housing connected to the stem in a manner wherein the handle can be manipulated to pivot the stem and move the cam between a latching position and an unlatching position, a bolt within the housing movable between a lock position where it restrains pivoting of the stem, and an unlocked position wherein it permits pivoting of the stem, an electrically operated actuator in the housing for selectively moving the bolt between said lock and unlock positions, the bolt being driven by the actuator through a rack and pinion gear and a key operated lug disposed in a clearance hole in the bolt for manually moving said bolt between said lock and unlock positions independently of the position established by the actuator. 8. A lockable latch as set forth in claim 7, wherein said actuator is a rotary reversible electric DC motor. 9. A lockable latch as set forth in claim 8, wherein said motor is connected to said bolt through a gear train. 10. A lockable latch as set forth in claim 9, wherein said gear train is arranged to be back-driven by said lug. 11. A lockable latch as set forth in claim 10, wherein said gear train includes a pair of meshing bevel gears.
