Abstract

An outboard marine drive (10) has a powerhead (20) including an internal combustion engine (22), an adaptor plate (24) mounted to the engine, and a lower gearcase (26) including a torpedo housing (28) rotatably mounting a propeller (30), wherein the lower gearcase is directly mounted to the adaptor plate without a driveshaft housing therebetween. An enclosing cowl (68) has left and right sidewalls (72 and 74), a back wall (76), and a top wall (78), and is open to the bottom (80) and open to the front (82) facing the boat. The adaptor plate is mounted to the bottom of the engine and closes the open bottom of the cowl in a horizontal plane, and the engine has left and right sides (84 and 86) closing the open front of the cowl in a vertical plane. The engine has a pair of upper and lower vertically spaced mounting arms (88 and 90) integrally cast with the engine crankcase (92) and extending forwardly toward the boat and journaled respectively to upper and lower ends (100 and 102) of a king pin (98) of a swivel bracket (94).
