摘要： A marine drive has an internal combustion engine that rotates a propulsor shaft that is operatively coupled to a propulsor to impart a propulsive thrust in water. The marine drive has a gearcase housing having an upper portion above a lower portion, the lower portion supporting the propulsor shaft. An exhaust passage in the gearcase housing is configured to convey exhaust gas from the internal combustion engine. An exhaust outlet on the upper portion of the gearcase housing is configured to discharge the exhaust gas from the exhaust passage to the water. The exhaust outlet faces the propulsor so that the exhaust gas is discharged into the water and towards the propulsor so as to aerate the water encountered by the propulsor.

摘要： A system for rotating a propeller shaft within a gearcase via a driveshaft. A stub shaft is rotatable within the gearcase. A forward gear is rotatably coupled to the stub shaft. The forward gear is rotatable by the driveshaft and is engageable to become rotatably fixed to the stub shaft such that rotating the driveshaft rotates the stub shaft. A shock absorbing coupler is positioned within the gearcase. The shock absorbing coupler couples the stub shaft to the propeller shaft and is torsional such that shock is absorbable between the propeller shaft and the driveshaft.

摘要： An outboard motor comprises an engine; an input driveshaft that is caused to rotate by the engine; an output driveshaft that extends parallel to and is laterally spaced apart from the input driveshaft; and a transmission that operatively connects the input driveshaft to the output driveshaft such that rotation of the input driveshaft causes rotation of the output driveshaft. The transmission is positionable into a forward gear in which forward rotation of the input driveshaft causes forward rotation of the output driveshaft, a reverse gear in which forward rotation of the input driveshaft causes reverse rotation of the output driveshaft, and neutral wherein forward rotation of the driveshaft does not cause rotation of the output driveshaft.

摘要： An outboard marine engine comprises an internal combustion engine; a lower gearcase, a set of gears disposed in the lower gearcase, the set of gears being configured to transfer power from the internal combustion engine to drive a propulsor to generate a thrust on the outboard marine engine, and a dipstick that extends into the lower gearcase. The dipstick is removable from the lower gearcase and configured to indicate a level of lubrication in the lower gearcase.

摘要： A system for rotating an inner propeller shaft within a gearcase via a driveshaft. The system includes a stub shaft that extends between forward and aft ends and is rotatable within the gearcase. A forward gear is rotatably coupled to the stub shaft, where the forward gear meshes with the driveshaft and is engageable to become rotatably fixed to the stub shaft such that rotating the driveshaft rotates the stub shaft. A shock absorbing coupler is positioned within the gearcase, where the coupler has forward and aft ends, where the forward end of the coupler is engageable with the aft end of the stub shaft, and where the aft end of the coupler engageable with the inner propeller shaft. The coupler is torsional between the forward and aft ends such that shock is absorbable between the inner propeller shaft and the driveshaft.

摘要： An outboard motor having an internal combustion engine that causes rotation of a driveshaft and a planetary transmission that operatively connects the driveshaft to a transmission output shaft, the planetary transmission being operable in a forward gear in which forward rotation of the driveshaft causes forward rotation of the output shaft, a reverse gear in which forward rotation of the driveshaft causes reverse rotation of the output shaft, and a neutral gear in which rotation of the driveshaft does not cause rotation of the output shaft, a band brake configured to shift the planetary transmission amongst the forward gear, neutral gear, and reverse gear, and a hydraulic actuator configured to actuate the band brake.
