Abstract: A system for adjusting the rotational timing between driveshafts rotated by an output shaft. The system includes a flange coupler configured to be coupled to a first of the driveshafts to prevent rotation therebetween. The flange coupler defines openings therein. A coupler input gear defines openings therein and is configured to rotatably mesh with a second input gear coupled to a second of the driveshafts. Fasteners are configured to the extend through the openings in the flange coupler and the openings in the coupler input gear to rotationally fix the flange coupler and the coupler input gear, which are fixable at multiple rotational orientations therebetween. The rotational timing between the driveshafts is adjustable by rotating the coupler input gear into different orientations of the multiple rotational orientations relative to the flange coupler prior to fixing the flange coupler to the coupler input gear.

Abstract: An outboard motor has a powerhead; a supporting cradle supporting the powerhead, the supporting cradle having port and starboard sides extending alongside opposite sides of the outboard motor; a resilient mount coupling the powerhead to the supporting cradle and being configured to absorb vibrations of the powerhead; and a tie bar mounting bracket having a head portion located aftwardly of the supporting cradle and further having port and starboard arms extending forwardly from the head portion alongside the opposite sides of the outboard motor and being coupled to the port and starboard sides of the supporting cradle, respectively. A cooling system conveys cooling water through the outboard motor and has a telltale outlet that discharges cooling water through the tie bar mounting apparatus.

Abstract: A transmission is for a marine drive. The transmission comprises an input shaft that is caused to rotate by the marine drive and an output shaft that is caused to rotate by the input shaft. The input shaft and output shaft are operatively connected to each other such that forward rotation of the input shaft causes forward rotation of the output shaft when the transmission is shifted into a forward gear, and such that forward rotation of the input shaft causes reverse rotation of the output shaft when the transmission is shifted into a reverse gear. A planetary gearset operatively couples the input shaft to the output shaft only when the transmission is shifted into the reverse gear.

Abstract: A transmission for a marine propulsion system uses a cone clutch in such a way that, when in a forward gear position, torque is transmitted from an input shaft, or driving shaft, to an output shaft, or driven shaft, solely through the cone clutch. When in forward gear position, driving torque between the driving and driven shafts is not transmitted through any gear teeth. When in reverse gear position, torque is transmitted through an assembly of the bevel gears.

Abstract: A marine propulsion system is provided with a transom housing, an intermediate housing, and a drive shaft housing which are rotatable relative to each other. A gearcase is provided which is rotatable, about a drive shaft axis, relative to the drive shaft housing. By selectively rotating the housings relative to each other, the gearcase can be raised or lowered without changing the angle of the drive shaft relative to a horizontal plane. In addition, the gearcase can be trimmed or tilted to a wide variety of angles relative to the transom housing 70.

Abstract: A marine propulsion system is provided with a drive unit that is attachable to a transom of a marine vessel and provided with steering cylinder assemblies and trimming cylinder assemblies which are connected to a common location on a structural member, such as a gimbal ring. This arrangement improves the geometric relationship between the steering and trimming functions. In addition, the hydraulic steering system is provided with pressure relief valves that are located at the transom of the marine vessel in order to shorten the distance of the hydraulic conduits extending between the pressure relief valves and the steering cylinders.
