A hydraulic steering system for a watercraft has first and second hydraulic steering actuators for steering first and second outdrives respectively, at least one hydraulic pump selectively supplying hydraulic pressure to at least one of the first and second actuators, a steering controller operatively connected to the at least one pump, a hydraulic helm selectively supplying hydraulic pressure to the first and second actuators, an auxiliary steering input device connected to the controller, and at least one mode selection valve having first and second mode positions for steering the watercraft in first and second steering modes respectively. In the first steering mode, the hydraulic helm is hydraulically connected to the first and second actuators. In the second steering mode, the hydraulic helm is hydraulically disconnected from the first and second actuators. A watercraft having the steering system and a method for steering a watercraft are also disclosed.

An outboard engine has a bracket. A drive unit mounted thereto is pivotable about a steering axis with respect thereto by a steering actuator. A motor operatively connected to the steering actuator is mounted to the bracket and rotationally fixed with respect thereto about the steering axis. A control module includes a motor drive electrically connected to the motor and configured to be connected to a power source. An electrically conductive thermal element is electrically connected to the motor. A temperature of the thermal element is indicative of a temperature of the motor. A controller is configured to obtain the temperature of the thermal element and to control power delivered to the motor via the motor drive based at least in part on the temperature of the thermal element. The controller and the thermal element are mounted to the drive unit and pivotable therewith about the steering axis.
摘要:
A cowling for housing an outboard engine. The cowling includes a plurality of walls defining at least in part an engine compartment. An engine compartment inlet, in fluid communication with the engine compartment, is defined at least in part by at least one of the plurality of walls. A hydrophobic mesh member disposed across the inlet is adapted to prevent at least a portion of a water content of an airflow flowing to the engine compartment via the engine compartment inlet from entering the engine compartment. An outboard engine having the cowling is also disclosed.

An outboard engine has a cowling defining an engine compartment, an internal combustion engine disposed at least in part in the engine compartment, a driveshaft operatively connected to the internal combustion engine, and one of a propeller and an impeller operatively connected to the driveshaft. The one of the propeller and the impeller rotates about an axis that is angled relative to the driveshaft. A device is disposed inside the engine compartment. A box is disposed outside the engine compartment and is operatively connected to the engine compartment. A line has a portion disposed inside the box and an end operatively connected to the device. An outboard engine having a box disposed outside the engine compartment and operatively connected to the bracket is also disclosed. A watercraft having the outboard engine is also disclosed.

A hydraulic system for a marine engine has a fluid reservoir, a bi-directional pump, a valve assembly, and a hydraulic actuator. The valve assembly includes: first and fourth apertures fluidly communicating with the pump, second and third apertures fluidly communicating with the actuator, and a fifth aperture fluidly communicating with the fluid reservoir. Operating the pump to supply hydraulic fluid to the first aperture causes hydraulic fluid to flow from the pump to the actuator and from the actuator to the fluid reservoir, and causes the actuator to move in a first actuator direction. Operating the pump to supply hydraulic fluid to the fourth aperture causes hydraulic fluid to flow from the pump to the actuator and from the actuator to the pump, and causes the actuator to move in a second actuator direction opposite the first actuator direction.
摘要:
A crankshaft has a receiving platform for catching lubricant dropping from a main bearing assembly. The receiving platform has at least one wall disposed thereon. The wall has one point that is the furthest from the rotational axis of the crankshaft. One channel is defined in the platform and has an inlet disposed close to the point of the wall that is furthest from the rotational axis of the crankshaft. The channel has an outlet in the vicinity of a connecting rod bearing assembly, so that lubricant dropped on the receiving platform will flow to the connecting rod bearing assembly.

A propeller assembly is disclosed, comprising propeller blades pivotably mounted on a propeller hub. A cam follower is disposed on each propeller blade. A cam is movable between a first position, a second position and a third position. Recesses formed in the cam have a first segment, a second segment and a third segment, oriented at first, second and third angles. The first segment is oriented at a first angle relative to the central axis. The cam followers engage the first segment of the recesses when the cam moves between first and second positions to vary the pitch of the propeller blades between a first pitch and a second pitch. The cam followers engage the second segment of the recesses when the cam moves between second and third positions to vary the pitch of the propeller blades between the second pitch and a third pitch.
