    摘要： A propeller shield to selectively shield rotating blades of a propeller. The propeller shield may include a shield element for placement adjacent to the propeller blades. The shield element may include multiple gates configured to open in response to water flow generated by the propeller. The gates may be configured to open away from the propeller in response to a forward movement of the boat, and to close towards the propeller in response to cessation of the forward movement.

    摘要： A lower unit for a marine propulsion device includes a gearcase housing defined along a longitudinal center axis between a fore end and an aft end. A propulsor shaft extends through the gearcase housing along the longitudinal axis. A driveshaft extends non-parallel to the propulsor shaft and rotates in a direction of rotation when powered by an engine. The driveshaft is coupled in torque-transmitting relationship with the propulsor shaft. A skeg projects from a bottom surface of the gearcase housing proximate at least the aft end thereof. The skeg or the gearcase housing is cambered such that a moment acting in a direction opposite the driveshaft's direction of rotation is induced on the skeg or the gearcase housing as the lower unit moves through water. A marine propulsion device is also disclosed.

    摘要： A ship is disclosed which can include a hull, at least one propulsion unit having a propulsion engine, transmission, at least one propeller connected via the transmission to the propulsion engine, and an oscillation sensor situated in a vicinity of the at least one propeller in order to sense cavitation of the at least one propeller. A control unit can control the propulsion engine, the oscillation sensor being connected to the control unit, whereby the output signal of the oscillation sensor is analyzed in the control unit to detect and indicate that a worse degree cavitation is emerging on a display unit at the navigation bridge and/or regulate the rotation speed and/or the power of the propulsion engine.

    摘要： An assembly (10) is provided for mounting a hydrofoil, trolling plate or trolling motor (or other accessory) on the anti-ventilation plate (14) of a sterndrive or outboard motor (16) without the need to modify the plate or motor. The assembly (10) has lower and upper elements (20, 22) which are secured about the plate (14) by bolts (34). The upper element (22) has a bolt pattern (40) to mount the hydrofoil or other device. Grip devices (50) can be mounted on the lower element (20) that are adjusted to grip the edges of the plate (14). A catch (60) mounted on the lower element (20) can be engaged in the trim tab or anode recess.
