Abstract: There is provided mechanisms for controlling movement of a propeller shaft on a vessel. A controller includes processing circuitry. The processing circuitry is configured to cause the controller to detect movement of the propeller shaft by determining a signature of a sustained oscillation of the propeller shaft. The processing circuitry is configured to cause the controller to control movement of the propeller shaft according to the determined signature.

Abstract: A propeller for a boat includes a propeller shaft having a shaft hole, a shaft sleeve mounted in the shaft hole of the propeller shaft and provided with a metal core with a through hole for insertion of a driving shaft of the boat, and a shock-absorbing member covering an outer surface of the metal and having an outer surface contacted with an inner surface of the propeller shaft that surrounds the shaft hole; and a lock unit mounted on the driving shaft for fixing the driving shaft in the through hole of the shaft sleeve, so that the propeller is rotatable by the driving shaft. When the propeller bumps hard things during rotation to result in vibration to the propeller, the shock-absorbing member can absorb the vibration so as to protect the driving shaft from damage.

Abstract: A shock absorbing device for a watercraft propeller is provided that can include an outer tube unitarily formed with blades of a propeller. An inner tube can be coupled with a propeller shaft. An intermediate tube can be positioned between the outer tube and the inner tube. A first damping means can be placed between the intermediate tube and the outer tube. A second damping means can be placed between the intermediate tube and the inner tube. One of the damping means can include a rubber damper interposed between the inner tube and the intermediate tube, and an engaging means for limiting an angle range in which the inner tube and the intermediate tube can be rotatable relative to each other to a predetermined angle range. The rubber damper can have a spring constant with which elastic deformation thereof begins at a moment that the propeller shaft initiates its rotation. The other damping means includes a torque limiter (tolerance rings 16) having a circumferential surface that slips against frictional resistance.

Abstract: An arrangement for attenuating vibrations of blades attached to a peripheral surface of a rotor of an axial turbine. A through hole is formed in each rotor blade in a generally thickness direction of the blade so that the through holes in combination define a single annular passage near a rotor surface when all of the rotor blades are attached to the rotor. A wire is provided to extend through the aligned through holes. Thus, the wire frictionally contacts the through holes when the blades are caused to vibrate due to a gas pressure and a centrifugal force generated upon operation of the axial turbine. Friction contact between the wire and the through holes attenuates vibrations of the blades.

Abstract: An outboard motor and improved torsional vibration damper adapted to be supported on the lower end of the output shaft of the engine of the outboard motor. The torsional vibration damper is formed with an oil receiving groove in which oil and fuel which may drain from the engine can collect without affecting the elastomeric sleeve. A drain hole permits the oil to be relieved from the oil collecting groove and this drain hole is threaded so as to receive a puller for pulling the torsional damper from the engine output shaft.

Abstract: When there is relative movement, at a speed above a critical value, between the trailing edge of a body, such as a hydrofoil or aerofoil section, and a fluid, the fluid flow tends to form a pattern of discrete swirling vortices. Vortex shedding at each side of the trailing edge alternately can cause resonance or "singing" of the section. The effect of this phenomenon is reduced by forming contiguous triangular flat-faced notches in the major surfaces of the section, adjacent the trailing edge, but leaving the profile of the leading edge substantially undistrubed. The notches in one major surface are preferably staggered relative to those in the other major surface.
