摘要： An air intake silencer includes an air inlet pipe and at least one tuning tube in fluid communication with the air inlet pipe. A first length and second length of the air inlet pipe and the tuning tube, respectively, are selected to produce one-half wavelength cancellation of a selected frequency of engine noise. A plurality of tuning tubes located in a wrap-around relationship with on another may tune different frequencies of noise in a compact silencing unit. The air inlet pipe and tuning tube may be integrally formed into an air intake manifold that silences one or more engine air intake inlets, and the air intake silencer may be integrated into a motor cover.

摘要： A vibration absorbing steering device for an outboard motor having a swivel bracket constructed and arranged for mounting to a transom bracket of a boat and defining a vertical passageway includes a tubular pivot shaft being pivotally engaged in the passageway, an engine mount bracket designed to mount the engine for rotation with the pivot shaft, and a vibration absorbing torque tube for absorbing vibration generated by the engine. The torque tube is vertically disposed within the tubular pivot shaft and is secured at one end to the pivot shaft. A tiller arm has a pivot end attached to the upper end of the torque tube so that the tiller arm is connected to the engine mount bracket through the torque tube, and the torque tube absorbs vibration from the engine which would normally be transmitted through the tiller arm to the operator. In addition to absorbing engine vibration, the present device also permits positive steering control of the motor by manipulation of the tiller arm.
