ABSTRACT:
A self-contained hydraulic thruster for vessel. The hydraulic thruster incorporates an elevated helm platform mounted to a base having reinforced base feet, and a hydraulic fluid reservoir mounted on the helm platform. The elevation of the hydraulic fluid reservoir facilitates flow of hydraulic fluid to a hydraulic power pack mounted on the base. A lower unit mounting tube is attached to the base, and at least one lower unit is mounted at an end of the lower unit mounting tube, laterally offset from the helm platform, so that when the lower unit is retracted and tilted up, it lies on one side of the platform, and the platform doesn't interfere with retraction and tilting of the lower unit. Lower units are pivotably mounted in lower unit housings with lower unit bushings, and steering is provided by a steering motor through an overhung load adaptor to a drive gear.
