Abstract
A self-contained hydraulic thruster for vessel. A power pack is mounted on a forward end of a base, and a helm platform is mounted on an aft end of the base at a substantial height above the base. A reservoir in communication with the power pack is mounted on the helm platform, thus facilitating hydraulic fluid flow from the reservoir to the power pack, and also rendering the hydraulic system self-priming. At least one lower unit is tiltably mounted to the base aft end, laterally offset from the helm platform. Due to the lateral offset between the lower unit(s) and the helm platform, interference between the lower unit(s) and the helm platform is avoided when the lower unit(s) is retracted and tilted up for transportation, storage, or maintenance.
