Abstract
A self-contained hydraulic thruster for vessel. The hydraulic thruster incorporates at least one lower unit housing tiltably attached to a base at a base lower unit cutout laterally offset from a helm platform. Tilt actuator(s) disposed entirely above a base upper surface tilt each lower unit up or down relative to the base. Two positive down-tilt means are disclosed: housing arm lower edge(s) resting on the base upper surface, and also down stop tab(s) extending from a base lower unit cutout wall into the base lower unit cutout against which a forward housing wall edge butts when the housing is tilted fully down. In addition, base bores through the base are disclosed, and pins which slidably fit into respective base bores and extend downwards from the base to serve as positioning stops when installing the hydraulic thruster on a vessel.
