An hydraulic power system for a boat comprising a marine thruster assembly. A structure is for mounting the marine thruster assembly to an exterior surface of a transom on the boat. A first hydraulic operative facility is for propelling the marine thruster assembly, so that the boat can travel in a body of water. A second hydraulic operative facility is for steering the marine thruster assembly, so that the boat can be directed on a course in the body of water. A third hydraulic operative facility is for lifting the marine thruster assembly out of the body of water for inspection and repair when needed.
