A propulsion system for a hydrofoil, planing or semi-planing sea-going vessel having a hull having a port pump water inlet formed therethrough on its port side, a starboard pump water inlet formed therethrough on its starboard side and first, second and third outlets formed therethrough, comprises a booster first stage system in the hull coupled to and driven by the motors. The booster first stage system comprises a first axial water jet pump at the port pump water inlet and a second axial water jet pump at the starboard pump water inlet. A second stage water jet system in the hull aft of the first stage system comprises a third axial water jet pump functioning as a turbocharger. Water ducts are provided in the hull from each of the pump water inlets through the corresponding one of the first and second pumps to the corresponding one of the first and second water outlets, from each of the pump water inlets through the corresponding one of the first and second pumps and thence through the third pump, to the third water outlet, and from each of the pump water inlets through the third pump to the third water outlet, bypassing the first and second pumps. A control system selectively directs a water flow through the first and second pumps simultaneously, through the first pump solely, through the second pump solely, through the third pump solely, through the first and second pumps and the third pump simultaneously, through the first pump and the third pump simultaneously and through the second pump and the third pump simultaneously.
