ABSTRACT:
The present invention pertains to an emergency propulsion system for both motor powered and sailing vessels which have a single propeller shaft. This emergency system may be used with inboard engines or with a sailing vessel that has a small engine used for moving said vessel and/or docking. While and when under way engine failure may be experienced. Such failure is usually very inconvenient to the user of the boat. Many times such failure can and does become a serious matter. The present hydraulic propulsion system of this invention is intended to provide a "get home" drive for trawlers or sailing vessels using a single engine. A small diesel engine that is used to provide electrical generation is also selectively employed to turn a hydrostatic pump and then through a fluid connected means drives a hydrostatic motor which drives a V-belt to the propeller shaft. The hydrostatic pump is operatively driven by the diesel engine but the motor is operatively connected to the propeller shaft only after the disabled main engine is disconnected from the propeller shaft.
