ABSTRACT:
A marine propulsion unit utilizing a turbine engine is provided as a drop-in module. The propulsion unit includes a base which forms a part of the hull. The propulsion unit includes a drive unit which is mounted to the engine. Both the engine and the drive unit are moved with respect to the hull to change the angle of the propeller with respect to the hull. A hydraulic resistance system is provided to provide resistance to a turbine engine when in an idle condition. An auxiliary power transfer is provided to power an auxiliary genset and power unit. A main electrical power unit having an auxiliary engine is also connected to the power transfer unit. The auxiliary engine may be used to drive the vessel at low speeds and maneuvering conditions. One of the main engines may be used to drive both of the shafts through the power transfer unit.
