The Evoltech Energymatic is a variable-pitch propeller designed for hydraulic transmissions and energy generation.1:03 Hydraulic transmissions often fail to lock the propeller shaft, preventing standard propellers from feathering correctly.1:31 The Energymatic incorporates an internal spring mechanism that automatically forces the blades into a feathered position when the engine torque ceases, eliminating the need for a manual shaft lock.1:43

The propeller also functions as a hydro-generator while the vessel is under sail.1:51 By engaging reverse gear, the blades lock in an open position, allowing the water flow to spin the propeller and generate electricity.1:43 This feature supports both electric propulsion systems and internal combustion engines equipped with shaft-driven alternators.1:52 The Energymatic received an award for green innovation at the Newport boat show.2:54
