MARINE PROPULSION SYSTEM

Abstract: a marine propulsion system for a marine vessel having a vessel speed, has an electric motor providing torque and rotational speed, the torque and rotational speed being motor data of the electric motor. a drive unit is pivotable in relation to the marine vessel, the drive unit being powered by the electric motor. a trim arrangement adjusts a trim angle of the drive unit. a control unit being is connected with the electric motor and the trim arrangement, the control unit receives motor data from the electric motor and trim data from the trim arrangement. the control unit has a processing circuitry for comparing the motor data with the trim data. the control unit is configured to actively adjust the trim angle of the drive unit based on the motor data whereby an energy consumption of the electric motor at the same vessel speed can be optimized at any condition of the marine vessel.
