A marine electric power steering system includes an actuator assembly, a power steering module, and a cable assembly. The actuator assembly includes an actuator assembly input and an actuator assembly output. The actuator assembly input is operatively coupled to a steering shaft. The power steering module includes a power steering module input that is operatively coupled to the actuator assembly output and a power steering module output. The cable assembly is operatively coupled to the actuator assembly output and the power steering module input.
