A steering system for a marine vessel, which includes a helm with a rotatable steering shaft and a sensor that senses angular movement of the steering shaft. An electromagnetic actuator actuates a stop mechanism to releasably engage the steering shaft. A microcontroller processes a steering sensor signal and causes the actuator to actuate the stop mechanism to fully engage the steering shaft when the sensor senses that the steering shaft has reached a hardstop position. This prevents rotation of the steering shaft towards the hardstop position, while allowing rotational play between the steering shaft and the stop mechanism away from the hardstop position. A driver applies a reserve polarity pulse to the electromagnetic actuator when the stop mechanism is fully engaged with the steering shaft and the steering shaft is rotated, as permitted by the rotational play, in the second rotational direction.
