A marine steering arrangement wherein each of the starboard steering switch and port steering switch connected to a power source is closed upon receipt of an actuating signal resulting from a difference between an order signal of a rudder angle and an actual signal of a rudder angle, so as to conduct power to a rudder driving mechanism, rotating the rudder to the order rudder angle position within an allowable extent of the rudder angle, is provided with an improvement which further comprises at least one limit switch for shutting off the power source to stop any further rotation of the rudder beyond either of the rudder angle limits.
