Abstract: A steering system for boats includes a control member of the steering wheel type, lever type or the like connected to a driving shaft of a transmission composed of at least two transmission elements dynamically engaged one with the other, of which one is an input and the other one an output elements. The output element drives a member transferring the motion of the control member to an operating unit, such that a movement/rotation of the control member is transmitted to the transfer member through such transmission. Moreover, at least the input element is produced from a material obtained by a sintering process.
