Jet-powered boat control system, comprising:at least one water jet propulsion group, such as a turbine or the like;an ejection nozzle of the water jet connected to the exit of that water jet propulsion group, which nozzle is oriented in such a way as to direct the water jet essentially at least in the longitudinal direction of the vessel;a jet deflector to change the flow direction of at least part of the water jet coming out of the nozzle from the direction essentially parallel to the longitudinal axis of the vessel and according to a direction from the bow to the stern of the boat;said deflector being controllable in such a way as to progressively adjust the part of the water jet diverted from that direction essentially parallel to the longitudinal axis of the boat and according to a direction from the bow to the stern of the boat, to determine a neutral thrust condition in which the boat is stationary, thrusting forward with variable speed and thrusting backwards with at least a predetermined speed;a control member of the deflector position to alternately move in one of those conditions;a setting member of said deflector so as to adjust the deflector to get the neutral thrust condition, the said deflector being provided with a predetermined and pre-set neutral thrust positioncharacterized in thatsuch system includes a control member of said deflector in the preset position of neutral thrust, canceling any subsequent customization settings.
