1. A method for controlling a water jet propulsion device for the propulsion of a marine vessel, the water jet propulsion device comprising a conduit extending between an inlet and an outlet, an impeller in the conduit, and a mechanical power provider arranged to deliver power to the impeller, the method comprising:
receiving a plurality of thrust commands; and
controlling a thrust level of the water jet propulsion device in dependence of the thrust commands,
wherein controlling the thrust level comprises adjusting a position of a deflector arranged to deflect water flowing out of the outlet,
characterised by coordinating the adjustment of the position of the deflector with a level of engagement of a clutch, arranged to adjust the delivery of power from the power provider to the impeller, so that the thrust level is substantially continuous in a thrust command domain.
