PROBLEM TO BE SOLVED: To use only one set of controlling gears and one control lever even when a plurality of water jet propulsion devices are installed. SOLUTION: The propulsion equipment comprises a water jet propulsion device with a water jet pump driven by an engine and three buckets whose reverser angle is adjusted by an actuator, one set of controlling gears 19 for controlling an arbitrary number and arbitrary combination of water jet propulsion devices, one control lever 20 for controlling the controlling gears 19, a selection switch 21 for changing the control system of the controlling gears 19 when a first water jet propulsion device is driven, a selection switch 22 for changing the control system of the controlling gears 19 when a second water jet propulsion device is driven, and a selection switch 23 for changing the control system of the controlling gears 19 when a third water jet propulsion device is driven.
