Jet propulsion trim and reverse system

A watercraft has a jet pump and a venturi. A variable trim system (VTS) support and a reverse gate are rotationally mounted relative to the venturi. A steering nozzle is rotationally mounted to the VTS support. A rotary actuator has an output portion operatively connected to at least one of the VTS...

More Information
Summary:A watercraft has a jet pump and a venturi. A variable trim system (VTS) support and a reverse gate are rotationally mounted relative to the venturi. A steering nozzle is rotationally mounted to the VTS support. A rotary actuator has an output portion operatively connected to at least one of the VTS support and the reverse gate. Rotation of the output portion between a first angle and a second angle causes a rotation of the VTS support while the reverse gate remains in a stowed position relative to the steering nozzle. Rotation of the output portion between the second angle and a third angle causes a rotation of the reverse gate between the stowed position and a second position while the VTS support remains in a fixed position. A jet propulsion system and a method of operating a jet propulsion system are also disclosed.
