Abstract
A watercraft has a hull, a deck, an engine compartment, an engine disposed in the engine compartment, a steering assembly, a jet pump, a venturi connected to the jet pump, a variable trim system (VTS) support rotationally mounted relative to the venturi about a VTS axis, a steering nozzle rotationally mounted to the VTS support about a steering axis, and a gate rotationally mounted relative to the venturi about a gate axis. The gate is operatively connected to the VTS support such that rotation of the gate about the gate axis results in rotation of the VTS support about the VTS axis. An actuator is operatively connected to the gate to rotate the gate about the gate axis. The gate is operatively connected between the actuator and the VTS support. A jet propulsion system and a variable trim system and gate assembly are also disclosed.
