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.

Abstract: A stabilizing fin assembly for use with a watercraft includes a mounting structure, a stabilizing fin structure, and a releasable securement structure. The mounting structure is fixedly attached to a side portion of a hull of a watercraft. The stabilizing fin structure is removably mounted to the mounting structure. When the mounting structure is fixedly attached to the hull, the stabilizing fin structure is disposed externally of the hull and adjacent the side portion of the hull in an operative position wherein at least a portion of the stabilizing fin structure extends into a body of water while the watercraft is in a normal operative position. The releasable securement structure is disposed in a releasably secured position on the hull. The stabilizing fin structure facilitates removal and replacement of the stabilizing fin structure without requiring access to the interior of the watercraft.
