The invention provides a water jet system with higher efficiency and better steering. The water jet system uses cantilever bars for an inlet grating, to prevent blockage. The water jet system also uses an elliptical impeller shaft housing to reduce turbulence and snagging of debris by the rotating impeller shaft. The water jet system uses impeller blades with a curved cross section that curves towards the direction of forward rotation. The water jet system uses U-shaped flanges mounted to the outlet of the water jet to provide steering.

The invention provides an amphibious vehicle that integrates suspension fairing with a movable bow vane. This integration, allows the suspension fairings to be stored between the bow vane and the hull of the vehicle during land use and to be automatically deployed during water use. The suspension fairing uses a deployment system connected with the bow vane deployment system, so that they are deployed and retracted as an integral system.

A transom flap can be deployed from the transom of an amphibious vehicle when the vessel is water borne. The transom flap is pivotally mounted and can be extended to extend into a position relatively acute to the transom of the vessel the transom flap can be extended to impinge the propulsion jet of a jet propulsion drive system of the vessel or it can be deployed to extend out of the jet stream but at a less acute angle such that it will be helpful in trim adjustment of the vessel at speed.
