A water jet pump for water borne craft that can have an 'outboard' or a 'stern- drive' configuration. The stator-gearbox housing of the jet pump may have an outboard power-head attached to its upper surface or alternatively a right angle drive can be attached thus permitting an inboard engine or 'stern-drive' layout. A further useful feature is the provision of a flexible neck to the jet pump intake that facilitates steerage and trim. The stator-gearbox housing may be manufactured as a single component or comprise three separate components that are bolted together. An important feature of the stator-gearbox drive housing is that water is able to pass through the stator section of the stator-gearbox and a vertically arranged drive shaft without significant frictional losses due to turbulence. This is achieved by passing the shaft through a thickened stator blade that is hydrodynamically matched to the adjacent blades.
