A water jet propelled water craft has a jet pump impeller (24) mounted in a jet tube (18) and driven by a water cooled engine (16). A heat exchanger (30′) for the engine coolant is incorporated into a housing for the jet pump impeller (24) and takes the form of a chamber surrounding a through bore of the jet tube (18). The chamber has an inlet and an outlet for the flow of coolant and contains a series of staggered baffles that define an oscillatory and circumferential flow path for the coolant between the inlet and outlet.
