A jet propelled boat having a tunnel at its rear end in which a jet propulsion unit is movably supported. The support for the jet propulsion unit is readily detachable so that the jet propulsion unit may be easily removed from the tunnel. The tunnel is closed at its rear end by a transom of the boat in which a small opening is formed through which the jet propulsion unit may be removed.
