Axial flow passes the water straight through the impeller for maximum volume.
They out pull comparable workboat propellers with operating efficiencies in the eight to 15 knot range. Nomera jets are mixed flow jets. Mixed flow jets are characterized by a highly accelerated mass flow giving velocities for speeds of 20 to 60 knots, depending on model and horsepower. The propulsion efficiency will match a propeller in the 30 to 40 knot area.
