The Stuart 6A is the largest engine in our range, being capable of producing Approx. 4 bhp at 120 psi whilst running at 750 rpm. This is enough power to drive an eighteen to twenty two foot boat. This engine is fitted with a boiler feed pump as standard to keep the water supply constant. A condenser is also fitted together with an Edwards style pump to keep it clear of condensate. The Stuart 6A is only supplied as a full set of castings & drawings, we do not supply any fixings or materials.
