The DF4, DF5 and DF6 make the advantages of advanced clean burning, fuel saving four stroke technology available to the portable engine user. Ease of operation and handling ranked very highly in the design criteria.

Power is provided by a single cylinder OHV engine with a displacement of 138cc - the largest in the class. Combined with the lightweight this produces excellent low to mid range torque and fast acceleration. An industry first is the digital capacitor discharge ignition system. This combines the ignition coil and control processor into a corrosion resistant single unit which produces precise control of the ignition timing, gives stable idling and has a built in rev limiter. The tiller handle is mounted on the steering bracket allowing the operator to sit well forward improving weight distribution. Other features include 180 degree steering providing good manoeuvrability even in shallow water drive; a 1.5 litre integral fuel tank and a large carrying handle
