\n \nThe overhead integral fuel tank and the new lubricating systems allow transport and storage of the outboard on any of three sides (port, starboard, or front) without leakage of fuel or oil. \n \nBecause the overhead fuel tank is placed right above the carburettor, it also allows gravity fuel supply, enabling the engine to start instantly right after filling fuel, even after long-term storage. These features have enhanced its user-friendliness as a portable outboard motor. \n \n

EASY AFTER-STORAGE START

\nBecause the integral overhead fuel tank and one-way valve allow gravity fuel supply, the engine can be started without opening the engine cover, even after long-term storage. \n \n

\n

HIGHLY RELIABLE LUBRICATING SYSTEM

\nThe forced lubrication system of the DF6A, DF5A and DF4A has an additional oil passage to the upper and lower crankshaft and connecting rod big end. The addition of a first-in-class oil filter greatly increases the reliability of the lubricating system. Furthermore, the new position of the oil window allows for visual confirmation of the actual lubricating condition. \n \n

\n

OFFSET CRANKSHAFT

\nPositioning the crankshaft slightly off centre of the cylinder reduces lateral pressure against the cylinder wall as the piston moves up and down in the cylinder. The result is smoother piston movement, which improves operating efficiency. \n \n

\n

QUIET OPERATION

\nThe low noise level is the result of a silencer, designed to optimise the capacity and shape of the air intake. The new design of the rocker arm and the plain bearing of the crankshaft also help reduce the noise level. We also changed the structure of the parts related to the rocker arm and eliminated its excessive play. In addition, we changed the crankshaft bearing from a common ball type to a plain type. \n \n

\n

THREE-WAY STORAGE

\nThe new fuel and lubricating systems allow extremely convenient storage of the outboard on any of three sides (port, starboard or front) without worrying about the storage orientation. \n \n

\n

IMPROVED PORTABILITY

\nThe carrying handle integrated into the lower cover has been rounded and made easier to hold. An additional grip at the front of the lower engine cover provides the convenience of carrying the outboard with both hands. \n \n

\n

NEW TILT SYSTEM

\nThe tilt system of the DF6A DF5A and DF4A offers different up-and-down paths of the shallow drive arm compared with the previous models. When raised, it can be locked at three positions. When lowered, it can just be smoothly moved to its lowest position without locking. \n \n

\n

OUTSTANDING HANDLE OPERATION

\nAn ease of handling that has enjoyed great popularity. \nFurther improvements to the tiller handle have successfully mitigated vibrations contributing to fatigue and stress when transmitted to the hand during operation. The DF6A, DF5A and DF4A particularly excel at vibration mitigation in the mid-range. \n \n

SUZUKI’S ANTI CORROSION SYSTEM

\nSuzuki protects its outboards with an anti-corrosion finish specially developed by Suzuki. Applied directly to the aluminium surface it maximises the bond between the finish and the surface, increasing the protection and durability of parts that are constantly exposed to saltwater. \n \n
