Features:

Make Speed a Priority – The DF4A offers acceleration and speeds far beyond the average capability of most small watercrafts, and can be attached or removed with ease. Bring a little power to your weekend plans, and upgrade your ride.
Don’t Be Held Down – The DF4A is fully equipped for whatever challenges lie ahead, fully portable and fits nearly any water vessel. Swap out how you use your DF4A, whether it’s for a weekend on the duck boat or the paddle board. If you don’t want to be tied down, this is the engine for you.
Easy To Start After Storage – Because 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.
Offset Crankshaft – Positioning the crankshaft slightly off center 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.
Quiet Operation – The low noise level is the result of a silencer, designed to optimize the capacity and shape of the air intake. The new design of the rocker arm and the plane 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 plane type.
Highly Reliable Lubricating System – The forced lubrication system of the DF4A has an additional oil passage to the upper and lower crankshaft and connecting rod big end. The addition of a first-in-its-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.
Three-Way Storage – The new fuel and lubricating systems allow more convenient storage of the outboard on any of three sides (port, starboard or front) without worrying about the storage orientation.
New Tilt System – The tilt system of the 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.
Outstanding Handle Operation – An ease of handling that has enjoyed great popularity. Further improvements to the tiller handle have successfully mitigated vibrations contributing to fatigue and stress when transmitted to the hand during operation. The DF4A excel at vibration mitigation, particularly in the mid-range.
Improved Portability – The 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.
