Suzuki DF4A

Dealer Price $1,899 CAD

The DF4 brings 4-stroke performance and efficiency to portable outboards. Compact and lightweight, the DF4 is easy to transport and delivers surprising low- and mid-range torque for quick acceleration.

Knowing that small portables like the DF4 get transported a lot, we set out to design this outboard compact and lightweight to make transporting easier. Not to stop there, we added features that would make its operation easy and more user friendly. As four-strokes, the DF4 outboard deliver clean, economical operation, and being made by Suzuki, you know it delivers excellent power, performance, and durability.

Powering the DF4, is a single-cylinder 4-stroke OHV engine with a large displacement of 138cm3. Its excellent mid-range torque combined with light weight results in excellent acceleration. Also, four-stroke operation provides the DF4 with greater fuel-efficient operation, less vibration and quiet operation while eliminating the need for mixing oil with the fuel, etc. This keeps your boating experience clean, pleasant and user friendly.

Carrying the outboard is made easier with the incorporation of a large, ring shaped carrying handle. Designed with smooth edges and lacking any sharp angles, the large carrying handle offers plenty of space for both hands. A tilt up handle built into the backside of the engine cover offers easy tilting of the outboard. Pulling back on the handle makes tilting of the engine from the normal drive position to any one of the two shallow water drive positions or tilt up position a simple operation.

The pilot water hole is located upstream of the cylinder to confirm that there is water circulation soon after the motor is started. The pilot water hole’s water inspection tube is removable to permit cleaning of the tube and the attachment of an optional connector that allows freshwater flushing of the water jacket.

Equipped with a built-in 1.5-liter fuel tank for convenience and user friendly performance when portaging or rigging the DF4 to a variety of boats.
