Suzuki DF70 Four-Stroke Outboard

Suzuki DF70 Four-Stroke Outboard

Suzuki went to great lengths to maximize the efficiency of its DF70, DF80 and DF90 4-stroke outboards—including cutting overall length by 3 inches. A new lightweight cowling and streamlined lower unit further reduce overall weight to 341 pounds. The shorter length, along with a user-adjustable tilt limit switch, provides for a better fit on boats with limited transom clearance, such as flats boats with poling platforms. The heart of the engines is a new 91.7-cubic-inch inline four-cylinder, dual–overhead cam powerhead. An offset driveshalft and two-stage gear reduction allowed engineers to move the engine's center of gravity forward--over the transom--and reduced overall dimensions. A 27-amp alternator cranks out plenty of juice, even at low rpm, to power electronics, trolling motor and livewell pumps. An oil-bathed, self-adjusting timing chain minimizes scheduled maintenance.
