Suzuki Marine’s latest DF115 and DF140 four-stroke outboard engines are available in both mechanical and drive-by-wire variants to suit a wide range of boats, individual requirements, and budgets.
Superseding the popular DF115A and DF140A, the mechanically-driven DF115B and DF140B feature a host of innovative updates, many of which are shared with the DF115BG and DF140BG Suzuki Precision Control (SPC) drive-by-wire models.
The compression ratio has been increased from 9.7:1 to 10.6:1 to achieve greater top speed and acceleration produced by the 2.0-litre displacement inline four-cylinder engines. Lean Burn fuel efficiency has also been significantly improved compared to the outgoing “A” series models. Tests have demonstrated as much as 10% improvement across mid-range to high-end cruising speeds.
The redesigned cowl of the DF115B/BG and DF140B/BG features a sporty, streamlined profile, sculptured to complement any type of boat with its smooth exterior appearance. It also incorporates a new air intake structure for improved water separation and a silencer-resonator system to attenuate engine sounds and provide a pleasant boating experience at all engine speeds/RPM.
For ease of maintenance, Suzuki has now made it possible to replace the oil filter by simply removing the upper engine cover. A new oil spill catcher surrounding the oil filter mount allows for filter changing without making a mess. A water detection fuel filter has also been added to help protect the engine against contaminated fuel.
An optimised gear oil passage contributes to lower gear oil temperatures with greater cooling efficiencies increasing the durability of the pinion gear. A large capacity fuel pump, optimised O2 sensor mounting location and use of zinc-coated rustproof fasteners further contribute to Suzuki’s renowned durability.
As the world’s Ultimate Outboard Motor brand, Suzuki always remains focused on providing the ultimate marine experience, which requires a healthy and clean marine environment. The DF115B/BG and DF140B/BG is now equipped with a Micro-Plastic Collecting Device, which works by collecting micro-plastic whilst the engine is moving, without any effect on the performance when boating.
Featuring striking new graphics, the DF115B/BG and DF140B/BG are available in the Suzuki Pearl Nebular Black colour scheme, while the BG variant is also offered in a Super Cool White. Both the B and BG series are available in 20-inch and 25-inch shaft lengths and are backed by Suzuki’s 3+3 year recreational warranty.
