More Power

With more torque (3.1% more for the DF150A and 2.7% more for the DF175A), as well as Suzuki’s proven offset driveshaft layout with 2-stage gear reduction, these new outboards generate more power throughout the full rpm range. Even on heavier, fully loaded boats, the DF150A and 175A take performance to the next level.

Quick Acceleration

The DF150A and DF175A now share the same engine block used for our popular DF200A. Big displacement and precise mechanical design combine for quicker acceleration, whether out of the hole or in mid-range. We’re satisfying our customers’ desire for performance and improved fuel economy.

3 + 3 years Recreational Warranty

All recreational/privately registered Suzuki Outboards come standard with 3-years / unlimited hours manufacturer’s warranty. Recreational outboards are also eligible for a bonus 3-year Warranty providing that an authorised Suzuki Marine Dealership completes servicing as per the owners manual schedule. The Suzuki dealer must use only genuine parts and oils during both manufacturer’s and bonus warranty periods.
