Superior Engineering That Sets It Apart

When you invest in a Suzuki outboard motor, you’re choosing a product that stands the test of time. The DF40A is no exception—it boasts several engineering highlights that make it one of the most desirable options in its horsepower category.

Maintenance-Free Timing Chain

Suzuki’s oil-bathed timing chain is a standout feature. Unlike conventional belts that need periodic replacement, this timing chain is maintenance-free and self-adjusting, ensuring durability and hassle-free operation. This is especially advantageous for long trips or commercial use where reliability is critical.

Lean Burn Control System

With fuel prices constantly fluctuating, the DF40A’s Lean Burn Control System saves money over time. This system intelligently predicts fuel needs according to operating conditions, resulting in optimal air-fuel mixture ratios. The outcome? Up to 14% better fuel efficiency than comparable models.

Award-Winning Innovation

Incorporating the Suzuki Troll Mode System, the DF40A allows you to fine-tune your trolling speed in precise 50 RPM increments. This innovation is especially useful for anglers targeting species that require subtle bait movement. The feature was so groundbreaking it earned recognition at the 2011 Miami Boat Show with the prestigious NMMA Innovation Award.
