IN‐LINE 4 200-150HP

DF175A / DF150A

DF175A

High-end performance and features put the new DF175AP/150AP in a rank above the rest.

Fuel Efficient

With a combination of our Lean Burn technology, a semi-direct intake system and a high performance compression ratio of 10.2-to-1, these new outboards deliver clean, efficient power. Compared to the current 175 and 150, the DF175A is 14% more fuel efficient and the DF150A shows a 7% improvement for significant savings at the fuel dock.

Fuel Efficient

Powerful

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.

Powerful

Quick Acceleration

The DF150A and DF175A now share the same engine block used for our popular DF200A. More displacement and improved 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.

Quick Acceleration

Reliable

These new outboards take full advantage of Suzuki’s proven Ultimate 4-stroke technology to provide season after season of reliable performance. A knock sensor keeps the engine running smoothly for improved durability. An O2 sensor improves engine efficiency and Suzuki’s water detecting system helps protect the engine from the effects of bad gas, which include poor combustion, lower power output and corrosion.

Advanced Technology for the Performance

Offset Driveshaft

EXPLANATION

The engine powerhead is offset closer to the transom, moving the outboard’s center of gravity forward.

ADVANTAGE

  • Less vibration
  • More compact engine
  • Stable steering performance

2-Stage Gear Reduction

EXPLANATION

This system which incorporates the Offset Driveshaft features a first stage reduction between the crankshaft and drive shaft and a second stage reduction inside the gear case. This design makes a larger gear ratio possible, allowing it to turn a large diameter propeller for high propulsive efficiency while providing greater torque.

ADVANTAGE

  • High propulsive efficiency with large diameter propeller.
  • Powerful navigation, maintaining propeller rotation even with a larger load.
  • Power to turn large diameter propellers, offering quick acceleration.

Multi-Stage Induction System

EXPLANATION

This system brings cooler air directly into the multi- stage intake manifold, making it possible for the engine to operate more efficiently.

ADVANTAGE

  • Greater acceleration and top-end speed.

Multi-Stage Induction System

Semi-Direct Air Intake System

O2 Sensor Feedback Control System

EXPLANATION

This system provides accurate, real-time information Delete the ECU uses to manage the fuel/ air ratio as operating conditions change.

ADVANTAGE

  • Enables emissions to be clean and stable.
  • Helps maintain optimum engine operating efficiency across the engine’s full operating range.

Lean Burn

EXPLANATION

The Lean Burn Control System supplies the right fuel and air mixture depending on the navigation conditions.

ADVANTAGE

  • Significant improvement in fuel economy in all speed ranges especially at cruising speed.
  • Fuel use and expense are reduced thanks to improved fuel economy.

Suzuki Anti-Corrosion System

EXPLANATION

Special protection is applied to the aluminum surface using high strength bonding to protect the aluminum made exterior parts.

ADVANTAGE

  • Protection against corrosion helps increase the overall engine durability.

Suzuki Anti-Corrosion System

Suzuki Water Detecting System

EXPLANATION

Designed to help protect the engine from moisture in the fuel utilizing a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel.

ADVANTAGE

  • Protects engine from poor combustion, lower power output, and corrosion.
