The Suzuki DF250AP 4-Stroke Outboard Engine delivers 250 HP of advanced V6 performance for larger recreational, fishing and commercial boats. Combining Suzuki's sophisticated four-stroke engineering with electronic fuel injection, Drive-by-Wire controls and Suzuki Selective Rotation technology, the DF250AP is designed to provide strong acceleration, smooth operation and efficient cruising performance.
Powered by a 4,028 cm³ V6 engine with a 55-degree cylinder-bank angle, the DF250AP produces 183.9 kW (250 HP) and operates across a 5,500–6,100 rpm full-throttle range. Suzuki's DOHC 24-valve configuration and multi-point sequential electronic fuel injection provide the foundation for responsive and efficient performance.
One of the DF250AP's standout technologies is Suzuki Selective Rotation, which allows the outboard to operate in either standard or counter-rotation configurations using the appropriate setup. This provides greater flexibility for single- and multi-engine installations and can help boat builders and owners optimise propulsion layouts.
The DF250AP uses Suzuki's electronic Drive-by-Wire control system to manage throttle and gear shifting. The system is designed to provide smooth, precise control with positive gear engagement and responsive throttle operation, particularly useful when manoeuvring larger boats at low speeds.
Suzuki's Lean Burn Control System automatically adjusts the fuel mixture according to operating conditions, helping optimise fuel consumption across a wide range of engine speeds. An oxygen sensor provides feedback to further regulate the air-to-fuel ratio, supporting efficient combustion and stable operation.

Specifications are based on Suzuki's published DF250AP data; exact equipment and specifications can vary by market and model configuration.
The DF250AP incorporates a range of technologies developed for Suzuki's high-performance V6 outboard platform. Its DOHC 24-valve engine, electronic fuel injection, two-stage gear reduction and offset-drive architecture are designed to deliver a strong combination of power, efficiency and smooth operation.
The engine's two-way water inlet system increases water flow to the cooling system, supporting efficient temperature management and improved performance in demanding operating conditions.
The DF250AP is available for X (25-inch) and XX (30-inch) transom heights. Current Suzuki specifications list approximately 290 kg for the X configuration and 299 kg for the XX configuration, excluding propeller and engine oil.
Because shaft length and weight can vary by configuration and market, the correct version should be selected according to the boat's transom height and installation requirements.
The Suzuki DF250AP is well suited to:
The Suzuki DF250AP combines substantial V6 power with sophisticated electronic control and fuel-management technologies. Its 250 HP output, Selective Rotation capability, Drive-by-Wire controls, Lean Burn technology and power trim and tilt make it a versatile high-performance outboard for demanding marine applications.
For boat owners looking for strong acceleration, precise electronic control, efficient cruising and Suzuki's advanced V6 four-stroke technology, the DF250AP is a powerful and highly capable propulsion solution.
