Suzuki 250 HP Outboard Engine

Suzuki 250 HP Outboard Engine

Suzuki 250 HP Outboard Engines have F - N - R gears, water cooling, multi-function gauge, choice of control box, Drive-by-wire electronic controls, Suzuki selective rotation, choice of stainless steel propeller and power trim and tilt.

Suzuki 250 HP Outboard Engine Key Features

• Largest reduction gear ratio in its class, a large reduction gear ratio leads to powerful torque for quick acceleration and great top-end speed.
  Water grip Propeller.
• Stainless steel propeller with a new interchangeable square shaped bush that offers efficient conversion of engine power to propulsion resulting in better grip and performance for our powerful outboards.
• Suzuki Selective Rotation Selective rotation offers a more robust gearing in the lower unit enabling the prop to rotate in both directions.
• Variable Valve Timing (VVT). The system is controlled by hydraulic pressure from the oil pump and the process happens automatically so all you have to do is enjoy the power and performance.
• Suzuki Lean Burn Control System. Suzuki's Lean Burn Fuel Control Technology predicts fuel needs according to operating conditions, then delivers the optimum fuel/air mixture to the engine resulting in greater fuel economy.
• Suzuki Precision Control This technologically advanced system gives smooth, precise control with crisp, immediate shifting particularly at low revs when manoeuvring and helps improve fuel efficiency.

DF250 APXX - Extra Extra Long shaft (762mm), Electric start, and power tilt. Colour: Pearl Nebular Black. Weight - 299 kg.

Suzuki 250 HP FAQs

What is the difference between the DF250 and the DF250AP?

While both are powerful 3.6-litre V6 engines, the DF250AP is the "Ultimate Outboard" version. It features Suzuki Precision Control (electronic drive-by-wire) and Suzuki Selective Rotation, allowing the engine to be configured for either regular or counter-rotation—ideal for twin-engine setups.

What size boat is the 250hp outboard best suited for?

This engine is a popular choice for large RIBs (7.5m+), offshore fishing boats, and heavy-duty commercial vessels. Its high torque-to-weight ratio makes it excellent for boats that require a fast "hole shot" to get on the plane quickly. Performance & Innovation

Does the 250hp include Suzuki Lean Burn technology?

Yes. The 250hp range utilizes the Lean Burn Control System, which monitors engine sensors to deliver a precise, lean air-to-fuel ratio. This can result in up to a 14% improvement in fuel economy at cruising speeds compared to non-lean burn models.

What is the "VVT" mentioned in the 250hp specs?

VVT (Variable Valve Timing) is used to optimize the intake valve timing. In the 250hp, this provides significantly more low-to-mid-range torque, giving you powerful acceleration and "punch" when you push the throttle, regardless of the load.

How does the "Multi-Stage Induction" system work?

Think of it like a variable intake manifold. At low speeds, it uses longer intake pipes to increase airflow for better torque; at high speeds, it switches to shorter pipes to allow more air into the cylinders for maximum top-end horsepower, ease of use & Reliability

Is the 250hp compatible with electronic steering?

Yes. The DF250AP is fully compatible with Suzuki Precision Control. This replaces traditional mechanical cables with electronic wiring, providing smooth, instantaneous shifting and throttle response.

How does the Keyless Start System work?

The 250hp AP model features a water-resistant proximity key fob. As long as the fob is near the console, you can start the engine with the touch of a button. It also acts as an immobilizer to deter theft.

What is the benefit of the Offset Driveshaft on this V6?

By placing the driveshaft in front of the crankshaft, Suzuki moves the engine's centre of gravity forward. For a 250hp engine, this means less vibration on your transom and a more compact design that fits better on modern boat hulls.

What fuel should I use for the Suzuki 250hp? 

Suzuki recommends high-quality unleaded petrol (91 RON or higher). It is also highly recommended to use Ecstar V7000 Synthetic Blend marine oil to protect the V6 internal components from the harsh salt-air environment. 

How do I know when the engine needs a service? 

The Suzuki Multi-Function Gauge (included with the 250hp) will display service alerts and engine hours. It also features a "troll mode" and diagnostic readouts to keep you informed of the engine's health in real-time.
