Suzuki DF200AP Black

Semi-Direct Air Intake System

A specially designed cowl and semi-direct air intake system were designed to provide cooler air to the tuned long-track intake manifold while a four valve per cylinder DOHC powerhead with Variable Valve Timing lets the engine breathe more efficiently increasing acceleration and top end speed. Added to that are a fuel injection system and Suzuki’s Lean Burn Technology for improved fuel economy.

Big Block High Performance Engine

With the DF200A, our goal was to build an outboard that provides all of the power and performance of a 147kW (200PS) class V6 outboard using a lighter, more compact four-cylinder configuration. To deliver that level of performance our engineers used an inline four-cylinder engine with a 2.9-liter “Big-Block” displacement and a higher 10.2:1 compression ratio to generate impressive acceleration and low-end torque.

Suzuki Lean Burn Control System

The Suzuki Lean Burn Control System is an intelligent fuel delivery system that achieves remarkable improvements in fuel consumption making fuel-efficient four-stroke outboards even more economical. Monitoring engine performance and operating conditions in real time, the system uses the 32-bit onboard ECM to predict fuel needs and deliver a leaner, more precise fuel mixture across the outboard’s operating range. The results show significant improvements in fuel economy across the entire powerband, including the cruising range where the engine is used a majority of the time. Comparing the new DF200A with the original V6 DF200, tests show up to a 19% increase in fuel efficiency mainly in the cruising range (around 70% of its maximum speed).

Suzuki Multi Stage Induction (MSI)

Getting the right amount of air into the cylinder has a great impact on performance. High-speed operation typically requires a greater volume of air, low-speed less. Suzuki’s Multi-Stage Induction system meets these needs by utilizing two intake manifold pipes per cylinder to ensure the engine gets the right amount of air. At low rpm, air enters the combustion chamber through a longer, curved manifold pipe designed to improve combustion and improve low-end torque. As rpm increases, the valves open on the direct intake pipes. Shorter and lacking resistance, these pipes allow a greater volume of air into the chamber, increasing the engine’s ability to breathe efficiently at high rpm resulting in higher power output during high-speed operation.

Quiet Operation

Suzuki four-stroke outboards have long been noted for their exceptionally quiet operation. Suzuki engineers go to great lengths incorporating methods designed to keep outboard operation as quiet as possible. In a noise comparison test between the DF200A and a competing 147kW (200PS) in-line four-stroke outboard, the results clearly show that the DF200A runs quieter than its competitor.

Suzuki Selective Rotation

Large boats equipped with multi-outboard installations generally pair a standard rotation outboard with a counterrotation model to keep the boat traveling in a straight line and on an even keel. Once requiring the purchase of a dedicated counter-rotation model, Suzuki’s innovative Suzuki Selective Rotation eliminates that need by incorporating a special, unified design of gears, shaft, and bearings in the lower unit that allow the outboard to operate reliably and efficiently in either direction.

Available only on the DF200AP, counter-rotation operation requires an optional activation switch that connects to a circuit inside of the engine compartment plus the installation of a counter-rotation propeller*3.

*3: Consult with your dealer before changing Standard Rotation to Counter-Rotation (or vice versa).

The optional switch and additional propeller are needed to change the outboard’s rotation.

Resonator

The engine’s exhaust system is a well-known source of engine noise, but another, often overlooked source is the intake manifold. Air being sucked into the intake manifold at high velocities can generate a harsh sound. The DF200A incorporates an air intake resonator that reduces such noise keeping operation exceptionally quiet.

Suzuki Precision Control (Electronic Throttle and Shift System)

Only available with the DF200AP version, Suzuki Precision Control is a computer-based throttle and shift system that replaces mechanical control cables with a digital fly-by-wire system to eliminate friction and resistance in the controls. The system provides smooth and precise control along with crisp, immediate shifting which are particularly helpful during low rpm operation and when maneuvering.

Combined with Suzuki’s Lean Burn Control System, the system also helps to improve fuel efficiency over a wide operating range.

Suzuki Precision Control also features safeguards that help protect the engine and drive against damage due to mishandling and is compatible with single, twin, or triple installations as well as dual station operation.

Dual Engine Flush Ports

Over time, salt, sand, and dirt buildup can restrict flow in the cooling system causing damage. To help prevent such buildup, both outboards are equipped with two freshwater flush ports that make flushing the cooling system as easy as possible. With one port located on the port side of the down housing and a second on the front panel, you’ll always have easy access to the flushing system whether the boat is in or out of the water.
