PRODUCT INFORMATION

LIGHTWEIGHT DESIGN – HEAVYWEIGHT POWER When it comes to selecting an outboard for your boat, the balance of power and weight becomes an important issue in making the right choice. Suzuki engineers have solved that problem with a series of 150, 175 and 200 horsepower inline-4 cylinder outboards that deliver the power you want, without weighing you down. With the DF200A, and now with our DF150A and DF175A, our goal was to build an outboard that provides all of the power and performance you want using a lighter, more compact four-cylinder configuration. To deliver that level of performance our...

Advanced Technology for Performance Suzuki Lean Burn Control System Comparison of Fuel Eﬃciency per Liter (New DF200A vs. V6 DF200) The Suzuki Lean Burn Control System is an intelligent fuel delivery system that achieves remarkable improvements in fuel consumption. 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...

Big Block—High Performance Engine The design goal for these models was to provide boaters with exciting performance from a more compact, lighter weight fourcylinder engine. For this, Suzuki engineers started with their 2.9-liter straight-four “Big Block” design with a DOHC four-valve per cylinder powerhead and a 10.2:1 compression ratio. Getting the right amount of air into the cylinder has a great impact on performance. High-speed operation requires a greater volume of air, while low-speed operation needs less air. Suzuki’s MSI system meets these needs by utilizing two intake manifold...

Offset Drive Shaft Pioneered by Suzuki, the use of the offset drive shaft on fourstroke outboards has long been utilized to reduce the size of the outboard. Found on all Suzuki four-strokes from the DF70A and up, this design positions the crankshaft in front of the drive shaft simultaneously moving the outboard’s center of gravity forward. While the design contributes greatly to the outboard’s overall compactness and increased power performance, it also moves the engine’s axis of inertia, the point where engine vibrations are at a minimum, up over the upper engine mount, thus greatly...

Designed with Convenience in Mind Tilt Limit System Water-Cooled Voltage Regulator with Isolator To protect the boat and motor from damage that can occur when tilting the motor, these outboards incorporate a user adjustable tilt limit switch. When adjusted properly, this system prevents the outboard from tilting beyond a predetermined point. Knock Sensor Water-cooled voltage regulators incorporated on these outboards dissipate heat in the regulator to enhance durability. The battery charging system also incorporates an isolator function that allows the use of two batteries. The system...
