SUZUKI V6 4-STROKE OUTBOARDS TECHNICAL HIGHLIGHTS:
In what has become a SUZUKI MARINE tradition, the new 200 HP, 225 HP and 250 HP V6 4-strokes for 2004 are introducing new technological advancements to the outboard power industry. Also in the SUZUKI tradition, each of the advanced features on these motors delivers a specific and important benefit to the boating enthusiast. Technical highlights of these groundbreaking motors include:

Narrow V-Angle — No other manufacturer uses a 55-degree V block. This creates a narrow-profile motor that is smaller in physical size than comparable 4-strokes — very important when rigging today's boats. SUZUKI's proven offset driveshaft design further reduces the motors' overall size and balances the weight better on the transom — for improved boat performance and reduced motor vibration.

Variable Valve Timing — This exclusive SUZUKI feature is utilized on the DF250 to provide the low-end to mid-range torque needed for larger boats and heavy loads. An aggressive camshaft profile is capable of delivering 250 HP. Adjusting intake valve timing boosts engine output on the DF250 to deliver the strongest possible acceleration to move larger boats.

Under normal operating conditions, there is a momentary overlap when both intake and exhaust valves are open. A hydraulic phase adjuster on the camshaft controls precise increases or decreases of this overlap by advancing or retarding intake timing in relation to the crankshaft. Opening the intake valve earlier in the low- and mid-range allows for more efficient intake, a stronger power stroke, reduced emissions and improved fuel economy.

Multi-Stage Induction — This SUZUKI exclusive is used on the DF250 and DF225 to provide the performance boater's demand from these size motors, on all styles and sizes of boats. These outboards feature two intake pipes per cylinder, one for low engine speeds and one for high engine speeds. At low rpm, air enters the combustion chamber through the longer, curved pipe. The curve allows the most suitable volume of air into the chamber to improve combustion and boost low-end torque. When rpm passes a pre-set threshold, a valve is activated that allows air to enter the chamber directly through a short, straight pipe for better high-speed power output.

Multi-Point Electronic Fuel Injection — SUZUKI’s advanced digital sequential fuel injection is controlled by an Electronic Control Module, a powerful computer that monitors critical engine data in real time and instantly calculates the optimum amount of fuel to be injected under high pressure into each cylinder. High-performance plate-type injectors provide superior fuel atomization and cleaner combustion.

32-Bit Onboard Computer —With twice the power of computers on comparable outboards, SUZUKI's 32-bit onboard computer is capable of managing these motors´ advanced systems to provide optimum performance and efficiency under all operating conditions. In addition, advanced new builtin diagnostics will allow servicing technicians to rapidly download operating history data and pinpoint any problems that might occur.
Direct Ignition System — SUZUKI’S proven Direct Ignition System uses an ignition coil built into the spark plug cap. This reduces the number of parts, simplifies the wiring system and greatly reduces electronic engine "noise" that can interfere with marine electronics.

High-Output Integrated Alternator — Because it is integrated under the flywheel, SUZUKI’s 54-Amp alternator doesn't require a separate, power-robbing belt drive. This unique configuration also provides cooling airflow from the flywheel cooling fins. Designed to crank out 32 Amps of power at only 1,000 rpm, this alternator makes sure you can keep all your electronics, lights and pumps running, even at trolling speeds.

Exclusive Starting System — SUZUKI 4-strokes are so quiet, sometimes you can't hear them running. The V6 4-strokes feature a new starting system that prevents the starter from engaging if the motor is already running. The operator must turn the key to the "off" position before starting. In addition, the starter will not operate if the safety stop switch lanyard is not connected, thus preventing the engine from turning over.

Multi-Function Tachometer — Using data provided from engine sensors, this system alerts the operator to any problems that may require attention. To ensure proper maintenance, an oil change reminder tells the boater when it is time to change engine oil under normal conditions.
