Suzuki’s Award Winning Technology
At its first showing at a special preview at the 2003 Miami International Boat Show, the DF250 captured the NMMA (National Marine Manufacturers Association) 2003 Innovation Award making this the fourth Innovation Award for Suzuki.
The product of unrivaled expertise and world class technology, Suzuki’s four-stroke outboards have long been on the cutting edge of outboard their advanced technology, innovative ideas, and designs. We were the first to introduce a digital Electronic Fuel Injection four-stroke; an idea that allowed the DF60 and DF70 to receive further recognition from the International Marine Trades Exposition and Convention when they captured the IMTEC Innovation Award. We were the first to offer an automotive type self-adjusting timing chain in a four-stroke engine with performance enhancing dual overhead cams and four valves per cylinder. This brought us recognition again, when our DF40 and DF50 received the IMTEC Innovation Award making Suzuki the first manufacturer to receive this distinguished award two years in a row, and also giving us our third IMTEC award, again an industry first.
Relying on experience we’ve gained through the manufacture of not only outboards, but technologically- advanced motorcycles and automobiles, our engineers have put decades of knowledge into the design, development, and production of an all new V6 motor designed specifically for outboard use. This new V6 holds some of our most advanced innovative ideas to date, making it a showcase for Suzuki’s advanced four-stroke outboard technology.
DOHC 24-Valve with VVT Delivers High Performance
Our engineers designed a 3.6-liter V6 engine——and an aggressive cam profile designed specifically for the. However, our goal was not just to create an outboard that could deliver 250PS (184kW), but to create an outboard that could deliver high performance that suits its 250PS (184kW) output along with the many benefits that a four-stroke can deliver.
A high performance camshaft designed to deliver 250PS (184kW) produced the wanted power output, but to get the strong mid and low-end torque outboards need when accelerating requires altering valve timing. In general, only using a camshaft setting like those found in racing engines produces an engine that develops insufficient low and mid range torque. This is because the valve timing for intake and exhaust differs according to load and engine speed.

Self-adjusting timing chain
Simple, effective and maintenance free timing chain that runs in an oil-bath so it never needs lubricating and equipped with a hydraulic tensioner so it remains properly adjusted at all times.
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.
Multi-stage induction enhances the engines performance by allowing the right amount of air into the cylinder resulting in higher power output during high speed operation.
Largest reduction gear ratio in its class
A large reduction gear ratio leads to powerful torque for quick acceleration and great top-end speed.
Offset drive shaft
The offset drive allows us to make our outboard engines smaller by moving the outboards centre of gravity forward, improving weight distribution, power output, balance and reduces vibration.
SELF-ADJUSTING TIMING CHAIN
The timing chain runs in an oil-bath so it never needs lubricating, and is equipped with an automatic hydraulic tensioner so it remains properly adjusted at all times.
- More durability compared to belt types of same class.
