Suzuki’s Award Winning Technology The product of unrivaled expertise and world class technology, Suzuki’s four-stroke outboards have long been on the cutting edge of outboard performance winning acclaim and awards for 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 oil bathed, self-adjusting...

Torque Curve Compact High Performance Engine The DF225 and DF250 all utilize a 3.6-liter DOHC, 24-valve V6 engine that produces 225hp / 250hp in their respective configurations. At 3614cm3 these engines feature big displacement, but innovative design makes them light and the most compact outboards in their class. Key features shared by these powerful four-strokes include Suzuki’s digital sequential electronic fuel injection controlled by a 32-bit onboard computer and Suzuki’s offset driveshaft, which allows for the use of a larger prop. In addition to that, the DF225/250 utilizes...

Two-Stage Gear Reduction With such a high performance engine now at our disposal, losing any power in the propulsion system would be a waste, so our engineers chose an efficient means of supplying maximum propulsion. A propeller rotating at high speed in the water has a tendency to slip and when two propellers of the same pitch but different diameters are rotated, the smaller propeller will slip more than the larger. So to obtain maximum propulsion, spinning a larger diameter propeller with a suitable pitch is the answer. But to spin a larger propeller, more torque in the propeller shaft...

Two-Stage Cam Drive System The two-stage cam drive system utilized in the DF225/250 incorporates both gears and a chain. The system’s first stage gears transfer power between the crankshaft and the drive shaft (32:40) while the second stage utilizes a chain to deliver power from the drive shaft to the camshaft (20:32). This allows for the use of smaller diameter cam sprockets, which in turn allows for a reduction in valve angles also reducing the size of the cylinder head.The timing chain is equipped with an automatic hydraulic tensioner to keep the chain properly tensioned. This system...

LOW EMISSIONS Multi Point Electronic Fuel Injection As Suzuki was the first in the industry to incorporate multi point electronic fuel injection in a four-stroke outboard with the DF60 and DF70, it is only natural that the DF225/250 would incorporate the same. Along with Suzuki’s Multi Point Sequential Fuel Injection, the DF225/250 incorporate an ECM (Engine Control Module) which constantly monitors crucial data, in real time, from a series of sensors placed in critical areas on the engine. This comprehensive network of sensors includes the Manifold Absolute Pressure Sensor, Crankshaft...

CONVENIENT FUNCTION High Output Alternator The DF225/250 are equipped with a high output alternator that delivers 54 A(12V) of electrical power. Designed to produce a majority of this power at low rpm, around 38 A is delivered even at 1,000rpm. It delivers a generous amount of current to keep an assortment of electronics up and running. Tilt Limit Switch The motor tilt system incorporates a user programmable tilt limit switch, which prevents the motor from tilting beyond a predetermined position. This can be used to protect both the boat and motor from damage that can occur when tilting the...

Suzuki Motor Corporation Suzuki history begins with the founding of Suzuki Loom Works by Michio Suzuki in October 1909. Realizing that weaver wanted to produce cloth both vertical and horizontal patterns, he developed an automated loom capable of weaving patterned cloth from space dyed yarn. His commitment to innovative engineering was the start of an uncompromising focus on creating products that meet people’s needs and offer new life style possibilities. While the company has evolved, diversified, and expanded since then, we have always honored our founder’s commitment to innovative...
