Suzuki Marine ‘s 350- and 300-horsepower outboards are evolving with the arrival in Italy of the all-new Suzuki DF350AMD and DF300BMD. Suzuki’s two top-of-the-line models, in addition to the characteristic counter-rotating double propeller, now introduce engine-integrated steering and for the new technology foot. They arrived for the first time at the Genoa 2022 Boat Show.
Suzuki DF350AMD and DF300BMD arrive.
Regarded by many as the “4x4s” of the sea, Suzuki’s 350- and 300-horsepower outboards are among the most popular models on the market. Their double propeller has always been their strong point both in sailing and maneuvering because it provides great grip on the water. Hence the definition of “4×4” was born, to which a whole series of new features are now added.
Suzuki DF350AMD and DF300BMD – What’s New
What’s new? The first new features are first of all the wheelhouse integrated directly into the engine and the foot, the submerged part of the engine, renovated.
Suzuki DF350AMD and DF300BMD due to a less “bulky” gearbox see a refinement of the front of the foot by 4%. With this new line, friction with water decreases with two results: on the one hand, top speed increases by 2%, and on the other hand, at cruising speed, fuel consumption is reduced.
The other new feature is the optional Steer by Wire wheelhouse, which includes the new dedicated joystick with a system for automatic rudder adjustment and assisted mooring function. This electrohydraulic wheelhouse is adaptable to all boats and, in addition to promising advantages in navigation and maneuvering, allows for “simplifying” the stern. Less footprint and less maintenance are always important elements on a powerboat.
When installing more than one engine, with the help of the Steer by Wire system, each outboard has its own built-in actuator, which allows it to be decoupled from the others. Simplified and by a great deal, then, all mooring and maneuvering operations with each engine moving independently, automatically, depending on where you want to go. In this respect Suzuki electronics play an important role by focusing on the fastest possible signal transmission to the engines. Ease of use of control systems is, in fact, central when navigating, particularly in the straits.
Suzuki DF350AMD and DF300BMD – Features
Suzuki DF350AMD and DF300BMD are the new 4390 cc V6 outboards with 350 and 300 horsepower, respectively. In the gearbox lubrication system, oil circulation has been improved and the amount of oil has been reduced from 3.2 to 2.8 liters. Important then is that the replacement no longer requires hauling the boat.
Features of these engines include then:
- the Dual Louver System: this is a dual filter consisting of blades in the grille, made in the shape of a dog’s paw. This allows some of the impurities to be removed from the intake air and, most importantly, limits the entry of moisture into the calender
- Direct Intake Systems are the newly designed and shaped intake ducts manage to lower the temperature of the air, making it denser and improving its qualities as an oxidizer in connection with the Lean Burn that we will see in a moment.
- Dual Injector, that is, dual injector technology takes advantage of two smaller injectors instead of the traditional ones for maximum performance. What does it mean? That injecting 100 percent gasoline in the right place at the right time (such as at a particular angle in the combustion chamber) improves engine performance.
- Suzuki Lean Burn is a great Suzuki classic, but we never tire of it. This lean-burn system uses a network of sensors that continuously analyze the engine according to various parameters: how hard they are struggling, what the temperature is outside, when they are pushing on the engines. Based on this, automatically, the amount of air and gasoline in the combustion chamber is managed so that there is always the right amount of air for combustion to be most efficient. This provides a fuel economy that, especially at constant speed, cruising, saves 14% fuel.
