Suzuki Announces New Lightweight And High Efficiency Four Cylinder Df200a
Variable Valve Timing is utilized on lots of Suzuki’s excessive-finish outboards to ship high performance across the outboard’s full powerband while retaining the benefits that 4-stroke expertise supplies. The system begins with an innovative cam profile designed for delivering most output and performance at high rpm. Variable Valve Timing is used to vary consumption timing with the camshaft to optimize timing for low to mid-vary operation. This permits the engine to ship most power output throughout its complete operating range producing greater low to mid-range torque for highly effective acceleration.
For a finances repower, I love the 200 Suzuki SS with its new gearcase, you cant’ beat the value and it should carry out very nicely with the right setup. When it involves flat out efficiency, The Merc has a slight RPM range benefit but the Yamaha is right there, it really comes all the way down to setup and desire, they’re so close. We need to throw both on a scale for actual world weight and do a aspect by aspect on the same hull, that’s the only way to know for positive. This mechanical collection delivers power like no different with its excessive gear ratio.
One Of The Best 300 Hp Outboard: No Contest
The V8 additionally shares the four.8” 1.85 as an possibility, which the V6 has normal. Both have water inlets on the entrance of the case for larger engine heights. The 200 HP range covers so much floor which is why we see so many various variations of the vary. Why do some producers go for a 4 cyl while Mercury has V6 and V8 200s?
Expect to pay a premium for the 4.2 V6 engine, that runs all the best way as much as 300 HP within the lineup. If you could have the finances, or find a nice used one, the 4.2 Yamaha is an excellent choice. With two choices in the 200 HP range, Yamaha does a great job of providing alternative and differentiation. Hard to beat, however not performance oriented, in fact you may go for the 175 SHO version as an alternative.
The Suzuki Lean Burn Control System is an intelligent gas delivery system that achieves remarkable improvements in gas consumption making gas-environment friendly four-stroke outboards much more economical. Monitoring engine performance and working conditions in real time, the system uses the 32-bit onboard ECM to foretell gas needs and ship a leaner, more exact fuel mixture throughout the outboard’s working range. The outcomes show important enhancements in gasoline economic system across the complete powerband, including the cruising vary where the engine is used a majority of the time. Comparing the new DF200SS with the unique V6 DF200, tests present up to a 19% increase in gasoline effectivity primarily in the cruising vary (round 70% of its maximum velocity). Getting the correct quantity of air into the cylinder has a fantastic impact on performance.
Suzuki pioneered the usage of digital gasoline injection in 4-stroke outboards with the launch of its unique DF70/60 in 1997. The system delivers improved gas economic system, crisp acceleration and reduced emissions that meet emissions laws. It additionally conforms to the Recreational Craft Directive Standards, Directive 2003/44EC of the European Parliament and of the Council, and has obtained a three-star ranking from the California Air Resource Board . Added to that are a gas injection system and Suzuki’s Lean Burn Technology for improved gasoline economy. In addition to the DF200A, Suzuki is also introducing the DF200AP, which benefits from even more know-how. The DF200AP will be the first 200 horsepower outboard available on the market out there with Keyless Ignition, Suzuki Precision Control drive-by-wire controls and Suzuki Selective Rotation.
Please confirm all monthly cost information with the dealership’s gross sales consultant. Your actual fee might differ primarily based on a number of factors such as down payment, credit history, last price, obtainable promotional packages and incentives. Applicable tag, title, destination charges, taxes and other fees and incentives usually are not included in this estimate.
Water-cooled voltage regulators included on both outboards dissipate heat in the regulator to boost durability. The battery charging system also incorporates an isolator function that enables the use of two batteries. The engine’s exhaust system is a well known supply of engine noise, however another, typically ignored source is the intake manifold.
Shorter and missing resistance, these pipes allow a higher quantity of air into the chamber, increasing the engine’s capacity to breathe efficiently at excessive rpm resulting in greater energy output throughout excessive-velocity operation. Suzuki’s revolutionary Lean Burn Control System was first introduced on the DF90A/80A/70A to nice acclaim from boaters and the media alike. It predicts gasoline needs according to operating situations permitting the engine to run on a extra environment friendly gasoline mixture through the use of a lean air-gas ratio. It delivers its benefits over a wide working vary, offering significant improvements in gasoline financial system from low-speed operation into the cruising range. Combining this technique with the Suzuki Precision Control electronic throttle and shift system permits the operator exact management over engine RPM for improved fuel economic system over a wider working range. This combination also delivers clean energy transitions throughout the entire RPM range.
