SUZUKI UNVEILS INDUSTRY’S FIRST 300HP V6 4-STROKE OUTBOARD


New 4-Litre V6 Powerhead, Streamlined Lower Unit and Electronic Throttle/Shift Control Highlight This Breakthrough in 4-Stroke Power and Performance

Suzuki Marine’s new DF300 proves that the most powerful 4-stroke outboard in the world can also be lightweight, compact and streamlined, making it the ideal power choice for an increasingly popular class of saltwater heavy hitters — offshore fishing boats, cruisers and power catamarans.

At 4.0 litres, this new engine offers the largest displacement of any V6 outboard ever made. The low-end grunt and torque to power heavily loaded offshore boats out of the hole is second to none. And the silky smooth acceleration keeps on climbing as you push the new electronic shift/throttle forward; right up until the boat reaches its eye-watering top end speeds.

Suzuki’s DF300 delivers all this power and performance in a package that fits with today’s modern fishing and performance boats. With a target weight of 274kg for the 25” shaft model (or 279kg for the 30” shaft), Suzuki’s 300-horsepower 4-stroke weighs about the same as other normally aspirated 250-horsepower models and considerably less than any supercharged 4-stroke 200 horsepower and up. And thanks to weight-saving features like new Alumite-coated forged aluminium pistons, which are attached to connecting rods with full float hollow wrist pins, Suzuki tips the scales in its favour, despite boasting considerably more displacement than the competition.

“With the advent of these large displacement 300hp 4-stroke outboards, many boat builders are now designing their boats to suit these fuel efficient engines,” said Haines Suzuki Marine General Manager, Greg Haines.



“Boat builders and the public are realising the advantage of outboard power; increased cockpit space, reliability, weight saving, fuel efficiency and ease of maintenance,” he added. “They are an attractive alternative to petrol or diesel inboard engines and we see the larger plate aluminium boats and power catamarans being well suited.”

The DF300 was designed with a narrow 55-degree V block. This narrow design allows for easy mounting of twin or triple installations on 26-inch centres without contact. Suzuki also uses its reliable offset driveshaft on the DF300, for better balance on the transom and an overall compact design.

For unsurpassed performance and fuel efficiency, Suzuki’s DF300 features a Dual Overhead Cam (DOHC) powerhead with four valves per cylinder. Suzuki’s proven Variable Valve Timing continually adjusts the intake cam phasing to maximize torque in the low- and mid-range. This feature also reduces emissions and improves fuel economy, a big plus for offshore tournament anglers who like to run fast and far in search of fish. Suzuki’s clean-running DF300 has met the Environmental Protection Agency (EPA) 2006 Federal emission standard and the California Air Resources Board (CARB) 3 - Star Ultra Low Emissions rating.

This breakthrough new outboard boasts other design features popularized on other advanced Suzuki 4-strokes, including computer controlled multi-point electronic fuel injection for optimum performance and a self-adjusting, oil bathed timing chain.

The DF300 also introduces several important firsts for Suzuki Marine, beginning with a sleek, aggressively designed new lower unit that reduces drag by 18 percent. This hydrodynamic lower unit works in conjunction with Suzuki’s proven two-stage gear reduction for an aggressive final drive ratio of 2.08:1. This low gear ratio means the DF300 can easily swing a 16-inch stainless steel propeller from 17- to 26-inch pitch, for optimum performance on wide a variety of hull shapes and styles. Counter rotation is available in both 25” and 30” shaft lengths for twin/triple engine configurations.

Newly configured air inlets feed an 81mm single throttle body for increased induction airflow. In another first, exhaust now flows unimpeded through the engine’s mid-section, as cooling water is routed through a separate track and expelled through a special vent above the propeller. These new intake and exhaust systems work together to improve the engine’s overall breathing for increased power output. And with a maximum operating range of 5,700 to 6,300 rpm, boaters can wind the DF300 up for exhilarating top-end performance.

Suzuki engineers know how important a full arsenal of sophisticated electronics is to today’s modern fisherman, so they’ve included a powerful 12V 54 Amp alternator that delivers plenty of juice to power up fishfinders, GPS chart plotters, radar systems, baitwell pumps, spreader lights and more. The DF300 also features a dual circuit charging system that can be adapted to accommodate the dual-battery configurations often used on large boats. The system is designed to charge both the cranking and house batteries simultaneously but on independent circuits. Boaters can drain their house battery running trolling motors, electronics or pumps and still have a fully charged cranking battery for starting the outboard motor.

The new DF300 is the first Suzuki to feature Suzuki Precision Control — an advanced fly-by-wire shift/throttle system designed for single or dual helm installation, with single, twin or triple engine rigging. This new electronic control provides many performance advantages over conventional systems, including smoother, more decisive shifting and quicker throttle response — especially important when manoeuvring in and out of tight spaces. Suzuki Precision Control also provides easy electronic synchronization of twin or triple engines for maximum engine efficiency while underway.

Additional features that make Suzuki’s new DF300 easy to use and maintain include push-button starting, new easy-to-use cowling latches and front and rear freshwater flushing ports, so you can keep the inside as clean as the outside.

The DF300 will be showcased by The Haines Group during this year’s boat show circuit, starting Melbourne 06-10 July with models available late 2006-early 2007.

Col - Do you think the electronic shift controls will make it down to the DF175s eventually ?

Cheers

Col,
Do you think you could modify the transom on my 450 Tiller to take one of these?

Greg.......Will have to find out for you.

Yeh captain for sure (not).. be good to see you hit the rocks with one of those on ;D ;D

Pedro...Twin 175's [smiley=2thumbsup.gif]

tim stole my thunder, was going to ask whether my transom would be rated to handle the big 300 on my 15 foot half cab.

on a more serious note, just wondering if any of the outboard manufacturers have considered a reverse prop\leg setup as is now on the volvo stern drive systems. could you see any benefits or detriments with that setup. i would like to see how it benefits outboard systems if at all.

have they managed any fuel flow figures as yet?
