New 70-, 80-, and 90-Horsepower Models Lead a Fuel-Efficient Lineup of 4-Stroke Models, Expert Advice Can Help All Boaters Squeeze the Most Fun From Every Gallon

While fuel prices have come down from record highs seen during the summer of 2008, uncertainty about the
cost of gas — coupled with a tough overall economy — has undeniably kept people from using and enjoying
their boats as much as they could. That’s bad news, because it’s during times like these that people need the relaxation and release that comes from sharing time on the water with friends and family.

Fortunately, there’s good news. Today’s advanced 4-stroke outboards provide boaters with fuel economy and range beyond that would have been hard to imagine a few years ago. In Suzuki’s case, it’s been accomplished without sacrificing the acceleration, power and top-end speed boaters need to enjoy a full day on the water.
The new-for-2009 DF70, DF80 and DF90 are prime examples of how Suzuki has continuously improved its
4-stroke technology to create a new breed of outboard motors that are faster, lighter and more efficient. The
in-line 4-cylinder DF90, for example, is three inches shorter than the 4-stroke model it replaces, and at 341 pounds is the lightest 4-stroke in its class. And with features like a Dual Overhead Cam (DOHC) 16-valve powerhead, new Lean Burn Technology, new under cowl airflow design, two-stage gear reduction and a streamlined new gear case, these outboards set a new standard for efficient performance.

A test published in a leading national magazine reported that the DF90 achieved more than 9 mpg while
pushing an 18’ 4” Pro-Lite boat at more than 27 miles per hour — with two people aboard and a full tank of fuel. “When it’s possible to get better mileage from your boat than the tow vehicle you used to haul it to the ramp, that’s impressive,” said Larry Vandiver, Marketing Director for Suzuki Marine. “The Suzuki factory is committed to constant innovation and improvement, and this is being seen in our new generation of quicker, smaller and more efficient 4-stroke models. Our success stems from giving American boaters what they want. And what they
want today is to be able to take a few more casts or take one more dip with the family — without dipping into
their wallets.”

No matter what Suzuki 4-stroke outboard you run on your boat, the experts at Suzuki Marine offer these helpful tips to help people squeeze the most out of today’s tight boating budgets:

Get Properly Propped — The type, size and pitch of the propeller can have a big impact on performance, as
well as fuel efficiency. Too much pitch (measured in inches of forward movement per revolution) can result in poor hole shots, sluggish acceleration and overloading the motor. A prop with too little pitch will rob you of top end and possibly cause the motor to over-rev. Choosing the right prop (which is different for every boat/motor combination) will allow you to optimize performance and fuel efficiency. When “properly propped,” your engine should fall in the manufacturer’s recommended operating range (for example, 5,300-6,300 rpm with the DF90) when properly trimmed and running at wide open throttle. Suzuki offers a range of quality aluminum and/or stainless steel propellers engineered to deliver the best performance and fuel economy for a range of boats,
and your dealer can work with you to find the best one for your rig.

Get the Right Attitude — Adjusting the running attitude (using the motor’s trim adjustment and/or trim tabs)
can help every boat find its most comfortable, fuel-efficient ride. A boat that’s plowing through the water in a
bow-down attitude is like constantly driving your car uphill — it’s going to rob you of fuel efficiency. In contrast,
a boat that’s trimmed out too much will often “porpoise” or pound in rough water. Generally speaking, when your boat is riding smoothly and on the level, it’s riding efficiently.

Everything in Balance — Along with trimming your boat, be mindful of balancing your load. Where and how
you place passengers and gear (especially heavy items like batteries, ice chests, fishing tackle or dive tanks)
can affect the ride and efficiency of your boat. A properly balanced boat will remain level at rest, be easier to drive and consume less fuel at all speeds.

Know Your Sweet Spot — Every boat/motor combination has its own “sweet spot” — the engine rpm that delivers the best combination of speed and fuel efficiency. Many boats today come equipped with fuel management systems; there are also aftermarket ones available that make it easy to determine at what speed your boat operates at peak efficiency. Figure this out with your boat loaded the way you really use it — such as loaded down with gear, ice chests and fishing buddies.

Watch Your Weight — Hauling around a lot of stuff you don’t need can reduce your boat’s fuel efficiency significantly. Do a spring cleaning to remove extra gear that doesn’t get used. Speaking of weight, you’d be surprised how many anglers run back from the offshore grounds with bait tanks that are empty of bait but full of water. At more than eight pounds a gallon, this can add the equivalent of several full-sized people to your motor’s workload. Emptying the tanks for the run home will improve your efficiency and performance.

Easy Does It — If you’re not worried about beating the competition to a spot or racing back to make weigh-in with a tournament winning fish, don’t run flat out. Often the last few miles per hour you gain at full throttle come at high cost in increased fuel consumption. Better to leave yourself some extra time and travel at your boat’s optimum cruising speed.

Take Care — Properly maintaining your motor — especially changing engine oil, oil filters and fuel filters as recommended by the manufacturer — will keep everything running in tip-top condition and maximize fuel efficiency. If your boat stays in the water part or all of the year, stay on top of a clean bottom by removing algae, barnacles and other growth as this increases hull drag and lowers fuel efficiency. A good EPA-approved bottom paint, properly applied, can reduce growth from reoccurring.
