Suzuki 250 HP DF250SSTX2 Outboard Motor

Description

We have the Suzuki DF250SSTX2 for sale new in the factory crate. It is Suzuki’s 250 horsepower V6 Super Sport four stroke with a 25 inch shaft, power trim and tilt, electric start and remote steering, finished in Matte Black with SS graphics. If you run an offshore centre console, a big bay boat or a heavy cabin boat, this is the class of motor most owners end up choosing.

This is a new motor in the factory crate, sold by us and shipped to your country. Before you pay for freight you get a written delivery quote, so there are no surprises later. Keep that in mind when you set up the Suzuki DF250SSTX2 for sale.

Below you will find the full specs, what the model code means, the boats it suits, rigging, maintenance and the questions buyers ask us most. It is a long page on purpose. A motor like this is a serious purchase and most people want the details first.

Suzuki DF250SSTX2 for sale: Specifications

Numbers can move a little between production runs, so the paperwork in the crate is the final word. Suzuki keeps the current figures on its Suzuki V6 outboard range if you want to compare models side by side.

What the Model Code on the Suzuki DF250SSTX2 for sale Means

Suzuki model codes look confusing until someone explains them once. DF is Suzuki’s four stroke prefix and 250 is the horsepower. T means power trim and tilt. X is an extra long shaft, for a 25 inch transom. SS is Super Sport, Suzuki’s performance series with its own gearcase and finish. The 2 at the end is the series number in Suzuki’s order code.

What you do not see in the code matters too: there is no Z, so it is standard rotation. That applies to the Suzuki DF250SSTX2 for sale as much as any motor.

What Makes the Suzuki DF250SSTX2 for sale a Super Sport

Suzuki’s DF250SS was the first V6 four stroke built for performance boats rather than offshore cruisers. Bass boats, big flats boats, performance pontoons and ski boats were the target, and it caught on quickly.

The SS uses a slimmer, more hydrodynamic gearcase than the standard V6. Less drag through the water means more speed for the same power. Suzuki first developed that gearcase shape on the DF300, then carried it into the SS range. The motor runs a 2.08:1 final ratio and is happy at higher revs than the standard 250.

Under the cowl you get dual overhead cams, 24 valves, variable valve timing and multi-stage induction. The trim package and the matte black finish with SS graphics set it apart on the ramp. If you are unsure, send us a photo of the transom and we will check the Suzuki DF250SSTX2 for sale is the right fit.

The SS Gearcase

The lower unit on the Suzuki DF250SSTX2 for sale is narrower and smoother than the standard one. It slips through the water with less drag, which matters a lot at bass boat speeds. Pair it with a good stainless prop, set the height right and you will see the difference on the GPS.

Boats That Suit the Suzuki DF250SSTX2 for sale

Tournament bass boats

This is the main market. A 20 to 21 foot bass boat rated for 250 is the natural home for the Suzuki DF250SSTX2 for sale.

Big flats and bay boats

Lighter performance bay boats and flats boats get a quick hole shot and strong top speed.

Performance pontoons

Tritoon boats built for speed take advantage of the SS gearcase and the strong top end.

Ski and wakesport style boats

Owners who want hard pulls out of the water like the instant response.

How the Suzuki DF250SSTX2 for sale Feels on the Water

The Suzuki DF250SSTX2 for sale is all about holeshot and top end. Trim it down, push the throttle and a light boat jumps onto plane. Trim out and it keeps pulling.

Despite the attitude, it is still a Suzuki four stroke at heart. It idles cleanly, starts easily and does not foul plugs on slow days.

Single or Twin Installs

Almost every boat that runs the Suzuki DF250SSTX2 for sale runs it as a single motor. Bass boats, flats boats and fast pontoons are built around one outboard on a jack plate, and this motor is set up for exactly that job with standard rotation.

If you have an unusual twin setup in mind, talk to us first and we will check what is possible. Many repeat customers come back for a second Suzuki DF250SSTX2 for sale on another boat.

Colour and Finish

The SS finish is part of the appeal. The dark paint and SS graphics look sharp on a bass boat or a fast flats boat, and the finish sits over Suzuki’s anti-corrosion coating, so it is not just for looks.

Rigging the Suzuki DF250SSTX2 for sale

This is a remote model. You will need a control box with throttle and shift cables, a steering system rated for 250 HP (hydraulic is normal at this size), a key switch and harness, gauges, a good marine battery and a fuel system with a water separating filter.

We confirm the exact control setup of the unit in stock before you order, so you buy the right controls the first time. The Suzuki DF250SSTX2 for sale is covered here too.

Mount the motor so the anti-ventilation plate sits roughly level with the bottom of the hull, then fine tune after a test run. If the prop blows out in turns, drop it a hole. If there is a lot of spray and drag, raise it. The 12 V, 54 amp alternator keeps electronics charged on a normal day.

Transom Height and Shaft Length

The 25 inch shaft suits most offshore boats and centre consoles. Measure from the top of the transom to the bottom of the hull at the centreline before you order. Around 25 inches means the X shaft is right. Boats on an outboard bracket or with a deep notch may need a different length, so measure carefully. That is a big part of why people choose the Suzuki DF250SSTX2 for sale.

Suzuki DF250SSTX2 for sale or the Standard DF250?

The standard DF250 is built around heavier offshore hulls and long cruising days. It carries a regular gearcase and is set up for big props on heavy boats.

The Suzuki DF250SSTX2 for sale is for lighter, faster boats where top speed and holeshot matter most. If you run a bass boat or a fast bay boat, the SS is the one to buy. If you run offshore with a heavy load, choose the standard model.

Who Buys the Suzuki DF250SSTX2 for sale From Us

Most of our buyers are owners who want a reliable motor and a fair price without dealer games. Next come fishing and charter operators repowering a working boat, and then boat builders and dealers who need stock to rig new hulls. The feedback after a season is nearly always the same: it starts every time, it is easy on fuel compared with what they had, and it has needed nothing beyond normal servicing.

Living With the Suzuki DF250SSTX2 for sale

Owning this motor is mostly uneventful, and that is the point. Turn the key and it starts. Run your day, flush it, tilt it up and go home. With fuel injection there is no carburettor to gum up if the boat sits for a few weeks, and it behaves the same on a cold morning as on a hot afternoon.

Breaking In the Suzuki DF250SSTX2 for sale

Follow the break-in in the owner’s manual. In short: vary the revs during the first hours, do not hold it at full throttle for long, and change the engine oil and filter at the first service. A motor broken in gently uses less oil and runs smoother for the rest of its life.

Give the gearcase its first oil change at that service too. It flushes out the fine metal from new gears bedding in.

Maintenance on the Suzuki DF250SSTX2 for sale

Servicing a Suzuki V6 is straightforward. Most owners handle the basics and let a mechanic do the bigger jobs.

• Flush with fresh water after every trip in salt or muddy water.
• Change engine oil and filter at the hours in the manual, or once a year.
• Change the gear oil every season. Milky oil means water is getting in.
• Replace anodes when they are about half gone.
• Replace the water pump impeller every couple of seasons, sooner in sandy water.
• Change the fuel filters and keep fuel fresh if the boat sits.
• Check plugs, the trim fluid and the thermostats at the service intervals.

The motor warns you about overheating and low oil pressure, and Suzuki fits an over-rev limiter. Treat it well and it will put in many thousands of hours. Owners of the Suzuki DF250SSTX2 for sale tell us the same thing again and again.

Is 250 Horsepower Right for Your Boat?

Start with the capacity plate on your boat. It gives the maximum horsepower and the maximum weight the transom is built for. Most owners do well with a motor at or near the maximum rating, because a motor that is not working flat out lasts longer and uses less fuel at cruise. If your boat is rated well below 250 HP, do not go over the plate. If you are unsure, send us the make, model and length and we will check it for you.

What It Costs to Run

Performance boats burn what they burn at wide open throttle, but at cruise the Suzuki DF250SSTX2 for sale is a frugal four stroke. Your hull, prop and right hand decide the real numbers.

Servicing is not expensive either. Suzuki parts are widely stocked, and most routine jobs on the Suzuki DF250SSTX2 for sale can be done by any decent marine mechanic or by a handy owner.

Fuel Quality Matters

Modern fuel injected motors are very reliable, but they do not like bad fuel. Buy from busy fuel stations, keep the tank vent clean and fit a good water separating filter between the tank and the motor. If your fuel contains ethanol, do not let it sit for months. Ethanol pulls in water, and water in fuel is the most common cause of rough running we hear about. It is one of the reasons we keep the Suzuki DF250SSTX2 for sale in stock.

A fuel stabiliser in the tank before a lay up is cheap insurance.

Choosing a Propeller for the Suzuki DF250SSTX2 for sale

The right prop lets the motor reach its full throttle range of 5,300 to 6,300 rpm with your normal load aboard. If it over revs, go up in pitch. If it cannot get into the range, come down. Suzuki lists a 17 to 30 inch pitch range for this motor.

Suzuki’s own props are a good match, and the Suzuki genuine parts and accessories range also covers filters, anodes and service kits. Or tell us your boat and load and we will suggest a starting prop. You get all of that with the Suzuki DF250SSTX2 for sale.

Running Slow All Day

Anglers spend a lot of time at idle or just above it. A fuel injected four stroke handles that well. There is no smoke, no oil fouling and no hard restart after a long drift. Keep an eye on the battery if you run a lot of electronics at low revs, and give the motor a short run at higher revs on the way home to clear it out.

Gauges and Electronics

You can run simple analogue gauges or Suzuki’s multi-function digital gauges, which show rpm, trim, fuel flow, hours and warnings on one screen. Many owners also network the motor into their chartplotter. Keep engine wiring separate from accessory wiring, fuse everything and use marine grade connectors. Ask us if you want photos of the Suzuki DF250SSTX2 for sale before it ships.

Getting the Electrics Right

A strong battery and clean connections are half the battle. Choose a marine cranking battery that meets or beats the motor’s requirement, crimp and heat shrink every connection and keep the battery secured in a box. A battery switch and a second battery for the electronics make long days much less stressful.

Looking After It in Salt Water

Fresh water flushing after every trip is the most important habit you can have. Use the flush port with a garden hose, rinse the outside and check the anodes regularly. On a mooring, keep the motor tilted up between trips so the gearcase is not sitting in the water. We are happy to answer questions about the Suzuki DF250SSTX2 for sale by email or chat.

Hot and Cold Climates

In hot climates, check the tell-tale stream often and keep the cooling passages clean. Warm, silty water is hard on impellers. In cold climates, fuel injection makes starting easy, but drain the motor and winterise it properly before a freeze.

Towing and Ramp Habits

Long road trips are harder on an outboard than most people think. Use a motor support bracket rather than resting the motor on the tilt ram, and check the bolts on the transom clamp or mounting after the first few trips. At the ramp, back in, lower the motor, start it in the water and watch for the tell-tale before you drive off the trailer. The Suzuki DF250SSTX2 for sale handles this well.

Back home, flush it while you wash the boat. Same routine every time and it becomes second nature.

Laying It Up

For short breaks, flush, drain and tilt up. For a long lay up, run stabilised fuel through the system, change the engine and gear oil, fog the engine if the manual calls for it, grease every fitting and keep the battery charged. A cover keeps sun and bird mess off the cowl. This is where the Suzuki DF250SSTX2 for sale earns its keep.

Simple Fixes Before You Call a Mechanic

No crank: lanyard clipped on, lever in neutral, battery charged, terminals tight.

Hard starting: firm primer bulb, tank vent open, no water in the separator, fresh fuel. Plenty of buyers send us their boat details before ordering the Suzuki DF250SSTX2 for sale, and we like that.

Overheat alarm: stop, tilt up and look for a plastic bag or weed over the intake. Check the tell-tale stream when you restart.

Low top speed: check the prop for damage, check the mounting height and make sure the boat bottom is clean. Keep that in mind when you set up the Suzuki DF250SSTX2 for sale.

Rough running: old fuel and dirty filters cause most of it. Start there.

Safety Gear Worth Carrying

Clip the kill switch lanyard on every time you run. Carry a spare lanyard, a basic tool kit, a spare prop and prop nut, a spare fuel filter, a VHF radio and a way to call for help. None of it costs much, and any of it can save a day on the water. That applies to the Suzuki DF250SSTX2 for sale as much as any motor.

Tips for a Repower

A repower is the best chance you will get to fix the things you cannot reach with a motor on the back. Check the transom, replace old fuel hoses and the primer bulb, clean or replace the tank pickup and fit a new water separating filter. Fresh fuel lines and clean fuel make a new motor happy from the first day.

Measure the transom height before ordering so the shaft length is right. It is the one mistake that is hard to fix later.

Coming From an Old Two Stroke

A lot of our buyers are replacing a two stroke that has done its time. The difference is bigger than most expect. No oil to mix or top up, no blue smoke at the dock, far less noise and a big drop in fuel use at cruise. The four stroke is heavier than an old two stroke of the same power, so check the capacity plate and how the boat sits once it is fitted. Most owners find the trade is well worth it after the first few trips.

Expect a different sound too. A four stroke is quieter and smoother, and some people keep looking back to check it is still running.

Mistakes We See Buyers Make

The most common one is the wrong shaft length. Measure the transom before ordering, not after the crate arrives. The second is under-propping, which lets the motor over rev and wastes fuel. The third is skipping the rigging list, then finding out the old controls or harness do not fit the new motor. And the last is ignoring the boat’s capacity plate. A motor heavier or more powerful than the hull is rated for is a real safety problem.

What a Typical First Season Looks Like

Most owners do the break-in over the first few weekends, then the first service. After that it is simply using the boat: run it, flush it, tilt it up. Around the middle of the season it is worth checking the anodes and the prop for dings. At the end of the season comes the lay up service with oil, gear oil and a grease. That is honestly all most people need to do in year one.
