SUZUKI 140 HP DF140A OUTBOARD MOTOR

Description

We have the Suzuki DF140A for sale new in the factory crate. It is Suzuki’s 140 horsepower inline 4 four stroke with a 20 or 25 inch shaft, power trim and tilt, electric start and remote steering, finished in Pearl Nebular Black or Cool White. It suits bay boats, aluminium fishing boats, pontoons and small centre consoles that want good power for the weight.

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. That applies to the Suzuki DF140A for sale as much as any motor.

We put everything on this one page: specifications, the model code, boats it suits, how it runs, rigging, care, shipping and an FAQ at the end. Read what you need and skip the rest.

Suzuki DF140A 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 140 HP page on Suzuki Marine if you want to compare models side by side.

What the Model Code on the Suzuki DF140A for sale Means

Suzuki model codes look confusing until someone explains them once. DF is Suzuki’s four stroke prefix and 140 is the horsepower. The A marks the A generation of this engine. This listing uses the short model name, so we confirm the full order code, shaft length, colour and rotation with you before the Suzuki DF140A for sale ships.

Why People Like the Suzuki DF140A for sale

Suzuki’s 140 sits in a sweet spot. It uses the 2.0 litre inline four from the 115, revs a little higher and makes 140 horsepower while weighing around 410 pounds on the L shaft. That is light for the power.

Lean Burn control trims fuel at cruise. The offset driveshaft moves the weight forward, and the two stage gear reduction gives a 2.59:1 ratio so the motor can swing a decent sized prop. If you are unsure, send us a photo of the transom and we will check the Suzuki DF140A for sale is the right fit.

There is a self-adjusting timing chain running in oil, so no belts to replace. Mechanical controls keep rigging simple.

Boats That Suit the Suzuki DF140A for sale

Bay boats and flats boats

Light hulls in the 17 to 20 foot range fly with a 140.

Bass and multi species boats

A popular choice for boats rated around 140 to 150.

Pontoons

Mid size pontoons get good performance with less weight on the stern.

Aluminium boats

Deep V aluminium boats rated for 140 are a classic fit.

How the Suzuki DF140A for sale Feels on the Water

The Suzuki DF140A for sale feels lively. It revs freely and pushes light and mid weight boats hard.

It is also smooth and quiet at low speed, which matters on long idles out of the harbour. Many repeat customers come back for a second Suzuki DF140A for sale on another boat.

Single or Twin Installs

On a single engine boat, this standard rotation model is all you need. For a twin setup you would normally pair it with the counter rotating Z version so the props turn in opposite directions and the boat runs straight.

If you are building a twin rig, tell us when you order and we will match the two motors so the serial numbers, gearcases and paperwork line up. The Suzuki DF140A for sale is covered here too.

Colour and Finish

Black is the standard Suzuki finish and suits almost any boat. If you want a white cowl to match a white hull, ask us about the W version of this motor. The engine underneath is the same.

Rigging the Suzuki DF140A for sale

This is a remote model. You will need a control box with throttle and shift cables, a steering system rated for 140 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.

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, 40 amp alternator keeps electronics charged on a normal day. That is a big part of why people choose the Suzuki DF140A for sale.

Transom Height and Shaft Length

This motor comes in more than one shaft length: L (20 inch) or X (25 inch). Measure from the top of the transom to the bottom of the hull at the centreline, send us the number and we will match the shaft. Getting this right is the single most important part of ordering an outboard.

Suzuki DF140A for sale or a 150?

Suzuki’s 150 is a much bigger engine at around 510 pounds. It has more torque for heavy boats.

The Suzuki DF140A for sale is about 100 pounds lighter and revs higher. On light and mid weight boats it is often the smarter choice.

Who Buys the Suzuki DF140A 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 DF140A 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.

The First Ten Hours

New motors need a gentle start. For the first hour keep the Suzuki DF140A for sale below half throttle and keep changing speed. After that you can use more throttle in short bursts. Avoid long runs at wide open throttle until the break-in period in the manual is done.

Book the first service on time. Fresh engine oil, a new filter and fresh gear oil set the motor up for the long run. Owners of the Suzuki DF140A for sale tell us the same thing again and again.

Maintenance on the Suzuki DF140A for sale

Servicing a Suzuki inline four 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 and grease the tilt and steering points 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.

Is 140 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 140 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. It is one of the reasons we keep the Suzuki DF140A for sale in stock.

What It Costs to Run

The light weight and Lean Burn control make the Suzuki DF140A for sale economical at cruise. Your boat decides the real numbers.

Servicing is not expensive either. Suzuki parts are widely stocked, and most routine jobs on the Suzuki DF140A 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.

A fuel stabiliser in the tank before a lay up is cheap insurance. You get all of that with the Suzuki DF140A for sale.

Choosing a Propeller for the Suzuki DF140A for sale

The right prop lets the motor reach its full throttle range of 5,600 to 6,200 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 15 to 26 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.

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. Ask us if you want photos of the Suzuki DF140A for sale before it ships.

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.

Batteries and Wiring

Use a marine starting battery with good cranking amps, keep the terminals clean and tight and fit a battery switch. If you run lots of electronics, a second house battery with a charging relay keeps the starting battery fresh. Corrosion on terminals and loose earth wires cause more no-start calls than anything inside the engine. We are happy to answer questions about the Suzuki DF140A for sale by email or chat.

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.

Running in Tropical or Cold Water

Tropical boaters should check the impeller more often and keep an eye on the cooling stream, because warm water with sand or silt wears pumps faster. In cold regions the Suzuki DF140A for sale starts easily with its fuel injection, but always store it upright and drained before freezing weather.

Trailering and Launching

If the boat lives on a trailer, tilt the motor up for the road and fit a transom saver or motor support so the bumps are not taken by the tilt system. Check the skeg clears the road on steep driveways. At the ramp, lower the motor fully before you start it, and never run it out of the water. A quick look at the cooling stream once it is running costs nothing and saves a lot. The Suzuki DF140A for sale handles this well.

After a salt launch, rinse the trailer and the motor together and run the flush. It takes ten minutes and adds years.

Storage Between Trips

After the last run of the day, flush the motor and let it drain in the down position, then tilt it up. If it will sit for weeks, disconnect the battery or put it on a maintainer. For long storage, stabilise the fuel, change the oil, grease the steering and tilt points and fit a cover. This is where the Suzuki DF140A for sale earns its keep.

Common Problems and Quick Checks

Will not crank. Check the kill switch lanyard is clipped on, the lever is in neutral and the battery terminals are clean and tight.

Cranks but will not start. Squeeze the primer bulb until it is firm, open the tank vent and drain any water from the separator bowl. Plenty of buyers send us their boat details before ordering the Suzuki DF140A for sale, and we like that.

Weak tell-tale stream. Clear the outlet with a bit of wire. If it is still weak, have the impeller checked before running hard.

Will not reach full revs. Usually the wrong prop or the motor mounted too low. Check the prop first. Keep that in mind when you set up the Suzuki DF140A for sale.

Warning buzzer. Slow down straight away, check the cooling stream and oil, and do not keep running with an alarm.

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 DF140A for sale as much as any motor.

Repowering an Older Boat

If you are swapping out an old motor, check the transom core around the bolt holes once it is off. Soft or wet wood has to be fixed before you hang a new engine on it. Look at the steering too. Weeping hydraulic rams and stiff cables should be replaced now, not after the first trip.

On the first run, watch the tell-tale, listen for anything odd and see how the boat sits. Adjust trim and mounting height until it runs level and the prop holds in turns.

Two Stroke to Four Stroke: What Changes

If your old motor was a two stroke, a few things will feel new. You will stop buying two stroke oil. The motor will idle cleanly without smoke. Fuel bills drop, often a lot, especially at cruise. You will also notice the extra weight on the transom, so set the trim and mounting height carefully on the first runs.

Service changes too. Instead of plugs and oil injection checks, you will be changing engine oil and filters like a car. It is simple, and most owners prefer it.

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.
