SUZUKI 140 HP DF140ATL2 OUTBOARD MOTOR

Description

We have the Suzuki DF140ATL2 for sale new in the factory crate. It is Suzuki’s 140 horsepower inline 4 four stroke with a 20 inch shaft, power trim and tilt, electric start and remote steering, finished in Pearl Nebular Black. 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. The Suzuki DF140ATL2 for sale is covered here too.

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 DF140ATL2 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 DF140ATL2 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. T means power trim and tilt. L is a long shaft, for a 20 inch transom. 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, and there is no W, so the cowl is black. That is a big part of why people choose the Suzuki DF140ATL2 for sale.

Why People Like the Suzuki DF140ATL2 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.

There is a self-adjusting timing chain running in oil, so no belts to replace. Mechanical controls keep rigging simple. Owners of the Suzuki DF140ATL2 for sale tell us the same thing again and again.

Boats That Suit the Suzuki DF140ATL2 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 DF140ATL2 for sale Feels on the Water

The Suzuki DF140ATL2 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.

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. It is one of the reasons we keep the Suzuki DF140ATL2 for sale in stock.

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.

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. You get all of that with the Suzuki DF140ATL2 for sale.

Rigging the Suzuki DF140ATL2 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.

Transom Height and Shaft Length

The 20 inch long shaft suits most bay boats, bass boats, pontoons, aluminium boats and smaller centre consoles. Measure from the top of the transom to the bottom of the hull at the centreline before you order. If you get close to 20 inches, this is your motor. If it is nearer 25, you need the X shaft version. Ask us if you want photos of the Suzuki DF140ATL2 for sale before it ships.

Suzuki DF140ATL2 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 DF140ATL2 for sale is about 100 pounds lighter and revs higher. On light and mid weight boats it is often the smarter choice.

The People Who Order This Motor

We sell the Suzuki DF140ATL2 for sale to weekend boaters, full time fishermen, charter skippers and boat builders all over the world. What they have in common is that they want a new Suzuki with proper paperwork, delivered to their door at a clear price. That is what we do.

Day to Day Ownership

Good outboards fade into the background. You stop thinking about the engine and think about the fishing or the family instead. The Suzuki DF140ATL2 for sale starts on the first turn, idles cleanly with no choke and does not foul plugs after a slow morning. Keep up with flushing and servicing and it will keep doing that for years.

The First Ten Hours

New motors need a gentle start. For the first hour keep the Suzuki DF140ATL2 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.

Keeping the Suzuki DF140ATL2 for sale Healthy

Nothing about this motor needs special tools for routine care. Stick to a simple routine:

• After every trip: flush, rinse and check the tell-tale stream.
• Every month in use: look at the anodes, the prop and the fuel filter bowl.
• Every 100 hours or yearly: engine oil, oil filter, gear oil and a grease of every fitting.
• Every two years or so: water pump impeller and thermostat check.
• At the major service: plugs, fuel filter and a valve clearance check if the manual calls for it.

The timing chain runs in oil and does not need replacing like a belt. That is one less big bill to plan for. We are happy to answer questions about the Suzuki DF140ATL2 for sale by email or chat.

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.

What It Costs to Run

The light weight and Lean Burn control make the Suzuki DF140ATL2 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 DF140ATL2 for sale can be done by any decent marine mechanic or by a handy owner.

Keep the Fuel Clean

Most problems people blame on the engine start in the tank. Water, old fuel and dirt in the lines will make any motor run badly. Change the water separating filter every season, drain the bowl if you see water and use fresh fuel. In hot, humid places keep the tank as full as you can when the boat is parked, so there is less room for condensation. The Suzuki DF140ATL2 for sale handles this well.

Treat the fuel well and fuel injection rewards you with easy starts and smooth running.

Choosing a Propeller for the Suzuki DF140ATL2 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. This is where the Suzuki DF140ATL2 for sale earns its keep.

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. Plenty of buyers send us their boat details before ordering the Suzuki DF140ATL2 for sale, and we like that.

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.

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. Keep that in mind when you set up the Suzuki DF140ATL2 for sale.

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 DF140ATL2 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.

After a salt launch, rinse the trailer and the motor together and run the flush. It takes ten minutes and adds years. That applies to the Suzuki DF140ATL2 for sale as much as any motor.

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.

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. If you are unsure, send us a photo of the transom and we will check the Suzuki DF140ATL2 for sale is the right fit.

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.

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.

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.

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.

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.
