Suzuki DF140ATLW2 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 DF140ATLW2 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. W means the cowl is Cool White instead of black. 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. Owners of the Suzuki DF140ATLW2 for sale tell us the same thing again and again.

Why People Like the Suzuki DF140ATLW2 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. It is one of the reasons we keep the Suzuki DF140ATLW2 for sale in stock.

Boats That Suit the Suzuki DF140ATLW2 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 DF140ATLW2 for sale Feels on the Water

The Suzuki DF140ATLW2 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. You get all of that with the Suzuki DF140ATLW2 for sale.

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

This is the white version. Cool White looks clean on white hulls and stays cooler in the sun. Owners with white boats often say the motor just looks like it belongs. Under the paint it is identical to the black model. Ask us if you want photos of the Suzuki DF140ATLW2 for sale before it ships.

Rigging the Suzuki DF140ATLW2 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. We are happy to answer questions about the Suzuki DF140ATLW2 for sale by email or chat.

Suzuki DF140ATLW2 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 DF140ATLW2 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 DF140ATLW2 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.

Living With the Suzuki DF140ATLW2 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 DF140ATLW2 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 DF140ATLW2 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. The Suzuki DF140ATLW2 for sale handles this well.

Matching the Motor to the Boat

The right motor is the one your boat is rated for, carrying the load you normally carry. Check the capacity plate for maximum horsepower and engine weight, then think about how you use the boat. Heavy loads, rough water and long runs all favour running close to the maximum rating. Light boats and calm water give you more freedom. If the numbers do not line up with 140 HP, ask us and we will point you to a better match.

What It Costs to Run

The light weight and Lean Burn control make the Suzuki DF140ATLW2 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 DF140ATLW2 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. This is where the Suzuki DF140ATLW2 for sale earns its keep.

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

Choosing a Propeller for the Suzuki DF140ATLW2 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. Plenty of buyers send us their boat details before ordering the Suzuki DF140ATLW2 for sale, and we like that.

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.

Instruments for the Suzuki DF140ATLW2 for sale

Suzuki’s digital gauges read engine data straight from the motor, including fuel flow and service reminders. If you prefer, plain analogue tach and trim gauges work too. Whatever you fit, run tidy wiring with proper fuses. Good wiring now saves a lot of headaches later.

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. Keep that in mind when you set up the Suzuki DF140ATLW2 for sale.

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.

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. That applies to the Suzuki DF140ATLW2 for sale as much as any motor.

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.

Back home, flush it while you wash the boat. Same routine every time and it becomes second nature. If you are unsure, send us a photo of the transom and we will check the Suzuki DF140ATLW2 for sale is the right fit.

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.

Simple Fixes Before You Call a Mechanic

No crank: lanyard clipped on, lever in neutral, battery charged, terminals tight. Many repeat customers come back for a second Suzuki DF140ATLW2 for sale on another boat.

Hard starting: firm primer bulb, tank vent open, no water in the separator, fresh fuel.

Overheat alarm: stop, tilt up and look for a plastic bag or weed over the intake. Check the tell-tale stream when you restart. The Suzuki DF140ATLW2 for sale is covered here too.

Low top speed: check the prop for damage, check the mounting height and make sure the boat bottom is clean.

Rough running: old fuel and dirty filters cause most of it. Start there. That is a big part of why people choose the Suzuki DF140ATLW2 for sale.

Carry These on Board

A spare kill cord, a spare prop with nut and washer, a fuel filter, a couple of spanners, a radio and a torch. Add a tow line and an anchor that holds. It sounds basic, but most bad days on the water start with something small.

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. Owners of the Suzuki DF140ATLW2 for sale tell us the same thing again and again.

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

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.

The First Year of Ownership

Year one is easy. Follow the break-in, get the first service done on time and keep a log of hours. Look at the prop and anodes now and then, and flush after every salt trip. Before winter or a long break, do a proper lay up. If you do those simple things, the motor will reward you with years of trouble free running.
