SUZUKI 115 HP DF115ATX OUTBOARD MOTOR

Description

We have the Suzuki DF115ATX for sale new in the factory crate. It is Suzuki’s 115 horsepower inline 4 four stroke with a 25 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.

We sell new outboards to private owners, fishing operators, boat builders and dealers, and we ship worldwide. Tell us where your boat is and we send you a delivery quote before you commit to anything. The Suzuki DF115ATX for sale handles this well.

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 DF115ATX 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 115 HP page on Suzuki Marine if you want to compare models side by side.

What the Model Code on the Suzuki DF115ATX for sale Means

Suzuki model codes look confusing until someone explains them once. DF is Suzuki’s four stroke prefix and 115 is the horsepower. The A marks the A generation of this engine. T means power trim and tilt. X is an extra long shaft, for a 25 inch transom. There is no series number on the end, which marks an earlier production code. We confirm the build details of the unit in stock with you.

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. This is where the Suzuki DF115ATX for sale earns its keep.

Why the Suzuki DF115ATX for sale Is Such a Popular 115

The DF115A uses a 2.0 litre inline four with dual overhead cams and 16 valves. For a 115 that is a healthy displacement, and it gives good torque without much weight. On the L shaft it comes in around 400 pounds.

Suzuki Lean Burn control trims fuel at cruise. The offset driveshaft moves weight forward and keeps the motor compact, and the two stage gear reduction gives a 2.59:1 ratio so the motor can turn a bigger prop than most 115s.

A self-adjusting timing chain runs in oil, there is an over-rev limiter and a low oil pressure warning, and Suzuki’s anti-corrosion finish protects the outside. Plenty of buyers send us their boat details before ordering the Suzuki DF115ATX for sale, and we like that.

Boats That Suit the Suzuki DF115ATX for sale

Aluminium fishing boats

Deep V boats from 16 to 19 feet are a classic match.

Bay and flats boats

Light hulls run very well on a 115.

Pontoons

Mid size pontoons and tritoons rated for 115.

Small centre consoles

17 to 19 foot centre consoles.

How the Suzuki DF115ATX for sale Feels on the Water

The Suzuki DF115ATX for sale is smooth and quiet at idle and at low speed.

It has good hole shot for a 115 thanks to the gearing, and it cruises easily.

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. Keep that in mind when you set up the Suzuki DF115ATX 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

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. That applies to the Suzuki DF115ATX for sale as much as any motor.

Rigging the Suzuki DF115ATX for sale

This is a remote model. You will need a control box with throttle and shift cables, a steering system rated for 115 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 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. If you are unsure, send us a photo of the transom and we will check the Suzuki DF115ATX for sale is the right fit.

Suzuki DF115ATX for sale or the DF140A?

The DF140A uses the same engine with higher revs and more power for about the same weight.

The Suzuki DF115ATX for sale is the right choice when your boat is rated for 115 or when you want a little more economy.

The People Who Order This Motor

We sell the Suzuki DF115ATX 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 DF115ATX 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 DF115ATX 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 DF115ATX 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. Many repeat customers come back for a second Suzuki DF115ATX for sale on another boat.

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 115 HP, ask us and we will point you to a better match.

Fuel Use and Running Costs

The Suzuki DF115ATX for sale is easy on fuel at cruise thanks to Lean Burn. Real burn depends on your boat.

Parts are easy to find in most countries because Suzuki sells a lot of outboards. Filters, impellers, anodes and plugs are normal stock items. That keeps the long term cost of owning the Suzuki DF115ATX for sale sensible.

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. The Suzuki DF115ATX for sale is covered here too.

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

Getting the Prop Right

A motor is only as good as its prop. With the Suzuki DF115ATX for sale you want to land in the 5,000 to 6,000 rpm band at wide open throttle with a normal load. Too many revs means the pitch is too low. Too few means it is too high. The usual pitch choice for this motor is a 15 to 26 inch pitch range.

Look at Suzuki genuine parts and accessories for propellers and service parts, or ask us. We are happy to suggest a pitch if you send the boat make, length and typical load. That is a big part of why people choose the Suzuki DF115ATX 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.

Instruments for the Suzuki DF115ATX 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. Owners of the Suzuki DF115ATX for sale tell us the same thing again and again.

Salt Water Care

Flush after every salt trip. Rinse the outside, wipe salt off the cowl and spray a corrosion inhibitor under the cowl now and then. Suzuki’s anti-corrosion finish is tough, but salt finds any gap if you ignore it. If the boat lives in the water, tilt the motor up when you leave it.

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. It is one of the reasons we keep the Suzuki DF115ATX for sale in stock.

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. You get all of that with the Suzuki DF115ATX for sale.

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. Ask us if you want photos of the Suzuki DF115ATX for sale before it ships.

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. We are happy to answer questions about the Suzuki DF115ATX for sale by email or chat.

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. The Suzuki DF115ATX for sale handles this well.

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.

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.
