Suzuki 25 HP DF25ATL5 Outboard Motor

Description

This page has the Suzuki DF25ATL5 for sale as a new motor in the factory crate. It is the 25 HP three cylinder Suzuki set up for remote steering, with a 20 inch long shaft, power trim and tilt and electric start, in the standard grey paint.

The price is listed on this page. We sell to buyers worldwide and send a full delivery quote before any payment. It’s the 25 we sell most often for small centre console boats, side consoles and aluminium runabouts where the driver sits forward at a wheel.

Reading the Suzuki DF25ATL5 for sale model code

Before anything else, check that the code matches your boat. One wrong letter means the wrong shaft or the wrong steering, and that’s an expensive mistake once a crate has crossed an ocean.

• DF means a Suzuki four stroke.
• 25 is the horsepower.
• A marks the DF25A generation: three cylinders, electronic fuel injection.
• T is power trim and tilt.
• No H, so there is no tiller. It is a remote control model, steered from a helm.
• L is long shaft, for a 20 inch transom.
• No W, so the paint is Suzuki’s standard grey.
• 5 is the catalogue suffix for this listing. The engine specs are the same DF25A.

So the Suzuki DF25ATL5 for sale is a long shaft remote motor. If you want white, that is the DF25ATLW5. If your transom is 15 inches, you want the DF25ATS5.

Which boats suit a 25 HP remote long shaft

The typical home for the Suzuki DF25ATL5 for sale is a boat between 14 and 17 feet with a steering console and a 20 inch transom. Mod V aluminium boats with a side console. Small fibreglass runabouts. Pontoon style boats in the smallest sizes. Sailing club safety boats. Small fishing boats that want a quiet motor and a wheel.

A remote motor moves the driver forward. That trims the boat better than sitting at the transom with a tiller, and it frees up the back for fishing or gear. On a 16 foot boat, that difference is huge. The bow comes down, the boat planes sooner, and you can see where you are going.

It is also popular with sailors. A sailboat with an outboard well or bracket and a 20 inch drop often runs a Suzuki DF25ATL5 for sale on remote controls led to the cockpit. Check the bracket rating for the weight first.

When a different 25 makes more sense

A 12 foot jon boat without a console doesn’t need remote steering. Buy a tiller. If you are not sure if your boat is long or short shaft, read the measuring section below before you decide on the Suzuki DF25ATL5 for sale.

Specifications of the Suzuki DF25ATL5 for sale

Figures come from Suzuki’s published DF25A data and dealer spec sheets. Weight is approximate.

What makes this motor good to live with

Smooth three cylinder powerhead

Competitors at 25 HP are mostly two cylinder motors. Suzuki went with three small cylinders. The result is less vibration through the hull and steering. On a console boat you notice it in the wheel, the windscreen and the gauge needles. They don’t shake.

Owners who come from an old carbureted twin often say the Suzuki DF25ATL5 for sale is so quiet at idle they check the tell tale to make sure it is running.

Fuel injection that doesn’t depend on the battery

Suzuki’s battery-less EFI generates its own power for the injectors and ECU once the motor turns. On the remote model you still need a battery to crank it, since there is no tiller to stand behind. But the motor keeps running fine if the battery is weak. And there is a recoil starter under the cowl for emergencies.

Lean burn at cruise

The ECU leans the mixture when the load is light. Run the Suzuki DF25ATL5 for sale at a steady cruise and fuel use drops compared with a carbureted 25. How much depends on hull and load. We have customers who run a full summer of weekend fishing on a few tanks.

Power trim from the control

The trim switch sits on the remote control handle. You trim with your thumb while driving. That is the right way to run a planing boat. Bow up a bit for speed in flat water, down for chop and hard acceleration.

You can compare the DF25A against the rest of the portable range on Suzuki’s outboard pages.

Rigging the Suzuki DF25ATL5 for sale

A remote motor needs more parts than a tiller. Plan them before the crate arrives so the boat is not sitting half done for weeks.

Parts list

• Remote control box: side mount with key switch, trim switch and neutral safety. Some market packages include one with the motor. We confirm in the quote.
• Throttle and shift cables: two cables, sized to your boat. Not included.
• Steering: a mechanical helm, wheel and steering cable, plus the link arm kit.
• Battery: 12V marine starting battery with a box and isolator switch.
• Fuel: tank, line with primer bulb, and ideally a water separating filter.
• Gauges: optional. A tachometer helps with prop selection.

Gauges worth adding

The motor runs fine with no gauges at all. The control box carries the warning buzzer for low oil pressure and overheating. Still, a tachometer is the one gauge we suggest for every console boat. It tells you whether the prop is right, and it lets you hold the same cruise rpm every trip, which makes fuel planning easy. A simple voltmeter is handy too, so you know the battery is charging. Ask us which Suzuki gauges work with the Suzuki DF25ATL5 for sale wiring loom before buying aftermarket ones.

Measuring cables

Measure from the centre of the control box, along the route the cable will take, to the centre of the motor where it connects. Add about 3 feet. Round up to the next whole foot. A cable that is too long is fine. One that is short is useless. We see that wrong all the time.

Mounting height and prop

Set the motor so the anti ventilation plate is level with or slightly above the hull bottom. Then run it and check rpm. The Suzuki DF25ATL5 for sale should reach 5,000 to 6,000 rpm at full throttle with a normal load. If it doesn’t, change pitch. One inch of pitch moves rpm about 150 to 200. Genuine props and rigging bits are listed under Suzuki genuine parts.

Real world use of the Suzuki DF25ATL5 for sale

Specs only tell part of the story. Here is how the motor gets used by the people who buy it from us, and what they report back after a season.

Small console fishing boats

This is the largest group. A 15 or 16 foot aluminium boat with a side console, a livewell and two people fishing. The Suzuki DF25ATL5 for sale planes the boat with two adults and a cooler, holds a steady cruise around the middle of the rpm range and idles slowly enough to drift a line past structure. Owners like that they can hear each other talk while running.

Club safety and coaching boats

Sailing and rowing clubs run their safety boats for hours at low speed, then sprint when someone capsizes. That pattern is hard on old carbureted motors, which load up and foul plugs. Fuel injection handles it far better. Several clubs we supply have moved their coach boats to the Suzuki DF25ATL5 for sale for that reason, and because the electric start means any volunteer can get it going.

Light work boats

Fish farm tenders, survey boats and harbour taxis use the 25 for short runs with a crew of two or three. For daily commercial use, the warranty terms change, so tell us when you ask for a quote. In heavy daily use, plan your services by hours, not by calendar.

Sailboat auxiliary

On a cruising sailboat with a long shaft bracket, the extra shaft length keeps the prop in the water when the stern lifts in a swell. A short shaft motor would cavitate there. The power trim helps you lift the Suzuki DF25ATL5 for sale clear when sailing, which cuts drag a lot.

Measure the transom before ordering the Suzuki DF25ATL5 for sale

Put a straight edge across the hull at the transom. Measure straight down from the top of the transom on the centre line to the bottom of the hull. Not along the slope.

• About 20 inches: long shaft. This motor is right.
• About 15 inches: short shaft. Look at the DF25ATS5.
• About 25 inches: extra long. That is not offered at 25 HP, so a bracket or a bigger motor is needed.

If you have a motor well, measure the well, not the outside transom. Send us a photo with the tape in it. We’ll confirm the Suzuki DF25ATL5 for sale is right before you pay.

Break-in

The owner’s manual asks for roughly 10 hours of break-in. Here is how we explain it to customers taking home a Suzuki DF25ATL5 for sale.

1. The first couple of hours: keep it at half throttle or less, and keep changing speed.
2. The third hour: up to around three quarter throttle. Short runs at full are fine.
3. Up to hour ten: use the full range but don’t hold wide open for long periods.
4. Watch the tell tale and the oil pressure warning every time.

Then do the first service on the Suzuki DF25ATL5 for sale. Oil, filter and gear oil. It costs little and sets the motor up for a long life.

Service intervals

The full schedule is in the manual. This is a quick reference for the Suzuki DF25ATL5 for sale in normal recreational use.

Remote motors need one more job: grease the steering cable and check the shift and throttle cable ends. A stiff cable makes the Suzuki DF25ATL5 for sale feel like it has a fault when it doesn’t.

Fuel and oil choices

The DF25A runs on regular unleaded. Suzuki lists a minimum of 87 AKI, which is 91 RON. You don’t need premium. What matters more is fresh fuel and clean fuel. Fit a water separating fuel filter between the tank and motor. In many parts of the world, fuel quality varies from one fill to the next, and a filter costs far less than an injector.

For oil, use Suzuki 10W-40 marine four stroke oil or a quality marine oil of the same grade that meets the spec in the manual. Car oil is not a good idea in a marine motor, because it lacks the corrosion additives. Gear oil should be a hypoid marine gear oil, filled from the bottom drain until it comes out the top vent. Ask and we can quote a first service kit to ship with the Suzuki DF25ATL5 for sale in the same crate.

Winter storage

If your boating season ends and the motor sits for months, prepare it properly. It takes an hour and saves a spring of headaches.

1. Add fuel stabiliser to the tank and run the motor for ten minutes so treated fuel reaches the injectors.
2. Flush with fresh water.
3. Change the engine oil and gear oil. Old oil holds acids that sit on bearings all winter.
4. Fog the cylinders if the manual calls for it, or follow the storage steps it lists.
5. Disconnect the battery and keep it charged.
6. Store the Suzuki DF25ATL5 for sale upright or tilted down, never with the powerhead lower than the lower unit.

Grease every fitting before storage too. Grease pushes out water and stops the swivel bracket seizing.

Looking after it in salt water

Salt kills outboards slowly. Fresh water stops it. The routine is short.

• Flush every trip, through the flush port or with muffs.
• Leave the motor tilted up when the boat is in the water overnight.
• Hose off the bracket, trim rams and steering arm.
• Check anodes each month in season.
• Spray corrosion guard on the powerhead under the cowl.
• Keep the steering cable greased, since salt seizes it.

A Suzuki DF25ATL5 for sale run in salt and treated this way will outlast one run in fresh water and ignored.

Problems we hear about and how to fix them

Won’t crank

On a remote model, check the control is in neutral. The neutral safety switch stops the starter in gear. Then check the lanyard clip is on and the battery is charged.

Hard to shift

On a new Suzuki DF25ATL5 for sale, it is almost always cable adjustment or a cable routed too tight. Check the bend radius and the adjustment at the motor end.

Rough running after the boat sat

Old fuel. Drain it, use fresh, and replace the fuel filter if it shows water. The Suzuki DF25ATL5 for sale has no float bowl to gum up, but injectors still hate stale fuel.

Steering pulls to one side

Adjust the trim tab under the cavitation plate. Turn it toward the side the wheel pulls to, a little at a time.

Overheat warning

If the Suzuki DF25ATL5 for sale sounds the alarm, look for weed on the intake or a worn impeller. Stop, tilt up, clear the intake. If the stream is still weak, plan an impeller change.

How the Suzuki DF25ATL5 for sale compares

Suzuki makes the DF25A in many versions. Here is how this one sits next to the ones customers often weigh it against.

• Suzuki DF25ATLW5: the same remote long shaft motor in white.
• Suzuki DF25ATS5: remote with power trim, but short shaft for 15 inch transoms.
• Suzuki DF25ATHL5: long shaft with power trim, but tiller steering.
• Suzuki DF30ATL5: the 30 HP remote long shaft on the same block.
• Suzuki DF20ATL5: the 20 HP remote long shaft, lighter on the wallet.
• Suzuki DF40ATL2: for when 25 or 30 is not enough.

All the 25s are in the 25 HP Suzuki category, and the full lineup sits under Suzuki outboards.

25 or 30?

The DF30ATL shares the block and the weight. It has more top end. If you load the boat with people and gear and it is rated for 30, buy the 30. For a light 14 to 16 foot boat with one or two people, the Suzuki DF25ATL5 for sale does the job and costs less.
