SUZUKI 25 HP DF25ATS2 OUTBOARD MOTOR

Description

The Suzuki DF25ATS2 for sale here is a new 25 HP Suzuki four stroke with remote steering, a 15 inch short shaft, electric start and power trim and tilt. It is the short shaft partner of the popular DF25ATL2, built for lower transoms on console boats. We sell it new in the factory crate, the price is listed on the page, and we ship worldwide.

Short shaft remote 25s are less common than long shaft ones, and that is exactly why people end up on this page. They have a small console boat with a 15 inch transom, they have looked around, and the right motor is hard to find. We keep this one listed because those boats are still out there in big numbers.

Boats that need the Suzuki DF25ATS2 for sale

A 15 inch transom is common on smaller hulls. These are the boats we usually see the Suzuki DF25ATS2 for sale go onto:

• Jon boats from 14 to 16 feet that have been fitted with a side console.
• Small aluminium V-hulls with a low transom and a steering console.
• Rigid inflatables and inflatable boats with a small console and a short shaft transom.
• Older fibreglass runabouts and dinghies built for 15 inch motors.
• Duck boats and mud boats with a console where the owner wants a wheel, not a tiller.

The common thread is a short transom and a steering wheel. If your boat has both, the Suzuki DF25ATS2 for sale is very likely the motor you need.

Why not just fit a long shaft?

We get this question a lot, usually because long shaft motors are easier to find. On a 15 inch transom, a long shaft hangs about 5 inches too deep. The gearcase and leg drag through the water, throwing spray and slowing the boat. Steering gets heavy. You burn more fuel for less speed. In shallow water you hit bottom sooner. It is the wrong fit, and we will tell you so before you buy.

And why not a tiller?

Some people with short transoms are happy with a tiller, and the DF25ATHS2 is a good motor for them. But once you have a console, sitting at the back to steer makes no sense. Weight distribution is better with the driver forward, the boat planes flatter, and you can see where you are going. That is why the Suzuki DF25ATS2 for sale exists.

The DF25ATS2 model code, decoded

Suzuki model codes are a short description of the motor. For the Suzuki DF25ATS2 for sale:

• DF: Suzuki four stroke.
• 25: 25 HP.
• A: the DF25A series, a 490 cc three cylinder with battery-less EFI.
• T: power trim and tilt.
• S: short shaft, 15 inches.
• 2: the series suffix used on this listing.

There is no H, so it is not a tiller model, and no W, so it is the standard dark Suzuki colour rather than white. The white version is the DF25ATSW2.

Suzuki DF25ATS2 for sale: the spec sheet

Figures for the Suzuki DF25ATS2 for sale, based on Suzuki published data and the factory sheet. Weight is approximate.

You can compare these with Suzuki’s current portable outboard line on the official Suzuki Marine outboards page.

What you get with this motor

EFI that does not depend on the battery

The DF25A was the first 25 HP outboard to run electronic fuel injection without a battery powering it. Once the engine is turning, it makes its own power for the EFI. The Suzuki DF25ATS2 for sale uses its battery to crank and to run the trim, but the injection keeps working even if the battery is tired.

For a console boat that sits at a dock or on a trailer between trips, EFI is the biggest improvement over the older carburetted 25s. No choke, no priming routine, no varnished carb jets. Key on, it starts.

Lean burn for lower fuel use

Lean burn control adjusts the mixture to match the load. Cruising, it runs lean. Asking for power, it richens up. The result is lower fuel use across a normal day. Buyers who move to the Suzuki DF25ATS2 for sale from an old two stroke often tell us their fuel bills fell sharply.

Smooth three cylinder

Three cylinders give a smoother idle and less vibration through the console and hull than a twin. You notice it most at trolling speed and when idling up to a dock. It is also quiet, which customers comment on more than anything else.

Power trim and tilt

Trim is on a switch on the remote control handle. On a small, light hull with a 15 inch transom, trim makes a real difference. Trim in to get up on plane. Trim out to lift the bow and gain speed. Tilt up for shallow water, the trailer, or mooring. A shallow water setting lets the Suzuki DF25ATS2 for sale run slowly with the leg partly raised.

Protection features

• Low oil pressure warning to alert you before damage.
• Over-rev limiter if the prop ventilates or comes out of the water.
• Freshwater flush connector.
• Suzuki anti-corrosion system on the leg and gearcase.
• Through hub exhaust, which keeps noise and fumes down.

Everything else you need for a remote install

The Suzuki DF25ATS2 for sale is the motor only. To run it from a console you need these parts too:

Genuine Suzuki controls, cables and gauges are on the Suzuki genuine parts and accessories pages. Send us your lengths and we can quote a full rigging package with the Suzuki DF25ATS2 for sale.

Getting cable lengths right

Lay a rope from the control, along the path the cables will take, to the centre of the motor. Add a little for the motor’s movement when steering and tilting. Round up to the next standard length. Too short and they bind. Too long and you have a loop to hide. Same method for the steering cable.

Prop selection

The spec sheet lists a 3 blade 10.25 x 11 aluminium prop. That suits many small hulls. If the Suzuki DF25ATS2 for sale goes past 6,000 rpm at full throttle, go up in pitch. If it will not reach 5,000, go down. Test with your usual load, not an empty boat.

Measuring the transom for a short shaft

1. Find the centre of the transom.
2. Measure from the top of the transom down to the bottom of the hull, following the slope of the transom.
3. About 15 inches: the Suzuki DF25ATS2 for sale is right.
4. About 20 inches: choose the long shaft DF25ATL2.

Once mounted, the anti-ventilation plate should be level with the bottom of the hull, or up to about an inch above it. A notched transom or a motor well changes things. If yours has one, send photos and we will check it.

Installing the Suzuki DF25ATS2 for sale step by step

A remote 25 is a reasonable home job if you are handy. If not, a marine mechanic will do it in a day. This is the order that works:

1. Inspect the transom. Press on it. Repair any soft or rotten wood first.
2. Hang the motor on the centre line and set the height.
3. Mark, drill and through bolt it with sealant in every hole.
4. Mount the control box on the console side.
5. Run throttle, shift and harness, with smooth bends, tied down so they cannot chafe.
6. Install the helm, steering cable and link arm.
7. Fit the battery, strapped down, with short cables.
8. Connect the fuel system and squeeze the bulb firm.
9. Adjust the cables so throttle opens fully and shift engages cleanly.
10. Check the motor will not crank in gear. Then test on muffs, then on the water.

Break-in for the first ten hours

A new Suzuki DF25ATS2 for sale needs a gentle start. The owner’s manual has the exact steps. In general:

• First 2 hours: low to moderate speed, below half throttle, varying the rpm.
• Third hour: up to about three quarters throttle.
• Hours 4 to 10: brief full throttle runs are fine, then ease off. Keep changing speed.

After that, do the first service. Engine oil and filter, gear oil, and a check of the control cable and steering adjustment. New cables settle in a bit.

Service schedule

Keep a log. A notebook with dates, hours and what was done is enough. It makes warranty claims on the Suzuki DF25ATS2 for sale far easier and helps when you sell the boat.

Salt water use

The Suzuki DF25ATS2 for sale is salt water rated. Suzuki’s anti-corrosion system protects the aluminium parts, but you still need to look after it:

• Flush after every salt trip through the flush port.
• Rinse the outside, the trim unit and the steering cable end.
• Tilt the motor up when the boat is moored.
• Replace anodes when they are about half gone.
• Grease the swivel and tilt fittings regularly.
• Spray the powerhead with corrosion guard every few months.

Inflatable owners in particular should rinse well. Salt collects in the folds around the transom and the motor clamps.

Common faults and simple fixes

Key turns, nothing happens

Control not in neutral is the usual cause. Then check battery charge, the terminals, and the main harness plug.

Starts, then dies

Often a fuel tank vent left closed or a pinched line. Open the vent and squeeze the bulb. If it keeps happening, check the fuel filter and the fuel itself.

Loses power at speed

Look for weed on the prop or water intake first. Then think about fuel. A blocked filter will starve the Suzuki DF25ATS2 for sale at full throttle but let it idle fine.

Prop blows out in turns

The motor may be mounted too high, or trimmed out too far. Lower it a hole or trim in. On a short transom, check it really is a 15 inch transom and not between sizes.

Repowering an older short transom boat

A lot of the Suzuki DF25ATS2 for sale orders we ship are repowers. The boat is fine, the old motor is tired. A few things to check before you swap:

Transom condition

Short transoms on older aluminium and fibreglass boats often have wood cores. Push on the top with the old motor tilted down. Any flex, cracking around bolts, or soft spots need repair before the new motor goes on. The Suzuki DF25ATS2 for sale is light, but no motor likes a weak transom.

Old controls

Controls and harnesses from other brands will not connect to the Suzuki DF25ATS2 for sale. Plan for a Suzuki control box and harness from the start. Steering helms and cables can often stay if they move freely and are in good condition.

Fuel system

Replace old fuel lines and primer bulbs. They break down inside and send debris to the injectors. Empty old fuel. Fit a water separating filter if the boat does not have one. It is cheap insurance for an EFI motor.

Steering effort

Older boats sometimes have stiff steering cables. A new motor does not fix a seized cable. Disconnect it and see if it moves freely. If not, replace it while the boat is apart.

Trailering and storage

Support the motor on the trailer with a transom saver or the tilt support. Long, bumpy drives with the weight hanging on the trim rams wear them out. On a small boat with a low transom, also check the skeg clears the road when tilted.

For a winter layup, stabilise the fuel and run the Suzuki DF25ATS2 for sale long enough for treated fuel to reach the injectors. Change the oil. Grease all fittings. Put the battery on a maintainer. Store the motor upright, or in the position the manual shows, with a breathable cover.

In spring, check for nests in the cowl, charge the battery, squeeze the primer bulb and run it on muffs. Watch the tell-tale before you head out.

Questions buyers ask us before ordering

Over the years the same questions come up about the Suzuki DF25ATS2 for sale. Here are the ones not covered in the FAQ below.

Can I add a tachometer later?

Yes. The harness and control setup allow gauges to be added. We still recommend fitting a tach at install, because you need it to check the prop.

Will it fit a boat that had a two stroke 25?

Usually, yes. The Suzuki DF25ATS2 for sale is a bit heavier than an old two stroke 25 but well within what a 25 HP rated boat should handle. Check the capacity plate for the motor weight limit.

Can I run it in fresh water only?

Of course. Flush it anyway after muddy or sandy water. Silt in the cooling passages is as bad as salt over time.

Is there a version with a tiller and remote kit?

Not as one motor. If you might want to switch, talk to us before ordering and we will help you choose the Suzuki DF25ATS2 for sale or a tiller version based on how you use the boat.

Running costs and ownership

Fuel is the main cost of the Suzuki DF25ATS2 for sale. At cruise on a small light hull, it uses a few litres an hour thanks to lean burn. At full throttle it uses more, at trolling speed hardly any. Most owners find a 6 gallon tank lasts a full day.

Servicing is cheap and simple. Filters, plugs, impellers and anodes for the DF25A are common parts that Suzuki dealers stock around the world. Keep a spare set of plugs, an impeller, a fuel filter and a spare kill cord clip in the boat.

Resale is good too. Suzuki 25s are well known and a clean, serviced Suzuki DF25ATS2 for sale on a boat makes the boat easier to sell later.

How the Suzuki DF25ATS2 for sale compares

All versions are in our 25 HP Suzuki category. These are the closest relatives of the Suzuki DF25ATS2 for sale:

• Suzuki DF25ATSW2: same motor in white.
• Suzuki DF25ATS5: the later suffix listing in the same configuration. Ask which is in stock.
• Suzuki DF25ATL2: remote with power trim on a 20 inch long shaft.
• Suzuki DF25ATHS2: short shaft with power trim but tiller steering.
• Suzuki DF25AES2: short shaft tiller with electric start and manual tilt, a simpler and lighter option.
• Suzuki DF20ATS2: 20 HP remote short shaft for boats rated below 25 HP.
• Suzuki DF30ATL2: the 30 HP remote, on a long shaft, if your transom and rating allow it.

The DF20A, DF25A and DF30A share one 490 cc block, so weight and size are close. The tune and the price change. For a 15 inch transom rated for 25 HP, the Suzuki DF25ATS2 for sale is the natural pick.

Suzuki DF25ATS2 for sale: FAQ

Is the motor new?

Yes. Every Suzuki DF25ATS2 for sale we ship is new, never run, in its factory crate.

Does it come with controls?

No. Controls, cables and harness are separate. We can quote them with the motor.

Can I fit it to my inflatable?

If the inflatable has a console, a 15 inch transom and a 25 HP rating, yes. Check all three first.

Is there a pull start backup?

The remote models are designed around electric start. Keep the battery charged and check it before each trip. Ask us about the emergency starting provision in your quote.

How fast will it go?

That depends on your hull, weight and prop. On a light 14 foot hull with two people, low to mid 20s mph is typical. Heavier boats are slower.

Do you ship worldwide?

Yes. Send us your location and we will quote delivery before you pay anything.
