Suzuki 25 HP DF25ATHLW5 Outboard Motor

Description

The Suzuki DF25ATHLW5 for sale here is a new 25 HP Suzuki four stroke finished in white, with a 20 inch long shaft, tiller steering, power trim and tilt, and electric start backed up by a pull rope. It comes sealed in the Suzuki crate, the price is shown on this page, and we ship it worldwide once you have approved a delivery quote.

Mechanically the Suzuki DF25ATHLW5 for sale is the same motor as the dark DF25ATHL5. The difference is the paint. Suzuki calls the white finish Cool Test Gray, and on a white fibreglass skiff or a light grey RIB it simply looks right.

Why Choose the White Suzuki DF25ATHLW5 for Sale

We get this question a lot: is white just looks? Mostly, yes. But there are a few practical points that push people toward the Suzuki DF25ATHLW5 for sale.

• Matching the boat. A white motor on a white hull looks clean and can help resale on a well kept boat.
• Sun. A lighter cowl does not get as hot to the touch as a dark one when the boat sits in strong sun. The engine itself is water cooled either way, so this is about comfort when you grab the cowl, not engine temperature.
• Visibility of grime. Some owners like that white shows salt crust and oil stains early, so they clean more often.
• Fleet look. Charter and resort operators often run all white motors for a uniform fleet.

The trade off is that white shows scuffs and fuel stains more. A wipe with mild soap after each trip keeps it looking new. We also suggest a fitted cover if the Suzuki DF25ATHLW5 for sale lives outside.

What DF25ATHLW5 Stands For

• DF: Suzuki four stroke outboard
• 25: 25 horsepower, 18.4 kW
• A: the three cylinder battery-less EFI generation
• T: power trim and tilt
• H: tiller handle steering
• L: long shaft, 20 inches
• W: white, Suzuki’s Cool Test Gray colour
• 5: later production run of the same model

On the Suzuki power tilt tiller models, electric start is part of the package, so there is no separate E in the code. The Suzuki DF25ATHLW5 for sale starts on a button and keeps the recoil rope for emergencies.

Full Specs of the Suzuki DF25ATHLW5 for Sale

Because the engine, gearcase and tilt unit are shared with the dark model, every service part for the Suzuki DF25ATHLW5 for sale is the same, apart from the painted cowl panels.

Boats That Work Best with the Suzuki DF25ATHLW5 for Sale

You need a transom of about 20 inches and a boat rated for 25 HP. After that it comes down to taste and use.

Popular pairings

• White fibreglass skiffs and small centre-less fishing boats steered by tiller
• Grey or white RIBs with a long shaft transom
• Tenders on yachts where the owner wants the motor to match the topsides
• Painted aluminium boats in light colours
• Small sailboats with a long shaft bracket

When to pick something else

On a 15 inch transom, go for the short shaft version. If the boat has a wheel and console, a remote model such as the DF25ATLW5 is the right choice. If your hull is heavy and close to its weight limit, the 30 HP may be more comfortable.

Power Trim and Tilt on the Suzuki DF25ATHLW5 for Sale

The Suzuki DF25ATHLW5 for sale uses an electric pump and rams to move the motor. One switch handles both jobs.

Trim sets the angle of the motor while running. Trimmed in, the bow stays down and the boat climbs onto plane faster. Trimmed out, the bow lifts and the hull runs freer once you are up to speed. You adjust it while driving.

Tilt raises the motor out of the water for launching, beaching, mooring and trailering. No lifting, no reaching over the stern.

If the battery is flat with the motor up, a manual release valve lets you bring it down by hand. Close the valve again before running or the motor will not hold trim.

Inside the Suzuki DF25ATHLW5 for Sale

Fuel injection without a battery

The injection system runs on power from the flywheel. With a dead battery you lose the starter and tilt, but a pull on the rope still starts the Suzuki DF25ATHLW5 for sale and it runs normally.

Lean Burn

The ECU monitors running conditions and leans the mixture at steady speeds. Suzuki rated the A series up to 15 percent more efficient than the old carbureted DF25 in its own tests.

Three smooth cylinders

Most 25s in this class are twins. Three cylinders cut vibration, and Suzuki’s roller rocker arms and offset crank reduce friction inside.

Flush port

Clip a garden hose to the flush connector on the Suzuki DF25ATHLW5 for sale and run water through the cooling system with the motor off. Do it after every salt or muddy water trip.

How the Suzuki DF25ATHLW5 for Sale Feels to Drive

Press the start button with the motor in neutral and it fires within a second or two. The idle is soft and even. Three cylinders make a big difference here compared with the twin cylinder 25s many of our customers owned before.

Slide the shift lever into forward and the gear engages with a light clunk. Twist the grip and the EFI picks up cleanly. With the motor trimmed all the way in, a typical 14 to 16 foot skiff lifts onto plane quickly. Then a couple of taps on the trim switch and the bow settles, steering lightens, and speed creeps up a few notches.

At cruise the Suzuki DF25ATHLW5 for sale is quiet enough to talk over. At trolling speed it holds a low, steady rpm without loading up, which is what anglers care about.

Fuel use

Every boat is different, so take these as rough numbers from owners. Trolling burns very little, well under half a gallon an hour. An easy cruise runs about a gallon an hour. Full throttle uses roughly twice that. Lean Burn does most of its work at steady cruise.

Top speed

Speed depends on hull weight, shape, load and prop. A light 14 foot aluminium or fibreglass boat with two people commonly sees the 20s in mph. Heavier skiffs and loaded RIBs run slower. Send us your boat details and we will give you an honest estimate for the Suzuki DF25ATHLW5 for sale on your hull.

The Suzuki DF25ATHLW5 for Sale as a Yacht Tender Motor

A good share of the white 25s we ship go onto tenders carried by larger yachts. Owners want the motor to match white topsides and grey tubes. A few points from rigging these:

• Check whether the tender transom is 15 or 20 inches. Larger tenders often take the long shaft.
• Power tilt is a real help when the tender is hoisted on davits or a swim platform, since the motor can be raised clear without anyone leaning over the stern.
• Keep a small battery in the tender, sized for the starter. The 14 amp alternator keeps it charged while running.
• At around 163 lb the Suzuki DF25ATHLW5 for sale is light for a power tilt 25, which helps with davit weight limits. Check your davit rating with motor, fuel and battery on board.

Notes for Charter and Rental Fleets

Fleet operators like this model because guests do not need to pull start it. Push button starting, a single trim switch and a kill cord make the Suzuki DF25ATHLW5 for sale easy to hand over to someone new to boats.

• Fit throttle friction so the motor does not race if a guest lets go of the grip.
• Brief every guest on the kill cord.
• Log hours and service on schedule. Rental motors pile up hours fast.
• Keep a spare prop for each motor. Rental props get hit.
• Matching white motors across a fleet looks professional and helps resale when you rotate boats.

Commercial use often carries a different warranty term from private use, so tell us if the motors will work in a fleet.

Rigging the Suzuki DF25ATHLW5 for Sale

Tiller rigging is simple. Here is what you need on top of the Suzuki DF25ATHLW5 for sale itself:

• A marine starting battery, about 500 to 650 CCA, in a strapped down box
• Through bolts and sealant for the transom bracket
• A transom saver if you trailer
• A cover, especially on a white motor that lives outdoors
• An inline water separating fuel filter if you use a built-in tank

No control box, no cables, no gauges. The tiller does it all. That keeps the total cost of the Suzuki DF25ATHLW5 for sale package well below a remote steer setup with the same features.

Getting the prop right

At full throttle with your usual load, aim for 5,000 to 6,000 rpm. Below that, drop pitch. On the limiter, raise pitch. Light skiffs usually run the stock 11 pitch. Loaded RIBs often want a 9 or 10.

Fitting It to Your Transom

Two people can lift a tiller 25 onto a transom, though a small engine hoist makes it easier and safer. Centre the bracket, tighten the clamp screws, then drill and through bolt the bracket using marine sealant in every hole. Water getting into a wooden transom core through untreated bolt holes is how transoms rot.

Run the battery cables along the inside of the hull, clipped every foot or so, and keep them clear of the tilt bracket so they do not pinch when the motor swings up. Red goes to positive, black to negative. Check the tilt through its full travel with the boat on the trailer before the first launch.

If your transom feels soft when you press on it, or the old motor left cracked gelcoat around the bolts, get it checked first. A good mechanic can tell you in a few minutes if it needs work. Hanging a new Suzuki DF25ATHLW5 for sale on a weak transom is asking for trouble.

Shallow Water and Weed

Power tilt lets you lift the motor partly while idling over a sand bar or through a shallow channel. Go slow, watch the tell-tale, and lower the motor as soon as the water deepens. The cooling intake sits higher when tilted, so running fast in that position can starve the pump.

In weedy lakes and rivers, tilt up every so often and pull weed off the prop and gearcase. Fishing line wrapped behind the prop is another thing to check, since it can damage the prop shaft seal and let water into the gear oil. If the gear oil ever looks milky at a service, have the seals checked on the Suzuki DF25ATHLW5 for sale before it goes back in the water.

Measuring for a Long Shaft

Measure from the top of the transom at the centre down to the bottom of the hull. On a V hull, use a straight edge along the keel line. About 20 inches means the Suzuki DF25ATHLW5 for sale is the right length. About 15 inches means you want the DF25ATHSW5 short shaft white model instead.

Mount the motor with the anti-ventilation plate level with the hull bottom to begin with. Then test. Prop blowing out in turns means lower it. Lots of spray and drag means raise it.

Break-In for the Suzuki DF25ATHLW5 for Sale

1. 0 to 15 minutes: idle and slow in gear.
2. 15 to 60 minutes: under half throttle, around 3,000 rpm max, change speed often.
3. 1 to 2 hours: up to three quarter throttle, short full throttle bursts are fine.
4. 2 to 10 hours: normal use, no long full throttle runs.

Do the first service on the Suzuki DF25ATHLW5 for sale at 20 hours or one month. Oil and gear oil out, fresh in. It is cheap and it matters.

Maintenance Schedule for the Suzuki DF25ATHLW5 for Sale

Use genuine parts from the Suzuki genuine parts and accessories catalogue. We can include a first service kit with your order.

Keeping the White Finish Looking New

White Suzukis look great when clean. A few habits keep the Suzuki DF25ATHLW5 for sale that way:

• Rinse the cowl and leg with fresh water after every trip.
• Wipe exhaust soot off the leg before it bakes on. A soft cloth and mild boat soap is enough.
• Wax the cowl with a marine UV protectant wax a few times a year.
• Use a breathable cover. Plastic sheets trap moisture.
• Clean fuel spills at once. Fuel can stain the paint.
• Touch up stone chips on the leg with Suzuki touch-up paint to stop corrosion starting.

Salt Water Habits

The Suzuki DF25ATHLW5 for sale is fine in salt water, provided you look after it.

• Flush with fresh water 10 to 15 minutes after each salt trip.
• Tilt the motor up on the mooring.
• Spray the bracket, tilt rams and electrical plugs with corrosion guard.
• Inspect and replace anodes when half used. Do not paint them.
• Keep battery terminals clean and greased.

Laying Up for the Off Season

1. Treat the fuel with stabiliser and run the Suzuki DF25ATHLW5 for sale for ten minutes.
2. Change engine oil and gear oil before storage.
3. Flush the cooling system with fresh water.
4. Grease the bracket and swivel.
5. Wash, dry and wax the white cowl.
6. Store it trimmed down with the rams retracted.
7. Take the battery out and keep it on a smart charger.

A Small Kit Worth Carrying

We suggest a zip bag with a spare prop nut and cotter pin, a spark plug and plug spanner, a spare kill cord, a few fuses for the tilt circuit, and a short piece of fuel hose with two clamps. Add a small torch and a multi tool. With that, most small faults on the Suzuki DF25ATHLW5 for sale can be sorted on the water.

Problems Owners Run Into with the Suzuki DF25ATHLW5 for Sale

Tilt does nothing

Low battery, blown fuse or a corroded plug. Check those three in that order.

Motor sinks slowly from trimmed out

The manual release valve is probably not fully closed.

Clicking, no crank

Weak battery or loose terminal. Pull start the Suzuki DF25ATHLW5 for sale and deal with the battery at home.

Weak water stream

Clear the tell-tale hole. If still weak, check the intake for debris and then the impeller.

Yellowing or chalky cowl

Sun and neglect. Polish with a fine marine cleaner wax, then protect it.
