SUZUKI 25 HP DF25ATHLW2 OUTBOARD MOTOR

Description

We have the Suzuki DF25ATHLW2 for sale in stock: a new 25 HP tiller outboard in Suzuki’s white finish, with a 20 inch long shaft, electric start and power trim and tilt. It comes in the original factory crate. The price is on this page and we ship worldwide, with a delivery quote sent to you before any payment.

Mechanically it is the same motor as the dark DF25ATHL2. The difference is the colour. Plenty of our customers run white boats, centre consoles converted to tiller, or white hulled inflatables, and they want the motor to match. That is who usually orders the Suzuki DF25ATHLW2 for sale.

Decoding the Suzuki DF25ATHLW2 for sale

Suzuki model codes are logical once you know the pattern. For the Suzuki DF25ATHLW2 for sale:

Suzuki calls the white colour Cool Test Gray. In real life it reads as a clean, slightly warm white. It is not a decal or a wrap. The cowl and the lower panels are finished in that colour at the factory, with the same anti-corrosion layers underneath as the dark motors.

Why pick white over the standard colour

We get asked this a lot. There is no performance difference. The Suzuki DF25ATHLW2 for sale runs exactly like the dark version. The reasons people choose it are practical and personal:

• Looks. A white motor on a white hull just looks right. Many customers say it makes the whole boat look newer.
• Heat. A white cowl stays cooler to the touch in strong sun. You will notice it if you rest your arm on it.
• Resale. On white boats, a matching motor can help when you sell the rig later.
• Scratches. Light scuffs show less on white than on dark paint, though dirt and fuel stains show more.

The only real downside of the Suzuki DF25ATHLW2 for sale is a small price difference over the dark model, and you need to keep it a little cleaner. A wipe down after each trip handles that.

Keeping the white finish clean

Use a mild boat soap and soft cloth. Avoid harsh solvents on the cowl. A coat of marine wax two or three times a season keeps the finish bright and makes salt and grime wipe off. Exhaust soot near the idle relief port and the waterline will build up a little. A bit of soapy water removes it if you do it often.

Which boats suit the Suzuki DF25ATHLW2 for sale

The long 20 inch shaft fits transoms of around 20 inches. In practice the Suzuki DF25ATHLW2 for sale goes on:

• White fibreglass skiffs and small centre console hulls run from the back.
• Large inflatables and RIBs with a 20 inch transom.
• Aluminium boats with white paint or a white liner.
• Yacht tenders that need to match the mother ship.
• Dive and survey tenders where a light colour is preferred.

Always check the capacity plate on the transom. If it says 25 HP or more, you are good. If it says 20, look at the Suzuki DF20ATHLW2, which is the 20 HP version in the same white.

Real world performance

On a light RIB the Suzuki DF25ATHLW2 for sale feels lively, pops onto plane quickly and runs well into the twenties mph with a light load. On a heavier 16 foot skiff with three people, expect it to plane cleanly and cruise in the high teens. Your boat, load and prop decide the real numbers, so treat anything like this as a rough guide.

These figures are Suzuki’s published data for the DF25A range. Weight is dry, without prop and oil, and approximate.

Suzuki’s product family overview for the DF25A and DF30A is on the Global Suzuki DF30A and DF25A page.

What the motor brings to the boat

Fuel injection that does not need a battery

The DF25A’s EFI makes its own electricity from the flywheel once the engine turns. On the Suzuki DF25ATHLW2 for sale you normally start it with the key, but if the battery is flat you can rope start it and it will run. That is a big deal on a tender far from the dock.

Lean Burn fuel savings

Lean Burn Control on the Suzuki DF25ATHLW2 for sale trims the fuel mixture at steady cruise. It is one of the reasons small Suzukis are known for long range on a portable tank. Our customers with older carbureted motors usually notice the difference within the first few trips.

Power trim and tilt

The trim switch lets you set the running angle while under way and tilt the motor fully up when stopped. For a tender pulled up a beach, or a boat left on a mooring with the motor raised, this alone is worth the extra over a manual tilt model. On the Suzuki DF25ATHLW2 for sale the trim unit sits neatly inside the white bracket.

Smooth three cylinder engine

Three cylinders, an offset crankshaft and roller rocker arms keep vibration and noise down. Trolling is smooth and conversations on board do not need shouting.

Protection and convenience

• Three warning LEDs: oil pressure, overheat, over rev.
• Over rev limiter.
• Start in neutral only.
• Freshwater flush port on the motor.
• Easy to reach front shift lever.
• 12V 14A charging for electronics.

Rigging the Suzuki DF25ATHLW2 for sale

A tiller motor like the Suzuki DF25ATHLW2 for sale needs very little extra. For the Suzuki DF25ATHLW2 for sale, plan for:

1. A 12V marine battery, securely strapped in a vented box. It runs the starter and the trim motor.
2. A portable fuel tank, fuel line and primer bulb.
3. Through bolts for the transom bracket. We always advise this on power tilt motors.
4. Engine oil to top up if the crate arrived without it. Check the dipstick before the first start.
5. A suitable propeller for your hull and load.
6. Optional: tiller extension, battery switch, small fuse panel for electronics.

Picking a prop

The rule is simple. At full throttle with a normal load, the Suzuki DF25ATHLW2 for sale should run between 5,000 and 6,000 rpm. If it bounces off the rev limiter, the pitch is too low. If it cannot reach 5,000, the pitch is too high. RIBs and light skiffs often take more pitch than heavy aluminium work boats. Tell us your hull and load and we will point you at a starting prop.

Fitting it to a RIB or yacht tender

A lot of our white motors go onto inflatables, so here is what we have learned rigging them. RIB transoms are often thinner and softer than an aluminium boat’s. Check that your transom is rated for a 25 HP and about 74 kg of motor hanging off it. Most 3.8 to 4.6 metre RIBs with a 20 inch transom are fine, but smaller tenders often are not.

Use a transom plate or large backing washers so the clamp screws do not dig into the wood. Through bolt the bracket. On a tender that gets lifted onto davits, make sure the Suzuki DF25ATHLW2 for sale can tilt fully up without hitting the tubes, the davit arms or the swim platform.

Weight balance

A 25 with power tilt is heavier than a 15 or 20 on the back of a small inflatable. With one person sitting at the tiller, the bow can rise more than you expect. Put the fuel tank and battery as far forward as the lines allow. A boat that sits level gets on plane faster and uses less fuel. Several of our customers moved the battery to the bow locker and gained a few miles per hour.

Davit and deck stowage

If the tender is stored on the yacht’s deck, lay the motor down only on the side shown in the owner’s manual. The wrong side lets oil migrate where it should not. Better still, stow the Suzuki DF25ATHLW2 for sale upright on a motor bracket on the rail.

Getting the tiller comfortable

Spend ten minutes on these adjustments when the motor is new:

• Set the steering friction so the motor holds a line when you let go briefly.
• Set the throttle friction so the grip stays put while trolling.
• Adjust the trim tab on the gearcase so the boat runs straight with no hand pressure.
• Clip the kill cord to your body, never to the boat.

A tiller extension is cheap and useful on tenders where you want to sit on the tube further forward. We can include one with the Suzuki DF25ATHLW2 for sale if you ask when ordering.

Measuring the transom

Before you order the Suzuki DF25ATHLW2 for sale, measure the transom height at the centre, from the top down to the bottom of the hull. About 20 inches suits this motor. About 15 inches calls for the short shaft white model, the Suzuki DF25ATHSW2.

Once mounted, the anti-ventilation plate should line up with the bottom of the hull or sit just below it. On RIBs, measure from the top of the transom to the bottom of the keel line, not to the tubes.

Break-in procedure

A new Suzuki DF25ATHLW2 for sale needs about 10 hours of gentle running before you use it hard. What we tell every customer:

• First 2 hours: mostly at or below half throttle. Short bursts to plane are fine.
• Next hour: up to three quarter throttle, changing speed often.
• Up to 10 hours: full throttle in short spells of a minute or two.
• All along: do not hold one speed for a long time.
• At about 20 hours: first service with oil and filter change.

Check the oil level before every outing during this period. New engines can use a little oil while the rings bed in.

Maintenance on the Suzuki DF25ATHLW2 for sale

The owner’s manual has the official intervals. Here is a practical summary:

For filters, impellers, anodes and touch up paint in the correct white, check Suzuki genuine parts and accessories. We can also put a service kit in the crate with your Suzuki DF25ATHLW2 for sale.

Touch up paint

If you chip the white finish, touch it up quickly, especially in salt water. Bare aluminium corrodes fast. Clean the chip, use the matching Suzuki touch up paint, and let it cure before running.

Salt water routine

Lots of white motors end up on coastal boats, so salt care matters. For the Suzuki DF25ATHLW2 for sale:

• Flush with fresh water through the flush port after every salt trip.
• Rinse the cowl, bracket, trim unit and gearcase.
• Raise the motor out of the water when moored.
• Inspect and replace anodes when they are half worn. Never paint them.
• Spray electrical connectors and the powerhead with a corrosion inhibitor monthly.
• Keep the battery terminals clean and greased.

A white cowl will show salt crust quickly. That is actually useful: if it looks crusty, it is time for a rinse.

Running electronics from the alternator

The Suzuki DF25ATHLW2 for sale charges its battery through a 12V 14A alternator. That is enough for the starter, the trim, a fish finder or small chart plotter, navigation lights and a VHF. It is not enough for big loads like a powerful anchor winch or a big stereo. Wire everything through a fuse block, keep connections out of spray, and use tinned marine wire. Cheap wire corrodes inside the insulation in salt air within a season or two.

If the boat sits for long periods, a solar trickle charger or a maintainer keeps the battery healthy. Dead batteries cause more failed starts than anything mechanical.

Shallow water, beaching and trailers

Power tilt is great for beach landings. Ease in at idle, trim the Suzuki DF25ATHLW2 for sale up as the water gets shallow, watch the telltale, and kill the engine before the skeg touches. Then tilt it fully up before people climb out. Reverse the steps when you leave. Never run in reverse in very shallow water, the prop throws sand and stones into the gearcase seals.

On a trailer, support the lower unit with a transom saver bar rather than leaving all the load on the trim cylinders. Rough roads put big shock loads through the bracket. That small bar saves a lot of money.

Manual release valve

On the bracket there is a manual release valve. Open it and you can move the motor by hand if the battery is flat or the trim motor fails. Shut it again before you run, or the motor will lift when you go into reverse.

Fuel and winter care

The EFI system is much less sensitive than a carburettor, but bad fuel still causes most small motor faults. Keep it simple:

• Buy fresh unleaded and avoid high ethanol blends.
• Add stabiliser to fuel that will sit for more than a few weeks.
• Fit a water separating filter if you buy fuel at small marinas or remote stations.
• Inspect the primer bulb and hose every season.

Before a winter layup, run stabilised fuel through the Suzuki DF25ATHLW2 for sale, flush with fresh water, change engine and gear oil, wax the cowl, and store it upright or tilted down on the boat under a breathable cover. Keep the battery charged. Come spring, it should start on the key straight away.

On fuel use: a 25 HP four stroke at relaxed cruise on a light RIB often uses around 1.5 to 2 gallons (6 to 8 litres) an hour, less trolling and more at full throttle. Every boat is different, so use it as a rough figure for planning.

Common problems and easy fixes

Engine cranks but does not start

Check the tank vent, squeeze the bulb until firm, confirm the fuel connector is clicked home, and check the kill cord. Stale fuel is the next most likely cause.

Trim does not work

Weak battery first, then fuse and connections. Use the manual release valve if you need to lower the motor in the meantime, and close it again before running.

Weak telltale

Clear the hole with a wire, check intakes for weed, then suspect the impeller.

Boat pulls to one side

Adjust the trim tab above the prop a little at a time until the tiller feels neutral at cruise.

Stains on the cowl

Fuel spills and exhaust soot stain white paint. Wipe them as soon as you see them. Use soap and water, not solvent.
