The people who buy this white short shaft

We sell the Suzuki DF25ATSW2 for sale mostly to three groups.

RIB and inflatable owners

Many rigid inflatables in the 13 to 15 foot range have a small centre console and a short shaft transom. White matches the hull and the tubes, and a remote setup means the driver stands at the console, keeping the bow down. A 25 HP is a common rating for these boats.

Yacht tender owners

Larger yachts often carry a console tender. Those tenders get used hard, launched and lifted often, and need to start every time. EFI and electric start suit that work. The white finish matches the yacht. Several of our Suzuki DF25ATSW2 for sale orders each year go to tender use.

Small coastal skiffs

Low transom fibreglass skiffs with a side console, used for fishing in bays and harbours. White hull, white motor. The power trim lets them run shallow over sand and grass.

Who should pick something else

If your transom is about 20 inches, the Suzuki DF25ATSW2 for sale is too short. The prop will sit too high and blow out. Look at the DF25ATLW2. If you want a tiller, look at the DF25ATHSW2. If you do not care about colour, the dark DF25ATS2 is the same motor.

What DF25ATSW2 stands for

Here is the model code on the Suzuki DF25ATSW2 for sale, read one piece at a time:

No H means no tiller. This is a remote steer motor. Electric start is standard on the remote power trim models, so there is no E in the code.

Inside the Suzuki DF25ATSW2 for sale

Battery-less EFI

Suzuki made the DF25A the first 25 HP outboard with fuel injection that runs without a battery feeding it. Once the motor turns, it powers its own injection. The Suzuki DF25ATSW2 for sale needs its battery to start and to trim, but a sagging battery will not upset the fuel injection once the engine is running.

For a tender or a RIB that sits for days between uses, that is the feature that matters. No choke, no flooding, no carb gumming up. It starts.

Lean burn

The ECU reads load and leans the mixture when it can. At cruise, which is where most running happens, fuel use drops. Owners moving to the Suzuki DF25ATSW2 for sale from a carb four stroke or a two stroke usually notice they fill up far less often.

Three cylinders

Most 25s in the past were twins. Three cylinders run smoother, especially at idle and low speed. On a RIB where the motor sits close to the passengers, less vibration and less noise make a real difference.

Power trim and tilt

Trim is on the remote handle. RIBs and light skiffs respond a lot to trim. Trim in to get on plane fast with a load. Trim out to lift the bow in a chop. Tilt up for beaching, the trailer, or davits. There is a shallow water position for slow running with the leg partly raised.

Protection

• Low oil pressure warning
• Over-rev limiter
• Freshwater flush port
• Suzuki anti-corrosion system
• Through hub exhaust for quiet running

Keeping the white finish white

The white is paint and gelcoat style finish over the same parts as the dark motor. It looks great on a white boat, but it needs a little care to stay that way.

• Rinse the motor after every trip, including the leg, to stop salt crust and exhaust stains setting in.
• Use a mild boat soap, not harsh cleaners or scouring pads.
• Wax the cowl two or three times a season with a marine wax.
• Touch up chips on the leg early with Suzuki touch up paint so corrosion cannot start.
• Use a cowl cover if the boat lives in strong sun.

Do that and the Suzuki DF25ATSW2 for sale will still look new years from now. Do nothing and it will look grubby by the end of the first summer.

Rigging a RIB or tender with the Suzuki DF25ATSW2 for sale

Most of our white short shaft remote motors go onto RIBs and tenders, so here is how that rig usually comes together.

Parts list

On many RIBs the console is close to the transom, so cables and harness are short. Measure anyway. Genuine Suzuki controls and gauges can be found on the Suzuki genuine accessories pages, and we can quote a set with the Suzuki DF25ATSW2 for sale.

Mounting on an inflatable transom

Inflatable and RIB transoms are often plywood with a fabric or fibreglass cover. Through bolt the motor with stainless bolts and wide backing plates to spread the load. Seal every hole. Check the motor height: the anti-ventilation plate should sit level with the bottom of the hull at the keel, or a little above.

Tender specifics

If the tender is lifted on davits or a crane, keep the battery strapped hard and the fuel tank secured. Tilt the motor up before lifting. Flush it with fresh water from the yacht’s supply whenever you can.

Propeller

The listing shows a 3 blade 10.25 x 11 aluminium prop. RIBs with a load often run better with a little less pitch. Test with a typical load and read the tach at full throttle. Aim for 5,000 to 6,000 rpm. We can help pick a better prop for the Suzuki DF25ATSW2 for sale if needed.

Installation order we follow

1. Check and repair the transom if needed.
2. Hang the motor on the centre line and set the height.
3. Drill and through bolt with sealant in every hole.
4. Fit the control on the console at a comfortable hand height.
5. Run the throttle and shift cables and the harness with gentle bends, tied so they cannot chafe on the tubes or deck.
6. Install the helm, steering cable and link arm, and grease the ram.
7. Strap the battery in its box near the console or transom with short, heavy cables.
8. Connect the fuel line and filter, then squeeze the bulb firm.
9. Adjust the cables so the throttle opens fully and the shift engages cleanly in forward, neutral and reverse.
10. Confirm the motor will not crank in gear, then test on muffs and on the water.

A handy owner can rig the Suzuki DF25ATSW2 for sale in a day. If you would rather not, any marine mechanic can do it. Give them the parts list above so nothing is missing when they start. We are glad to answer rigging questions on the phone too, before or after the Suzuki DF25ATSW2 for sale arrives.

Is your transom really 15 inches?

1. Measure at the centre of the transom.
2. Run the tape from the top of the transom down to the bottom of the hull, following the transom’s slope.
3. About 15 inches: the Suzuki DF25ATSW2 for sale fits.
4. About 20 inches: you need the long shaft DF25ATLW2.

On RIBs, measure to the bottom of the hull, not the bottom of the tubes. If you are not sure, send us a photo with the tape in view and we will check it.

Break-in, the first ten hours

Follow the owner’s manual for the exact procedure. The usual pattern for a new Suzuki DF25ATSW2 for sale:

• First 2 hours: low speeds, under half throttle, vary the rpm often.
• Hour 3: up to three quarter throttle.
• Hours 4 to 10: short full throttle runs, then back off. Keep changing speed.

Then the first service: engine oil and filter, gear oil, and checks on cables, steering and fasteners.

Maintenance plan

Tenders often run lots of short trips, idling and low speed. Watch oil condition more closely on a tender and do not stretch the oil changes on the Suzuki DF25ATSW2 for sale.

Coastal and salt water care

The Suzuki DF25ATSW2 for sale is salt water rated, and most of them spend their lives on the coast. Suzuki’s anti-corrosion system protects the aluminium. Your job is to keep salt off it.

• Fresh water flush through the flush port after each salt day.
• Rinse the outside, the trim rams, the steering ram and the clamp brackets.
• Keep the leg tilted out of the water when moored.
• Replace anodes at about half worn. Do not paint them.
• Grease the swivel and tilt points every month or two.
• Spray corrosion guard inside the cowl a few times a year.

Common problems and quick fixes

No crank

Control lever not in neutral, battery low, or a corroded terminal. Check in that order.

Starts then stalls

Tank vent closed or a kinked fuel line. On tenders, a fuel line pinched under a seat is common.

Trim will not work

Low battery first. Then check the trim switch plug and the trim fluid level.

Overheat alarm

Plastic bags and weed on the intake are the usual cause near harbours. Clear it. If the stream stays weak, replace the impeller.

Repowering with the Suzuki DF25ATSW2 for sale

Plenty of our white short shaft remote orders replace an older motor on a RIB or skiff that is still in good shape. Before the old motor comes off, run through these checks.

Transom and tubes

On a RIB, look at where the transom meets the tubes and the hull. Any lifting fabric, cracks or soft wood need repair first. Press hard on the top of the transom with the old motor tilted down. If it moves, fix it. The Suzuki DF25ATSW2 for sale is light, but a weak transom gets worse under any motor.

Bolt pattern

Old holes rarely line up with a new motor from another brand. Fill the old ones with thickened epoxy and drill fresh. Use stainless through bolts with large washers or a backing plate.

Controls and harness

Controls and harnesses from another brand will not connect to the Suzuki DF25ATSW2 for sale. Budget for a Suzuki control and harness. A steering cable that moves freely and is the right length can usually stay.

Fuel

Replace old hoses, the primer bulb and any old filter. Empty and clean the tank or replace it. EFI motors do not like dirt or water, and old fuel systems carry both.

What owners tell us after the first season

We hear back from a fair number of buyers. The comments on the Suzuki DF25ATSW2 for sale are pretty consistent.

Starting comes up first. Tender owners especially like that it fires on the key after sitting for a week on davits. Quiet running is next. On a RIB you sit right next to the motor, and owners coming from two strokes notice the difference straight away.

Fuel use is the third. Most say they buy far less fuel than before. The main complaint is the prop. RIBs with a regular load of passengers often need less pitch than the listed prop. That is a quick, cheap fix, and we help with it.

A few owners mention the white shows exhaust soot at the back of the cowl and on the leg. A rinse and a wipe after each trip keeps the Suzuki DF25ATSW2 for sale clean.

Trailers, davits and storage

On a trailer, support the motor with a transom saver or the tilt support. Bumpy roads with the weight on the trim rams wear them. On RIB trailers, check the skeg clears the road and any trailer cross member when tilted.

On davits, tilt fully up before lifting and make sure nothing in the boat can slide into the motor. Drain or secure the fuel tank as your yacht’s routine requires.

For a winter layup, stabilise the fuel and run the Suzuki DF25ATSW2 for sale so treated fuel reaches the injectors. Change the oil, grease the fittings, charge the battery and keep it on a maintainer. Store the motor upright or as the manual shows, under a breathable cover.

In spring, check the cowl for nests, charge the battery, squeeze the bulb, and start it on muffs. Watch the tell-tale.

Fresh water use

Lake and river owners should still flush the Suzuki DF25ATSW2 for sale after muddy or sandy trips. Silt in the cooling passages causes overheating just like salt does, only slower.

Running costs

Fuel is the biggest cost. A RIB or skiff with the Suzuki DF25ATSW2 for sale uses a few litres an hour at a relaxed cruise, more at full throttle, and very little at idle. A 6 gallon tank usually covers a full day.

Service parts are cheap and easy to find through Suzuki dealers worldwide. Keep spare plugs, an impeller, a fuel filter and a kill cord clip aboard. Tender crews often keep a spare prop too.
