Suzuki 20 HP DF20ATSW5 Outboard Motor

Description

Here is a new Suzuki DF20ATSW5 for sale: a white 20 HP fuel injected outboard set up for remote steering, with a 15 inch short shaft, electric start and power tilt. It is new in the Suzuki crate, the price is on this page, and we ship it worldwide after sending you a delivery quote.

This is the motor for small console boats with a short transom. Think rigid inflatables with a centre console, small runabouts and little side console skiffs. You drive from a wheel and a control lever, and the white cowl suits the light coloured hulls these boats usually have.

Reading the Suzuki DF20ATSW5 for sale model code

We always go through the code with buyers, because one wrong letter means the wrong motor arrives. The Suzuki DF20ATSW5 for sale breaks down like this.

• DF is Suzuki’s four stroke line.
• 20 is the power, 20 HP or 14.7 kW.
• A is the current small block, a 327 cc injected twin.
• T is power tilt.
• S is the short shaft, 15 inches, for a transom of about 381 mm.
• W is the white cowling.
• 5 is the production series.

Note what is missing. There is no H, so there is no tiller handle. The Suzuki DF20ATSW5 for sale is steered and controlled from the helm through cables. If you want the same short shaft in a tiller, look at a tiller model instead. If you want this layout in the standard colour, the Suzuki DF20ATS5 is the same motor without the W.

Suzuki DF20ATSW5 for sale: specifications

Suzuki’s own sheet for the 20, 15 and 9.9 twins is on the Global Suzuki portable outboard page. Weight changes slightly with the remote and tilt hardware, so go by the label that ships with the Suzuki DF20ATSW5 for sale.

Boats the Suzuki DF20ATSW5 for sale is made for

A 15 inch transom and a steering console is a fairly specific combination. That is exactly why the Suzuki DF20ATSW5 for sale exists. Here are the boats we ship it for most.

Rigid inflatables with a centre console

This is the big one for the Suzuki DF20ATSW5 for sale. Many RIBs in the 3.5 to 4.5 metre range have a 15 inch transom and a small console with a wheel. A 20 HP remote motor turns them into a quick, dry little boat for diving, fishing and running out to a mooring. Check the RIB’s plate for the maximum HP and weight before you order.

Small runabouts and side console boats

Older 12 to 14 foot fibreglass runabouts often have a short transom and a side console. Many came from the factory with a 20 or 25 HP two stroke. The Suzuki DF20ATSW5 for sale is a common replacement because it is lighter than many older motors and far quieter.

Yacht tenders with steering

Larger tenders with a console need a short shaft remote motor. The white cowl matches most yacht colour schemes. Power tilt is handy when the tender is lifted onto a swim platform or davits.

Small work boats

Harbour skiffs and marina workboats with a short transom and a helm seat also use this setup. The operator stays seated at the console all day rather than twisting round to a tiller.

Why white, and why remote

White matters to people with white boats, and that is who buys the Suzuki DF20ATSW5 for sale. RIB tubes are often grey or white, consoles are white, and a black motor stands out. With the Suzuki DF20ATSW5 for sale, the whole boat looks like one package. White also shows stains early, so leaks and soot get noticed.

Remote steering matters more. You sit or stand at the console, look forward, and have both hands free when you need them. Passengers sit where they balance the boat best, not wherever the tiller handle allows. On a RIB that changes how the boat rides in a chop.

The cost is rigging. You need a steering system, a control box and cables. We cover that in detail below so there are no surprises when the Suzuki DF20ATSW5 for sale arrives.

What the Suzuki DF20ATSW5 for sale is like to drive

Turn the key at the control box and the twin starts almost at once. Idle is smooth and steady, cold or warm, because the injection meters fuel properly from the first turn. On a RIB you can hear the water slapping the tubes over the engine at idle.

Push the lever into forward and the Suzuki DF20ATSW5 for sale engages with a soft click. Roll on throttle and a light RIB with two people climbs onto the plane quickly. Keep weight forward of the console on the first runs while you learn how the boat sits.

At cruise around 4,000 to 4,500 rpm the motor is relaxed and quiet. The wheel stays light with mechanical steering on a 20 HP. If it feels heavy, that is usually a dry steering cable, not the motor. Slow speed handling is easy with the remote lever, which makes docking a tender at a busy marina much less stressful.

Features of the Suzuki DF20ATSW5 for sale

Battery-less EFI

Suzuki’s injection does not rely on the battery to run. Once the engine turns, it makes its own power for the injectors. If the battery fails, you can take the cover off and start with the recoil cord, then motor home. It also means no carburettor to gum up when the boat sits.

Lean Burn Control

At steady speeds the ECU leans the mixture. You will not notice it at the helm, but you will notice it in fuel bills over a season with the Suzuki DF20ATSW5 for sale.

Power tilt

The tilt switch is on the lower cowl, and many control boxes have a tilt switch in the handle as well, depending on the control you choose. You can raise the leg for beaching, shallow water, trailering or clearing weed without reaching over the transom.

Protection and warnings

Low oil pressure warning, overheat warning, over rev limiter and start in gear protection. With a remote setup, the warning signals reach you through the control or the gauge, depending on how it is wired. Read the rigging manual so you know what each signal means.

Quiet running

Through hub exhaust and the four stroke design keep the Suzuki DF20ATSW5 for sale quiet. On a RIB with no hull insulation, that makes a real difference over a day out.

Rigging the Suzuki DF20ATSW5 for sale: the full parts list

A remote motor needs more parts than a tiller. Here is what most boats need. Some may already be on your boat if you are replacing a remote motor.

• Remote control box: a Suzuki side mount or top mount control with the key switch and lanyard. It must match the motor.
• Throttle and shift cables: two cables, measured from the control to the motor along the route they will take.
• Steering system: mechanical cable steering with a helm and a steering cable, plus a link arm to the motor.
• Wiring harness: the main harness from the control box to the engine. Length must cover the run.
• Battery: a 12 V marine starting battery in a vented box, with correct size leads.
• Fuel system: a portable tank or a fixed tank, fuel line with primer bulb and a water separating filter if the tank is fixed.
• Optional gauges: a tachometer or a simple warning panel helps on a remote boat.

Suzuki’s genuine parts and accessories catalogue lists controls, harnesses and cables. We can quote a rigging kit together with the Suzuki DF20ATSW5 for sale, which saves shipping a second parcel.

Measuring cable length

Run a string or a garden hose from the control box, along the path the cables will take, to the centre of the motor at the transom. Add slack for the motor to turn lock to lock and tilt fully up. Then round up to the next available cable length. Cables that are too short bind. Cables that are far too long loop and kink.

Steering setup

Mechanical steering on the Suzuki DF20ATSW5 for sale is simple and reliable. Measure the steering cable the same way. Grease the cable end where it slides through the tilt tube, and keep it greased every season. A stiff steering cable is the most common complaint on small remote boats, and it is almost always lack of grease or salt build up.

Choosing a battery

A standard marine cranking battery is plenty for the Suzuki DF20ATSW5 for sale. Mount it close to the stern to keep leads short, in a strapped box so it cannot move in waves.

Prop and trim on a RIB or small runabout

The stock aluminium prop is chosen for an average load. Run your boat loaded the way you normally use it, at full throttle on flat water, and read the rpm on a tachometer. The Suzuki DF20ATSW5 for sale wants to land between 5,300 and 6,300 rpm.

• Below the range: reduce pitch an inch or two.
• Above the range: add pitch.
• Inside the range: you are set.

Trim on this motor is set with the pin. RIBs usually like the pin in the middle or one hole in. If the bow rides high and the boat porpoises, move the pin in. If the bow ploughs and spray comes over the tubes, move it out. Change one hole at a time and test.

Fuel planning

A 20 HP injected twin is light on fuel. At cruise, the Suzuki DF20ATSW5 for sale typically burns around a gallon an hour, give or take, depending on boat and load. Many RIB owners run a single portable tank under the console seat. Fixed tanks need a water separating filter between tank and motor.

Use fresh fuel, keep the tank vent open while running, and add stabiliser if fuel will sit more than a few weeks.

Shaft length: confirm the 15 inch transom

Before ordering the Suzuki DF20ATSW5 for sale, measure your transom height at the centre line. Start at the top edge where the bracket sits and go straight down to the bottom of the hull. On a RIB, measure to the bottom of the keel where it meets the transom.

• About 15 inches: short shaft, the Suzuki DF20ATSW5 for sale fits.
• About 20 inches: you need the long shaft version.
• Somewhere between: ask us before ordering.

A long shaft on a 15 inch transom drags the gearcase deep and slows the boat. A short shaft on a 20 inch transom lets the prop suck air and the water intake can starve. Get this right and the anti cavitation plate runs level with the hull bottom.

Breaking in the Suzuki DF20ATSW5 for sale

Suzuki’s manual sets a 10 hour break in. Follow your manual first. The general pattern is:

1. First 2 hours: below half throttle, vary speed, avoid long idling.
2. Next hour: up to about three quarter throttle, short higher runs fine.
3. To 10 hours: normal running, but no long stretches at full throttle.

On a remote boat it is easy to leave the lever in one place for a long time. Do not. Move the throttle up and down regularly during break in. Check oil before each trip, and book the first service at about 20 hours.

Service schedule for the Suzuki DF20ATSW5 for sale

Use SAE 10W-40 four stroke marine oil and hypoid 90 gear oil. On a remote boat, add the control cables and steering cable to the yearly list. Check the throttle and shift adjust at the engine end so the Suzuki DF20ATSW5 for sale shifts cleanly.

Salt water routine for the Suzuki DF20ATSW5 for sale

The DF20A is salt rated and has a flush port. After every salt trip, connect a hose and flush for about five minutes with the motor stopped. Rinse the outside, bracket, tilt tube and steering cable end. Spray corrosion guard on bare metal.

Watch the anodes on the Suzuki DF20ATSW5 for sale. Replace them when half worn, and never paint them. On a RIB kept in the water, tilt the Suzuki DF20ATSW5 for sale fully up. On the white cowl, a mild boat soap and a soft sponge are all you need.

Storing it for the off season

If you lay the boat up, treat the fuel with stabiliser and run the Suzuki DF20ATSW5 for sale for ten minutes so treated fuel fills the system. Flush with fresh water. Change the engine oil and gear oil, check the old gear oil for water, and grease every fitting.

Lubricate the control cables and steering cable while you are at it. Disconnect the battery and keep it on a maintainer at home. Store the boat or the motor where it stays dry, with a cover over the white cowl. In spring, use fresh fuel and test run on a flush muff before launch day.

Common problems and simple fixes

Most of these are five minute fixes. If not, call us or a Suzuki dealer before taking anything apart on the Suzuki DF20ATSW5 for sale, so the warranty stays valid.

• DF25ATSW5: white short shaft remote 25 HP for heavier RIBs.
• DF9.9BTS5: short shaft remote 9.9 HP where power limits are low.

On a RIB or small console boat rated for 20 HP, the Suzuki DF20ATSW5 for sale is a strong match. Heavy boats with lots of gear may want the 25. See every twenty on the 20 HP Suzuki page, or the full Suzuki outboard range.

New motor or a used one?

Used remote twenties come with unknowns. How was it flushed? Did it sit with old fuel? Are the cables and harness corroded? On a remote motor there are more parts to go wrong, and you only find out once it is rigged.

A new Suzuki DF20ATSW5 for sale has zero hours, a factory warranty for your region and clean paint. Pair it with new cables and a matching control box and the whole system starts fresh. Over a few seasons that is usually cheaper than chasing faults on an old setup.
