SUZUKI 20 HP DF20ASW2 OUTBOARD MOTOR

Description

We are selling the Suzuki DF20ASW2 for sale new, in the factory carton. It is the white version of Suzuki’s 20 HP four stroke tiller engine, with pull-cord start, a 15 inch short shaft and manual tilt. The price is on the page, and we deliver worldwide.

The W in the code gives you a white cowl. Mechanically it is the same engine as the black DF20AS2, so you are choosing colour and nothing else. For yacht tenders, white workboats, and anyone who dislikes how black plastic heats up in strong sun, white is the sensible pick.

Everything you need to decide is here: the specifications, why white is more than a looks choice, which boats fit, and how to set up and care for the engine. Delivery is quoted before you pay.

Final figures are in the paperwork that comes with the engine. For a side by side look at other small models, visit Suzuki’s 2.5 to 30 HP outboard range.

Why White Matters on the Suzuki DF20ASW2 for sale

A white cowl reflects sunlight, so it stays cooler than a black one when the boat sits in the sun at a mooring or on a trailer. That is a small thing, but if you lift the cowl to check oil on a hot day, you notice it.

It also matches white boats. Fibreglass dinghies, RIB tenders and aluminium boats with white paint look better with a white engine, and plenty of yacht owners care about this. Finally, white hides salt crust and sun fade better than black does, though it shows oil and grease marks sooner. A damp cloth after each trip keeps it clean.

Under the cowl of the Suzuki DF20ASW2 for sale there is no difference. Same block, same injection, same warranty paperwork as the black version.

Reading the Suzuki DF20ASW2 for sale Model Code

DF is Suzuki four stroke and 20 is the horsepower. A is the generation. S is the 15 inch short shaft. W is the white cowl. The final 2 is the production series.

There is no E, so no electric start, and no T, so no power tilt. If you want the button, look at the Suzuki DF20AES2. For the same engine in black, there is the Suzuki DF20AS2.

Where the Suzuki DF20ASW2 for sale Fits in the Range

Suzuki sells the 20 HP block in about a dozen forms. Pull start or electric start. Short shaft or long. Manual tilt or power tilt. Black or white. Some versions even come with remote steering. That sounds confusing, but the choice is simple once you know your boat.

The Suzuki DF20ASW2 for sale is the simplest version in white. It is the one to pick if you have a short transom, a boat you carry or hang from davits, and no need for a battery. If you have a bigger or heavier boat, step up to a long shaft or a power tilt model such as the Suzuki DF20ATHLW2.

Boats That Suit the Suzuki DF20ASW2 for sale

Yacht tenders and RIBs

A white tender with a white engine looks neat on the foredeck or the davits. The light weight makes it practical to hoist.

Aluminium fishing boats

Many are painted white or left bare. A 14 to 16 foot boat with a short transom is the standard match.

Inflatable boats

Soft-bottom and RIB inflatables with a short transom take this engine without problems. Look at the plate for limits.

Dive and survey boats

Small working boats that carry a few people and equipment benefit from a simple engine with no battery to fail.

Small cabin cruisers

On a well-mounted bracket, it moves a small sailing cruiser through a harbour without the weight of a larger engine.

Handling the Suzuki DF20ASW2 for sale

The twist grip throttle has a tension screw. The gear lever sits on the front of the cowl, so you can reach it while holding the tiller. A friction control lets you set the steering feel. A lanyard stop switch is at hand, and the start-in-gear lockout stops the engine from cranking unless the lever is in neutral.

Pull start on the Suzuki DF20ASW2 for sale is simple. Neutral, lanyard clipped, a firm pull along the line of the cord. If the fuel line has been off, squeeze the primer bulb first. The fuel injection works without a battery, so a few pulls usually bring it to life.

On the Water

The Suzuki DF20ASW2 for sale idles evenly and quietly, and the exhaust goes out through the prop hub. In a light boat, it comes onto the plane without fuss. A heavy hull needs a lower pitch or a high thrust propeller.

We do not quote speeds or fuel use because they depend on your boat and load. What we can say is that the full throttle range is 5,000 to 6,000 rpm, and that the Suzuki DF20ASW2 for sale is tuned for smoothness and economy rather than noise.

Setting Up the Suzuki DF20ASW2 for sale

Make sure the transom is sound before fitting the Suzuki DF20ASW2 for sale, and measure its height. For a 15 inch shaft, it should be close to 15 inches. Clamp the engine, tighten the screws evenly and fit a safety chain.

Set the anti-ventilation plate level with the bottom of the hull. Run the boat and look at the wake. Raise or lower the engine until the boat trims level and the prop holds in turns. Adjust the tilt pin for the bow angle you want.

Propeller Choice

The correct propeller lets the engine reach 5,000 to 6,000 rpm at full throttle with your usual load. If it cannot, lower the pitch. If it goes beyond the range, raise it. A high thrust propeller helps heavy boats. Suzuki’s genuine parts and accessories include propellers for the whole range, and we can suggest a size for your boat.

Break-In

Follow the break-in section of the manual. Keep revs varied for the first hours and avoid long runs at full throttle. Change the engine oil and gear oil at the first service. Good break-in habits keep the engine easy to start and cheap to run.

Servicing the Suzuki DF20ASW2 for sale

• Flush after use in salt, brackish or dirty water.
• Change engine oil and filter on schedule, or once a year.
• Change gear oil each season.
• Replace the impeller every two to three seasons.
• Replace anodes at half wear.
• Check the cord and the recoil starter.
• Use fresh fuel and replace the filter.
• Check plugs and valve clearance at the manual’s intervals.

The Suzuki DF20ASW2 for sale is a straightforward engine, and a home mechanic with basic tools can handle it. Keep a record of each service.

Keeping a White Cowl Clean

Wipe the cowl with a damp cloth and mild soap after each salt trip. Avoid abrasive pads that scratch the finish. Once or twice a year, apply a marine polish or wax to protect the paint and make cleaning easier. Do not use solvents on decals or plastic parts.

Touch up chips quickly with the matching paint from a Suzuki dealer. Bare plastic or metal under a chip starts corroding fast in salt water.

Salt Water, Storage and Cold Weather

The Suzuki DF20ASW2 for sale is rated for salt water and has a multi-layer finish. Flush it every time. Store it upright and drained. For long storage, stabilise the fuel, change the oil and cover the engine. In cold climates, drain the cooling water before frost.

Suzuki DF20ASW2 for sale Against the Black DF20AS2

Some buyers ask us whether the white engine costs more, whether it is made differently and whether it is worth waiting for. The white engine here is priced a little above the black one. The extra is for the paint and cowl, not for any mechanical change. If the colour does not matter to you, buy the cheaper black one and put the difference towards a spare propeller.

If colour does matter, and it often does on a yacht tender, the Suzuki DF20ASW2 for sale is the engine to order. Stock of white engines can be tighter than black, so ask us about availability before you commit to a delivery date.

A Tender Owner’s Notes on the Suzuki DF20ASW2 for sale

Tender engines live hard lives. They get lifted over rails, banged against hulls, left in the sun and soaked in spray. Pull start suits that life because there is nothing electrical to drown. Keep the fuel tank on the tender and carry a spare cord.

Rinse the engine with fresh water whenever you can, particularly after a day in a harbour with muddy water. Store it upright on the stern rail if it hangs there, with the lanyard looped so it cannot swing. Take the tank off if the tender is stored on deck, and keep fuel out of the sun.

Lock the engine to the tender. A white engine on a white tender is easy to spot at a dock, and thieves know the value of a clean 20 HP.

Lifting and Carrying the Suzuki DF20ASW2 for sale

At 97 lb you will want a plan. Carry it upright, using the built-in handle, with a second person on the other side if there are steps. If you hang it on a stern bracket, a small hoist with a strap saves backs.

Do not lift by the cowl latch or the tiller. Do not lay the engine down on a hard surface without a pad, or you will chew the finish. A scrap of carpet or a folded towel protects the white paint.

Fuel Quality and Filters

Use fresh unleaded fuel of the grade in the manual, and avoid fuel that has sat for months. Ethanol blends stale quickly in small tanks. A fuel filter with a water trap is cheap and worth fitting if the quality of fuel where you boat is poor.

Trailer, Davit and Bracket Use of the Suzuki DF20ASW2 for sale

How you store and move the engine affects its life more than most owners think. On a trailer, tilt the leg fully up, engage the tilt lock lever and, if the road is rough, add a transom saver. On davits, keep the engine off the tender and carry it separately, or lash it so it cannot swing. On a stern bracket, check the bracket bolts every season, since vibration loosens them over time.

Avoid leaving the engine tilted at a low angle with the cowl pointing down. Water can collect in places it should not. Keep the Suzuki DF20ASW2 for sale upright in storage, and tilted up only with the lock engaged.

How Many People Can It Push?

There is no honest single answer. It depends on the hull and its weight, the load, the prop and the water. A small aluminium boat with two adults is easy. Five adults in a short tender will go slowly and may not plane at all. The best test is to load the boat as you normally would, fit the correct propeller and see where the revs land. If the engine reaches 5,000 rpm or more at full throttle, it is working correctly.

If the boat will not plane, check the weight distribution first. Move people and gear forward, trim the leg in, and try again. A change of propeller is the next step. Talk to us about the boat and we can suggest a prop before you buy.

Understanding the Safety Systems

The engine has a low oil pressure warning, an overheat warning and an over-rev limiter. If an alarm sounds, back off at once and find the cause. Do not keep running with an alarm. A few seconds of ignoring it can turn a minor fault into a major repair.

The lanyard stop switch is the most important safety device on any tiller boat. Clip it to your clothing every time you start. A small boat can turn sharply if the driver falls, and the lanyard kills the engine before the propeller can do damage.

Fitting Accessories to the Suzuki DF20ASW2 for sale

A few accessories are worth considering. A tiller extension lets you sit further forward and shift your weight, which helps in a small boat. A fuel tank gauge saves guesswork. A flush kit with a hose adapter makes washing out the cooling system easy. A cowl cover protects the white paint during storage.

Choose accessories from reputable makers and make sure they are designed for this engine. Poorly made parts can cost more than they save.

Talking to Us Before You Buy the Suzuki DF20ASW2 for sale

If you are unsure about any point, send us a message. Tell us your boat make and length, the transom height, the maximum power on the plate and the country you are in. We will tell you whether this engine fits, whether another version suits you better, and what the delivery will cost. There is no charge for the advice, and we would rather answer ten questions than sell the wrong engine.

Plug, Oil and Filter Notes

Use the spark plug type and gap given in the owner’s manual, and never guess. Check the plugs at the first service, then every season. A tan or light grey insulator means the engine is running well. Black soot suggests too much idling or a rich mixture. White or blistered tips mean a lean mixture or overheating, and that needs a proper check.

For oil, use the grade the manual lists and fill to the mark on the dipstick, not above it. Overfilling a small sump with only about a litre of oil causes frothing and can push oil into places it should not go. Replace the oil filter at each oil change and wipe the sealing ring with a drop of fresh oil before fitting.

Common Problems and Quick Checks

Will not start. Check the lanyard, neutral, tank vent and fuel line.

Starts and stalls. Dirty fuel or a blocked vent. Open the vent and change the filter.

Weak tell-tale. Clear the outlet and inspect the impeller.

Will not reach full revs. Prop too big or boat overloaded.

Alarm sounds. Slow down and check cooling and oil.
