Suzuki 6 HP DF6AS5 Outboard Motor

Description

The Suzuki DF6AS5 for sale on this page is a new 6 horsepower four stroke outboard with a 15 inch short shaft. It has a tiller handle, a pull cord and a black cowl, and it weighs about 52 lb. It comes in the factory box, the price is shown here, and we ship it worldwide.

Short shaft sixes are the motors people keep for fifteen years. They hang on the back of a dinghy, a little aluminium boat or a camp skiff, and mostly they just work. This page is about getting the best out of one: what to expect, how to set it up, and how to keep it running. The Suzuki DF6AS5 for sale rewards the owner who does the small jobs on time.

You will also find the specs, the model code, delivery details and a set of questions with plain answers. Use the contact page if something is missing and we will answer you directly.

Living With the Suzuki DF6AS5 for sale: A Year of Ownership

Spring. Take the motor out, change the engine oil, look at the spark plug, check the gear oil and look at the prop for nicks. Fit fresh fuel in a clean tank. Clip it on the boat, start it on the muffs or in the water and check the tell-tale stream.

Summer. Use it. After each trip, rinse it if you were in salt or silt. Keep the fuel fresh and the tank vent clear. Look at the clamp screws for tightness, because vibration loosens them.

Autumn. Run the carburetor dry before storage, or add stabiliser. Change the gear oil, and look at it as it drains. Replace the impeller if it is due. Wash and dry the motor and put it away off the floor.

Winter. Leave it alone, covered, in a dry place. If you can, turn the pull cord over slowly a few times to lubricate the cylinder. That is the whole year, and most of it takes minutes.

Suzuki DF6AS5 for sale: Specifications

Figures can differ slightly between production runs, so the documents in the box are final. For the complete list of small Suzuki motors, see Suzuki’s 2.5 to 30 HP outboard page.

How to Read DF6AS5

DF stands for Suzuki four stroke. 6 is the horsepower. A is the small motor generation. S is the short, 15 inch shaft. The 5 marks a later production series than the DF6AS2. No W, so the cowl is black. No E, so it is pull start.

Everyday Habits That Keep the Suzuki DF6AS5 for sale Running

Use fresh fuel

This is the first rule and the most broken. Gasoline goes stale within weeks in a warm tank and leaves varnish in the carburetor. Buy small quantities, keep them in a clean sealed can, and burn them within a month or two.

Run it dry for storage

Close the fuel tap and let the motor run until it stalls. The bowl empties, and the jets stay clean. This takes a minute and prevents most spring problems.

Flush it

Even in fresh water, silt builds up in the cooling passages. A quick flush after each outing keeps the impeller and the passages clear.

Do not lay it down carelessly

Follow the storage positions marked on the motor. Wrong position can let oil run into the cylinder and make the next start difficult.

Boats the Suzuki DF6AS5 for sale Suits

The 15 inch shaft is for transoms of roughly that height. That covers most inflatables, light RIBs, small aluminium boats and many rigid dinghies. A 6 HP motor is well matched to a boat of about 10 to 13 feet carrying a couple of people and a bit of gear.

It is also a favourite for camping and expedition boats: a small boat on a trailer that gets launched at remote ramps. The motor is easy to lift and carry, and there is no battery to charge. Pull it, and go.

If your transom is taller, about 20 inches, you want the long shaft Suzuki DF6AL5 or the earlier DF6AL2.

Starting Routine for the Suzuki DF6AS5 for sale

Cold start: fuel tap open, tank vent open, choke on, throttle slightly open. Pull the cord with a smooth full stroke, not a jerk. When it fires, ease the choke in as the motor warms. Warm start: usually no choke needed.

If it fails to start after ten pulls, stop. Check the lanyard, the fuel, the plug. Flooding a four stroke with repeated pulls and choke makes it worse. Open the throttle fully, remove the choke and pull a few times to clear.

The Controls and What They Do

The twist-grip throttle is on the tiller. Behind it sits the tension adjuster. The side lever selects forward, neutral and reverse. There is a steering friction control so the handle stays where you put it. The tiller folds up for storage and down for use.

Under the cowl there is little to see. The Suzuki DF6AS5 for sale is a simple water cooled carburetted engine with a digital ignition. There are no sensors, no ECU and no wiring harness to chase. That is the main reason owners trust it.

Rigging Notes

Fit the motor to the centre of the transom with both clamp screws tight. Tie a safety line. For an inflatable, check the transom boards are strong enough and that the screws are not resting on a soft panel. Set the height so the cavitation plate is level with the hull bottom. Use the tilt pin to leave the shaft near vertical.

If the prop ventilates in turns, lower the motor a notch. If it drags spray and the speed is poor, raise it a notch. Make small changes and test again.

Fuel Supply

The built-in tank holds roughly a quarter gallon and Suzuki quotes about 45 minutes at full throttle. For longer trips, connect an external tank to the standard fitting on the Suzuki DF6AS5 for sale. Fuel tank and line are separate items and we can quote them with the motor if you want.

Propeller Choice

The standard 3-blade aluminium prop suits most boats. Heavier boats need less pitch to reach 4,750 to 5,750 rpm. Lighter ones can use more. Test at full throttle with your normal load and adjust. Props, plugs and filters are listed in Suzuki’s genuine parts and accessories range.

Breaking In the Suzuki DF6AS5 for sale

Use moderate, varied throttle for the first hours and avoid long runs at full throttle. Change the oil at the first interval in the manual. With only 700 mL of oil in the sump, the early oil change matters.

Service Intervals in Plain English

• Engine oil: once a year, or at the hours the manual gives.
• Gear oil: once a year. Look for milky or metallic oil.
• Spark plug: replace on schedule, check the gap.
• Impeller: every two to three seasons.
• Anode: replace when half gone.
• Valve clearance: check when the manual says.
• Fuel filter and lines: look for cracks and softness.

If you are not confident, a local mechanic can do this in under an hour. The Suzuki DF6AS5 for sale is easy to service because everything is accessible.

When Something Goes Wrong

Hard to start. Fresh fuel, new plug, check the choke and the stop lanyard.

Rough idle. Stale fuel in the carburetor. Drain it and clean the jets.

Dies at speed. Fuel starvation. Check the tank vent, the filter and the fuel line.

Overheating. Weak water stream, worn impeller or blocked outlet.

Vibration. A bent prop or loose clamp.

Dinghy Cruising With the Suzuki DF6AS5 for sale

Plenty of owners use a 6 HP as the main motor on a dinghy that serves a yacht, a houseboat or a waterside cabin. The days follow a pattern: load the boat, run across the anchorage, bring home shopping, ice and people. On that sort of work the motor needs to start at once, idle without stalling and be easy to lift.

The Suzuki DF6AS5 for sale does all of that. Because it is a carburetted single, there is nothing to power up before the first pull. No battery, no key and no computer. You carry spare fuel and a spare plug and you are covered.

Load matters more than people expect. Four adults and a week of provisions will keep a small dinghy in displacement mode, and the motor will push it at a steady walking-plus pace. That is fine. Plan the trip for the speed you will actually get, not the speed in the brochure.

Beach Launching and Shallow Landings

If you land on beaches, the shallow water drive and the manual tilt are your friends. Tilt the motor up as you approach, drop it a notch for a bit of drive in shallows, and lift it clear before the boat touches. Rinse sand off the gearcase afterwards, because it grinds the impeller and the seals.

Do not run the motor at speed over sand. The water intake sits just above the skeg and will pull in grit. Better to stop, raise the motor and paddle the last stretch than to wear out an impeller in a day.

Camping and Expedition Use

Anglers and campers carry the Suzuki DF6AS5 for sale to remote lakes in a vehicle, on a trailer, even on a pack animal. The motor is compact and the carrying handle is built into the cowl. Strap it upright in a vehicle, or lay it on the side marked for storage with an old blanket underneath.

On a remote trip, pack the small spares list: plug, prop, shear items where fitted, a bottle of oil, a few feet of fuel hose and some cable ties. Take a small funnel and a clean filter cloth for fuel. Remote fuel is often dirty, and a cloth saves the carburetor.

Fitting an Extended Fuel Supply

Many people choose a 3 gallon tank for this motor, and the Suzuki DF6AS5 for sale accepts it through the external fuel connection fitted to the motor. Route the hose so it does not kink under the transom clamp. Keep the tank low and level, and secure it so it cannot slide in a turn.

Ventilation matters. If the tank vent is shut, the motor starves of fuel and loses power after a few minutes. Open it, and if the vent is blocked, clear it with a pin.

Choosing Between Short and Long Shaft

The choice is rarely close. Measure the transom and pick the matching shaft. Fitting a long shaft motor on a short transom drags the gearcase and wastes power. Fitting a short shaft on a tall transom pulls air into the prop and makes the boat run poorly.

Some owners try to get round it by raising or lowering the transom with spacers or by fitting a motor bracket. A bracket is fine on a sailboat or a yacht tender, but on a small dinghy it changes the balance. If you are in doubt, send us the transom measurement and the boat type. The Suzuki DF6AS5 for sale is the right choice only when the numbers say so.

What Wears Out First

Experience from small motors shows a pattern. The first parts to need attention are not the engine internals. They are the propeller, the water pump impeller, the spark plug, the fuel hose and the pull cord. Look after these and the Suzuki DF6AS5 for sale goes on for years.

Props get chipped on stones, and a chipped prop sets up vibration. Impellers harden and crack with age, and a cracked impeller gives weak cooling. Fuel hoses get brittle in the sun. Pull cords fray where they pass the housing. All are cheap and all can be changed at home.

Cleaning and Cosmetic Care

Wash the cowl with fresh water and mild soap. Dry it and apply a thin coat of marine wax if you like. Avoid solvent cleaners on plastic parts. Check the decals and replace them if they peel, because they carry the warnings and the filling instructions.

Inside the cowl, wipe the engine with a damp cloth and check for leaks and loose wires. Use a light corrosion spray on bare metal. Do not spray the carburetor or the ignition parts.

Insurance, Registration and Paperwork

Keep the invoice, the serial number and photos of the motor. For boats that must be registered, check whether the motor needs to be listed. In some countries a motor of this size is exempt, in others it is not. Ask your local authority. We give you an invoice and export documents with every shipment, and the serial number is on the motor and in the paperwork.

Common Mistakes With a New Motor

• Running it dry of oil. Check the dipstick before the first start.
• Running it out of water on the muffs. A few seconds can destroy an impeller.
• Laying it on the wrong side, so oil runs into the cylinder.
• Forgetting to open the tank vent.
• Leaving old fuel in the carburetor for months.
• Not tying a safety line to the transom.

Avoid these and the Suzuki DF6AS5 for sale will give you very little trouble.

The 6 HP Compared With Others

A smaller 4 HP, such as the Suzuki DF4AS5, is lighter but has less power for loaded boats. A 9.9 HP like the Suzuki DF9.9BS5 pushes harder but costs more and weighs more. The Suzuki DF6AS5 for sale stays in the middle: light enough to carry easily and strong enough for ordinary jobs.

Black or White?

The black cowl is the standard finish. If you prefer white, the same motor is listed as the Suzuki DF6ASW5 in the later series and the Suzuki DF6ASW2 in the earlier series. The engines are the same, and only the cowl colour changes.

Cold Starts and Hot Days

In cold weather the Suzuki DF6AS5 for sale wants the choke and a patient hand. Let it idle for a minute or two before you engage gear, because cold oil is thick and a cold carburetor leans out when you open the throttle. In hot weather, the main risk is vapour in the fuel line. Keep the tank out of direct sun, and if the motor stalls hot, wait a minute before trying again.

Warranty and Support

The Suzuki DF6AS5 for sale ships with Suzuki factory warranty paperwork. Terms depend on your region, so ask us what applies where you live. Keep your invoice and a service record. If you have a question after the motor arrives, write to us and we will help you sort it out, whether it is a setup question or a parts question.

Packing Notes

The motor travels upright or on its side in the carton, with padding. When it arrives, open the box in front of the courier if you can, and check for damage. Take photos if the carton looks crushed. Check the oil level before the first start.

Shipping Your Motor

The motor goes out in its factory carton. We book freight to your country by sea or air and send you a written delivery quote before payment. Once dispatched you get tracking and the documents needed for customs. If you have your own shipper, we can hand the motor to them.
