Suzuki 15 HP DF15ASW5 Outboard Motor

Description

We have the Suzuki DF15ASW5 for sale brand new, in the factory crate. It is Suzuki’s 15 horsepower two cylinder four stroke in white, with pull-cord starting, tiller steering, a 15 inch short shaft and manual tilt. The price is on this page and we ship worldwide.

This is the simplest outboard in the Suzuki 15 HP line. No battery to buy, no electric start to fail, no cables to route. Pull the cord and it runs. Buyers use it on jon boats, skiffs, small inflatables, dinghies and as a back-up kicker, and we quote delivery to your door before you pay anything.

Below you get the full specifications, what each letter in the model code means, which boats suit it, how to rig it, how to run it in and how to look after it. If you are comparing it with the electric start versions, that is covered too.

Suzuki DF15ASW5 for sale: Specifications

Production runs can differ slightly, so the paperwork in the crate is the final word. Suzuki shows the whole small outboard family on its official 2.5 to 30 HP outboard page if you want to compare models.

Reading the Suzuki DF15ASW5 for sale Model Code

DF is Suzuki’s four stroke prefix. 15 is the horsepower. The A tells you it belongs to the current generation of small Suzuki engines. S means a 15 inch short shaft. W means a white cowl instead of black. The 5 at the end is the production series.

What is missing matters as much. There is no E, so no electric start. There is no T, so no power tilt. There is no H, because on this size the manual tiller is already the base setup. There is no L, so the shaft is not the 20 inch one. If you want any of those, look at the other 15 HP listings further down this page.

Why Buyers Pick the Suzuki DF15ASW5 for sale

Weight is the first reason. At about 97 lb it is one of the lightest 15 HP four strokes you can buy. One person can lift it from the car to the boat, and that matters if you launch off a beach or a ramp alone.

The second reason to choose the Suzuki DF15ASW5 for sale is the starting system. Suzuki’s fuel injection on this engine works without a battery. A small generator inside the flywheel powers the injectors and the ignition while you pull the cord. In practice the motor lights after a couple of pulls, hot or cold, and you never touch a choke.

The third is noise and smoke. A two stroke of this size is loud and leaves a blue haze behind the boat. This one idles quietly and the exhaust goes through the prop hub, so most of the sound stays underwater.

Boats That Suit the Suzuki DF15ASW5 for sale

Jon boats and aluminium skiffs

A 14 to 16 foot flat bottom with a 15 inch transom is the classic match. Check that the transom really is a short one, because many aluminium boats are built for 20 inch shafts.

Small inflatables and RIBs

Rigid inflatable boats up to about three metres, and larger soft-bottom inflatables, can carry it without trouble. Look at the maximum power plate on your boat first.

Dinghies and tenders

Yacht tenders get a lot out of a light engine. The white cowl also looks right on a white hull.

Kicker motor on a bigger boat

Plenty of anglers keep a 15 on the transom as a trolling motor and a get-home option. Pull-cord starting means it works even when the main battery is flat.

The Suzuki DF15ASW5 for sale Compared With Its Neighbours

Suzuki builds the 15 and the 20 on the same 327 cc block, and the weights Suzuki lists are the same for both. That makes the choice partly about rules and partly about money. Some regions limit tiller boats to 15 HP for licensing or for the boat plate, and the 15 is the one to buy there.

If your boat is rated higher and you want a bit more push, the Suzuki DF20ASW5 is the same white, short shaft, pull-start package at 20 HP. Going the other way, the 9.9 HP range is lighter still, for example the Suzuki DF9.9BTHLW5.

How the Suzuki DF15ASW5 for sale Behaves on the Water

The Suzuki DF15ASW5 for sale comes up on the plane willingly with a light load. Two adults and some gear in a 14 foot aluminium boat is no problem. Add four people and a cooler and the boat will still move, but it will take longer to plane and you will want the weight spread forward.

Throttle is a twist grip on the handle with a tension screw so your hand can rest. Gear shift is a lever on the front of the cowl. The steering friction control lets you set how loose or tight the tiller feels, which helps on a long day.

We will not quote speeds. They depend on hull shape, load, prop pitch and how the boat is trimmed. What we can say is that the motor is happy through its 5,000 to 6,000 rpm range and does not feel strained.

Manual Start Facts for the Suzuki DF15ASW5 for sale

Some people are nervous about pull-cord starting. At 327 cc with fuel injection it is not hard work. Put the lever in neutral, clip on the lanyard, squeeze the primer bulb if the fuel line has been disconnected, and pull firmly along the line of the cord.

If it fails to start after a few pulls, stop and check before you keep going. The usual causes are a lanyard that is not clipped in, a gear lever not in neutral, a closed tank vent or an old tank of fuel. Fix that and it normally fires on the next pull.

Anyone with a bad shoulder, or who runs the motor many times a day, is better off with the Suzuki DF15AES5, which adds electric start to the same short shaft package.

Rigging the Suzuki DF15ASW5 for sale

Rigging the Suzuki DF15ASW5 for sale is easy. You need a fuel tank and line with the right connector, a propeller, and a transom that can carry the load. The Suzuki DF15ASW5 for sale has no remote controls, no key switch and no harness to fit.

Measure the transom from the top edge to the bottom of the hull. For a 15 inch shaft you want about 15 inches. Clamp the motor, then tighten the clamp screws firmly. Many owners add a small safety cable or chain between the motor and the boat. It costs almost nothing and a lost motor costs a lot.

Set the motor so the anti-ventilation plate sits level with the bottom of the hull, or a fraction above it on a flat bottom boat. If you see the prop blowing out in turns, lower the motor a little. If you get heavy spray and drag, raise it.

Propeller Choice for the Suzuki DF15ASW5 for sale

Suzuki lists a standard propeller for the engine family and a high thrust one for heavier boats. The right choice is the one that lets the motor reach the top of its rpm range with your normal load. If it cannot get to 5,000 rpm at full throttle, the prop is too big in pitch for the boat. If it screams past 6,000, it is too small.

Heavily loaded work boats and big inflatables often do better with the high thrust prop. Light skiffs usually want the standard one. Tell us the boat, the load and the water you run in and we will suggest a starting point. Genuine props and spares are listed on the Suzuki genuine parts and accessories page.

Running In the Suzuki DF15ASW5 for sale

Follow the break-in section of the owner’s manual. The general idea is simple. Do not hold full throttle for long periods in the first hours, vary the revs, and let the motor warm up properly before you load it. Change the engine oil and the gear oil at the first service interval in the manual, because that is when the first wear metals come out.

An engine run in like this uses less oil and starts easier for the rest of its life. It costs you an hour or two of gentle driving.

Looking After the Suzuki DF15ASW5 for sale

• Flush with fresh water after every trip in salt, brackish or muddy water, using the flushing port.
• Change the engine oil and filter on the schedule in the manual, or at least once a year. The sump holds only about a litre, so use the right grade.
• Change the gear oil every season and look for milky oil, which means a leaking seal.
• Replace the water pump impeller every two or three seasons, sooner if you run in sand.
• Check the anodes and replace them when about half gone.
• Replace fuel filters and keep fuel fresh. Ethanol blends go stale quickly in a small tank.
• Check the spark plugs and the valve clearance at the intervals in the manual.

Small outboards like the Suzuki DF15ASW5 for sale are cheap to run because parts are common. Filters, plugs, impellers and anodes are normal Suzuki stock in most countries.

Salt Water Use of the Suzuki DF15ASW5 for sale

Suzuki rates the Suzuki DF15ASW5 for sale for salt water and uses a multi-layer corrosion finish. That does not mean you can ignore it. Salt dries into every crevice. Flush for a few minutes after each outing, wipe the cowl, and tilt the motor up when the boat is moored so the gearcase is out of the water.

A light spray of corrosion inhibitor under the cowl every few months helps the electrical connections. White paint shows up salt marks faster than black, so a quick wipe also keeps it looking new.

Storage Between Seasons

Run the Suzuki DF15ASW5 for sale on fresh water, let it drain upright, then store it standing or tilted according to the manual. Never lay a four stroke on its side with oil in the sump unless the manual says that position is allowed. Oil can run into the cylinders and cause trouble at the next start.

For long storage, add stabiliser to the fuel or run the carburettor-free injection system dry of old fuel, change the oil, and cover the motor. In cold places drain all water from the cooling system before frost.

Common Problems and Quick Checks

Will not start. Check the lanyard, neutral, fuel tank vent and fuel line connection. Squeeze the primer bulb until it is firm.

Runs, then stalls. Often a blocked tank vent or dirty fuel. Open the vent, check the filter and bulb.

Weak water stream from the tell-tale. Clear the outlet with a thin wire. If it stays weak, check the impeller before you run hard.

Will not reach full revs. The prop is probably too big, or the boat is overloaded. Check the prop first.

Warning light or alarm. Slow down, check the cooling water and the oil level, and do not keep running with the alarm on.

Is the Suzuki DF15ASW5 for sale Right for Your Boat?

Start with the plate on the boat before you buy the Suzuki DF15ASW5 for sale. It shows the maximum horsepower and often a maximum engine weight. At 97 lb this motor will sit well under almost any limit for a boat that takes 15 HP. If the plate says 10 HP, do not fit a 15 just because it bolts on. Insurance, licensing and common sense all point the same way.

Next, think about how you actually use the boat. A day of fishing a lake, a run between a mooring and a beach, or a few hours towing a dinghy train all suit this engine. Long daily commercial running at full throttle is a different job, and a bigger motor with electric start and a larger charging system will treat you better.

Fuel and Oil Basics for the Suzuki DF15ASW5 for sale

Use clean unleaded petrol of a normal pump grade for your region. Check the owner’s manual for the minimum octane, and avoid fuel that has sat in a can for months. Small tanks are the weak point on boats like this, because a tank that is used once a week lets fuel age.

Engine oil is a standard four stroke grade as listed in the manual. The sump is small, about one litre, so even a slightly low level matters. Check it with the motor upright and level, before every outing in the first month, then every few trips. There is no oil mixing, which is the big change if you are coming from a two stroke.

Carrying and Launching the Suzuki DF15ASW5 for sale

There is a carrying handle built into the cowl. Use it with the motor upright and the throttle in the neutral position. Do not lift by the tiller or the cowl latch. Two people make it easy when you are wading, and one person can manage on a dry ramp.

When you mount it on a dinghy hanging from davits or stored on a yacht rail, keep it upright with the clamp screws tight. A four stroke carried on its side can leak oil into the cylinders, so if you must move it by car, follow the manual on how to lay it down and keep it that way until you are home.

Spares Worth Keeping With the Suzuki DF15ASW5 for sale

A spare spark plug, a spare propeller with a nut and split pin, a fuel filter, and a small bottle of gear oil cover most of the faults you will meet on a trip. A basic tool roll with a plug spanner is enough. None of it is expensive, and any of it can save a day on the water.

If you buy the Suzuki DF15ASW5 for sale for a remote location, add an impeller kit and a gasket set to the order. Shipping a small box with the motor costs far less than shipping it later.
