Suzuki 15 HP DF15AES5 Outboard Motor

Description

The Suzuki DF15AES5 for sale on this page is a brand new 15 HP Suzuki four stroke with electric start, a tiller handle and a 15 inch short shaft. It comes in the sealed factory crate, the price is shown on the page, and we ship it worldwide with a delivery quote before you pay anything.

This is the 15 you buy when you are tired of pulling a cord. You turn the key or press the button on the tiller and it runs. The pull rope is still there under the cowl if the battery ever goes flat, so you are never stuck. For a small aluminium boat, an inflatable or a dinghy with a short transom, it is one of the easiest motors in the class to live with.

Below we go through the model code of the Suzuki DF15AES5 for sale, the boats it fits, the full spec sheet, what you need to buy besides the motor, break-in, servicing and the small problems we see on these engines. It is written from the counter side of the shop, so it is plain and practical.

What the Model Code on the Suzuki DF15AES5 for Sale Means

Suzuki model codes look like alphabet soup until someone reads them out for you. Here is the code on the Suzuki DF15AES5 for sale, piece by piece.

• DF means a Suzuki four stroke outboard.
• 15 is the rated power, 15 HP.
• A is the generation. The A series 15 is the fuel injected model with Lean Burn, which replaced the older carburetted DF15.
• E is electric start. You get a starter motor, a charging circuit and a battery cable loom.
• S is the short shaft, made for a transom of about 15 inches.
• 5 is the current production series. It tells the dealer which run the motor comes from. It does not change the horsepower or the shaft.

What is missing from the code also matters. There is no T, so there is no power tilt. There is no L, so it is not the 20 inch shaft. There is no W, so the cowl is the standard dark colour. The Suzuki DF15AES5 for sale is the plain tiller, short shaft, key start version of the DF15A.

Boats That Suit the Suzuki DF15AES5 for Sale

Short shaft motors fit boats with a low transom. That usually means inflatables, rigid inflatable tenders, small jon boats, car top tinnies, dinghies and some canoes with a square stern. Measure first, then decide. We cover that further down.

On a 12 to 14 foot aluminium boat with two people and some gear, the Suzuki DF15AES5 for sale planes without drama. On a 3.3 to 3.8 metre inflatable with a hard floor it is a good match, and the 15 is often the highest rating those boats carry. Check the capacity plate on your hull. Never hang more power than the plate allows. The Suzuki DF15AES5 for sale is legal on any hull plated for 15 HP or more.

Customers who pick electric start over the plain manual model tend to fall into a few groups. Older owners who do not want to yank a cord. Anglers who stop and start the motor all day while drifting. People who already carry a battery for a fish finder or lights. And families where more than one person drives the boat. If any of that sounds like you, the Suzuki DF15AES5 for sale makes sense.

It is less suited to a boat that sits high out of the water at the stern. A 20 inch transom needs the long shaft version. It is also not the right motor if you need to drive from a console. For that look at the remote models. Within its lane, though, the Suzuki DF15AES5 for sale is about as easy as a 15 gets.

Suzuki DF15AES5 for Sale: Full Specifications

Weights vary a little depending on where you read them, so treat the figure as close, not exact. Suzuki lists its whole portable range on the Suzuki 2.5 to 30 HP outboards page if you want to compare models side by side.

Features That Matter on the Suzuki DF15AES5 for Sale

Fuel Injection With Lean Burn

There is no carburettor and no choke on the Suzuki DF15AES5 for sale. The ECU reads air temperature, engine temperature and throttle position and meters the fuel. Cold starts are quick. Warm restarts are quick. You do not flood it.

Lean Burn is Suzuki’s way of trimming fuel at cruise. When you hold a steady part throttle, the mixture runs leaner. On a full day of fishing the Suzuki DF15AES5 for sale uses noticeably less fuel than the old carburetted 15 did. Customers who switch from a two stroke often tell us one tank lasts them twice as long.

Injection also means no carb to gum up over winter. Bad fuel can still hurt it, but it is far more forgiving than a small carburettor jet.

Electric Start With a Backup Cord

The starter is a proper 12 volt motor. Press the button, it fires. If the battery is dead, open the cowl area and use the pull rope like a manual model. We like that. Plenty of electric start motors elsewhere have no rope, and that is a long paddle home.

The Suzuki DF15AES5 for sale also has a 12 amp charging output. That is enough to top the battery up while you run and to feed a small fish finder or navigation lights.

Tiller Handle and Controls

The tiller on the Suzuki DF15AES5 for sale has a twist grip throttle with a friction screw, a stop switch with lanyard, and the start button. The shift lever is at the front of the motor, so you reach forward to select gear. A start in gear lockout means it will not crank unless it is in neutral.

Decompression and Shallow Water Drive

An automatic decompressor makes the pull cord light if you ever need it. Shallow water drive lets you lock the leg partly up and creep over sand flats or weed at low speed without dragging the skeg.

Warning Systems

Low oil pressure, overheating and over rev all trigger the protection system. The engine drops its revs and a lamp tells you something is wrong. That has saved more than one Suzuki DF15AES5 for sale from a cooked head when a plastic bag blocked the intake.

Rigging the Suzuki DF15AES5 for Sale: What Else You Need

Tiller motors are simple to rig, and the Suzuki DF15AES5 for sale is no exception, but electric start adds a few things to the list. Here is what to plan for.

• Battery. Not included. A 12 volt marine starting battery of about 400 to 500 CCA is plenty. Put it in a battery box and strap it down.
• Battery cables. The motor has a lead for the battery. Check the length reaches your battery box. Add a fuse or isolator switch if you run other electrics.
• Fuel tank and line. The portable tank and hose come in the crate. Keep the hose clear of sharp edges.
• Transom clamps. The motor clamps on with screw handles. On an inflatable we also suggest a safety chain or a bolt through the transom bracket.
• Propeller. The stock 9 inch pitch suits most light boats. A heavier boat or a tender that carries four adults may want a lower pitch.
• Safety kit. A spare lanyard, a spare spark plug and a paddle. Cheap items that end a bad day early.

If you are pairing the Suzuki DF15AES5 for sale with a boat that already has a battery for electronics, run a separate starting battery or use a dual battery switch. That way a long day of sounder use never leaves you unable to start.

Measuring Your Transom for a Short Shaft

Measure from the top of the transom, where the motor clamps sit, straight down to the bottom of the hull. Do it on the centre line, not at an angle. Getting this right is the single biggest thing you can do before you buy a Suzuki DF15AES5 for sale.

• About 15 inches: short shaft. This is the Suzuki DF15AES5 for sale.
• About 20 inches: long shaft. You need the L version.
• Somewhere between: talk to us before you order.

When the motor is mounted, the anti ventilation plate above the prop should sit level with the bottom of the hull or up to an inch below. Too high and the prop sucks air and the motor over revs in turns. Too low and you drag the leg and lose speed. Most inflatables are built for a short shaft, but some larger tenders are not, so do not guess.

Break-In for the First 10 Hours

Every new outboard needs a gentle start, and the Suzuki DF15AES5 for sale is no different. Suzuki’s break-in is short and simple. Follow it and the rings seat properly.

1. First 2 hours: run at no more than half throttle. Vary the speed. Do not hold one rpm for long periods.
2. Next 1 hour: up to about three quarter throttle, with short bursts of full throttle allowed.
3. Up to 10 hours: normal use, but avoid long runs flat out.

Check the oil level before each early outing. After the first 20 hours, or the first month, change the engine oil and gear oil. That first service flushes out the tiny bits of metal that every new engine sheds. It is the cheapest insurance you will ever buy for your Suzuki DF15AES5 for sale.

Maintenance Schedule for the Suzuki DF15AES5 for Sale

Here is the schedule we give customers. Your owner’s manual is the final word, and intervals can be shorter in hot or salty climates.

Battery care is the extra job on an electric start motor. Keep the terminals clean and tight. Charge it over winter. A weak battery is the most common reason a Suzuki DF15AES5 for sale cranks slowly in spring.

Use genuine parts where you can. Suzuki’s own genuine parts and accessories range covers oil, filters, anodes, impellers and props for this motor.

Salt Water Care

The Suzuki DF15AES5 for sale is rated for salt water. It has a multi layer corrosion coating and sacrificial anodes. That does not mean you can forget about it.

• Flush after every salt trip. There is a flushing port, so you do not need ear muffs. Run fresh water through for 5 to 10 minutes.
• Rinse the outside, including under the tiller and around the clamp brackets.
• Tilt the motor up when moored so the leg is out of the water.
• Check anodes every few months. Replace when they are half gone. Never paint them.
• Spray a corrosion block product under the cowl once a month in the season.
• Wipe the battery terminals. Salt air eats them fast.

Owners who do these few things find their motor still looks good after years in salt water. Owners who skip them call us about seized clamp screws and white crust round the cowl latch.

Common Issues and Simple Fixes

These are the calls we get most about small Suzuki EFI motors. None of them are serious. Most are fixed in ten minutes, and none of them are faults in the Suzuki DF15AES5 for sale itself.

Cranks but will not start

Check the lanyard clip is on the stop switch of the Suzuki DF15AES5 for sale. Squeeze the primer bulb until it is firm. Make sure the tank vent is open. Then check the fuel is fresh. Old fuel is the number one cause. Fuel left in a tank for three months can stop a Suzuki DF15AES5 for sale from starting cleanly.

Starter clicks but does not turn

Almost always the battery or a loose terminal. Charge the battery, clean the terminals and try again. You can still pull start the Suzuki DF15AES5 for sale in the meantime.

Weak tell tale stream

The little pee hole often blocks with salt or sand. Poke it clear with a piece of wire. If the stream is still weak and the motor runs hot, the impeller may need replacing.

Motor revs high but the boat is slow

Ventilation. Either the shaft is too short for the transom or the motor is trimmed too far out. Move the tilt pin one hole in and check your mounting height.

Rough idle after storage

Stale fuel or water in the filter. Drain the tank, refill with fresh fuel and check the water separating filter if you have one fitted.

How It Compares With Its Siblings

We sell the whole small Suzuki family, so here is how the Suzuki DF15AES5 for sale sits next to its neighbours.

• Suzuki DF15AS5: same engine and shaft, manual start only. Lighter, cheaper, battery free EFI. Good if you never want to carry a battery.
• Suzuki DF15AEL5: electric start like this one, but the 20 inch long shaft for higher transoms.
• Suzuki DF15ATHL5: tiller, long shaft, with power tilt. Nice on a heavier boat.
• Suzuki DF9.9BES5: the 9.9 HP electric start short shaft. Same size block, less power. Pick it if a 10 HP limit applies on your water.
• Suzuki DF20AES5: 20 HP, electric start, short shaft. Worth it if your hull is rated for 20 and you carry loads.

For most people choosing between 9.9, 15 and 20, the deciding factor is the capacity plate on the boat and any local horsepower rule. Within those limits, the 15 hits a sweet spot of weight and power. You can browse all of them in our 15 HP Suzuki outboards and the wider Suzuki outboard range.

Suzuki DF15AES5 for Sale: Questions We Get

Can I start the Suzuki DF15AES5 without a battery?

Yes. It keeps the manual pull cord. With a flat battery, pull start it and the alternator will begin charging once it runs. You still need a battery to use the push button.

Is it heavy to carry?

At about 106 lb the Suzuki DF15AES5 for sale is a two person lift for most people. There is a carry handle at the back of the cowl. Many owners leave it on the boat and lock it.

How much fuel does it use?

At cruise on a light boat, roughly 3 to 4 litres an hour. Full throttle is more. Lean Burn helps most at steady part throttle.

Does it need a special oil?

No. The Suzuki DF15AES5 for sale runs on a good four stroke marine oil, and a typical choice is 10W-30 or 10W-40. Change it every 100 hours or once a year.

Can I add power tilt later?

Not really. If you want power tilt on a 15, order the T model from the start. It is a different bracket.

Is the Suzuki DF15AES5 for sale suitable for an inflatable?

Yes, as long as the inflatable is rated for 15 HP and the transom is short shaft height. It is one of the most popular motors for 3.3 to 3.8 metre tenders.

How long does delivery take?

It depends on where you are and how the Suzuki DF15AES5 for sale is shipped. Air freight is often one to two weeks, sea freight longer. We give you the timeline with the quote.
