Suzuki 15 HP DF15AS5 Outboard Motor

Description

If you want a light, simple 15 HP that needs no battery at all, the Suzuki DF15AS5 for sale here is the one. It is a new pull start Suzuki four stroke with fuel injection, a tiller handle and a 15 inch short shaft, shipped in the factory crate. The price is on this page and we deliver worldwide, with the freight cost agreed before you pay.

We sell a lot of the Suzuki DF15AS5 for sale to people who own inflatables and small tinnies. They like that the motor is self contained. Clamp it on, connect the fuel line, give it a pull, and go. No wires, no battery box, nothing to go flat over the winter.

Why People Choose the Suzuki DF15AS5 for Sale

The short answer is weight and simplicity. At about 97 lb, the Suzuki DF15AS5 for sale is the lightest way to get 15 horsepower from Suzuki. The electric start model is roughly 9 lb heavier before you add a battery, and a battery adds another 25 to 35 lb to the boat.

The fuel injection on this motor is battery free. It powers itself from the flywheel the moment you pull the cord. That was not possible on small outboards a few years ago. It means the Suzuki DF15AS5 for sale starts like an EFI engine, quick and without a choke, yet it carries no electrical baggage.

The Suzuki DF15AS5 for sale also costs less. The gap between manual and electric start pays for a decent spare prop and a season of oil.

Reading the Code: DF15AS5

Each part of the name tells you something about the Suzuki DF15AS5 for sale.

There is no E, so it is manual start. There is no T, so tilt is by hand. And there is no W, so the cowl is the standard colour rather than white. If you need white, we stock the Suzuki DF15ASW5, which is otherwise the same motor.

The Boats It Fits

The Suzuki DF15AS5 for sale is built for boats with a low stern. In our experience these are the usual homes for it:

• Inflatable tenders and RIBs from about 3.2 to 3.8 metres.
• Aluminium dinghies and car top boats from 10 to 14 feet.
• Small jon boats used on rivers and lakes.
• Square stern canoes and some fishing kayaks with a motor mount, if rated for the weight.
• Yacht tenders that get lifted on and off a davit.

With one or two people aboard, a light boat gets on the plane easily with the Suzuki DF15AS5 for sale. With four adults in an inflatable it will still plane, but slower to get there, and a lower pitch prop helps. Always check the maximum power on your hull plate first.

The Suzuki DF15AS5 for sale is not for a boat with a 20 inch transom. It is not for console steering. And if you want to run lights or a big fish finder off the motor, you need to add the charging kit or choose an electric start model.

What It Is Like to Run

Starting

Put the Suzuki DF15AS5 for sale in neutral. Squeeze the primer bulb until firm. Clip the lanyard on. Pull. There is no choke to set because the EFI handles it. A decompressor lowers the effort on the cord, so even smaller owners start the Suzuki DF15AS5 for sale without trouble. Most of the time it goes first or second pull, cold or hot.

Driving

The twist grip throttle on the Suzuki DF15AS5 for sale has a friction adjuster. Set it so the throttle stays where you leave it. The steering friction screw does the same for the tiller. On a long run you can let go for a moment to grab a drink and the boat holds its line.

Gear changes are on a lever at the front of the motor. You reach forward, pull it into forward or back into reverse. Shifting is light and positive. The engine will not start in gear, which is a good thing.

Noise and fuel

The Suzuki DF15AS5 for sale is one of the quieter 15s on the water. Exhaust goes out through the prop hub. At trolling speed you can talk at a normal level. The Lean Burn system cuts fuel use at steady cruise, so a single tank goes a long way. On a typical half day of fishing the Suzuki DF15AS5 for sale often uses less than half a tank.

Things to Buy With the Suzuki DF15AS5 for Sale

A manual tiller motor like the Suzuki DF15AS5 for sale needs very little extra. That is part of the appeal. Here is our short list.

• A spare propeller. Rocks and sand bars are real. Keep a spare in the boat.
• A spare spark plug and the plug spanner from the tool kit.
• A spare lanyard. Without it the motor will not run.
• A motor lock for the clamp screws if the boat is left on a mooring.
• A transom pad or a motor bracket board on inflatables, so the clamps do not crush the transom.
• Fresh fuel stabiliser for storage.

No battery, no cables, no switch panel. If you later want to charge a small battery for a sounder, Suzuki sells a lighting coil kit that fits the Suzuki DF15AS5 for sale. Genuine kits and parts are listed in the Suzuki genuine parts and accessories catalogue.

Propeller Choices for the Suzuki DF15AS5 for Sale

The stock prop on the Suzuki DF15AS5 for sale is a three blade aluminium of 9.25 inch diameter and 9 inch pitch. That suits a light boat with one or two people. It is not right for everyone.

The rule is simple. At full throttle with your normal load, the engine should reach somewhere between 5,000 and 6,000 rpm. If it cannot get past 5,000, the pitch is too high for your boat, so go down. If it bangs into the rev limiter, the pitch is too low, so go up.

• Heavy inflatable or four adults: try a 7 or 8 inch pitch. You lose a little top speed but gain hole shot and push.
• Light aluminium boat, solo: the stock 9 inch is usually right. Some go to 10 or 11 inch for more top end.
• Yacht tender pushing against current: lower pitch again, as low as Suzuki offers for this motor.

We sell spare props for the Suzuki DF15AS5 for sale, and we can ship one in the same crate as the motor. That saves a second freight bill.

Carrying and Transporting the Motor

One reason people buy the Suzuki DF15AS5 for sale is that it can come off the boat. Some keep it in the garage. Some carry it on a car or in a van. A few tips from years of handling these.

• Use the carry handle at the back of the cowl and the front of the bracket. Two people make it easy.
• Transport it upright on a motor stand where you can. That is the safest position.
• If you must lay it down, follow the owner’s manual for the correct side. On the Suzuki DF15AS5 for sale the tiller should face up.
• Close the fuel connector and disconnect the line before moving it.
• Tie it down so it cannot slide into anything sharp. The cowl is tough but the tiller arm is exposed.

A wooden motor stand with a 2 by 10 inch board is cheap to build and keeps the motor upright in a shed or on a trailer.

Shaft Length: Measure Before You Buy

This is the one mistake we see more than any other with the Suzuki DF15AS5 for sale. Somebody buys a short shaft for a boat that needed a long shaft, or the other way round.

Here is the method. Stand at the stern. Put a tape on the top of the transom where the clamps will sit. Run it straight down the back of the transom to the bottom of the hull, keeping the tape vertical. Read the number.

• 14 to 16 inches: the Suzuki DF15AS5 for sale fits.
• 19 to 21 inches: you need the long shaft. Look at the Suzuki DF15AEL5 or ask us about a manual long shaft 15.
• A V shaped notch or a raised motor well: measure in the notch, where the motor actually sits.

When mounted, the cavitation plate should line up with the bottom of the hull or sit slightly lower. Fine tune with the tilt pin so the motor leg is vertical when the boat is moving with its normal load.

Breaking In a New Suzuki DF15AS5 for Sale

The first ten hours on a Suzuki DF15AS5 for sale shape how the engine wears for the rest of its life. Keep it easy.

• Hours 0 to 2: idle and low speed, no more than half throttle. Change speeds often.
• Hours 2 to 3: up to three quarter throttle, a minute or two at full is fine.
• Hours 3 to 10: normal running, avoid holding full throttle for long.

After 20 hours, change the engine oil and gear oil. That is the first service. Many owners skip it because the motor is new and running well. Do not skip it. The first oil carries the most wear metal.

Service Plan

Little Suzukis are easy to service at home. Most jobs need a few spanners and a drain pan. This is the plan we hand out with each Suzuki DF15AS5 for sale.

Gear oil on the Suzuki DF15AS5 for sale is a quick job. Drain from the bottom plug, refill from the bottom with a pump until it comes out of the top vent, then fit the top plug before the bottom one. If the old gear oil looks milky, water is getting in and the seals need a look.

Looking After It in Salt Water

The Suzuki DF15AS5 for sale is saltwater rated, with anodes and a multi layer paint system on the aluminium. Salt is still hard on any outboard. Most of the damage we see comes from skipped flushing.

1. Connect a garden hose to the flushing port after each trip. The motor does not need to run. Flush for about ten minutes.
2. Wash salt off the clamp screws, the tilt pin and the tiller pivot.
3. Keep the leg tilted up when the boat is parked in the water.
4. Look at the anodes at the start of each season. Swap them when about half is gone.
5. Spray an anti corrosion product on the powerhead once a month.

On yacht tenders that stay in a marina, we see the Suzuki DF15AS5 for sale last for many years when this routine is kept. Without it, clamp screws seize and paint starts to bubble at the bottom of the leg.

Winter Storage

If you lay the boat up for a few months, the Suzuki DF15AS5 for sale needs about half an hour of care before it goes to sleep.

1. Add fuel stabiliser to the tank and run the motor for ten minutes so treated fuel reaches the injection system.
2. Change the engine oil while it is warm. Old oil left in all winter carries acids.
3. Change the gear oil and look for any sign of water.
4. Flush with fresh water and let the leg drain fully, standing upright.
5. Spray a fogging or anti corrosion product under the cowl.
6. Store the motor upright in a dry place, covered but not sealed in plastic.

In spring, fit fresh fuel, check the plug and run it on the flushing port or in a test tank. A Suzuki DF15AS5 for sale stored this way normally starts on the first or second pull after months of rest.

Small Problems and How to Sort Them

Hard to pull or will not fire

Check the lanyard first. It sounds silly, but it is the most common reason. Then check the bulb is firm and the fuel tank vent is open. If the Suzuki DF15AS5 for sale still will not fire, try fresh fuel and a new plug.

Runs, then dies at idle

On a Suzuki DF15AS5 for sale this is usually stale fuel or a pinched fuel line. Make sure the line is not trapped under a seat or bent sharply. Replace fuel that is more than a couple of months old.

No water from the tell tale

Stop the Suzuki DF15AS5 for sale and clear the tell tale hole with a thin wire. If the stream does not come back, check the water intake grilles on the leg for weed or a plastic bag.

Over revs and loses grip in turns

On the Suzuki DF15AS5 for sale this means the prop is pulling air. Either the motor sits too high on the transom or it is trimmed out too far. Move it down or set the tilt pin one notch closer to the transom.

Vibration after hitting something

Check the prop on the Suzuki DF15AS5 for sale for bent blades. Even a small bend causes buzz through the tiller. Fit the spare and have the damaged one repaired.

Comparing the Suzuki DF15AS5 for Sale With Other Small Suzukis

We stock most of the small range, so it is easy to swap if another model suits you better. Here is how the nearest options compare with the Suzuki DF15AS5 for sale.

• Suzuki DF15AES5: same motor plus electric start and a 12 amp charging system. Heavier, and you need a battery.
• Suzuki DF9.9BS5: same block, tuned to 9.9 HP, manual start, short shaft. For waters with a 10 HP limit.
• Suzuki DF20AS5: 20 HP, manual start, short shaft, a little heavier. For bigger tenders rated for 20.
• Suzuki DF6AS5: much lighter 6 HP for small dinghies where weight matters most.

FAQ About the Suzuki DF15AS5 for Sale

Does the Suzuki DF15AS5 need a battery?

No. The EFI on the Suzuki DF15AS5 for sale runs without a battery. You start it with the pull cord and the flywheel powers the injection and ignition.

Can I charge a battery from it?

Not as standard on the Suzuki DF15AS5 for sale. Suzuki offers an optional lighting coil kit of about 6 amps. It is enough for a small sounder and nav lights.

How fast will it push my boat?

With the Suzuki DF15AS5 for sale on a light 12 foot aluminium boat with one person, around 20 mph is common. Heavier loads and inflatables are slower. Prop choice changes this a lot.

Is it OK to lay the motor down?

Yes, but only on the correct side with the tiller up, as shown in the owner’s manual. Laying it on the wrong side can let oil run where it should not.

What octane fuel does it need?

The Suzuki DF15AS5 for sale is happy on regular unleaded, 87 octane in the US system or 91 RON elsewhere. Fresh fuel matters more than high octane.

Can I fit a long shaft later?

It is not a practical conversion on the Suzuki DF15AS5 for sale. Buy the shaft length you need from the start.
