SUZUKI 25 HP DF25AES2 OUTBOARD MOTOR

Description

The Suzuki DF25AES2 for sale on this page is a brand new 25 HP four stroke with a 15 inch short shaft, tiller steering, push button electric start and a pull rope as backup. It comes sealed in the Suzuki factory crate, the price is listed right here, and we ship it worldwide with a delivery quote before you pay a cent.

We have sold a lot of these over the years. People who buy the Suzuki DF25AES2 for sale here are usually tired of yanking a cord on a cold morning, or they have a shoulder that does not like pull starting anymore. The Suzuki DF25AES2 for sale is the same light three cylinder motor as the manual version, just with a key and a starter.

What the Suzuki DF25AES2 for sale model code tells you

Suzuki codes look like alphabet soup until somebody explains them once. Here is how we read the code on the Suzuki DF25AES2 for sale, letter by letter:

• DF: Suzuki four stroke outboard.
• 25: 25 horsepower at the prop shaft rating, about 18.4 kW.
• A: the A generation, the three cylinder, battery-less fuel injected design.
• E: electric start. It still has a recoil starter on the front as backup.
• S: short shaft, 15 inches, for a 15 inch transom.
• 2: the version suffix Suzuki uses for this production series.

There is no T in the code, so there is no power trim and tilt. You tilt it by hand with the tilt lever and set the angle with the trim rod. There is no W, so it is the standard dark Suzuki finish, not the white. And this is a tiller model, so you steer with the handle and do not need a cable steering system.

One thing customers ask: is the 2 a different motor from the 5 series we also list? The basic DF25A powerhead is the same. The suffix tracks the build version. If you are matching parts to an older motor in your fleet, tell us and we will check before you order the Suzuki DF25AES2 for sale.

Which boats suit the Suzuki DF25AES2 for sale

A short shaft 25 is a small boat motor. Think 12 to 16 foot aluminium boats with a 15 inch transom, rigid inflatables, smaller jon boats, dinghies for bigger yachts, and light skiffs. Measure first, then decide. We cover that further down.

Where the Suzuki DF25AES2 for sale really earns its price is on boats where you sit in the back and run the tiller all day. Duck hunters, river fishermen, people running out to moorings, small rental fleets. The electric start means you can kill the motor between drifts and restart it with a twist of the key instead of a pull.

It is not the right pick if you want to steer from a centre console with a wheel. For that you want a remote model like the Suzuki DF25ATS2. Also, if your transom is 20 inches, a short shaft will ride too high and cavitate. Do not try to make it work with a jack plate unless you know what you are doing.

Typical loads and speeds

On a 14 foot aluminium boat with two adults and gear, a well propped Suzuki DF25AES2 for sale will usually plane easily and run in the low to mid twenties in mph. A heavier 16 footer with four people will get on plane but slower. Inflatables with a hard floor respond really well to this motor because it is light for a 25.

Always check the capacity plate on your boat. If it says 20 HP max, do not hang a 25 on it. Insurance companies look at that plate first after an accident.

Suzuki DF25AES2 for sale: full specifications

These are the figures for the Suzuki DF25AES2 for sale as Suzuki publishes them for the DF25A family. Weights are dry, without prop and oil.

If you want the official family page, Suzuki keeps the DF25A and DF30A data on the Global Suzuki marine site. The figures above match it.

Features that matter on this motor

Battery-less fuel injection

The fuel injection system runs off the motor’s own power once it is turning. On the manual model that means no battery at all. On the Suzuki DF25AES2 for sale you need a battery for the starter, but if the battery dies you can still pull start it and the EFI will run fine. That backup has saved a few of our customers a long paddle home.

EFI also means no carburettor to gum up over winter. Carb motors that sit with old fuel are the number one reason small outboards come into a shop in spring. This one does not have that problem in the same way.

Lean Burn Control

Suzuki’s Lean Burn system reads engine conditions and leans the mixture at cruise. In practice the Suzuki DF25AES2 for sale burns noticeably less fuel at mid throttle than older carbureted 25s. Most owners see it in how long a tank lasts on a full day of fishing.

Three cylinders, light weight

A lot of 25s are twins, but not the Suzuki DF25AES2 for sale. The DF25A is a three cylinder, so it idles smoother and vibrates less through the tiller. Suzuki also uses an offset crankshaft and roller rocker arms to cut friction. You notice it at trolling speeds, which is where a small motor spends a lot of its life.

Three LED monitor and protection

On the front of the cowl there are warning lights for low oil pressure, overheating and over revving. The over rev limiter cuts in if the prop ventilates or you lift the motor while running. Simple, and it has stopped plenty of expensive mistakes.

Other details

• Freshwater flush port so you can rinse without muffs.
• Shallow water drive position on the tilt bracket.
• Front mounted shift lever, easy to reach from the seat.
• Suzuki anti-corrosion finish on the aluminium.
• Easy Start recoil that needs less pull than older designs.

Rigging the Suzuki DF25AES2 for sale: what else you need

Because it is a tiller model, rigging is easy. You do not need remote controls, cables or a steering helm. Here is the short list for the Suzuki DF25AES2 for sale:

• Battery: a 12V marine starting battery. Most customers use a small group 24. Keep it in a vented box with a strap.
• Battery cables: the motor comes with its harness for the battery. Check the length reaches where you want the battery.
• Fuel: the portable tank and fuel line, plus fresh fuel. Do not use fuel that has been sitting for months.
• Oil: the motor ships dry or with shipping oil depending on the batch. Always check the dipstick before first start.
• Prop: confirm the pitch suits your boat. We help with this before you order.
• Transom bolts: clamp screws hold it, but we always recommend through bolting on a 25 for safety.

If you are rigging a boat from bare, also budget for a kill cord, a fire extinguisher, and whatever safety gear your local rules need. Not our business to tell you the rules where you live, but do check.

Choosing the prop

The goal is to land at wide open throttle inside the 5,000 to 6,000 rpm range with your normal load. If the motor over revs past 6,000, go up in pitch. If it cannot reach 5,000, go down. Running a Suzuki DF25AES2 for sale under its rated rpm is hard on the motor, so do not ignore it.

Suzuki makes 3 blade props for the DF25A from about 9 to 15 inches of pitch. Light inflatables often want the higher end. Heavy loads, work boats and pushing barges want the lower end. Tell us your boat and we will suggest a starting point.

Measuring your transom before you buy

This is the step people skip, and it causes more returns than anything else. A Suzuki DF25AES2 for sale has a 15 inch shaft. Your transom needs to be about 15 inches for it to sit right.

1. Go to the centre of the transom, where the motor will clamp.
2. Measure straight down from the top of the transom to the bottom of the hull.
3. If you have a V hull, measure at the centre line, not at an angle.
4. Around 15 inches: short shaft. Around 20 inches: long shaft. Around 25: extra long.

The anti-ventilation plate above the prop should end up level with, or slightly below, the bottom of the hull. Too high and the prop sucks air. Too low and you get drag and spray. If your boat measures 20 inches, look at the Suzuki DF25ATHL2 instead.

Break-in for the first 10 hours

A new Suzuki DF25AES2 for sale needs a proper break-in. The rings need to seat, and the gears need time. Suzuki’s owner’s manual gives the details, but this is how we explain it to customers:

• First 2 hours: mostly at low speed, under half throttle. Brief bursts to get on plane are fine.
• Hours 2 to 3: up to about three quarters throttle. Vary the speed often.
• Hours 3 to 10: you can use full throttle for short periods, a minute or two. Keep changing rpm.

Do not run the Suzuki DF25AES2 for sale at one steady speed for an hour during break-in. That is the most common mistake. After the first 20 hours or so, Suzuki calls for the first service, which includes an oil change.

Maintenance schedule for the Suzuki DF25AES2 for sale

Small Suzukis are not fussy. Stick to this and the Suzuki DF25AES2 for sale will run for a very long time. Exact intervals are in the manual, and we suggest following it over anything you read online.

Use genuine filters and Suzuki oil where you can get them. You can find the parts list on the Suzuki genuine parts and accessories page. We also ship service kits with motors if you ask when ordering.

Battery care on the electric start model

A big chunk of the calls we get about the Suzuki DF25AES2 for sale are really battery problems. Keep the terminals clean and tight. If the boat sits for weeks, put a small charger or maintainer on it. The 14 amp charging system will top up the battery while running, but it is not designed to bring a dead battery back from flat.

Salt water care

This motor is built for salt water. The finish and the anodes are there for that reason. But salt still eats anything that is not looked after. Our routine for the Suzuki DF25AES2 for sale in salt water:

• Flush with fresh water through the flush port after every trip. Five to ten minutes.
• Rinse the outside, including under the cowl edge and the tilt bracket.
• Tilt it up when moored so the lower unit is out of the water.
• Check the anodes every few months. Replace them when half gone. Never paint them.
• Spray a corrosion inhibitor on the powerhead once a month in season.
• Grease the swivel bracket and tilt tube fittings regularly.

We see motors that are ten years old and look new, and motors that are three years old and look terrible. The difference is nearly always the fresh water flush.

Common issues and simple fixes

Most problems on a Suzuki DF25AES2 for sale are simple. Before you call anyone, check these:

It clicks but will not crank

Low battery or a loose cable. Also check the motor is in neutral. The start interlock will not let it crank in gear. And make sure the kill cord clip is on.

Cranks but will not start

Check the fuel tank vent is open, squeeze the primer bulb until it is firm, and make sure the fuel connector is clicked fully onto the motor. Old fuel is the next suspect.

No water from the telltale

Stop and look. Often it is just a blocked telltale hole. Poke it with a piece of wire. If it is still weak, the impeller may be worn, or there is a bag or weed over the intake.

Motor runs but boat will not plane

Usually the prop, trim angle or load. Try moving people forward, lowering the trim rod a hole, or a lower pitch prop. Check the rpm against the 5,000 to 6,000 range.

Warning light comes on

Low oil pressure warning means stop and check the oil. Overheat usually means cooling water is blocked. Do not keep running and hope.

How it compares with neighbouring models

We stock the whole small Suzuki range, so it is easy to compare. Here is how the Suzuki DF25AES2 for sale sits against its neighbours:

• Suzuki DF25AS2: the same short shaft tiller motor with manual start only. Cheaper and a little lighter. Good if you do not mind pulling.
• Suzuki DF25ATHS2: short shaft tiller with electric start and power trim and tilt. Worth it if you beach a lot or lift the motor often.
• Suzuki DF20AES2: 20 HP twin, lighter and cheaper. Fine for small boats, but the 25 has more punch with a load.
• Suzuki DF30ATHL2: same body size, 30 HP, long shaft with power tilt. If your boat is rated for 30, it is the next step up.
• Suzuki DF25AES5: the 5 series version of the same configuration.

Honest advice: if you plan to lift the motor every time you come into shallow water, pay the extra for power tilt. Otherwise the Suzuki DF25AES2 for sale is the sweet spot of price and convenience. You can also browse the full 25 HP Suzuki range to see every shaft and colour option side by side.

Suzuki DF25AES2 for sale: FAQ

Can I start the Suzuki DF25AES2 for sale without a battery?

Yes. It has a recoil starter as backup and the EFI does not need a battery to run. You just cannot use the electric starter without one.

Is the Suzuki DF25AES2 for sale really new?

Yes. New, in the Suzuki crate, never mounted. We do not sell used motors as new.

Does it charge the battery?

Yes, through a 12V 14A charging system. Enough for the starter, a fish finder and navigation lights.

Can I add power trim later?

Not practically. Power trim and tilt is a different bracket assembly. If you think you will want it, buy the ATHS2 version from the start.

What fuel does it need?

Regular unleaded at 87 octane (91 RON) or better. Avoid fuel with high ethanol content and do not leave fuel sitting for months.

How long does delivery take?

It depends on the destination and the shipping method. We give you a time estimate with the shipping quote, before you pay.

Do you sell other Suzuki models?

Yes. See the full Suzuki outboard range or the whole shop. Suzuki’s own line up is on the Suzuki Marine outboards page if you want to compare.
