SUZUKI 90 HP DF90ATX2 OUTBOARD MOTOR

Description

We have the Suzuki DF90ATX2 for sale new in the factory crate. It is Suzuki’s 90 horsepower inline 4 four stroke with a 25 inch shaft, power trim and tilt, electric start and remote steering, finished in Pearl Nebular Black. It is a favourite on pontoons, aluminium fishing boats and small runabouts.

We sell new outboards to private owners, fishing operators, boat builders and dealers, and we ship worldwide. Tell us where your boat is and we send you a delivery quote before you commit to anything. This is where the Suzuki DF90ATX2 for sale earns its keep.

Below you will find the full specs, what the model code means, the boats it suits, rigging, maintenance and the questions buyers ask us most. It is a long page on purpose. A motor like this is a serious purchase and most people want the details first.

Suzuki DF90ATX2 for sale: Specifications

Numbers can move a little between production runs, so the paperwork in the crate is the final word. Suzuki keeps the current figures on its DF90A page on Suzuki Marine if you want to compare models side by side.

What the Model Code on the Suzuki DF90ATX2 for sale Means

Suzuki model codes look confusing until someone explains them once. DF is Suzuki’s four stroke prefix and 90 is the horsepower. The A marks the A generation of this engine. T means power trim and tilt. X is an extra long shaft, for a 25 inch transom. The 2 at the end is the series number in Suzuki’s order code.

What you do not see in the code matters too: there is no Z, so it is standard rotation, and there is no W, so the cowl is black.

What Is Inside the Suzuki DF90ATX2 for sale

The DF90A uses a 1.5 litre inline four with dual overhead cams and 16 valves. Multi-point sequential fuel injection feeds each cylinder on its own, and Lean Burn control trims the fuel at cruise.

Suzuki gave it a 2.59:1 gear ratio, which is low for a 90. That lets the motor turn a bigger prop, and a bigger prop moves heavier boats and pontoons with less fuss. Plenty of buyers send us their boat details before ordering the Suzuki DF90ATX2 for sale, and we like that.

The timing chain is self-adjusting and runs in oil, so there is no cam belt to replace. Troll Mode is an option, letting you set trolling speed in small steps with a switch.

Troll Mode

With the optional Suzuki Troll Mode System you can set trolling speed in small steps with a switch, without touching the throttle. Anglers who troll a lot love it.

Boats That Suit the Suzuki DF90ATX2 for sale

Pontoons

Pontoons from 18 to 22 feet rated for 90 HP.

Aluminium fishing boats

Deep V boats from 16 to 18 feet.

Bay boats and skiffs

Light inshore boats.

Family runabouts

Small bowriders and runabouts.

How the Suzuki DF90ATX2 for sale Feels on the Water

The Suzuki DF90ATX2 for sale is smooth and quiet at idle. Most people are surprised how little vibration comes through the boat.

It gets boats up on plane cleanly and cruises at a relaxed rpm. Keep that in mind when you set up the Suzuki DF90ATX2 for sale.

Single or Twin Installs

A motor in this size class is nearly always run as a single engine, and the Suzuki DF90ATX2 for sale is standard rotation, which is what a single engine boat needs. On a catamaran or a wide work boat some owners run two side by side. If that is your plan, tell us before ordering and we will help with the setup.

Colour and Finish

Black is the standard Suzuki finish and suits almost any boat. If you want a white cowl to match a white hull, ask us about the W version of this motor. The engine underneath is the same.

Rigging the Suzuki DF90ATX2 for sale

This is a remote model. You will need a control box with throttle and shift cables, a steering system rated for 90 HP, a key switch and harness, gauges, a good marine battery and a fuel system with a water separating filter.

Mount the motor so the anti-ventilation plate sits roughly level with the bottom of the hull, then fine tune after a test run. If the prop blows out in turns, drop it a hole. If there is a lot of spray and drag, raise it. The 12 V, 27 amp alternator keeps electronics charged on a normal day.

Transom Height and Shaft Length

The 25 inch shaft suits most offshore boats and centre consoles. Measure from the top of the transom to the bottom of the hull at the centreline before you order. Around 25 inches means the X shaft is right. Boats on an outboard bracket or with a deep notch may need a different length, so measure carefully. That applies to the Suzuki DF90ATX2 for sale as much as any motor.

Suzuki DF90ATX2 for sale or a 115?

A 115 adds power and weight, about 60 pounds more. It makes sense on boats rated for 115 that carry heavy loads.

The Suzuki DF90ATX2 for sale is lighter, cheaper to run and plenty for most boats rated at 90.

The People Who Order This Motor

We sell the Suzuki DF90ATX2 for sale to weekend boaters, full time fishermen, charter skippers and boat builders all over the world. What they have in common is that they want a new Suzuki with proper paperwork, delivered to their door at a clear price. That is what we do.

Day to Day Ownership

Good outboards fade into the background. You stop thinking about the engine and think about the fishing or the family instead. The Suzuki DF90ATX2 for sale starts on the first turn, idles cleanly with no choke and does not foul plugs after a slow morning. Keep up with flushing and servicing and it will keep doing that for years.

Breaking In the Suzuki DF90ATX2 for sale

Follow the break-in in the owner’s manual. In short: vary the revs during the first hours, do not hold it at full throttle for long, and change the engine oil and filter at the first service. A motor broken in gently uses less oil and runs smoother for the rest of its life.

Give the gearcase its first oil change at that service too. It flushes out the fine metal from new gears bedding in.

Keeping the Suzuki DF90ATX2 for sale Healthy

Nothing about this motor needs special tools for routine care. Stick to a simple routine:

• After every trip: flush, rinse and check the tell-tale stream.
• Every month in use: look at the anodes, the prop and the fuel filter bowl.
• Every 100 hours or yearly: engine oil, oil filter, gear oil and a grease of every fitting.
• Every two years or so: water pump impeller and thermostat check.
• At the major service: plugs, fuel filter and a valve clearance check if the manual calls for it.

The timing chain runs in oil and does not need replacing like a belt. That is one less big bill to plan for.

Matching the Motor to the Boat

The right motor is the one your boat is rated for, carrying the load you normally carry. Check the capacity plate for maximum horsepower and engine weight, then think about how you use the boat. Heavy loads, rough water and long runs all favour running close to the maximum rating. Light boats and calm water give you more freedom. If the numbers do not line up with 90 HP, ask us and we will point you to a better match. If you are unsure, send us a photo of the transom and we will check the Suzuki DF90ATX2 for sale is the right fit.

Fuel Use and Running Costs

Lean Burn makes the Suzuki DF90ATX2 for sale one of the more economical 90s. Real burn depends on your boat.

Parts are easy to find in most countries because Suzuki sells a lot of outboards. Filters, impellers, anodes and plugs are normal stock items. That keeps the long term cost of owning the Suzuki DF90ATX2 for sale sensible.

Keep the Fuel Clean

Most problems people blame on the engine start in the tank. Water, old fuel and dirt in the lines will make any motor run badly. Change the water separating filter every season, drain the bowl if you see water and use fresh fuel. In hot, humid places keep the tank as full as you can when the boat is parked, so there is less room for condensation.

Treat the fuel well and fuel injection rewards you with easy starts and smooth running.

Getting the Prop Right

A motor is only as good as its prop. With the Suzuki DF90ATX2 for sale you want to land in the 5,300 to 6,300 rpm band at wide open throttle with a normal load. Too many revs means the pitch is too low. Too few means it is too high. The usual pitch choice for this motor is a 13 to 23 inch pitch range.

Look at Suzuki genuine parts and accessories for propellers and service parts, or ask us. We are happy to suggest a pitch if you send the boat make, length and typical load. Many repeat customers come back for a second Suzuki DF90ATX2 for sale on another boat.

Low Speed and Trolling

Four strokes are much better at low speed than old two strokes. They idle cleanly, do not load up with oil and do not foul plugs after an hour of trolling. If you troll a lot, ask about Suzuki Troll Mode, which lets you set trolling speed in small steps with a switch. Drift socks and a trolling plate are also cheap ways to slow a boat down further.

Instruments for the Suzuki DF90ATX2 for sale

Suzuki’s digital gauges read engine data straight from the motor, including fuel flow and service reminders. If you prefer, plain analogue tach and trim gauges work too. Whatever you fit, run tidy wiring with proper fuses. Good wiring now saves a lot of headaches later.

Getting the Electrics Right

A strong battery and clean connections are half the battle. Choose a marine cranking battery that meets or beats the motor’s requirement, crimp and heat shrink every connection and keep the battery secured in a box. A battery switch and a second battery for the electronics make long days much less stressful.

Salt Water Care

Flush after every salt trip. Rinse the outside, wipe salt off the cowl and spray a corrosion inhibitor under the cowl now and then. Suzuki’s anti-corrosion finish is tough, but salt finds any gap if you ignore it. If the boat lives in the water, tilt the motor up when you leave it. The Suzuki DF90ATX2 for sale is covered here too.

Hot and Cold Climates

In hot climates, check the tell-tale stream often and keep the cooling passages clean. Warm, silty water is hard on impellers. In cold climates, fuel injection makes starting easy, but drain the motor and winterise it properly before a freeze.

Towing and Ramp Habits

Long road trips are harder on an outboard than most people think. Use a motor support bracket rather than resting the motor on the tilt ram, and check the bolts on the transom clamp or mounting after the first few trips. At the ramp, back in, lower the motor, start it in the water and watch for the tell-tale before you drive off the trailer.

Back home, flush it while you wash the boat. Same routine every time and it becomes second nature. That is a big part of why people choose the Suzuki DF90ATX2 for sale.

Laying It Up

For short breaks, flush, drain and tilt up. For a long lay up, run stabilised fuel through the system, change the engine and gear oil, fog the engine if the manual calls for it, grease every fitting and keep the battery charged. A cover keeps sun and bird mess off the cowl.

Simple Fixes Before You Call a Mechanic

No crank: lanyard clipped on, lever in neutral, battery charged, terminals tight.

Hard starting: firm primer bulb, tank vent open, no water in the separator, fresh fuel. Owners of the Suzuki DF90ATX2 for sale tell us the same thing again and again.

Overheat alarm: stop, tilt up and look for a plastic bag or weed over the intake. Check the tell-tale stream when you restart.

Low top speed: check the prop for damage, check the mounting height and make sure the boat bottom is clean.

Rough running: old fuel and dirty filters cause most of it. Start there. It is one of the reasons we keep the Suzuki DF90ATX2 for sale in stock.

Carry These on Board

A spare kill cord, a spare prop with nut and washer, a fuel filter, a couple of spanners, a radio and a torch. Add a tow line and an anchor that holds. It sounds basic, but most bad days on the water start with something small.

Tips for a Repower

A repower is the best chance you will get to fix the things you cannot reach with a motor on the back. Check the transom, replace old fuel hoses and the primer bulb, clean or replace the tank pickup and fit a new water separating filter. Fresh fuel lines and clean fuel make a new motor happy from the first day.

Measure the transom height before ordering so the shaft length is right. It is the one mistake that is hard to fix later. You get all of that with the Suzuki DF90ATX2 for sale.

Two Stroke to Four Stroke: What Changes

If your old motor was a two stroke, a few things will feel new. You will stop buying two stroke oil. The motor will idle cleanly without smoke. Fuel bills drop, often a lot, especially at cruise. You will also notice the extra weight on the transom, so set the trim and mounting height carefully on the first runs.

Service changes too. Instead of plugs and oil injection checks, you will be changing engine oil and filters like a car. It is simple, and most owners prefer it.

Avoid These Common Errors

Ordering the wrong shaft length, guessing the prop, reusing worn out controls and going over the boat’s power or weight rating. Those four mistakes cause most of the post purchase headaches we hear about. All of them are avoided with a tape measure, a look at the capacity plate and a short chat with us before you pay. Ask us if you want photos of the Suzuki DF90ATX2 for sale before it ships.

The First Year of Ownership

Year one is easy. Follow the break-in, get the first service done on time and keep a log of hours. Look at the prop and anodes now and then, and flush after every salt trip. Before winter or a long break, do a proper lay up. If you do those simple things, the motor will reward you with years of trouble free running.
