SUZUKI 150 HP DF150APX2 OUTBOARD MOTOR

Description

We have the Suzuki DF150APX2 for sale new in the factory crate. It is Suzuki’s 150 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 strong fit for centre consoles, bay boats and bigger pontoons that need real torque without V6 weight.

This is a new motor in the factory crate, sold by us and shipped to your country. Before you pay for freight you get a written delivery quote, so there are no surprises later. This is where the Suzuki DF150APX2 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 DF150APX2 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 DF150A page on Suzuki Marine if you want to compare models side by side.

What the Model Code on the Suzuki DF150APX2 for sale Means

Suzuki model codes look confusing until someone explains them once. DF is Suzuki’s four stroke prefix and 150 is the horsepower. The A marks the A generation of this engine. The P stands for Suzuki Precision Control, the drive by wire system, and on this engine it comes with Selective Rotation. 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 W, so the cowl is black. Plenty of buyers send us their boat details before ordering the Suzuki DF150APX2 for sale, and we like that.

A Big Block 150: The Suzuki DF150APX2 for sale

Most 150s use an engine of around 2.0 to 2.5 litres. Suzuki’s uses the same 2.9 litre inline four as its 200. That gives the DF150AP more torque than most rivals and lets it run a relaxed cruise.

The AP models carry Suzuki Precision Control drive by wire and Suzuki Selective Rotation. Shifts are smooth and quiet, the throttle is exact, and the same motor can run standard or counter rotation.

Lean Burn control keeps cruising economy good, and the two stage gear reduction gives a 2.50:1 ratio that suits bigger props on heavier boats. Keep that in mind when you set up the Suzuki DF150APX2 for sale.

Selective Rotation

Prop direction on the Suzuki DF150APX2 for sale is set electronically at rigging. One model covers both sides of a twin rig.

Boats That Suit the Suzuki DF150APX2 for sale

Centre consoles from 18 to 21 feet

A single 150 is a common pick on these boats.

Bay boats

Good torque for a loaded bay boat.

Pontoons

Larger pontoons and tritoons rated for 150 run very well.

Twin rigs

Twin 150s with Selective Rotation are a neat setup on 22 to 25 foot boats.

How the Suzuki DF150APX2 for sale Feels on the Water

The Suzuki DF150APX2 for sale feels unhurried. Electronic shifting is soft and the motor idles smoothly.

Torque from the big block gets loaded boats on plane cleanly, and cruise feels effortless.

Single or Twin Installs

On a single engine boat, set the Suzuki DF150APX2 for sale to standard rotation and fit a right hand prop. For twins, order two of the same model, set one to counter rotation at rigging time and fit a left hand prop on that side. There is no separate Z model to hunt for.

Tell us when you order a pair and we will match the two motors so serial numbers and paperwork line up. That applies to the Suzuki DF150APX2 for sale as much as any motor.

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 DF150APX2 for sale

This is a drive by wire motor, so there are no throttle or shift cables. You will need Suzuki digital remote controls, the engine and helm harnesses, a compatible gauge, a steering system rated for the horsepower (hydraulic is normal at this size), 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, 44 amp alternator keeps electronics charged on a normal day. If you are unsure, send us a photo of the transom and we will check the Suzuki DF150APX2 for sale is the right fit.

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.

Suzuki DF150APX2 for sale or the DF150AT?

The DF150AT uses the same engine with mechanical controls and fixed rotation.

The Suzuki DF150APX2 for sale is for boats with digital helms or twin rigs where Selective Rotation and drive by wire make life easier.

Who Buys the Suzuki DF150APX2 for sale From Us

Most of our buyers are owners who want a reliable motor and a fair price without dealer games. Next come fishing and charter operators repowering a working boat, and then boat builders and dealers who need stock to rig new hulls. The feedback after a season is nearly always the same: it starts every time, it is easy on fuel compared with what they had, and it has needed nothing beyond normal servicing.

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 DF150APX2 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 DF150APX2 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. Many repeat customers come back for a second Suzuki DF150APX2 for sale on another boat.

Keeping the Suzuki DF150APX2 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 filters and a check of the trim system.

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

Is 150 Horsepower Right for Your Boat?

Start with the capacity plate on your boat. It gives the maximum horsepower and the maximum weight the transom is built for. Most owners do well with a motor at or near the maximum rating, because a motor that is not working flat out lasts longer and uses less fuel at cruise. If your boat is rated well below 150 HP, do not go over the plate. If you are unsure, send us the make, model and length and we will check it for you. The Suzuki DF150APX2 for sale is covered here too.

What It Costs to Run

A 2.9 litre engine at 150 horsepower with Lean Burn is efficient at cruise. Your hull decides the real numbers.

Servicing is not expensive either. Suzuki parts are widely stocked, and most routine jobs on the Suzuki DF150APX2 for sale can be done by any decent marine mechanic or by a handy owner.

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. That is a big part of why people choose the Suzuki DF150APX2 for sale.

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

Choosing a Propeller for the Suzuki DF150APX2 for sale

The right prop lets the motor reach its full throttle range of 5,000 to 6,000 rpm with your normal load aboard. If it over revs, go up in pitch. If it cannot get into the range, come down. Suzuki lists a 17 to 19 inch pitch range for this motor.

Suzuki’s own props are a good match, and the Suzuki genuine parts and accessories range also covers filters, anodes and service kits. Or tell us your boat and load and we will suggest a starting prop. Owners of the Suzuki DF150APX2 for sale tell us the same thing again and again.

Running Slow All Day

Anglers spend a lot of time at idle or just above it. A fuel injected four stroke handles that well. There is no smoke, no oil fouling and no hard restart after a long drift. Keep an eye on the battery if you run a lot of electronics at low revs, and give the motor a short run at higher revs on the way home to clear it out.

Gauges and Electronics

You can run simple analogue gauges or Suzuki’s multi-function digital gauges, which show rpm, trim, fuel flow, hours and warnings on one screen. Many owners also network the motor into their chartplotter. Keep engine wiring separate from accessory wiring, fuse everything and use marine grade connectors. It is one of the reasons we keep the Suzuki DF150APX2 for sale in stock.

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.

Looking After It in Salt Water

Fresh water flushing after every trip is the most important habit you can have. Use the flush port with a garden hose, rinse the outside and check the anodes regularly. On a mooring, keep the motor tilted up between trips so the gearcase is not sitting in the water. You get all of that with the Suzuki DF150APX2 for sale.

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. Ask us if you want photos of the Suzuki DF150APX2 for sale before it ships.

Back home, flush it while you wash the boat. Same routine every time and it becomes second nature.

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. We are happy to answer questions about the Suzuki DF150APX2 for sale by email or chat.

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. The Suzuki DF150APX2 for sale handles this well.

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.

Safety Gear Worth Carrying

Clip the kill switch lanyard on every time you run. Carry a spare lanyard, a basic tool kit, a spare prop and prop nut, a spare fuel filter, a VHF radio and a way to call for help. None of it costs much, and any of it can save a day on the water.

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.

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.

Mistakes We See Buyers Make

The most common one is the wrong shaft length. Measure the transom before ordering, not after the crate arrives. The second is under-propping, which lets the motor over rev and wastes fuel. The third is skipping the rigging list, then finding out the old controls or harness do not fit the new motor. And the last is ignoring the boat’s capacity plate. A motor heavier or more powerful than the hull is rated for is a real safety problem.

What a Typical First Season Looks Like

Most owners do the break-in over the first few weekends, then the first service. After that it is simply using the boat: run it, flush it, tilt it up. Around the middle of the season it is worth checking the anodes and the prop for dings. At the end of the season comes the lay up service with oil, gear oil and a grease. That is honestly all most people need to do in year one.
