Suzuki DF175APX2 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 DF175A page on Suzuki Marine if you want to compare models side by side.

What the Model Code on the Suzuki DF175APX2 for sale Means

Suzuki model codes look confusing until someone explains them once. DF is Suzuki’s four stroke prefix and 175 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. That is a big part of why people choose the Suzuki DF175APX2 for sale.

The Big Block Behind the Suzuki DF175APX2 for sale

The DF175AP uses the same 2.9 litre inline four as Suzuki’s 200. A big engine tuned to 175 horsepower has torque to spare and does not have to strain, which is good news for fuel use and engine life.

The AP models add Suzuki Precision Control drive by wire and Suzuki Selective Rotation. That means smooth electronic shifts, an exact throttle and a motor that can be set for standard or counter rotation at rigging time.

Lean Burn control, an offset driveshaft and a two stage gear reduction round out the package. The 2.50:1 final ratio lets it turn a good sized prop on heavier boats. Owners of the Suzuki DF175APX2 for sale tell us the same thing again and again.

Selective Rotation

On the Suzuki DF175APX2 for sale, prop direction is set electronically. One motor can be standard or counter rotation, so twin rigs use two of the same model with a right hand and a left hand prop.

Boats That Suit the Suzuki DF175APX2 for sale

Centre consoles from 19 to 23 feet

A single 175 is a popular choice at this size.

Bay boats

Strong torque for loaded bay boats and good economy.

Pontoons and tritoons

Tritoons rated around 175 run well on this motor.

Twin rigs on bigger boats

Twin 175s with Selective Rotation are a simple, strong setup for boats in the mid 20 foot range.

How the Suzuki DF175APX2 for sale Feels on the Water

At the dock the Suzuki DF175APX2 for sale is smooth and quiet, and the electronic shift goes into gear softly.

The big displacement means strong pull from low revs. Boats get on plane quickly and cruise without the motor sounding busy.

Single or Twin Installs

On a single engine boat, set the Suzuki DF175APX2 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. It is one of the reasons we keep the Suzuki DF175APX2 for sale in stock.

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 DF175APX2 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. You get all of that with the Suzuki DF175APX2 for sale.

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 DF175APX2 for sale or the DF175AT?

The DF175AT uses the same engine with mechanical controls and fixed rotation. It suits boats with existing cable controls.

The Suzuki DF175APX2 for sale adds drive by wire and Selective Rotation, which make it the better choice for twin rigs and digital helms.

Who Buys the Suzuki DF175APX2 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 DF175APX2 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.

The First Ten Hours

New motors need a gentle start. For the first hour keep the Suzuki DF175APX2 for sale below half throttle and keep changing speed. After that you can use more throttle in short bursts. Avoid long runs at wide open throttle until the break-in period in the manual is done.

Book the first service on time. Fresh engine oil, a new filter and fresh gear oil set the motor up for the long run. Ask us if you want photos of the Suzuki DF175APX2 for sale before it ships.

Keeping the Suzuki DF175APX2 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.

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 175 HP, ask us and we will point you to a better match. We are happy to answer questions about the Suzuki DF175APX2 for sale by email or chat.

What It Costs to Run

A big block running at 175 with Lean Burn control is economical at cruise. We do not invent burn numbers.

Servicing is not expensive either. Suzuki parts are widely stocked, and most routine jobs on the Suzuki DF175APX2 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. The Suzuki DF175APX2 for sale handles this well.

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

Choosing a Propeller for the Suzuki DF175APX2 for sale

The right prop lets the motor reach its full throttle range of 5,500 to 6,100 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 29 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. This is where the Suzuki DF175APX2 for sale earns its keep.

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.

Instruments for the Suzuki DF175APX2 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. Plenty of buyers send us their boat details before ordering the Suzuki DF175APX2 for sale, and we like that.

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.

Running in Tropical or Cold Water

Tropical boaters should check the impeller more often and keep an eye on the cooling stream, because warm water with sand or silt wears pumps faster. In cold regions the Suzuki DF175APX2 for sale starts easily with its fuel injection, but always store it upright and drained before freezing weather.

Trailering and Launching

If the boat lives on a trailer, tilt the motor up for the road and fit a transom saver or motor support so the bumps are not taken by the tilt system. Check the skeg clears the road on steep driveways. At the ramp, lower the motor fully before you start it, and never run it out of the water. A quick look at the cooling stream once it is running costs nothing and saves a lot. Keep that in mind when you set up the Suzuki DF175APX2 for sale.

After a salt launch, rinse the trailer and the motor together and run the flush. It takes ten minutes and adds years.

Storage Between Trips

After the last run of the day, flush the motor and let it drain in the down position, then tilt it up. If it will sit for weeks, disconnect the battery or put it on a maintainer. For long storage, stabilise the fuel, change the oil, grease the steering and tilt points and fit a cover. That applies to the Suzuki DF175APX2 for sale as much as any motor.

Common Problems and Quick Checks

Will not crank. Check the kill switch lanyard is clipped on, the lever is in neutral and the battery terminals are clean and tight.

Cranks but will not start. Squeeze the primer bulb until it is firm, open the tank vent and drain any water from the separator bowl. If you are unsure, send us a photo of the transom and we will check the Suzuki DF175APX2 for sale is the right fit.

Weak tell-tale stream. Clear the outlet with a bit of wire. If it is still weak, have the impeller checked before running hard.

Will not reach full revs. Usually the wrong prop or the motor mounted too low. Check the prop first.

Warning buzzer. Slow down straight away, check the cooling stream and oil, and do not keep running with an alarm.

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.

Repowering an Older Boat

If you are swapping out an old motor, check the transom core around the bolt holes once it is off. Soft or wet wood has to be fixed before you hang a new engine on it. Look at the steering too. Weeping hydraulic rams and stiff cables should be replaced now, not after the first trip.

On the first run, watch the tell-tale, listen for anything odd and see how the boat sits. Adjust trim and mounting height until it runs level and the prop holds in turns.

Coming From an Old Two Stroke

A lot of our buyers are replacing a two stroke that has done its time. The difference is bigger than most expect. No oil to mix or top up, no blue smoke at the dock, far less noise and a big drop in fuel use at cruise. The four stroke is heavier than an old two stroke of the same power, so check the capacity plate and how the boat sits once it is fitted. Most owners find the trade is well worth it after the first few trips.

Expect a different sound too. A four stroke is quieter and smoother, and some people keep looking back to check it is still running.

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.

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.
