Suzuki 300 HP DF300APXX2 Outboard Motor

Description

We have the Suzuki DF300APXX2 for sale new in the factory crate. It is Suzuki’s 300 horsepower V6 four stroke with a 30 inch shaft, power trim and tilt, electric start and remote steering, finished in Pearl Nebular Black. If you run an offshore centre console, a big bay boat or a heavy cabin boat, this is the class of motor most owners end up choosing.

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. Ask us if you want photos of the Suzuki DF300APXX2 for sale before it ships.

We put everything on this one page: specifications, the model code, boats it suits, how it runs, rigging, care, shipping and an FAQ at the end. Read what you need and skip the rest.

Suzuki DF300APXX2 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 DF300AP page on Suzuki Marine if you want to compare models side by side.

What the Model Code on the Suzuki DF300APXX2 for sale Means

Suzuki model codes look confusing until someone explains them once. DF is Suzuki’s four stroke prefix and 300 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. XX is the ultra long shaft, for a 30 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. We are happy to answer questions about the Suzuki DF300APXX2 for sale by email or chat.

What Sets the Suzuki DF300APXX2 for sale Apart

The DF300AP has been Suzuki’s flagship single prop V6 for years. The block is a 4.0 litre V6 with an offset driveshaft, which puts the crankshaft ahead of the driveshaft and moves weight forward. That keeps the motor compact on the transom and helps it run smoother.

The headline feature is Suzuki Selective Rotation. The same lower unit can run standard or counter rotation. You choose the direction when the motor is rigged, with a simple setting rather than a different gearcase. For twin rigs that means you do not need to hunt for a matched left hand motor, and if you ever need a spare, one motor covers both sides.

Suzuki also cools the fuel before it goes into the engine. Cooler fuel is denser, which helps power and economy. Add Lean Burn control and a two-way water inlet that keeps cooling water flowing in shallow or weedy spots, and you have a motor that is easy to live with day after day. The Suzuki DF300APXX2 for sale handles this well.

Suzuki Selective Rotation, Explained

On the Suzuki DF300APXX2 for sale the propeller direction is selected electronically when the motor is set up. Run it standard rotation on a single engine boat, or set one motor to counter rotation for a twin rig so the props turn in opposite directions and the boat tracks straight. You still need the right hand or left hand propeller to match, but the motor itself is the same. It is one of the most practical ideas Suzuki has had.

Drive by Wire Controls

The Suzuki DF300APXX2 for sale uses Suzuki Precision Control, a fly by wire system. The helm talks to the motor electronically, so shifts are silky and the throttle is exact. You will need Suzuki digital controls, harnesses and a compatible gauge. We can quote a full rigging package with the motor.

Boats That Suit the Suzuki DF300APXX2 for sale

Offshore centre consoles from 25 to 35 feet

A single DF300AP suits many 25 to 27 foot boats. Twins are the common choice from about 28 to 35 feet.

Walkarounds and cabin boats

Heavier hulls with a cabin, a head and a lot of tackle need torque at cruise. The Suzuki DF300APXX2 for sale gives that without strain.

Bay boats and big flats boats

On the L shaft version, high performance bay boats get strong holeshot and a good top end.

Charter and work boats

Long hours are normal for charter skippers, and the 4.0 litre block is built for that kind of duty.

How the Suzuki DF300APXX2 for sale Feels on the Water

Drive by wire shifting makes the Suzuki DF300APXX2 for sale feel smooth and calm at the dock. The throttle is precise, so slow manoeuvres in a crowded marina are easy.

Out of the hole it pulls hard, and once the boat is on plane it settles into a steady cruise with plenty left in reserve. Owners often say the motor feels like it is loafing at speeds where older engines were working hard.

Single or Twin Installs

On a single engine boat, set the Suzuki DF300APXX2 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. This is where the Suzuki DF300APXX2 for sale earns its keep.

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 DF300APXX2 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, 54 amp alternator keeps electronics charged on a normal day. Plenty of buyers send us their boat details before ordering the Suzuki DF300APXX2 for sale, and we like that.

Transom Height and Shaft Length

The 30 inch ultra long shaft is for big offshore boats with tall transoms or setback brackets. It keeps the prop deep in the water when the stern lifts in a sea. Measure from the top of the transom or bracket to the bottom of the hull before ordering. If you measure close to 25 inches, you want the X shaft instead.

Suzuki DF300APXX2 for sale or the DF350A?

If your boat is rated for 300 and runs well with a single prop, the Suzuki DF300APXX2 for sale is usually the better buy. It is lighter than the DF350A, easier to prop, and Selective Rotation keeps twin rigs simple.

The DF350A only pulls ahead on very heavy boats or rigs of three and four motors where the dual prop grip pays off. For everything else, the 300 is the sweet spot. Keep that in mind when you set up the Suzuki DF300APXX2 for sale.

Who Buys the Suzuki DF300APXX2 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.

Living With the Suzuki DF300APXX2 for sale

Owning this motor is mostly uneventful, and that is the point. Turn the key and it starts. Run your day, flush it, tilt it up and go home. With fuel injection there is no carburettor to gum up if the boat sits for a few weeks, and it behaves the same on a cold morning as on a hot afternoon.

The First Ten Hours

New motors need a gentle start. For the first hour keep the Suzuki DF300APXX2 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.

Maintenance on the Suzuki DF300APXX2 for sale

Servicing a Suzuki V6 is straightforward. Most owners handle the basics and let a mechanic do the bigger jobs.

• Flush with fresh water after every trip in salt or muddy water.
• Change engine oil and filter at the hours in the manual, or once a year.
• Change the gear oil every season. Milky oil means water is getting in.
• Replace anodes when they are about half gone.
• Replace the water pump impeller every couple of seasons, sooner in sandy water.
• Change the fuel filters and keep fuel fresh if the boat sits.
• Check plugs, the trim fluid and the thermostats at the service intervals.

The motor warns you about overheating and low oil pressure, and Suzuki fits an over-rev limiter. Treat it well and it will put in many thousands of hours. That applies to the Suzuki DF300APXX2 for sale as much as any motor.

Is 300 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 300 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.

Fuel Use and Running Costs

Lean Burn control, fuel cooling and the 2.08:1 gearing help the Suzuki DF300APXX2 for sale cruise efficiently. We do not invent burn figures because hull, load and props change everything.

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 DF300APXX2 for sale sensible.

Fuel Quality Matters

Modern fuel injected motors are very reliable, but they do not like bad fuel. Buy from busy fuel stations, keep the tank vent clean and fit a good water separating filter between the tank and the motor. If your fuel contains ethanol, do not let it sit for months. Ethanol pulls in water, and water in fuel is the most common cause of rough running we hear about. If you are unsure, send us a photo of the transom and we will check the Suzuki DF300APXX2 for sale is the right fit.

A fuel stabiliser in the tank before a lay up is cheap insurance.

Getting the Prop Right

A motor is only as good as its prop. With the Suzuki DF300APXX2 for sale you want to land in the 5,700 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 17 to 27.5 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 DF300APXX2 for sale on another boat.

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. The Suzuki DF300APXX2 for sale is covered here too.

Batteries and Wiring

Use a marine starting battery with good cranking amps, keep the terminals clean and tight and fit a battery switch. If you run lots of electronics, a second house battery with a charging relay keeps the starting battery fresh. Corrosion on terminals and loose earth wires cause more no-start calls than anything inside the engine.

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. That is a big part of why people choose the Suzuki DF300APXX2 for sale.

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 DF300APXX2 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.

After a salt launch, rinse the trailer and the motor together and run the flush. It takes ten minutes and adds years. Owners of the Suzuki DF300APXX2 for sale tell us the same thing again and again.

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.

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. It is one of the reasons we keep the Suzuki DF300APXX2 for sale in stock.

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.

Weak tell-tale stream. Clear the outlet with a bit of wire. If it is still weak, have the impeller checked before running hard. You get all of that with the Suzuki DF300APXX2 for sale.

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.

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.

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.

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.
