SUZUKI 50 HP DF50ATL2 OUTBOARD MOTOR

Description

We have the Suzuki DF50ATL2 for sale new in the factory crate: a 50 HP, three cylinder, fuel injected four stroke with a 20 inch long shaft, remote controls, electric start and power trim and tilt. The price is on this page, and we ship it to customers worldwide with a delivery quote sent before any payment.

Of all the small Suzukis we sell, this is the one we recommend most often. It weighs the same as the 40 but makes 10 more horsepower, and on a typical 16 to 18 foot boat that extra punch is easy to feel.

If those lines already match your boat, the Suzuki DF50ATL2 for sale is probably the motor you want. The rest of this page fills in the detail.

Is 50 HP the right size for your boat?

The question we hear most is whether to buy the 40 or the 50. They share the same block, the same weight and the same lower unit, so the 50 does not cost you anything in transom load. It costs a little more to buy and a touch more fuel at full throttle. At cruise, the difference is small.

Here is how we usually advise:

• If your boat’s capacity plate allows 50 HP or more, buy the Suzuki DF50ATL2 for sale. People rarely regret more power on the same weight.
• If the plate says 40 HP max, buy the 40. Do not overpower a hull.
• If you carry four people and gear regularly, the 50 gets you on plane faster and holds speed in a chop.
• If you mostly troll and putter, a 40 will do the job, but the 50 still gives you reserve for the run home.

Typical boats we ship the Suzuki DF50ATL2 for sale for include 16 to 19 foot aluminum center consoles, small fiberglass bay boats, bass style hulls rated for 50, dive boats in sheltered water and lighter pontoons. For heavy pontoons, look at the DF50AV high thrust version further down.

A normal day with this motor

Picture a 17 foot aluminum center console with two anglers, a full tank, a cooler and rods. You turn the key, the Suzuki DF50ATL2 for sale fires and settles into a quiet idle within a second or two. You idle out of the marina without the motor shaking the boat.

Out of the no wake zone you push the throttle and the boat climbs onto plane quickly, with less bow rise than an older 40 would give you. Trim out a little and it settles into a cruise at around mid throttle. You can talk without shouting. At the fishing spot, drop to idle or Troll Mode if fitted.

At the end of the day you run home into a chop and the extra 10 HP over a 40 is what keeps the speed up. That is the main reason we push people towards the 50 when the boat allows it.

The model code, letter by letter

Every letter in the name tells you something. For the Suzuki DF50ATL2 for sale:

There is no W, so the cowl is Suzuki’s standard Pearl Nebular Black. The light grey version is the Suzuki DF50ATLW2. There is no V either, so this has the standard gear ratio rather than the high thrust pontoon gearcase.

What makes this motor good to own

A big block for a 50

Nine hundred and forty one cc is generous for 50 HP. The Suzuki DF50ATL2 for sale makes its power without screaming. At a normal cruise it sits in the middle of the rev range, which is quieter and easier on parts.

Lean Burn Control

Suzuki’s ECU leans out the fuel mixture when load is light and conditions allow. On long steady runs this saves fuel. It works on its own, you do not switch anything on.

Chain driven camshafts

Two overhead cams driven by a chain in an oil bath. On the Suzuki DF50ATL2 for sale there is no timing belt to inspect or replace, which removes one of the more costly jobs from a typical outboard service history.

Troll Mode option

With the Suzuki Troll Mode switch or a compatible gauge you can step idle speed up and down in small increments. Anglers who troll for hours like it a lot. It is an add on, and we can include it on the quote.

Easy Start

One turn of the key and the motor cranks until it fires. Simple, and it stops people from grinding starters.

Built in protection

Over rev limiter, low oil pressure caution, overheat warning. If something is wrong, the Suzuki DF50ATL2 for sale will reduce rpm and warn you before damage happens. There is also a flush port for fresh water rinsing.

Fuel use, honestly

We do not quote a single fuel figure for the Suzuki DF50ATL2 for sale, because hull, load and the way you drive change it a lot. What we can tell you is how it behaves compared with older motors.

Against a carbureted two stroke 50, the difference is large at cruise and at idle. Against an older carbureted four stroke, the EFI and lean burn still give a clear saving on long steady runs. At wide open throttle, every 50 uses a similar amount, because making 50 HP takes a certain amount of fuel.

Fit a Suzuki multi function gauge that shows fuel flow. Run the boat at a few speeds and note the readings. You will find the sweet spot where the Suzuki DF50ATL2 for sale gives the best distance per liter on your hull, and that is the speed to use for long runs.

Repowering an old two stroke

Many of the Suzuki DF50ATL2 for sale orders we ship are repowers. An old 40 or 50 two stroke comes off, the Suzuki goes on. A few points to plan for:

• Old controls from another brand will not work with Suzuki harnesses. Budget for a Suzuki control box and harness.
• Throttle and shift cables are usually replaced at the same time. Old cables are stiff and can be the wrong type.
• Check the transom for rot around the old bolt holes before hanging the new motor.
• Remove the old oil injection tank and lines if there was one. You no longer need them.
• Fit a new water separating fuel filter. Old tanks often hold water and debris that EFI does not like.

The payoff is a quieter boat, no oil mixing and a motor that starts first time.

What you need to rig it

A remote motor needs a helm. Some boats already have everything, others have nothing. Go through this list before you order the Suzuki DF50ATL2 for sale:

1. Control box with throttle, shift and trim switch. Suzuki side mount or binnacle.
2. Harness long enough to reach from helm to motor along the cable path.
3. Throttle and shift cables, two of them, correct length.
4. Steering rated for at least 50 HP. Mechanical cable steering is normal at this size.
5. Key switch if your control box does not have one.
6. Gauges: tachometer, or better a Suzuki multi function gauge for rpm, trim, fuel flow and alarms.
7. Battery: 12 V marine starting battery, sized per the owner’s manual, plus heavy cables and a switch.
8. Fuel: hose with primer bulb, water separating filter, tank.
9. Propeller, see the next section.

You can see genuine Suzuki controls and gauges on the Suzuki genuine parts and accessories page. We can bundle them with the Suzuki DF50ATL2 for sale in a single shipment.

Choosing a propeller

Your target is wide open throttle inside 5,300 to 6,300 rpm with a normal load on board. Most small aluminum and fiberglass boats end up in the low to mid teens of pitch. Too much pitch and the motor lugs. Too little and it hits the limiter.

Send us your boat length, approximate weight, how many people you usually carry and what motor and prop the boat had before. We will suggest a starting prop for the Suzuki DF50ATL2 for sale and you can fine tune from there.

Fitting it yourself or using a shop

If your boat already has suitable Suzuki controls, cables and steering, a capable owner can hang the Suzuki DF50ATL2 for sale in a day. You need an engine hoist, a helper, marine sealant for the bolts and a torque wrench.

For a bare hull or a repower with new controls, we suggest a marine mechanic. Correct cable adjustment and harness routing matter, and a professional install with a test run keeps the warranty paperwork in order. Keep the invoice with your motor documents.

Check your transom height

Take a straight edge and measure vertically from the top of the transom to the bottom of the hull at the keel line. Do not follow the slope of the transom.

• 15 inches: short shaft
• 20 inches: long shaft, which is the Suzuki DF50ATL2 for sale
• 25 inches: extra long shaft

Final mounting height is set with the bracket bolt holes. The cavitation plate should run level with, or just above, the bottom of the hull. Too low adds drag. Too high and the prop can blow out in turns.

Getting the best from the Suzuki DF50ATL2 for sale on the water

Once the motor is hung and propped, a few small things make a big difference. Trim the motor in fully for the hole shot, then trim out slowly once on plane until the steering feels light and the speed stops rising. Too much trim and the prop starts to ventilate. You will hear and feel it.

Weight placement matters on small boats. Moving a battery or a fuel tank forward can help a stern heavy boat plane sooner. Check full throttle rpm with your normal load every season. If the Suzuki DF50ATL2 for sale is running below 5,300 rpm at wide open throttle, find out why before it becomes a habit, because lugging an engine is hard on it.

Last point: keep the hull clean. Growth on the bottom costs more speed and fuel than most people think, and owners often blame the motor for it.

Breaking it in properly

Treat the first ten hours as a running in period. This is how we explain it to buyers of the Suzuki DF50ATL2 for sale. Follow the owner’s manual if anything differs.

• First two hours: low speed, below half throttle. Get on plane briefly, then come back down.
• Third hour: bring it up to about three quarters throttle in short spells.
• Hours four to ten: vary speed a lot. Short full throttle runs are fine.
• Avoid holding the same rpm for long stretches.
• Check oil before every run.

Book the first service at about 20 hours. On the Suzuki DF50ATL2 for sale that is an oil and filter change, gear oil, and a check of all bolts and adjustments.

Routine maintenance

Use Suzuki four stroke marine oil and Suzuki gear oil. The Suzuki DF50ATL2 for sale takes about 2.7 liters of engine oil with a filter change, so servicing it is not expensive.

Salt water habits

Suzuki gives the motor an anti corrosion finish and anodes. Your job is to rinse it. These habits keep a Suzuki DF50ATL2 for sale looking and running right in salt:

• Fresh water flush through the flush port after every salt trip.
• Rinse the outside, especially the bracket and the steering tube.
• Pull the cowl monthly and check for salt crust around the powerhead.
• Replace anodes when half used, and never paint them.
• Use a corrosion inhibitor spray on electrical connectors.
• If the boat lives on a mooring, tilt the motor up out of the water when not in use.

Storing it for the off season

If the boat comes out for a few months, prepare the Suzuki DF50ATL2 for sale before you walk away. It saves trouble in spring.

1. Add stabilizer to the fuel and run the engine long enough for treated fuel to reach the injectors.
2. Flush with fresh water and let it drain.
3. Change engine oil, filter and gear oil now, not in spring.
4. Remove the battery, charge it and keep it on a maintainer at home.
5. Grease all the fittings and spray the powerhead with inhibitor.
6. Leave the motor trimmed down so water drains from the leg.

Spares to keep on board

A spare kill switch lanyard, a set of plugs and a plug spanner, a fuel filter, a prop nut kit with cotter pin and washer, and a few fuses. With these, most small problems on a Suzuki DF50ATL2 for sale are fixable at the ramp or on the water.

Common problems we hear about

Motor cranks but will not start

Check the kill switch lanyard, the fuel tank vent, and squeeze the primer bulb until firm. Most no start calls end there.

Top speed lower than expected

Check full throttle rpm. If it is under 5,300, your prop pitch is probably too high or the motor is mounted too low.

Warning buzzer at speed

Stop and look at the telltale. No stream usually means a blocked intake or a worn impeller. Low oil pressure warnings need checking before you go on.

Rough idle after storage

Old fuel or water in the filter. Drain the separator and put in fresh fuel. The Suzuki DF50ATL2 for sale is EFI, so it clears up quickly once clean fuel arrives.

Trim stops working

Battery voltage first, then fuses and the trim relay plug. Low voltage causes most trim complaints.
