Tohatsu MFS4DDL for sale: Specifications

Specs can change slightly between production runs, so the paperwork in the box is the final word. Tohatsu lists the current figures on its Tohatsu MFS4D page.

What the Model Code on the Tohatsu MFS4DDL for sale Means

Tohatsu codes are easy once someone explains them. MFS means a Tohatsu four stroke and 4 is the horsepower. The D after the horsepower marks the model series. The D after the series letter marks the version with a built in fuel tank. The L at the end means a long 20 inch shaft.

Inside the Tohatsu MFS4DDL for sale

The MFS4D uses Tohatsu’s 123 cc single cylinder four stroke, the same block found in the 5 and 6 HP. Running at 4 horsepower it is relaxed and quiet.

You get a proper forward, neutral and reverse gearbox with the shift lever on the front of the motor, a built in 1.1 litre tank and a fitted connector so you can run from a bigger external tank on longer trips.

Tohatsu fits a three way carry handle system and a lay down design, so you can carry it, store it and lay it on its side without oil getting where it should not. It is worth remembering when you run the Tohatsu MFS4DDL for sale.

Boats That Suit the Tohatsu MFS4DDL for sale

Tenders and inflatables

Inflatables up to about 3.2 m.

Small sailboats

Auxiliary power for day sailers.

Jon boats and punts

Lakes, rivers and canals.

Kicker motor

A light trolling or back up motor on a bigger boat.

How the Tohatsu MFS4DDL for sale Runs

The Tohatsu MFS4DDL for sale starts easily and runs smoothly for a single cylinder. Reverse makes docking and backing off a beach a lot easier than on a 2.5 or 3.5.

It pushes a loaded tender or a small aluminium boat at a sensible speed without straining.

About Tohatsu Outboards

Tohatsu is a Japanese company that has specialised in outboards for decades. It is especially strong in portables and mid range motors, and its engines have powered boats under other badges too. For an owner, that means proven designs, wide parts support and a motor that is easy to service almost anywhere.

Short, Long or Ultra Long Shaft?

Measure your transom from the top to the bottom of the hull at the centre. About 15 inches needs a short shaft (S), about 20 inches needs a long shaft (L) and about 25 inches needs an ultra long shaft (UL). Sailboats often need a long or ultra long shaft so the prop stays in the water when the boat pitches. The Tohatsu MFS4DDL for sale has a 20 inch shaft.

Mounting the Motor

Centre the motor on the transom and tighten the clamp screws firmly. Check them again after the first run, because they can loosen with vibration. Set the tilt pin so the motor sits straight up and down when the boat is moving, with the anti-ventilation plate roughly level with the bottom of the hull. Tie a safety line from the motor to the boat in case a clamp ever loosens. That is a big part of why people choose the Tohatsu MFS4DDL for sale.

Tohatsu MFS4DDL for sale or a 5 or 6 HP?

The 5 and 6 HP use the same engine and weigh about the same, with more power.

Choose the Tohatsu MFS4DDL for sale when your boat is rated for 4 HP or you want the gentlest, most economical option.

Who Buys the Tohatsu MFS4DDL for sale From Us

Most buyers are private owners with a tender, a small aluminium boat or a sailboat. After them come fishing guides, rental and sailing clubs, resorts and boat dealers. What they want is simple: a new motor, the right shaft length, proper paperwork and a fair delivered price.

Your First Day Out With the Tohatsu MFS4DDL for sale

Pick a calm day for the first run and stay close to where you launched. Clamp the motor on, fit the kill cord to your wrist or life jacket, open the fuel vent and squeeze the primer bulb until it goes firm. Then start it and let it idle for a minute while you look for the stream of water from the tell tale.

Spend the first hour getting a feel for the tiller, the throttle grip and the gear lever. Practise coming alongside a buoy or a pontoon at low speed. Most people are surprised how quickly a small motor like this starts to feel natural.

Getting the Hang of the Pull Start

A recoil start is one less thing to go wrong. There is no battery to go flat, no starter motor and no wiring to corrode. That is a big plus on a small boat that spends weeks sitting on a trailer or in a shed.

Neutral, throttle on the start mark, choke out when cold, then pull through the slack until you feel compression and give it one smooth pull. Do not let the handle snap back against the cowl. Owners who learn that rhythm rarely need more than two pulls. Owners of the Tohatsu MFS4DDL for sale tell us the same thing.

Steering and Throttle Feel

The twist grip throttle and tiller arm give you direct control. Set the steering friction so the motor stays put when you take your hand off, but still turns without effort.

Remember that an outboard steers by pushing the stern sideways, so the back of the boat swings out when you turn. In a marina, slow down early and use a short burst of reverse to stop. Practise this a few times in open water and the next tight berth will not feel so bad.

Day to Day Use

A good small outboard should not need much thought. The Tohatsu MFS4DDL for sale starts quickly, runs cleanly and needs only basic care: a fresh water flush after salt, a quick look at the oil level and fresh fuel. Do that and it will keep going season after season.

Breaking In the Tohatsu MFS4DDL for sale

Follow the break-in in the owner’s manual. Usually that means low and varied throttle for the first hour, no long runs at full throttle for the first ten hours, and an oil change at the first service. Gentle running at the start helps the motor last.

Keeping the Tohatsu MFS4DDL for sale Healthy

Small outboards need little, but they need it regularly:

• After every trip: flush, rinse and check the tell-tale stream.
• Before every trip: oil level, fuel, clamp screws.
• Every season: engine oil, gear oil, plug, grease.
• Every two to three seasons: water pump impeller.

Keep a note of hours and services. It helps with warranty and resale. It is one of the reasons we keep the Tohatsu MFS4DDL for sale in stock.

The Water Pump Impeller

Every water cooled outboard has a rubber impeller in the lower unit that pushes cooling water up to the engine. Rubber ages, and sand wears the vanes, so it needs replacing every two or three seasons or sooner if you run in sandy water.

The first sign of trouble is a weak or missing stream from the tell tale. Stop the engine if that happens and find the cause. Running a four stroke without cooling water for even a short time can damage it. Changing the impeller is a straightforward job for a dealer or a handy owner.

Why the Anodes Matter

The small metal blocks on the gearcase and bracket are sacrificial anodes. In salt or brackish water they corrode instead of the aluminium housing. That is their whole job. You get all of that with the Tohatsu MFS4DDL for sale.

A quick look each time you flush the motor tells you how they are doing. Swap them when they are worn to about half their size, and keep the contact surfaces clean and bare. A set of anodes costs little next to a pitted gearcase, so keep a spare set with your tools.

Gearcase Oil, Once a Year

Draining the gear oil every season takes about twenty minutes. Lay out a tray, remove the drain screw at the bottom and the vent screw higher up, and let it empty.

Milky or grey oil is a warning sign of water in the gearcase. Metal flakes on the drain screw magnet are another. Refill from the bottom using a pump tube until oil appears at the vent, then refit both screws. Done every year, this little job keeps the gears and bearings in good shape for a long time. Ask us if you want photos of the Tohatsu MFS4DDL for sale before it ships.

What It Costs to Run

The 123 cc four stroke is very economical. The built in tank is fine for short runs, and the external tank connector covers longer days.

Beyond fuel, the costs are oil, a few service parts each season and an impeller every couple of years. For a four stroke motor, that is about as cheap as boating gets.

Keep the Fuel Fresh

Buy fuel from a busy station, use it within a month or so and treat it with stabiliser before storage. Water in fuel causes rough running, so keep tanks topped up and closed. A clean fuel filter and fresh fuel solve most problems before they start. We are happy to answer questions about the Tohatsu MFS4DDL for sale by email or chat.

What It Costs to Own

Fuel is the main running cost, and four strokes are frugal. At part throttle a small Tohatsu sips fuel, so a tank lasts a long time.

Servicing is simple and affordable. Oil, gear oil, a plug and an impeller now and then cover most of it. Flush after salt water use and keep fresh fuel in the tank, and the motor will not ask for much more. That is why so many owners keep the same Tohatsu for ten years or more.

Choosing a Propeller

The right prop lets the motor reach its full throttle range of 4,500 to 5,500 rpm with your normal load. If it over revs, go up in pitch. If it cannot reach the range, come down. Tohatsu lists a 6 to 9 inch pitch for this motor. Tell us your boat and load and we will suggest a starting point. The Tohatsu MFS4DDL for sale handles this well.

Looking After It in Salt Water

Salt is the main enemy of any outboard. A fresh water flush after every trip, a rinse of the outside and an occasional spray of corrosion inhibitor go a long way. Check the anode and replace it when it is half gone.

Laying It Up

Before a long break, flush the motor, run the carburettor dry or stabilise the fuel, change the engine and gear oil and grease every fitting. Store it upright on a stand, under a cover, in a dry place.

Moving the Motor Around

An outboard stand in the garage makes life easier. For the car, keep the motor upright if you can, strapped so it cannot tip. If you lay it down, use the side Tohatsu specifies. Close the vent and tap first. This is where the Tohatsu MFS4DDL for sale earns its keep.

Moving It Around

Small Tohatsu motors are light enough for one person to lift, but treat them with a bit of care. Keep the motor upright as much as you can, and when you need to lay it down in the car, use the side shown in the manual so the oil stays where it belongs.

A blanket in the boot stops the cowl getting marked. On a trailer, support the motor or tilt it up and secure it so it does not bounce on rough roads. A cheap wooden stand in the garage makes storage and maintenance much easier.

Simple Fixes Before You Call a Mechanic

No start: kill switch clip on, vent open, fresh fuel, choke used. Plenty of buyers message us before ordering the Tohatsu MFS4DDL for sale, and we like that.

Rough running: stale fuel or a dirty filter.

Overheating: weed in the intake or a worn impeller.

Slipping or slow: damaged or wrong prop. Keep that in mind with the Tohatsu MFS4DDL for sale.

Vibration: bent prop or loose clamp screws.

What to Carry in the Boat

A few spares cover most things that stop a small outboard on the water. A spare plug, a spare kill cord and a basic tool roll are the essentials. Add a spare propeller pin or prop hardware, a small roll of tape and some cable ties.

A second kill cord is the one people wish they had most. If the first one goes over the side with a person or gets lost, the motor will not start without it. Paddles or oars are worth carrying too, even on a short trip. That applies to the Tohatsu MFS4DDL for sale as much as any motor.

Carry These on Board

Life jackets, oars, a spare kill clip, a plug spanner and spare plug, basic tools, a bailer and a phone in a dry bag. Small boats can get caught out by wind and tide, so plan for the motor stopping, even though it probably will not.

On a Yacht Tender

For tender use, light weight and easy starting matter most. Keep a lanyard on the motor when you move it between boats, use a bracket on the pushpit to store it and flush it now and then with fresh water from the yacht’s tanks.

Matching the Motor to the Boat

The capacity plate tells you the limit. Within that limit, think about load, distance and water conditions. More power helps with heavy loads and wind. Less power saves weight and fuel. Ask us if you want a second opinion on the Tohatsu MFS4DDL for sale.

Coming From an Old Two Stroke

A four stroke is quieter, cleaner and uses far less fuel than an old two stroke. There is no oil to mix and no smoke. It is a little heavier, so check how the boat sits. Most owners never look back. Many repeat customers come back for a second Tohatsu MFS4DDL for sale.

New Versus Second Hand

A used outboard can look like a bargain, but you rarely know its history. Was it flushed after salt water? Was the gear oil ever changed? Has it been dropped or run without water? Those things do not show on the outside.

A new motor comes with a clean history, fresh seals, a factory warranty and a full manual. You run it in yourself, so you know it was done properly. For many buyers that peace of mind is worth the difference in price.

Avoid These Common Errors

Wrong shaft, stale fuel, laying the motor on the wrong side and loose clamps cause most of the trouble we hear about. Measure, use fresh fuel, read the storage page in the manual and check the clamps. That is it. The Tohatsu MFS4DDL for sale is covered here too.

The First Year

Year one is simple: gentle break-in, first service on time, flush after salt, fresh fuel and a proper lay up at the end. Do that and the Tohatsu MFS4DDL for sale will give you many trouble free seasons.

How Delivery Works

We ship worldwide. Once you confirm the order, the Tohatsu MFS4DDL for sale is packed in its original box and booked with a carrier we trust or your own forwarder. You get the paperwork and a tracking number so you can follow it to the end.

About the Warranty

Tohatsu warranty terms vary around the world and between leisure and commercial use. We will tell you what applies in your country. Keep your receipts and service records safe.

Serial Number and Registration

Write down the serial number from the bracket label as soon as the motor arrives, and take a photo of it. Keep it with your receipt. You will need it for warranty claims, for ordering the right parts and for insurance.

Some countries need outboards registered or recorded with the boat. Rules differ a lot, so check what applies where you use the boat. A motor lock on the clamp screws is a good idea too, because small outboards are easy to carry away. It is worth remembering when you run the Tohatsu MFS4DDL for sale.
