Tohatsu MFS25DS 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 MFS25D page.

What the Model Code on the Tohatsu MFS25DS for sale Means

Tohatsu codes are easy once someone explains them. MFS means a Tohatsu four stroke and 25 is the horsepower. The D after the horsepower marks the model series. The S at the end means a short 15 inch shaft.

Three Cylinders and Fuel Injection: the Tohatsu MFS25DS for sale

The MFS25D uses a 500 cc three cylinder four stroke with electronic fuel injection. Tohatsu calls it the lightest three cylinder 25 in its class, at about 58 kg for the base model.

The manual start version is battery-less, so the EFI works without a battery. The tiller handle has a stop switch, throttle friction and a four step trolling speed control from 750 to 1,050 rpm. Ask us if you want photos of the Tohatsu MFS25DS for sale before it ships.

Tohatsu also redesigned the gearcase for less drag, moved the engine mounts to cut vibration and fitted a 17.5 amp alternator on electric start models, the best in its class.

The trolling control is a real plus for anglers. Set it and the motor holds a steady slow speed. We are happy to answer questions about the Tohatsu MFS25DS for sale by email or chat.

Why Tohatsu

Tohatsu has built outboards in Japan since 1956 and is one of the biggest makers of small and mid size outboards in the world. Several other brands have sold Tohatsu built motors under their own name over the years. That tells you something about the engineering. Parts are easy to get in most countries and mechanics know these motors well.

Getting the Shaft Length Right

This is the most important measurement. Measure the transom height at the centre. Around 15 inches suits a short shaft, around 20 a long shaft and around 25 an ultra long shaft. Too short and the prop sucks air. Too long and you get drag and spray. The Tohatsu MFS25DS for sale comes with a 15 inch shaft. If you are unsure, send us a photo and the measurement.

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. The Tohatsu MFS25DS for sale handles this well.

Tohatsu MFS25DS for sale or the 30 HP?

The MFS30D uses the same engine and weight with 30 horsepower and a higher rpm range.

The Tohatsu MFS25DS for sale suits boats rated for 25 HP and places with a 25 HP limit.

The People Who Order This Motor

We ship the Tohatsu MFS25DS for sale to weekend boaters, yacht owners who need a tender motor, anglers who want a kicker and small businesses running boats every day. Some order one motor, some order several. We treat every order the same way: confirm the model, quote delivery and keep you updated.

Your First Day Out With the Tohatsu MFS25DS 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. This is where the Tohatsu MFS25DS for sale earns its keep.

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.

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. Plenty of buyers message us before ordering the Tohatsu MFS25DS for sale, and we like that.

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.

Living With the Tohatsu MFS25DS for sale

Owning a Tohatsu portable is easy. Clamp it on, check the oil, connect the fuel, start and go. After the trip, flush it with fresh water, let it drain upright and store it the right way up. There is no oil to mix and no smoke. It just works.

The First Ten Hours

New engines like variety. Keep the Tohatsu MFS25DS for sale below half throttle for the first hour and keep changing speed. After that, use more throttle in short bursts. Change the engine oil and gear oil at the first service the manual lists. It sets the motor up for a long life.

Maintenance on the Tohatsu MFS25DS for sale

• Flush with fresh water after every trip in salt or dirty water.
• Check the engine oil level before each trip.
• Change the engine oil at the hours in the manual, or once a season.
• Change the gear oil every season and look for milky oil.
• Replace the water pump impeller every two to three seasons.
• Check the spark plug and the fuel filter.
• Grease the swivel, clamp screws and tilt points.

Most owners do these jobs themselves. They are simple and need only basic tools.

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. Keep that in mind with the Tohatsu MFS25DS for sale.

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. That applies to the Tohatsu MFS25DS for sale as much as any motor.

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.

Changing the Gear Oil

The gearcase oil is easy to forget because you never see it. Change it once a season. Take out the lower drain screw, then the upper vent screw, and let the old oil run into a tray. Many repeat customers come back for a second Tohatsu MFS25DS for sale.

Look at what comes out. Clean dark oil is normal. Milky oil means water is getting in past a seal, and that should be fixed before it rusts the gears. Refill from the bottom hole with marine gear oil until it comes out of the top, fit the vent screw, then the drain screw. New sealing washers each time are a good habit.

What It Costs to Run

EFI and a smooth three cylinder make the Tohatsu MFS25DS for sale economical. The 25 litre tank gives a good range.

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. The Tohatsu MFS25DS for sale is covered here too.

Fuel Quality Matters

Small motors are sensitive to old fuel. Use fresh petrol, keep the tank cap closed and add a fuel stabiliser if the motor will sit for more than a few weeks. If your fuel contains ethanol, do not leave it in the motor over winter. Most hard starting on small outboards comes back to stale fuel.

Running Costs

Small four strokes are cheap to run. They burn far less fuel than an old two stroke of the same size, and there is no two stroke oil to buy. A day of fishing or exploring often uses only a few litres. It is worth remembering when you run the Tohatsu MFS25DS for sale.

The other costs are small too: engine oil once a season, gear oil, a spark plug now and then, and an impeller every few years. Most of that you can do yourself. Over a few seasons the fuel savings alone go a long way toward the price of the motor.

Choosing a Propeller

The right prop lets the motor reach its full throttle range of 5,000 to 6,000 rpm with your normal load. If it over revs, go up in pitch. If it cannot reach the range, come down. Tohatsu lists a 8 to 14 inch pitch for this motor. Tell us your boat and load and we will suggest a starting point. That is a big part of why people choose the Tohatsu MFS25DS for sale.

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.

Storage and Transport

Store the motor upright on a stand when you can. If you must lay it down, follow the manual and lay it on the correct side so oil does not run into the cylinder. For long storage, drain or stabilise the fuel, change the oil, grease the fittings and keep it somewhere dry. Owners of the Tohatsu MFS25DS for sale tell us the same thing.

Carrying and Car Transport

Carry the motor upright using the handle, and get help with heavier motors. In a car, secure it upright in a stand or lay it on the side the manual allows, with a towel underneath. Close the fuel vent and the fuel tap before moving it.

Common Problems and Quick Checks

Will not start. Check the kill switch clip, the choke, the fuel tap and the tank vent. It is one of the reasons we keep the Tohatsu MFS25DS for sale in stock.

Starts then stops. Usually old fuel or a blocked vent.

Weak tell-tale stream. Clear the outlet. If still weak, have the impeller checked. You get all of that with the Tohatsu MFS25DS for sale.

Loss of power. Check the prop for damage or weed, and the fuel filter.

Oil warning. Stop and check the oil level straight away. Ask us if you want photos of the Tohatsu MFS25DS for sale before it ships.

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.

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.

Kicker and Trolling Use

Many anglers run a small motor as a kicker on a bigger boat. It trolls slower and quieter than the main engine and saves fuel and hours on the big motor. A kicker also gets you home if the main engine fails. Link it to the main steering with a kicker bracket for easy control.

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 MFS25DS for sale.

Two Stroke to Four Stroke

If you are replacing an old two stroke, expect less noise, no smoke, no oil mixing and lower fuel bills. Servicing changes to oil changes like a car engine. The trade is a bit more weight, which most boats handle easily.

Why Buy New

Second hand motors turn up all the time, often with stories attached. Some are fine. Others have hidden corrosion, a tired water pump or water in the gearcase that will cost money soon after you buy.

With a new motor there is nothing hidden. You get the warranty, the paperwork and a motor that has never been abused. You also choose the shaft length and start type you actually need, instead of making do with whatever is for sale locally.

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 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 MFS25DS for sale will give you many trouble free seasons.

How Delivery Works

We ship worldwide. Once you confirm the order, the Tohatsu MFS25DS 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.

In the Box

You get the complete Tohatsu MFS25DS motor, the manual, warranty papers and the standard factory fittings. Anything else, such as a spare prop, a stand or a bigger tank, can be added to the same shipment.
