Tohatsu MFS9.8BL 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 MFS9.8B page.

What the Model Code on the Tohatsu MFS9.8BL for sale Means

Tohatsu codes are easy once someone explains them. MFS means a Tohatsu four stroke and 9.8 is the horsepower. The B after the horsepower marks the model series. The L at the end means a long 20 inch shaft.

The Tohatsu MFS9.8BL for sale and the 209 cc Twin

The MFS9.8B uses Tohatsu’s 209 cc two cylinder four stroke tuned to 9.8 horsepower. It is the most powerful motor in the light twin family and still weighs only around 37 to 42 kg depending on the version.

Many owners choose 9.8 over 9.9 because of the weight. It is noticeably lighter than the bigger 333 cc 9.9 EFI, which matters if you lift it on and off a tender.

Standard kit includes forward, neutral and reverse, a separate 12 litre tank, thermostat controlled cooling and an oil pressure warning. Plenty of buyers message us before ordering the Tohatsu MFS9.8BL for sale, and we like that.

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 MFS9.8BL for sale has a 20 inch shaft.

Fitting It to Your Boat

Place the motor in the middle of the transom, tighten both clamp screws and recheck them after a short run. Adjust the trim rod so the motor is vertical when the boat is under way. If you can, use a safety lanyard or chain between the motor and a strong point on the boat. It is cheap insurance. Keep that in mind with the Tohatsu MFS9.8BL for sale.

Tohatsu MFS9.8BL for sale or the 9.9 EFI?

The MFS9.9E uses a bigger 333 cc engine with fuel injection. It has more torque but weighs a few kilos more.

The Tohatsu MFS9.8BL for sale is the lighter, simpler choice and is easy on the wallet.

Who Buys the Tohatsu MFS9.8BL 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.

The First Trip

On the first outing keep it simple. Check the oil level before you clamp the motor on, tighten the clamp screws properly, and tie a light safety line from the motor bracket to the boat. People do drop outboards over the side, usually on the day they skip that line.

Run at varied low and mid throttle for the first stretch, as the break in notes say. Watch the tell tale, listen for anything that sounds odd, and get used to how the boat turns. By the end of the afternoon you will know how the 9.8 HP motor behaves with your load on board.

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. That applies to the Tohatsu MFS9.8BL for sale as much as any motor.

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.

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. Many repeat customers come back for a second Tohatsu MFS9.8BL for sale.

Day to Day Use

A good small outboard should not need much thought. The Tohatsu MFS9.8BL 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 MFS9.8BL 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 MFS9.8BL 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.

Keeping the Cooling System Healthy

The tell tale stream is your early warning. If it slows down or stops, the usual causes are a blocked tell tale hole, weed on the water intake, or a worn impeller.

Clear the tell tale with a bit of wire first. If the stream stays weak, the impeller is the next suspect. Plan to change it every two to three years anyway, and carry a spare on long trips. Never run the motor out of the water without a flushing attachment and the water turned on. The Tohatsu MFS9.8BL for sale is covered here too.

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.

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. It is worth remembering when you run the Tohatsu MFS9.8BL for sale.

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.

What It Costs to Run

Economical at cruise. The 12 litre tank gives plenty of range for most days on the water.

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. That is a big part of why people choose the Tohatsu MFS9.8BL for sale.

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.

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. Owners of the Tohatsu MFS9.8BL for sale tell us the same thing.

Choosing a Propeller

The right prop lets the motor reach its full throttle range of the range in the owner’s manual with your normal load. If it over revs, go up in pitch. If it cannot reach the range, come down. Tohatsu lists a propeller range listed in the manual for this motor. Tell us your boat and load and we will suggest a starting point.

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. It is one of the reasons we keep the Tohatsu MFS9.8BL for sale in stock.

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.

Carrying and Laying Down the Motor

Four strokes have an oil sump, so they care which way you lay them down. Tohatsu marks the correct side on the motor and in the manual. Lay it the wrong way and oil can run into places it should not go, which leads to smoke and hard starting later.

Drain the carburettor or run it dry if you will store it on its side for a while. Carry it upright by the handle when you can, and use a padded bracket or stand at home. A motor stand is cheap and saves the cowling from scratches. You get all of that with the Tohatsu MFS9.8BL for sale.

Simple Fixes Before You Call a Mechanic

No start: kill switch clip on, vent open, fresh fuel, choke used.

Rough running: stale fuel or a dirty filter.

Overheating: weed in the intake or a worn impeller. Ask us if you want photos of the Tohatsu MFS9.8BL for sale before it ships.

Slipping or slow: damaged or wrong prop.

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. We are happy to answer questions about the Tohatsu MFS9.8BL for sale by email or chat.

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.

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. The Tohatsu MFS9.8BL for sale handles this well.

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 MFS9.8BL 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.

Mistakes We See Buyers Make

Buying the wrong shaft length is the big one. Next is leaving old fuel in the motor over winter. Then storing a four stroke on the wrong side and getting oil into the cylinder. And finally forgetting to tighten the clamp screws. All easy to avoid.

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 MFS9.8BL for sale will give you many trouble free seasons.
