YAMAHA 40 HP F40LA OUTBOARD MOTOR

Description

We have a new Yamaha F40LA for sale, in its factory crate and ready to ship to you anywhere in the world. The F40LA is Yamaha’s 40 horsepower three-cylinder four-stroke with remote controls and a 20 inch shaft. Yamaha describes its 747 cc 40 HP midrange as giving powerful performance in a compact package, with easy starts, fast acceleration and excellent top-end speed. That is a fair summary. It is light, strong and simple, and it suits a huge range of small boats.

Below you will find the full specs, which boats suit a 40, how to set it up, how to look after it and how to order. For a delivered price now, send us a message.

Yamaha F40LA Specifications

Every Yamaha F40LA for sale on our site is new and matches this sheet.

Why a 40 Is Such a Useful Size

The 40 HP class sits in a sweet spot. It is enough power to plane a 16 or 17 foot aluminium boat with three people, push a small pontoon at a comfortable speed, or pull a kid on a tube. Yet it is light enough not to weigh down a small transom, and frugal enough that a day on the water costs very little in fuel.

A lot of boats are rated for exactly 40 HP. If yours is, a 40 gets the most out of it. And the F40 does that with a smooth, quiet three-cylinder rather than a buzzy twin.

The Engine

The F40LA uses a 747 cc three-cylinder with a single overhead camshaft. Three cylinders give smoother running and less vibration than a twin. Yamaha’s long-track intake manifold and single throttle valve help it make strong torque low down and respond quickly. Electronic fuel injection, controlled by an engine control module, meters fuel precisely. That means easy starts hot or cold, a steady idle, clean throttle response and good fuel economy.

The engine control module also talks to Yamaha digital gauges, so you can display rpm, hours and warnings at the helm. The 17 amp alternator keeps your starting battery charged and supports a fish finder, GPS, radio and lights.

Corrosion protection includes Yamaha’s YDC-30 aluminium alloy and a five-layer anti-corrosion paint system, standard on its midrange four-strokes. With regular flushing, the Yamaha F40LA for sale here holds up well in salt water.

Boats That Suit It

• Aluminium V-hull fishing boats, 15 to 17 feet, with a side console
• Small fibreglass skiffs and centre consoles
• Pontoons around 16 to 20 feet
• RIBs and inflatables rated for 40 HP
• Jon boats with a console
• Yacht tenders
• Small workboats and water taxis in sheltered water

Check the capacity plate and measure the transom. If the boat is rated for 40 HP or more and the transom is about 20 inches tall, the Yamaha F40LA for sale here should fit. For a 25 inch transom, ask us about the X shaft version.

On the Water

Turn the key and it starts. It idles quietly, with very little vibration. Push the throttle forward and a typical 16 foot aluminium boat with a couple of people gets on plane quickly and cleanly. The three-cylinder pulls smoothly through the rev range and holds a relaxed cruise without fuss. You can talk normally at cruise. There is no smoke and no two-stroke smell.

Owners coming from an old two-stroke 40 often say the four-stroke feels smoother and stronger in the mid range, and they notice the fuel saving within the first few trips.

Remote Controls

The A model uses remote mechanical controls. You steer from a console with a wheel and use a throttle and shift lever. Remote steering is more comfortable on longer runs, keeps your weight forward in the boat for better balance, and leaves the stern clear for fishing. It also gives you a place to mount a gauge, a fish finder and a switch panel.

If you prefer a tiller, the Yamaha F40LEHA is the tiller version of this motor. If you need to run very shallow rocky water, the Yamaha F40JEA is the remote jet version.

Rigging the F40LA

You will need:

• A Yamaha mechanical control box, side mount or top mount.
• Throttle and shift cables of the right length.
• A main wiring harness, key switch and kill switch.
• Steering, usually cable at this size, or hydraulic for a lighter feel.
• A gauge, analogue or Yamaha digital.
• A fuel line with a primer bulb and water-separating filter.
• A marine starting battery in a secure box.
• A prop to suit your boat and load.

If your old motor was a Yamaha with mechanical controls, some of this may be reusable. Have a Yamaha dealer or qualified mechanic install it. They will set the mounting height, adjust the cables, set up the steering and test the motor on the water. Warranty terms depend on your country, so ask your local dealer once the Yamaha F40LA for sale is registered.

Mounting Height

A good starting point is to set the anti-ventilation plate, the flat plate just above the prop, roughly level with the bottom of the hull. If the prop ventilates in turns, lower the motor a hole. If the boat throws a lot of spray and feels slow, try raising it one hole. Small changes make a noticeable difference on light boats.

Choosing a Prop

You want the motor to reach its full throttle range of 5,000 to 6,000 rpm with your normal load. If it falls short, drop pitch. If it over-revs, go up. On small boats, load varies a lot, so choose for how you usually run. Aluminium props are the standard choice at 40 HP and are cheap to replace. Stainless props give better grip and a little more speed on faster hulls. Yamaha’s propeller guide is a good reference, or tell us your boat and we will suggest one to ship with the Yamaha F40LA for sale.

Variable Trolling

Yamaha’s midrange motors can use variable trolling rpm, which lets you adjust idle speed in 50 rpm steps. On a remote motor, that works through a compatible Yamaha digital gauge or a helm-mounted switch. Anglers who troll find it very handy for holding an exact speed in wind and current. Ask us if you want it set up.

Break-in

Ten hours of gentle running. Start at low speeds, gradually use more throttle while varying the rpm, and avoid long runs at full throttle until the break-in is done. The manual in the crate gives each stage. After the break-in, change the engine oil and filter and the gear lube.

Maintenance

• Flush after every trip using the freshwater flush device. It works without running the engine.
• Check the tell-tale every time you start.
• Change oil and filter at the hours in the manual or each season.
• Change gear lube every season and check it for water.
• Replace the water pump impeller on schedule.
• Check anodes and replace them when worn.
• Keep fuel fresh and the filter clean.
• Grease the steering, swivel and tilt points.

Most of that you can do yourself. Stick to it, and the Yamaha F40LA for sale here will give you many years of easy running.

Pontoons and the F40

Small pontoons are one of the most popular homes for a 40. On a 16 to 20 foot two-tube pontoon with a family on board, the F40 gives a comfortable cruise, enough push to get moving with a full load, and very low fuel use on long, lazy days. Choose a prop with a bit less pitch so the motor reaches its rpm range with weight on board. Some owners like a four-blade prop on pontoons for better grip and smoother turns.

If your pontoon is a heavy tritoon or you regularly carry eight or more people, you may want a bigger motor. For typical small pontoons, the Yamaha F40LA for sale here is a great match.

Aluminium Fishing Boats

On a 15 to 17 foot aluminium V-hull with a side console, the F40 is a natural fit. It gets the boat on plane quickly with two or three anglers and gear, cruises across a lake comfortably, and idles smoothly for trolling. The three-cylinder’s smoothness helps reduce rattles and vibration in the hull. Add a Yamaha digital gauge with variable trolling and you have a very capable fishing setup.

RIBs and Tenders

RIB owners like the F40’s light weight, which keeps the boat balanced and quick to plane. Remote steering lets you stand at a console instead of sitting on the tube. On yacht tenders, the F40’s easy starting and quiet running are big pluses, especially at night in a calm anchorage. Flush after every saltwater trip and keep anodes in good shape.

Salt Water Care

Salt never stops working on metal. Flush the motor with fresh water after every saltwater trip using the flush device. Rinse the outside, especially around the bracket and gearcase. Check anodes monthly and replace them when half worn. Tilt the motor up when the boat is moored so the gearcase is not sitting in salt water. Spray electrical connections with a corrosion inhibitor every few months. Combined with Yamaha’s YDC-30 alloy and five-layer paint, those habits keep the Yamaha F40LA for sale looking and running well.

Winter Storage

Fill the tank and add fuel stabiliser, then run the motor so treated fuel reaches the injectors. Change the oil and filter. Change the gear lube and check it for water. Flush and let the motor drain in the down position. Fog the engine as the manual explains. Grease every fitting. Put the battery on a maintainer and cover the motor. In spring, check it over and start it on water before your first trip.

Upgrading From a Two-Stroke 40

If you are replacing an old two-stroke 40, expect a quieter, smoother motor that starts more easily and uses much less fuel. No oil mixing, no smoke and no fouled plugs after trolling. The four-stroke is a little heavier, so check the boat’s balance and move the battery and fuel tank forward if the stern sits low. Replace old fuel hoses and fit a new water-separating filter. Most owners say the switch to the Yamaha F40LA for sale here is the best upgrade they have made to their boat.

What It Costs to Run

A fuel-injected 40 is cheap to own. Fuel use is low, there is no two-stroke oil to buy, and service parts for the Yamaha three-cylinder are common and affordable. Oil, a filter, gear lube, plugs, an impeller and anodes are about all it needs on a regular basis. Breakdowns are rare on a well-kept motor. When you work out the real cost of the Yamaha F40LA for sale here, the low running costs over the years matter as much as the purchase price.

Resale counts too. Boats with a clean, documented Yamaha on the back sell faster. Keep your receipts and a simple log of hours and services.

New vs Used

Used 40s are easy to find, but small motors often have hard lives. Missed flushes, old fuel left in the system, rocks and sandbars, years in the sun. A used motor can look clean and still have a tired water pump, corroded passages or a worn gearcase. A new Yamaha F40LA for sale from us comes with zero hours and full paperwork, so you know exactly what you are getting.

Choosing Between 30, 40 and 50

If your boat is rated for 30 HP, the F30 is your motor. If it is rated for 40 and you carry three or four people, run in rougher water or tow a tube, the 40 is worth the step up. It uses the same 747 cc block as the 30, so the weight is the same. If your boat is rated for 50 or more and you run heavier loads, the four-cylinder F50 gives you more torque. For most 15 to 17 foot boats rated for 40, the Yamaha F40LA for sale here is the sweet spot.

Fleet and Rental Use

Lake rental fleets, fishing camps and marinas often run a lot of 40s. Easy starting, smooth running and simple servicing make them ideal. Keep every boat on the same model and one set of spares covers them all. If you need several Yamaha F40LA for sale units, tell us the number and we will quote them together. Shipping them in one order usually lowers the cost per motor.

Spare Parts

If you live far from a Yamaha dealer, add a small kit to your order: engine oil and a filter, gear lube, a water pump impeller kit, spark plugs, a fuel filter, a spare prop and anodes. That covers the first season or two. We will ship it with the motor.

A Day on the Lake

Here is what owning one is like. You launch a 16 foot aluminium boat at a lake ramp on a summer morning. You turn the key and the Yamaha F40LA for sale you bought this spring fires straight away. It idles so quietly you can hear the water slapping the dock. Your kids climb in, you idle out past the no-wake buoys, and you push the throttle forward. The boat climbs onto plane without the bow pointing at the sky, and you settle into an easy cruise across the lake.

You fish for a couple of hours, using the gauge to bump the trolling speed up a notch until the lures run just right. After lunch you pull the kids around on a tube for a while. The motor handles it without straining. On the way back, you notice the fuel gauge has barely moved.

At the ramp you hook a hose to the flush port while you load the boat, rinse the motor, tilt it up and head home. No oil mixing, no smoke, no fouled plugs, no fuss. That is the real reason people buy the Yamaha F40LA for sale: it makes boating easy.

Getting the Best Fuel Economy

A few habits stretch your fuel even further. Trim the motor out a little once you are on plane so the bow lifts and the hull drags less. Find the rpm where the boat runs flat and smooth, and cruise there instead of at full throttle. Keep the hull clean, because growth on the bottom costs fuel. Do not carry gear you do not need. And use a prop that lets the motor reach its rpm range with your usual load. Small changes add up over a season, and the Yamaha F40LA for sale rewards a little care with very low running costs.
