Yamaha F150LB 150 hp 20

Description

If you have been looking for a Yamaha F150LB for sale, you are probably in one of two spots. Either your old 150 has finally had enough, or you bought a hull that needs a motor and you want something that will start every single time. This page is about the F150LB: a new, crated Yamaha 150 HP four-stroke with the 20 inch shaft, sold by us and shipped to buyers around the world.

I am going to go through what the motor is, the full specifications, which boats it suits, what it costs to run, and how ordering from us works. No fluff. If you already know you want it, skip to the bottom and send us a message for a delivered price.

Yamaha F150LB Specifications

Those are the numbers that matter when you are fitting a motor. Weight and shaft length decide whether it will sit right on your transom. The alternator output tells you whether it can keep up with your electronics. Displacement is the reason this 150 feels stronger than a lot of other 150s on the water.

What the F150 Actually Is

The Yamaha F150 has been around for a long time, and that is the whole point. It is one of those motors that guides, charter skippers and commercial users keep buying because it just keeps going. The basic design is a big 2.7 litre four-cylinder block with dual overhead cams. Big displacement for a 150 means it does not have to rev hard to make its power, so it lugs a loaded boat out of the hole without screaming.

The “L” in F150LB tells you the shaft is 20 inches. The “B” is the version letter. It is the current mechanical-control version of the F150, which means you run it with ordinary throttle cables and a mechanical shift. For most people repowering a centre console, bay boat or pontoon, that is exactly what they want. No digital network to wire up, no special control box. Any Yamaha mechanical binnacle or side-mount control will run it.

When people ask me why they should pick a Yamaha F150LB for sale over a cheaper brand, my answer is boring: parts and service. Yamaha dealers are everywhere. Mechanics in almost every coastal country have worked on an F150. If something wears out in ten years, you can get it fixed without waiting months for a part. That counts for a lot more than a slightly lower price on day one. It is also why we always keep a Yamaha F150LB for sale on the site.

Which Boats Suit the Yamaha F150LB

The 150 HP class is the sweet spot for a lot of boats. Here are the ones we see it go on most often:

• Centre consoles in the 18 to 22 foot range
• Bay boats and flats boats with a 20 inch transom
• Pontoons and tritoons that need more than 115 but not a 200
• Aluminium fishing boats and walk-arounds
• Work boats, small ferries and dive boats that run all day

Check the capacity plate on your boat first. If it is rated for 150 HP or more and the transom height is 20 inches, the Yamaha F150LB for sale here will bolt on without drama. If your transom is 25 inches, you want the X shaft model instead. Ask us and we will tell you if we have one.

On a pontoon, the F150 is a great match. It has the low-end grunt to get a heavy tritoon up on plane with a full crew and a cooler full of drinks, and it does not drink fuel like a bigger V6 would. That mix is why pontoon owners ask about the Yamaha F150LB for sale more than any other 150 we list. On a bay boat it gives you a good top end and enough torque to pop up in skinny water. On a work boat it is just dependable, which is what you want when the boat is earning money.

Weight and Balance

At 478 pounds, the F150 is not the lightest 150 out there. Some newer designs shave weight. But that weight is a big part of why it lasts. Heavy castings, a large block, and robust internals are what let these motors run thousands of hours in commercial use.

If you are replacing an older two-stroke 150, you will notice the four-stroke is heavier. Have a look at how the boat sits at rest. Most hulls handle the extra weight fine, but on a small boat with a lot of stuff already in the stern, you might want to move batteries or fuel forward a little. It is a small adjustment and worth doing.

If you are replacing an older F150, it is close to a straight swap. Same bolt pattern, same general size. That makes the Yamaha F150LB for sale here an easy upgrade for people who already know and trust the motor.

Fuel Economy and Running Costs

This is where four-strokes pay you back. The F150 is efficient at cruise, and the fuel injection keeps it smooth from idle all the way up. You will see real savings compared to an old carbureted two-stroke, and the motor does not smoke or smell.

Exact fuel burn depends on your hull, your load and your prop, so I am not going to quote a number that might not match your boat. What I can tell you is that owners who switch to an F150 from an older engine nearly always report they are filling up less often. Run it at a sensible cruise, somewhere around 4,000 rpm on most boats, and it sips. That alone is a big part of the appeal of any Yamaha F150LB for sale.

Running costs beyond fuel are low too. Oil changes, a gear lube change, plugs and filters at the service intervals in the owner’s manual. Anodes if you are in salt. That is about it for a well looked-after motor. A Yamaha F150LB for sale here, bought new and kept on schedule, should give you many years before anything major comes up.

The 50 Amp Alternator

This gets overlooked, but it is a big deal on a fishing boat. Modern boats carry chart plotters, fish finders, radios, livewell pumps, bilge pumps, lights, and sometimes a trolling motor charger. All that pulls current. A weak charging system leaves you with flat batteries after a long day.

The F150 puts out up to 50 amps, which is plenty for most setups. It is one of the reasons tournament anglers and charter guys like it. If you are running a lot of electronics, it is worth asking about a battery switch or a dual battery setup when you rig the Yamaha F150LB for sale so the starting battery stays topped up no matter what.

Props and Performance

The prop makes a bigger difference to how a boat runs than most people expect. The right one lets the motor reach its full throttle range of 5,000 to 6,000 rpm with your normal load on board. Too much pitch and the motor will lug and never reach its rpm. Too little and it will hit the rev limiter before the boat is going anywhere.

Yamaha has a good propeller guide on its official site that helps narrow things down by boat type. For the F150, stainless props are popular on bay boats and centre consoles. Aluminium props are fine for pontoons and for people running in shallow, rocky water where you might hit something.

If you are not sure where to start, tell us your boat make, model, length and what you usually carry, and we will point you in the right direction. We can supply props with your Yamaha F150LB for sale order so everything arrives together.

Rigging the Motor

The F150LB is a mechanical-control motor, which keeps rigging simple. You will need:

• A Yamaha mechanical control box (side mount or binnacle)
• Throttle and shift cables of the right length
• A main wiring harness to run from the motor to the helm
• Gauges, either analogue or a Yamaha digital display
• Steering, hydraulic is the norm for this size
• A fuel line with a water-separating filter
• A cranking battery that meets the rating in the manual

If your boat already had a Yamaha 150 on it, a lot of this can stay. Cables might need replacing if they are old and stiff. A good rigger will check all of it. We always suggest having a local Yamaha dealer or a qualified marine mechanic install and commission the motor. It protects your warranty and you get the break-in done right. Every Yamaha F150LB for sale we ship comes with the manual your installer will need.

Break-in

Every new outboard needs a break-in. For the F150 it is ten hours, done in stages. The first hour mostly at low speed, the next stretch with a bit more throttle and varied speeds, and no long runs at full throttle until the time is up. The exact steps are in the owner’s manual that comes with the motor.

Follow them. It is tempting to open a new motor right up on the first day, but a careful break-in is the best thing you can do for its life. After that first ten hours, change the oil and the gear lube. Many owners skip that first oil change, and they should not. If you buy the Yamaha F150LB for sale from us, put that first oil change in your calendar the day it arrives.

Maintenance That Keeps It Running

I will keep this practical. If you do these things, the motor will look after you:

• Flush with fresh water after every trip in salt or brackish water.
• Change engine oil and filter at the intervals in the manual, or once a season, whichever comes first.
• Change the gear lube and look at what comes out. Milky means water got in.
• Check and replace anodes when they are half gone.
• Replace the water pump impeller on schedule. It is cheap and it saves the powerhead.
• Keep fuel filters fresh and use good fuel. Add stabiliser if the boat sits.
• Grease the steering, the tilt tube and the fittings.

None of that is hard. Most owners can do the flush and the grease themselves and leave the rest for a yearly service. The Yamaha F150LB for sale here comes from a line with a long track record because people who look after it get thousands of hours out of it.

F150LB vs Other Yamaha Options

A lot of buyers end up comparing a few models before settling. Here is how the F150 stacks up against its neighbours in our range.

Against the 115: The F115 is lighter and cheaper. If your boat is rated for 115 to 150 and you mostly run light, it might be enough. But the F150 has a lot more torque because of its bigger 2.7 litre block. With a full load, the 150 just does the job with less effort. Have a look at the Yamaha VF115 V MAX SHO if you are on a bass boat and want something lighter and quick.

Against the 175: The F175 is a 2.8 litre four-cylinder and it is lighter than the F150 for its power, but it costs more. If your boat is rated well above 150 and you want more top end, see our 175 HP Yamaha range.

Against the 200: Going to a 200 means a bigger, heavier motor and more fuel. Only worth it if the boat needs it. Our 200 HP Yamaha outboards are listed here if you want to compare.

For a lot of boats, though, the Yamaha F150LB for sale is the right balance of power, weight and cost. It is the reason the 150 class is so popular.

Who Buys the F150 From Us

We sell this motor to private owners, boat dealers, fishing lodges, dive operators and small commercial fleets. Some buy one motor to repower a family boat. Others buy several at once to keep a fleet on the same engine so they only need one set of spares. Either way, the Yamaha F150LB for sale is the same new crated motor.

If you are a dealer or fleet buyer, tell us the quantity when you ask for a quote. We can put together a delivered price for several units at once. That usually brings the per-motor cost down, and it is a lot less paperwork than ordering one at a time.

You can read what other buyers have said on our reviews page, and there is more about who we are on the about page.

How Buying a Yamaha F150LB From Us Works

We keep it simple. Here is the process:

1. Send a message. Use our contact page. Tell us the model, how many you need, and your country and nearest city or port.
2. Get a delivered price. We reply with a quote that covers the motor, crating and shipping to you.
3. Confirm and pay. Once you are happy, we confirm the order and the payment details.
4. We ship. The motor goes out in its factory crate with FedEx, UPS or USPS, and you get tracking.
5. You receive it. Inspect the crate when it arrives, then have it installed and broken in.

We ship worldwide. Import duties and local taxes depend on your country, so it is worth checking with your local customs office before the motor lands so there are no surprises. Our refund and return policy and terms and conditions are on the site if you want to read them first.

What Comes in the Crate

A new F150LB ships in Yamaha’s factory packaging with the motor itself, the owner’s manual and the standard paperwork. Props, controls, gauges and rigging parts are separate, because every boat needs something different. If you want any of those, add them to your enquiry and we will price them together with the Yamaha F150LB for sale so it all arrives in one go.

Keep the paperwork safe. Your local Yamaha dealer will need the serial number to register the motor. Warranty coverage depends on where the motor is installed and registered, so ask a dealer in your country about the terms that apply to you.

Common Mistakes When Buying a 150

I see the same few mistakes over and over, so here they are, in case they save you some money.

Wrong shaft length. Measure from the top of the transom to the bottom of the hull at the centre line. About 20 inches means L. About 25 means X. Do not guess.

Overpowering the boat. Check the capacity plate. Hanging more motor than the boat is rated for is dangerous and can void your insurance.

Mixing control types. The F150LB uses mechanical controls. If your boat has a digital electronic control from a different motor, it will not work with this one. Plan for new controls if needed.

Skipping the break-in. It matters. Do it properly.

Cheap fuel filters. A good water-separating filter is cheap insurance for a fuel-injected motor.

Avoid those, and a Yamaha F150LB for sale from us should be one of the easiest repowers you ever do.

Why the F150 Has Lasted So Long

Some motors come and go. The F150 stayed. It has been updated over the years, with better corrosion protection, better fuel injection and better electrics, but the core idea has not changed. A big, under-stressed four-cylinder that makes 150 HP without working hard.

That is why you still see older F150s running on charter boats with huge hours on them. Ask any guide who runs one every day and they will tell you the same thing. It starts, it runs, it gets them home. That reputation is what you are buying with a Yamaha F150LB for sale. When people come to us looking for a Yamaha F150LB for sale, a lot of them say they had one before and just want another one.

Yamaha’s own official outboard site has more on the wider F150 family if you want to read about the other versions, like the digital-control models and the counter-rotating ones.

Using the Motor in Salt Water

Salt is hard on everything. The F150 is built with that in mind. The aluminium alloy Yamaha uses resists corrosion, the paint system is multi-layer, and there are anodes in the right places to take the hit before the motor does. Still, the owner has a job to do.

Flush after every trip. Rinse the outside too, especially around the bracket and the lower unit. Check anodes. Spray the electrical connections with a marine corrosion inhibitor once in a while. And if the boat lives in the water, tilt the motor up when it is not in use so the lower unit is not sitting in salt all week.

People who do this get a long life out of their motors. People who do not end up replacing parts that should have lasted. The Yamaha F150LB for sale here will hold up well in salt, but only if you meet it halfway.

Variable Trolling and Low Speed Running

If you troll for fish, low-speed control matters. The F150 idles smoothly and can be set up with Yamaha’s variable trolling rpm feature when used with a compatible digital gauge. That lets you adjust trolling speed in small steps without touching the throttle. It is handy for trolling baits at a steady speed, or for idling through no-wake zones without the boat surging.

Ask your rigger to set it up if you want it. It is one of those small things that you end up using every trip once you have it, and it is worth asking for when you rig the Yamaha F150LB for sale.

Shipping a 478 lb Motor Overseas

We get this question a lot. How do you ship something this big and heavy? The answer is the factory crate. Yamaha packs these motors to travel. The crate protects the motor, keeps it upright and has room for the paperwork. We ship with FedEx, UPS and USPS, and we give you tracking from the day it leaves.

When it arrives, check the crate before you sign for it. If there is visible damage to the crate, take photos and note it on the delivery receipt. That makes any claim much easier. Most deliveries arrive with no issues at all, but it is always worth checking.

The Yamaha F150LB for sale here ships to buyers in North America, Europe, Asia, Africa, Australia and the islands. If you are not sure we can reach you, just ask.

Other Yamaha Outboards We Carry

If the 150 is not quite right, we have plenty of other Yamaha models. Have a look at the full Yamaha outboard range, or the newer Yamaha models. If you are thinking about a 90, the Yamaha F90LB is a popular choice for smaller boats. And the main shop lists everything we sell. For tips and buying guides, check our blog.
