Yamaha 175 HP F175LA Outboard Motor

Description

We have the Yamaha F175LA for sale brand new, still in the factory crate, and we ship it to buyers all over the world. If you have landed on this page you probably already know the F175 by reputation. It is the 175 horsepower version of Yamaha’s 2.8 litre in-line four, the same block that sits under the F200 and the V MAX SHO 150. The “L” means a 20 inch shaft. The “A” is the model code. Put simply, it is the motor a lot of bay boats, center consoles, pontoons and bigger aluminum hulls were built around.

Most people searching for a Yamaha F175LA for sale want three things answered fast: is it really new, will it fit my boat, and can you get it to me. I have tried to put everything on this one page that a buyer usually asks us about over the phone. Specs, what kind of boat it suits, what rigging it needs, what it costs to keep running, and how buying and shipping works with us. If something is missing, send us a message and a real person will answer.

Yamaha F175LA for Sale: The Short Version

Here is what you are buying, in plain terms:

• A new Yamaha F175LA four stroke outboard, 175 hp at the prop
• 2.8 litre (2,785 cc) in-line four cylinder, DOHC, 16 valves
• 20 inch shaft, standard right-hand rotation
• Electronic fuel injection, electric start, power trim and tilt
• Mechanical throttle and shift, so it rigs like most older motors
• 50 amp alternator for your electronics and batteries
• Runs on regular 87 octane unleaded

That is the whole story for a lot of people. They know the boat is rated for 175, they know the transom is 20 inches, and they want a Yamaha. If that is you, the price is at the top of the page and you can add it to the cart. If you want to dig a bit deeper first, keep reading.

Yamaha F175LA Specifications

These are the numbers for the Yamaha F175LA for sale on this page. Weight changes a little depending on the propeller and fluids, so treat it as a close figure, not an exact one.

A few of those lines matter more than the others when you are deciding, so let me go through them.

The 2.8 litre block

Yamaha designed this 2.8 litre block to be lighter and more compact than most V6 options in this power range. Two counterbalance shafts keep it smooth, which you notice at idle and around 3,000 rpm where a lot of four cylinders start to buzz. A knock sensor watches what the engine is doing and lets it run at its best on regular gas. Owners we talk to tend to say the same thing: it starts, it runs, and it does not give much trouble.

Gear ratio and props

The 1.86:1 gear ratio is a bit taller than the F150’s 2.0:1. In practice that means the F175 swings a slightly smaller pitch prop for the same boat, or pushes the same prop a bit faster. Most people end up somewhere in the 15 to 19 pitch range on a 3 blade stainless prop, but the right answer depends on your hull and load. Yamaha’s propeller range for in-line fours is a good place to start looking.

Mechanical controls

This is the big difference between the LA and the LCA. The Yamaha F175LA uses old-school cables. That is a plus for a lot of repowers because you can often keep the existing control box if it is a compatible Yamaha unit, or fit a mechanical box without buying digital harnesses. If you want drive-by-wire, look at the Yamaha F175LCA instead.

Who Should Buy This Yamaha F175LA for Sale

We sell a fair number of these, and the people who order the Yamaha F175LA for sale from us fall into a few groups.

Bay boat and flats owners. A lot of 18 to 21 foot bay boats are rated right at 175. The in-line four is lighter than a V6, which helps the boat sit level and get on plane quickly in shallow water.

Center console owners in the 19 to 22 foot range. If you fish inshore and near-shore and your transom is 20 inches, the Yamaha F175LA for sale here is a solid single-engine choice.

Pontoon owners. Plenty of mid-size tritoons carry a 175 rating. The torque from 2.8 litres moves a loaded pontoon with a full crowd without sounding like it is working hard.

Aluminum fishing boats. Big deep-V aluminum boats for walleye and salmon often run 175. The VTS trolling feature is a big deal for these guys, more on that below.

Commercial and work boats. Small charter and work operators like this motor because parts are easy to get almost anywhere and mechanics know it.

If your boat needs a 25 inch shaft, the Yamaha F175LA is the wrong motor. Go for the Yamaha F175XA instead. Measure from the top of the transom where the motor bolts on, straight down to the bottom of the hull. Around 20 inches means L. Around 25 means X.

How the Yamaha F175LA Runs on the Water

On a typical 19 to 20 foot aluminum or fiberglass boat with two people and normal gear, expect a top end somewhere in the mid 40s mph. Cruise usually falls in the low to mid 30s at around 4,000 to 4,500 rpm. Fuel use at cruise often lands around 4 miles per gallon on a boat that size. These are real-world ballpark numbers, and your boat, load, prop and water will move them around a lot.

Talk to anyone who has run a Yamaha F175LA for sale like this one for a season and you hear the same thing. What people notice more than top speed is how easy it feels. The motor gets the boat up without a lot of bow rise, it does not shudder at low speed, and the Shift Dampener System takes most of the clunk out of dropping into gear. If you are coming off an old two stroke, the quiet is the first thing you will notice. You can hold a conversation at cruise.

Trolling with VTS

The Variable Trolling RPM Switch lets you set idle anywhere from 650 to 900 rpm in 50 rpm steps. You do it from a compatible Yamaha gauge. If you troll for walleye, salmon or anything else that is picky about speed, this saves you from fighting the throttle all day or buying a separate kicker for some setups.

Repowering With a Yamaha F175LA for Sale

A lot of the calls we get are about repowers, and a Yamaha F175LA for sale is one of the most common repower motors people ask us about. The F175 was built with that in mind. It uses 26 inch mounting centers and a bolt pattern that lines up with many older two strokes, so in a lot of cases you are not drilling new holes in the transom.

Here is the checklist I would go through before you order a Yamaha F175LA for sale as a repower motor:

1. Check the capacity plate on the boat. Do not go over the maximum horsepower or the maximum weight.
2. Measure transom height so you know you need a 20 inch shaft.
3. Look at the weight of your old motor. If you are replacing a heavy V6 the boat will sit a little bow-down, which is usually a good thing. If you are replacing a light two stroke, check that the boat still floats right at the stern.
4. Check your controls. A mechanical Yamaha box may be reusable. A different brand will need a new box and cables.
5. Plan for gauges. Yamaha’s Command Link gauges work with this motor. Older analog gauges usually need adapters or replacing.
6. Budget for a prop, a fresh fuel water separator, new fuel lines if yours are old, and batteries that can handle the 50 amp charging.

If you are not sure about any of that, send us your boat make, model, year and what motor is on it now. We will tell you honestly whether this is the right fit.

Rigging Your Yamaha F175LA

Buying a Yamaha F175LA for sale is only part of the job. The motor comes as the powerhead and lower unit. You still need the parts that connect it to your boat. For a typical install that means:

• Mechanical remote control box (Yamaha 703 style or newer mechanical box)
• Throttle and shift cables cut to the right length
• Main engine wiring harness for your gauges and key switch
• Gauges, either Command Link or Command Link Plus compatible
• Steering, cable or hydraulic, sized for 175 hp
• Fuel hose, primer bulb and a 10 micron fuel water separator
• Battery cables and a marine starting battery
• A propeller that suits your boat

A good marine mechanic can rig it in a day if the boat is ready. Make sure whoever does it sets the motor height correctly. Too low and you lose speed to drag. Too high and the prop blows out in turns. On most boats the anti-ventilation plate should sit level with or slightly above the bottom of the hull, then fine-tune from there.

Running Costs and Fuel

One reason people go looking for a Yamaha F175LA for sale instead of bigger V6 motors is cost to run. It burns regular 87 octane, so you are not paying for premium at the dock. EFI keeps fuel use sensible at cruise, and the four stroke design means you are not mixing oil.

Stick to fuel with no more than 10 percent ethanol and use a good stabilizer if the boat sits. Most of the fuel problems we hear about on any brand come from old gas sitting in the tank over winter, not from the motor itself.

Maintenance Schedule

If you buy the Yamaha F175LA for sale here, plan on regular servicing from day one. Yamaha’s general rule is a service every 100 hours or once a year, whichever comes first. For a motor like this, a normal yearly service looks like:

• Engine oil and filter change (about 4.5 L of Yamalube 4M or the equivalent your manual calls for)
• Lower unit gear oil change, and look for water or metal in the old oil
• Replace the fuel filter and check the water separator
• Check and grease every fitting on the bracket and swivel
• Check the anodes and replace them if they are worn halfway
• Inspect spark plugs, replace as needed
• Water pump impeller every two to three years, or sooner in sandy water
• Check the timing belt condition as the hours go up

Flush the motor with fresh water after every saltwater trip. It takes ten minutes and it is the cheapest thing you can do for a long life. With regular care, Yamaha four strokes in this class often go well past 2,000 hours. We have heard of plenty that went much further.

Break-In: The First 10 Hours

Every new Yamaha F175LA for sale that leaves our yard needs a short break-in. Your owner’s manual has the exact steps, but the idea is simple. Run it gently for the first hour, then vary the throttle for the next several hours. Avoid holding it at one speed for long and keep wide open throttle short until you are past the break-in period. Check the oil level often. After the first 20 hours or so, it is a good idea to do an early oil and gear oil change.

How It Compares to Its Brothers

We stock most of the 175 range, so here is a quick way to pick between them.

• Yamaha F175LA for sale (this one): 20 inch shaft, mechanical controls. The simple, rig-anywhere option.
• Yamaha F175XA: same motor with a 25 inch shaft.
• Yamaha F175LCA and F175XCA: digital electronic controls. Smoother throttle, but you need the digital rigging.
• Yamaha LF175XCA: counter-rotation, for the second motor on a twin setup.
• Yamaha VF175LA V MAX SHO: the performance version for bass and fast flats boats.

Thinking about one step down or up? The Yamaha F150 is a little less money and sips a bit less fuel. The Yamaha F200 uses the same block with variable cam timing and wants 89 octane. For most boats rated at 175, the F175 is the sweet spot. You can see everything in this power range in our 175 HP Yamaha outboards section.

Why the Yamaha F175 Keeps Selling

There are flashier motors out there. There are faster ones. But when a guy calls asking what to put on a 20 foot boat that he wants to run for the next ten years, the Yamaha F175 comes up again and again, and that is why we list the Yamaha F175LA for sale on the site. It is light for its power. It runs on cheap gas. It is easy to service. And just about every marina in the world has someone who has worked on one.

That last point gets overlooked. If you are cruising, fishing far from home, or running a boat in a place where parts take a while to arrive, buying a motor that local mechanics already understand is worth a lot. Yamaha’s official outboard site lists dealers and service points across many countries, and the parts for this 2.8 litre block are common.

Yamaha Motor Canada’s F175 page also has the factory feature list if you want to check the details yourself.

Things to Check Before You Pay

I tell every buyer the same thing on the phone. Before you click buy on any Yamaha F175LA for sale, whether it is ours or someone else’s, check a few basics. Make sure the model code on the listing matches what your boat needs. Make sure the seller tells you the shaft length in inches, not just “long shaft”. Ask whether the motor is new in the crate or a used unit that has been cleaned up. And ask for a real delivered price to your door or port, so you are not surprised by freight later.

We are happy to answer all of that in writing. If a seller will not, that tells you something.

Single or twin?

Some bigger boats run two 175s instead of one 300. If that is your plan, you need one standard rotation motor and one counter-rotation motor. The Yamaha F175LA for sale on this page is standard rotation. Pair it with a counter-rotating unit and both motors need matching controls, so talk to us first and we will make sure the pair works together.

Storage and winter

If your boat sits for months, run stabilized fuel through it, change the oil before storage rather than after, and keep the lower unit full of fresh gear oil so no water sits in it over the cold months. Store it trimmed down so water drains out of the lower unit. These small habits are what keep a motor like this going for many seasons.
