Yamaha 175 HP F175XA Outboard Motor

Description

Looking for a Yamaha F175XA for sale? You are in the right place. This is a brand new Yamaha F175XA, the 25 inch shaft version of Yamaha’s 175 horsepower in-line four, with plain mechanical controls. It ships crated, and we send motors to customers around the world.

The XA is the motor for boats with a taller transom. A lot of offshore center consoles, bigger bay boats and some walkarounds were built with a 25 inch transom, and putting a 20 inch motor on them leaves the prop too close to the surface. That is where the F175XA comes in. Same 2.8 litre powerhead as the F175LA, just more leg.

Below you will find specs, a guide to whether the X shaft is right for your hull, rigging notes, running costs, upkeep and how to order. If anything is unclear, ask us. A real person reads every message.

These are the figures for the Yamaha F175XA for sale on this page.

Do You Really Need the 25 Inch Shaft?

This is the most important question on this page. Get the shaft length wrong and nothing else matters. The motor will either drag in the water or suck air and blow out the prop every time you turn.

Here is how to check. Measure from the very top of the transom, where the motor clamps on, straight down to the bottom of the hull at the keel line. Do not follow the slope of the transom, measure vertically. If you are on a jack plate, measure to where the motor bracket will sit.

• About 20 inches: you want an L shaft, like the Yamaha F175LA
• About 25 inches: you want an X shaft, which is this Yamaha F175XA for sale
• About 30 inches: that is a U shaft, normally on much bigger boats and bigger motors

If your number lands between sizes, send us a photo with a tape measure in it. We would rather spend five minutes checking than have you end up with the wrong leg.

Why some boats use a taller transom

Offshore boats and boats that run in rough water often have a 25 inch transom to keep the motor higher, protect the powerhead from following seas and give a deeper prop bite in chop. Many center consoles in the 20 to 24 foot range fall into this group. Pontoons sometimes use a 25 inch mount too, depending on the builder.

Who Buys the Yamaha F175XA for Sale

Our F175XA buyers tend to be running:

• Center consoles from about 20 to 23 feet, used near-shore and offshore on calm days
• Larger bay boats with a 25 inch transom
• Walkaround cabin boats rated for 175
• Tritoon pontoons with a tall motor bracket
• Workboats and small charter boats

The in-line four keeps weight down compared to a V6, which helps smaller offshore boats float level and stay drier at rest. It also means less stress on the transom over the years.

Mechanical Controls: The Simple Choice

The “A” models in the F175 range use cables for throttle and shift. That suits a lot of people. Rigging is straightforward, parts are cheap and easy to find, and any marine mechanic can work on it. If your boat already has a compatible Yamaha mechanical control box in good shape, you may be able to keep it.

The other option is the Yamaha F175XCA, which has the same 25 inch shaft but digital electronic controls. Smoother, lighter feel, but it needs a digital control box and harness. Many repower customers stick with the mechanical Yamaha F175XA for sale here because it fits the helm they already have.

On the Water

On a typical 21 or 22 foot center console with two or three people and fuel aboard, owners usually see a top speed in the low 40s mph and cruise somewhere around 28 to 33 mph at 4,000 to 4,500 rpm. Lighter boats go faster, heavier ones slower. Treat those numbers as a general guide, not a promise.

The 2.8 litre motor pulls well from low rpm, so getting a loaded boat on plane does not take much effort. Two counterbalance shafts keep vibration down. And at cruise it is quiet enough to talk without shouting. If you have come off an older two stroke, you will notice the smell is gone too.

Trolling

With a compatible Yamaha gauge you can set idle from 650 to 900 rpm in 50 rpm steps. Great for trolling for pelagics offshore, or keeping a steady drift speed when you are working a reef.

Props for the XA

Gear ratio is 1.86:1. Most 20 to 22 foot boats end up on a 3 or 4 blade stainless prop in the mid to high teens for pitch. The aim is to hit 5,000 to 6,000 rpm at wide open throttle with a typical load. Yamaha has a range of props made for the in-line four series, which is a good place to start.

Rigging the Yamaha F175XA

When you order the Yamaha F175XA for sale on this page, you get the motor itself. The parts that connect it to your boat are separate. A standard mechanical install needs:

1. A Yamaha mechanical remote control box
2. Throttle and shift cables at the right length
3. Main engine harness to the helm
4. Key switch and gauges (Yamaha Command Link compatible gauges work well)
5. Steering rated for 175 hp, cable or hydraulic
6. Fuel hose, primer bulb and a 10 micron fuel water separator
7. Battery and cables
8. A propeller that suits your boat

Set the motor height so the anti-ventilation plate runs at or slightly above the bottom of the hull, then fine-tune with test runs. A good rigger will do this as part of the job.

Repowering With a Yamaha F175XA for Sale

Plenty of older offshore boats came from the factory with a 25 inch two stroke hanging off the back. Swapping that for a Yamaha F175XA for sale is one of the most popular repowers we see. The 26 inch mounting centers line up with a lot of older motors, so you may not need new holes.

Before you buy, check:

• The capacity plate for maximum horsepower and engine weight
• The transom core, since a soft transom needs fixing first
• Your control box, since another brand will need replacing
• Fuel hoses, tank vents and filters, which often need renewing on older boats
• Battery size, since the 50 amp alternator needs a proper battery to charge

Swapping a heavy V6 for the lighter in-line four usually helps the boat sit level and get on plane sooner. Swapping a light two stroke for it adds some weight at the back, so check the boat still sits right at the dock.

Running Costs

A big reason people go looking for a Yamaha F175XA for sale is that it is cheap to run for the power. Regular 87 octane fuel, four cylinders to service, and decent economy at cruise. On most boats you will burn less than an older V6 of similar power, and maintenance bills tend to be smaller too.

Use fresh fuel with no more than 10 percent ethanol. Fit a water separating filter. Add stabilizer if the boat sits. Most fuel problems come from bad gas, not from the motor.

Service and Care

Yamaha’s service interval is 100 hours or one year, whichever comes first. A normal service on the F175XA covers:

• Engine oil and oil filter
• Lower unit gear oil
• Fuel filter and water separator
• Spark plug check and replacement as needed
• Anodes
• Greasing the swivel bracket, tilt tube and steering
• Water pump impeller every two or three years
• Timing belt inspection

Flush with fresh water after every salt trip. Wash the cowling. Spray the powerhead with a corrosion inhibitor every so often if you run in salt. These motors are tough, but salt is tougher, so stay ahead of it.

Break-in

For the first 10 hours or so, run gently at first and vary the throttle. Avoid long stretches at one rpm and keep full throttle runs short. The owner’s manual lays out the exact steps. Do an early oil change after the break-in hours.

Offshore Use: A Few Practical Points

Since many people buying a Yamaha F175XA for sale plan to run offshore, here are some things worth thinking about.

Single engine range. With one motor, plan your trips with a margin. Carry a VHF, a way to call for help, and enough fuel to get home with plenty left over. A reliable motor is the base, not the whole safety plan.

Fuel filtration. Offshore you are relying on clean fuel. Fit a good 10 micron water separating filter and carry a spare element. Rough seas stir up anything at the bottom of the tank.

Salt. Flush after every trip. Check the anodes more often than you would in fresh water. Keep an eye on the steering cable or hydraulic fittings for corrosion.

Kicker motor. Some offshore anglers add a small kicker as a backup and for trolling. Something like a Yamaha 9.9 high thrust is a common choice. Have a look at our 9.9 HP Yamaha range if you want one.

Why the Yamaha F175 Is Still a Favorite

The 2.8 litre in-line four has built a reputation for being reliable and easy to live with. It is lighter than a V6 of similar output, runs on regular fuel and has parts support in most parts of the world. Mechanics everywhere know it. If you run a boat far from home, or in a place where getting parts can take time, that matters more than an extra few miles an hour at top speed.

Yamaha’s official outboard website has a dealer locator, manuals and accessory information. Yamaha Motor Canada’s F175 page is useful for checking factory features too.

Before You Pay: A Short Checklist

Whether you buy the Yamaha F175XA for sale here or somewhere else, run through this first:

• Confirm the model code matches your shaft length. XA is 25 inch. LA is 20 inch.
• Confirm controls. XA is mechanical. XCA is digital.
• Ask what the price includes. Props and rigging are almost always extra.
• Get a delivered price, not just the motor price.
• Ask if the motor is new or used. This one is new.

Planning twin 175s on a bigger boat? You will need one standard and one counter-rotation motor. This Yamaha F175XA for sale is standard rotation. Talk to us before ordering a pair so we can make sure the motors, shaft lengths and controls all match.

Getting the Most From a 25 Inch Motor

Once the Yamaha F175XA for sale is on your boat, a few setup choices make a real difference to how it runs.

Engine height

Start with the anti-ventilation plate level with the bottom of the hull. Then run the boat. If the motor is smooth and the prop holds in turns, try raising it one hole. Higher usually means less drag and a little more speed. If the prop starts to slip or blow out in turns, go back down. On a jack plate you can play with this more easily, but the idea is the same.

Trim

Run trimmed down to get on plane, then trim up gradually once you are running. Watch the tach. When rpm rises a little without the speed dropping, you are close. Trim too far and the prop starts to ventilate. In rough water, keep the bow a little lower for a softer ride.

Weight

Where you put your load changes how the boat runs. Fuel, coolers and people at the back push the stern down and make it harder to plane. Spread weight forward a bit if the boat struggles to get up. A trim tab system can help on boats that tend to porpoise or lean.

Prop fine-tuning

If the motor hits the top of its rpm range easily with a light load but struggles with a full load, you are probably on the right pitch for normal use and just carrying a lot. If it never reaches 5,000 rpm, the pitch is too high. If it goes over 6,000 rpm, the pitch is too low. A one inch change in pitch moves rpm by roughly 150 to 200 on most boats.

Common Mistakes With New Outboards

We have seen most of these over the years. Avoid them and your Yamaha F175XA for sale will thank you.

• Skipping the break-in. It only takes a few hours of patience.
• Using old fuel. Last year’s gas in the tank can cause rough running and gummed injectors.
• Wrong prop. A prop that lets the motor over-rev or lug hurts performance and the engine.
• Not flushing after salt. Ten minutes of fresh water saves a lot of corrosion.
• Weak batteries. A tired battery makes starting harder and can upset electronics.
• Ignoring the tell-tale. If the water stream from the pee hole gets weak, check it before it becomes an overheat.

A Word on Gauges

Even with mechanical controls, the Yamaha F175XA for sale here works with Yamaha’s Command Link gauges. A digital tach and a multifunction gauge can show rpm, trim angle, engine hours, voltage, oil pressure warnings and fuel flow if you add a flow sensor. Fuel flow is worth having. Once you can see how many litres or gallons an hour you are burning at each rpm, you quickly find the sweet spot for cruising and stretch your range.

If your boat has older analog gauges from another brand, they will not read the Yamaha signals properly. Budget for new gauges in that case. Most people find it is one of the best upgrades in the whole repower, because they finally have proper information at the helm.

Some newer chartplotters can also show engine data over a network gateway. Ask your rigger whether your display supports it. Seeing rpm, fuel use and alarms right on the plotter screen keeps the dash tidy and puts everything in one place when you buy the Yamaha F175XA for sale and set up the helm.
