Yamaha 350 HP F350XCC Outboard Motor

Description

Here is a new Yamaha F350XCC for sale: the 350 horsepower Yamaha V8 on a 25 inch shaft, with digital electronic controls and standard rotation. It ships new in its factory crate and we send motors to customers around the world. If you have a big boat with a 25 inch transom and you need serious power, this is a motor worth looking at closely.

Most people think of the F350 on huge 30 inch bracket boats, but plenty of hulls use a 25 inch transom. Large bay boats, big catamarans, some express boats, commercial workboats and older offshore hulls all fall into this group. The F350XCC puts all of that V8 torque on the shorter leg those boats need.

Below you will find full specs, how the X shaft compares with the U shaft, the boats it suits, rigging, running costs, care and ordering. If you need advice on your boat, talk to us.

Yamaha F350XCC Specifications

These are the key figures for the Yamaha F350XCC for sale on this page.

25 Inch or 30 Inch?

The F350 comes on two shaft lengths: X (25 inches) and U (30 inches). The right one depends entirely on your boat.

Measure from the top of the transom, or the mounting surface of your bracket, straight down to the bottom of the hull. Around 25 inches means an X shaft like this Yamaha F350XCC for sale. Around 30 inches means a U shaft like the Yamaha F350UCC.

Too short and the prop will ventilate and lose grip, especially in rough water and turns. Too long and you drag extra gearcase, which costs speed and fuel and throws spray. If your measurement is between sizes, send us photos and boat details. We will help you choose.

Boats That Use a 25 Inch F350

• Large center consoles with 25 inch transoms
• Big bay boats and hybrid boats
• Power catamarans
• Express and walkaround boats
• Commercial workboats, patrol and rescue boats
• Older offshore boats being repowered

Most of these run twins. For a twin setup, pair the Yamaha F350XCC for sale with the counter-rotating Yamaha LF350XCC.

The Strength of a V8

The F350’s 5.3 litre V8 makes big torque at modest rpm. That is exactly what heavy boats need to get on plane and stay there through rough water with full fuel and a crew aboard. Because the engine is not working at its limit at cruise, it tends to have a long, comfortable life, which is why commercial operators like it.

The V8 is also smooth and quiet for its size. Conversation at the helm at cruise is easy, and there is no smoke or two stroke smell.

Digital Controls

The F350XCC uses digital electronic throttle and shift. The lever is light and precise, shifts are consistent and multi-engine setups can be synchronised. You also get detailed engine information on Yamaha’s digital gauges or compatible displays, including fuel flow, trim, hours, temperature and alarms.

Performance

Performance varies with boat, weight and props. Twin F350s on a large 25 inch transom boat typically give strong acceleration and comfortable cruising speeds in the 30s mph, with top speeds depending heavily on hull design. Your rigger will choose props that let the engines reach 5,000 to 6,000 rpm at full throttle with a normal load.

Props

F350s swing large props, usually 3 or 4 blade stainless. Four blades often grip better in rough water and help low speed planing. On twin setups, both props must match in size and pitch, with opposite rotation. Yamaha’s propeller range includes options for big engines.

Rigging

Installing a Yamaha F350XCC for sale is a professional job. A typical twin install includes:

1. Yamaha digital control binnacle
2. Digital harnesses and hubs
3. Start/stop panels
4. Yamaha digital gauges or compatible displays
5. Hydraulic steering for large twin outboards, with a tie bar
6. Independent fuel feeds and water separating filters
7. Cranking batteries for each engine plus house batteries
8. Matched props

Transom Strength

At roughly 760 pounds each, two F350s add a lot of weight to the stern. The transom must be rated for the total engine weight and power. Inspect it before installation, especially on repowers. Use proper hardware and backing plates, seal holes carefully and re-check bolts after the first few trips.

Repowering

Repowering an older 25 inch boat with F350s gives better economy, quieter running, digital controls and modern reliability. Before ordering, check transom strength, capacity ratings, steering, fuel delivery, electrical capacity and helm space.

Running Costs

Use the octane recommended in the owner’s manual, usually 89. Keep fuel fresh with no more than 10 percent ethanol, and fit water separating filters to each engine. For boats that need this much power, the F350 is reasonably efficient at cruise.

Maintenance

• Engine oil and filter every 100 hours or yearly
• Gear oil
• Fuel filters and separator elements
• Spark plugs as needed
• Anodes
• Grease fittings and tie bars
• Water pump impellers on schedule
• General inspection

Service all engines together. Flush after every salt trip.

Break-in

Follow the owner’s manual. Vary throttle, avoid long full-throttle runs and change oil after break-in.

Catamarans and the F350

Large power catamarans often use 25 inch transoms and twin F350s. Each hull carries one engine, set wide apart, which gives superb low speed control. With counter-rotating props, the cat tracks straight and turns evenly. The V8 torque handles the weight of a big cat easily, and the smooth, quiet running suits cruising. Ask your builder for prop recommendations, since catamarans often need different pitch from monohulls.

Handling Twins

Twin F350s with digital controls make low speed handling easy. Shift one engine forward and the other in reverse to pivot. Use throttle and a little steering to walk the stern toward a dock. At cruise, use synchronisation to keep rpm matched. Practise in open water first.

Fuel Layout

Give each engine its own fuel line and water separating filter so one clogged filter affects only one engine. Check that lines and vents suit two V8s at cruise. Carry spare filters on long trips.

Electrical Setup

Use a dedicated cranking battery for each engine and a house bank for electronics, with switches or relays to protect the cranking batteries. Keep connections clean and tight, use dielectric grease on digital plugs and keep accessories off engine harnesses.

A Working Day on a Big Workboat

The Yamaha F350XCC for sale is a common choice on commercial boats, so here is what a working day can look like.

The crew arrives early. The skipper starts both V8s and they settle into a steady idle while the deck is loaded with gear. The boat leaves the harbour with a heavy load, maybe dive equipment, survey instruments or a charter group. The engines bring the boat onto plane without strain, and the skipper sets a cruise that balances speed and fuel.

Over the day the boat makes several stops. Each time, the digital controls make positioning easy. The skipper uses the throttles to hold the boat steady in current while the crew works. Between stops, the engines run at cruise for long stretches, and the digital display keeps track of fuel used and remaining.

At the end of the day, the boat returns, the engines are flushed and the skipper logs hours and any notes. Day after day, season after season, that is the job these engines were built for. Commercial users choose the F350 because of its torque, its smooth running under load and its long record in hard use.

Service Planning for Heavy Use

If you will run your Yamaha F350XCC for sale for commercial work or very long hours, plan maintenance around that use:

• Service on hours rather than waiting for the yearly date
• Stock common parts such as filters, plugs, anodes and impellers
• Keep detailed logs for every engine
• Schedule services in quiet periods so boats are available when busy
• Check fuel quality regularly, especially if you buy fuel in different ports

A little planning keeps big engines running when you need them most.

Offshore Planning

• Use the rule of thirds for fuel
• Check fuel flow on the display to plan real consumption
• Carry spare filters, prop hardware and tools
• Carry reliable communications and safety gear
• Watch the weather and file a float plan

Salt Water Care

• Flush both engines after every trip
• Rinse cowlings, brackets, trim rams, steering and tie bar
• Check anodes often
• Spray powerheads with corrosion protectant
• Wax cowlings twice a year

Replacing One Engine

If you need to replace one motor from a pair, the Yamaha F350XCC for sale can join an existing XCC partner in good condition. If the remaining engine has very high hours or is a different version, replacing both may be wiser. Send us the details and we will advise you honestly.

Common Mistakes

• Wrong shaft length
• Wrong rotation for the engine position
• Mixing versions without checking
• Undersized steering, fuel lines or batteries
• Skipping break-in
• Not flushing after salt
• Mismatched props

Storage

1. Stabilize fuel and run each engine
2. Change oil and filters
3. Change gear oil
4. Grease fittings and tie bar
5. Trim engines down
6. Maintain or disconnect batteries
7. Spray powerheads with corrosion protectant
8. Cover engines

What Comes in the Crate

The Yamaha F350XCC for sale ships with the outboard and its paperwork. Controls, gauges, steering and props are separate. Record the serial number and keep it safe off the boat.

Questions to Ask Before Ordering

• Is my transom 25 inches?
• Do I need standard rotation for this position?
• Do my other engines match in version?
• Is my boat rated for the total horsepower and weight?
• What is the delivered price?
• Which warranty applies?

Choosing the Right Power for a 25 Inch Boat

Big boats with 25 inch transoms are sometimes rated for anything from twin 250s to twin 350s. How do you decide whether the Yamaha F350XCC for sale is the right choice over something smaller?

Start with the rating. The capacity plate or builder documentation tells you the maximum horsepower and weight the boat is designed for. Never exceed it.

Think about load. If you regularly carry heavy loads, lots of fuel, dive gear, fishing gear or passengers, more power helps. The boat planes easily and keeps a sensible speed without the engines working hard.

Think about conditions. If you run in rough water often, the torque of a V8 lets you hold speed into head seas and climb waves without bogging down.

Think about weight. V8s are heavy. On some boats, a pair of lighter V6s might ride better. Your builder’s recommendation is the best guide.

Think about cost. Bigger motors cost more to buy and fuel. But they are often working less hard at cruise, which can help with long-term reliability.

If you are not sure, send us your boat details and how you use it. We will give you our honest opinion on whether the Yamaha F350XCC for sale is the best fit.

Engine Height and Trim

Start at the builder’s recommended height. In sea trials, check that props grip in turns and rough water, and that engines reach 5,000 to 6,000 rpm at full throttle. Raise engines gradually to reduce drag if possible. Trim up at cruise until speed stops rising. Keep the bow lower in head seas and a little higher in following seas.

Gauges and Data

Yamaha digital gauges and compatible displays show rpm, trim, fuel flow, hours, voltage, temperature and alarms for each engine. Set up a clear engine page on your display. It helps you catch problems early and plan fuel accurately on long runs.

Keeping Records

Keep a log for each engine with hours, services, parts and notes. For commercial boats, logs are often required anyway. For private owners, they make servicing easier and add value at resale. Buyers of big boats look closely at engine histories, and a well documented Yamaha F350XCC for sale pair can make your boat much easier to sell later.

Why Buy From Us

We give you a written delivered price and confirm what warranty applies where you are. If you want photos of the crate or label, we send them. And we stay available after delivery if you need help.

A Weekend Cruise on a Big Catamaran

Not every Yamaha F350XCC for sale goes on a work boat. Plenty end up on big cruising catamarans used for family weekends. Here is what that looks like.

Friday evening the family loads the boat with food, bedding, snorkel gear and a couple of paddleboards. Saturday morning you start the twin V8s, and they idle quietly while everyone settles in. You pivot the cat away from the dock using the throttles. Out in open water you bring the engines up together, and the boat lifts and settles into a smooth cruise. On a catamaran, the ride is stable and dry, and with the V8s you can hold a good speed even with a full load.

You reach a sheltered bay a couple of hours later and anchor for the day. The kids swim, you snorkel, and later you fire up the grill. The house battery runs the fridge and lights, while the cranking batteries stay protected for the morning.

Sunday you cruise home, maybe stopping to troll for fish on the way. Back at the marina, you slide the cat into its berth, flush the engines and unload. It is the kind of easy, reliable weekend that big Yamaha V8s make possible.

Bracket vs Transom Mounting

Some boats mount their engines directly on the transom, while others use a bracket behind it. Brackets move the engines aft, can improve the ride and free up cockpit space, but they change the shaft length you need. If your boat has a bracket, measure from the bracket mounting surface. Many bracket boats need 30 inch motors, while transom-mounted boats with a 25 inch transom use the Yamaha F350XCC for sale here. Always check with your builder if you are unsure.

Understanding the Model Code

Yamaha’s model codes tell you exactly what you are buying. For the Yamaha F350XCC for sale:

• F: four stroke
• 350: horsepower
• X: 25 inch shaft
• CC: the digital electronic control version

Put an L in front, as in LF350XCC, and you have the counter-rotating version. Swap X for U and you have the 30 inch motor. A 2 at the end, as in F350XCC2, marks a later production version. Knowing the code helps you compare listings and make sure the motor matches what your boat already has.

Props and Performance Tuning

Getting the props right on big V8s makes a huge difference. If the engines will not reach 5,000 rpm at full throttle with a normal load, the pitch is too high and the engines are lugging. If they go past 6,000, the pitch is too low. Neither is good for the engines or your fuel bill. A good rigger will test several props during sea trials and pick the pair that gives the best balance of hole shot, cruise efficiency and top speed for your boat. Write down the prop sizes once you find them, and carry spares of the same size and rotation on long trips.

Over time, keep an eye on prop condition. A slightly bent blade can cause vibration and loss of performance. Have damaged props repaired or replaced promptly, and always replace them in matched pairs on twin setups.
