Yamaha 350 HP LF350XCC Outboard Motor

Description

Here is a new Yamaha LF350XCC for sale, Yamaha’s counter-rotating 350 horsepower V8 on a 25 inch shaft, with digital controls. It ships in its factory crate and we send it to buyers worldwide. If your boat runs twin F350s on a 25 inch transom, this is the engine for the port side, balancing the standard rotation F350XCC on starboard.

Twin F350s on 25 inch transoms are common on big power catamarans, large bay boats, express boats and commercial workboats. The counter-rotating engine is what makes those boats track straight and handle predictably. Without it, a pair of big V8s would drag the stern to one side every time you push the throttles forward.

On this page you will find specs, matching advice, rigging, care tips and ordering details. If you need help with your setup, talk to us.

Specifications

Main figures for the Yamaha LF350XCC for sale on this listing:

Matching the Pair

Twin engines should match in every way except rotation:

• Same horsepower: both 350
• Same shaft: both 25 inch
• Same controls: both digital
• Same version: this is the XCC version. For XCC2 sets, choose the Yamaha LF350XCC2.
• Matched props, opposite rotation

The standard rotation partner of the Yamaha LF350XCC for sale is the Yamaha F350XCC.

Why Counter-Rotation?

Props push sideways as well as forward. Two big props turning the same way pull the boat to one side. One standard and one counter-rotating prop cancel each other out, so the boat runs straight, turns evenly and backs up cleanly. With 700 horsepower on the transom, balance is not optional.

Which side?

Most twin boats put the counter-rotating engine on port and the standard engine on starboard, with the tops of the props turning outward. Follow your builder’s specification.

Left-hand props

The LF350XCC needs left-hand props. Buy props as a matched pair. Yamaha has propellers for big engines in both rotations.

Boats That Use It

• Large power catamarans
• Big center consoles with 25 inch transoms
• Bay boats and hybrids
• Express and walkaround boats
• Commercial, patrol and survey boats

V8 Torque and Durability

The 5.3 litre V8 makes strong torque without high rpm. Heavy boats plane easily, hold speed in rough water and carry big loads comfortably. Engines that are not working at their limit tend to last a long time, which is why the F350 is trusted for commercial and long-range use.

Digital Controls

Digital throttle and shift give a light lever and clean shifts. The binnacle can synchronise the engines, and Yamaha’s digital gauges or compatible displays show detailed data for each engine.

Rigging

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

Running Costs

Use the octane in the owner’s manual, usually 89, with fresh fuel and good filters on each engine.

Maintenance

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

Break-in

Follow the owner’s manual. Vary throttle and change oil after break-in.

Twin F350s on a Power Catamaran

Power catamarans are one of the most common homes for the Yamaha LF350XCC for sale and its standard rotation partner. Each hull carries one engine, set far apart, which gives a huge lever arm for steering with the throttles. With counter-rotating props, the cat tracks perfectly straight at cruise and turns equally well both ways.

Catamarans are sensitive to weight at the stern, and V8s are heavy, so builders design the hulls around that weight. Follow the builder’s horsepower and weight ratings exactly. Cats also ride higher than monohulls and often need different prop pitch, so ask the builder for recommended props and confirm them during sea trials.

On the water, twin F350s give a big cat strong acceleration, an easy cruise and the torque to push through head seas. At low speed, you can spin the boat in its own length with opposite shifts, which makes docking a large cat surprisingly easy.

Handling Twins

• Pivot: one engine forward, the other in reverse
• Walk sideways: opposite shifts with a little helm
• Hold position: small bursts on each engine in wind or current
• Cruise: use synchronisation to keep rpm matched
• Get home: tilt a failed engine up and run on the other

Practise in open water before tackling busy marinas.

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, a house bank for electronics, and 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 Day on a Twin-Engine Workboat

The Yamaha LF350XCC for sale is popular on commercial boats. Here is a typical day on a dive charter with twin F350s on a 25 inch transom.

The crew loads tanks, gear and twelve divers. The skipper starts both engines and walks the boat away from the dock using opposite shifts. Outside the harbour, the engines come up together and the heavily loaded boat climbs onto plane without strain. The skipper sets a cruise that balances speed and fuel.

At the dive site, the skipper uses small bursts on each engine to hold the boat in position while divers enter the water. Between dives, the boat moves to a second site. At the end of the day, the boat returns, the engines are flushed and the hours are logged. Day after day, that is the kind of work these engines were built for.

Service Planning for Heavy Use

• Service on hours rather than the calendar
• Stock filters, plugs, anodes and impellers
• Keep detailed logs for each engine
• Schedule services in quieter periods
• Check fuel quality regularly

Offshore Planning

• Use the rule of thirds for fuel
• Watch real fuel flow on the display
• Carry spare filters, prop hardware and tools
• Carry communications and safety gear
• Check 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

Transom Strength

Two F350s weigh over 1,500 pounds together. Make sure your transom is rated for that weight and power, inspect it carefully before installation, use the specified hardware and backing plates, seal every hole and re-check bolts after the first few trips.

Replacing One Engine

If you are replacing the port engine of an XCC pair, the Yamaha LF350XCC for sale is a direct match. If the starboard engine has very high hours or is a different version, we can help you decide whether to replace both. Send model codes, serial numbers and hours.

Common Mistakes

• Wrong rotation for the position
• Right-hand prop on a counter-rotating engine
• Mixing XCC and XCC2 versions without checking
• Wrong shaft length
• Undersized steering, fuel lines or batteries
• Skipping break-in
• Not flushing after salt

Storage

1. Stabilize fuel and run both engines
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
8. Cover engines

What Comes in the Crate

The Yamaha LF350XCC for sale ships with its paperwork. Controls, gauges, steering and props are separate. Keep the serial number safe off the boat.

Keeping Records

Log hours, services and parts for both engines. Matching records help keep the pair in step and add value at resale.

Choosing Props for Twin F350s

The props you choose shape how the whole boat performs. Most twin F350 setups run 3 or 4 blade stainless props. Four blades generally hold better in rough water and help the boat stay on plane at lower speeds, while three blades can add a little top speed on calm days. Both props must be the same diameter and pitch, with the Yamaha LF350XCC for sale running a left-hand prop and its partner a right-hand prop.

During sea trials, test props until both engines reach the 5,000 to 6,000 rpm range at full throttle with a normal load. Note the sizes and carry a spare in each rotation on long trips. A damaged prop on one side throws off the balance of the whole boat, so repair or replace it quickly.

Engine Height and Trim

Set the engines at the builder’s recommended height and fine-tune during sea trials. Props should grip in turns and rough water. At cruise, trim up until speed stops rising. Keep the bow lower in head seas and a little higher in following seas.

Gauges and Data

Yamaha’s digital gauges and compatible displays show rpm, trim, fuel flow, hours, voltage, temperature and alarms for both engines. A clear engine page on your chartplotter helps you spot problems early and plan fuel accurately on long runs.

Is the Yamaha LF350XCC for Sale Right for You?

The Yamaha LF350XCC for sale is right if your boat runs twin F350s on a 25 inch transom, you need the counter-rotating engine for the port side, and your starboard engine is the F350XCC with digital controls. It is also a great choice if you are buying a new pair and want the XCC version.

It is not right for a single-engine boat, which normally uses standard rotation. It is not right for a 30 inch transom or bracket, which needs a UCC model. And if your other engine is an XCC2 version, the LF350XCC2 is the better match.

Send us photos of your engine labels and transom if you are unsure. We will tell you exactly which motor fits.

Planning a Full Repower

If you are replacing both engines, plan the whole job first: engine version, shaft length, control binnacle, gauges or displays, steering, fuel system updates, batteries and props. Talk to your rigger about timing, then order everything together. We can quote a matched pair, including the Yamaha LF350XCC for sale and the standard rotation F350XCC.

Understanding the Model Code

For the Yamaha LF350XCC for sale: L means counter-rotation, F means four stroke, 350 is the horsepower, X is the 25 inch shaft and CC is the digital control version. The starboard partner, F350XCC, shares everything except the leading L. A 2 at the end of either code marks the later production version.

Running Efficiently

• Use the fuel flow display to find your most efficient cruise
• Trim up until speed stops rising
• Keep the hull clean
• Keep props matched and undamaged
• Carry only what you need
• Keep engines synchronised

Small habits like these cut fuel bills and stretch your range, which matters far offshore.

Looking After Digital Controls

Digital systems are very reliable when looked after. Keep connectors dry and greased, route harnesses away from heat and fuel lines, keep batteries healthy and avoid tapping accessories into engine harnesses. Low voltage and corroded plugs cause most problems people blame on the controls.

Noise and Comfort

Twin F350s are far quieter than the big two strokes they often replace. No smoke at the dock, no oily smell and easy conversation at cruise. Over a long day, that makes everyone aboard less tired.

Why Buy From Us

We help you confirm rotation, shaft length and version before you pay for the Yamaha LF350XCC for sale. You get a written delivered price and a clear answer on warranty in your country. Photos of the crate and label are available, and we stay in touch after delivery.

Questions to Ask Before Ordering

• Does my port position need counter-rotation?
• Is my transom 25 inches?
• Is my starboard engine the XCC version?
• Is the boat rated for twin 350s?
• What is the delivered price?
• Which warranty applies?

Why the 25 Inch Shaft Matters

Shaft length decides where the prop sits under the hull. On a boat with a 25 inch transom, a 30 inch engine would drag extra gearcase through the water, slowing the boat and throwing spray. A 20 inch engine would leave the prop too high, causing ventilation and loss of grip. The Yamaha LF350XCC for sale has the X shaft, sized exactly for 25 inch transoms.

To check, measure from the top of the transom straight down to the bottom of the hull, keeping the tape vertical. If your boat uses a jack plate or bracket, measure from the mounting surface. If the number is close to 25 inches, you are in the right place. If it is closer to 30, you need a UCC model. Send us photos if you are not sure.

Long Range Cruising

Many owners of twin F350 boats like to cruise long distances along the coast or between islands. The torque of the V8s makes heavy cruising loads easy to carry, and the efficient cruise means good range from big tanks. Plan fuel carefully, keep a healthy reserve, carry spares for both engines and check the weather before every leg. With good planning, a pair built around the Yamaha LF350XCC for sale will carry you a long way.

Repowering

Older boats with big two strokes or early four strokes are great candidates for repowering with twin F350s. You gain economy, quieter running, digital controls and modern engine data. Check transom strength, capacity ratings, steering, fuel delivery, electrical capacity and helm space before you order.

Year-Round Boats

If your boat lives in the water, run the engines regularly, keep anodes fresh and follow your dealer’s advice on protecting the lower units from growth. Flush where possible and keep cowlings clean and waxed.

A Weekend Cruise on Twin V8s

Not every Yamaha LF350XCC for sale goes to work. Plenty end up on family cruising boats. Picture a big cruising catamaran heading off for a long weekend.

Friday evening, the family loads food, bedding, snorkels and paddleboards. Saturday morning both engines start quietly and you pivot away from the dock with a couple of gentle shifts. In open water, the engines come up together and the cat settles into a smooth, level cruise. The ride is dry and stable, and even with a full load the V8s hold a good speed without effort.

A few hours later you anchor in a sheltered bay. The kids swim, you snorkel, and the house battery runs the fridge and lights while the cranking batteries stay protected for the morning. Sunday you cruise home slowly, maybe trolling a lure on the way. Back at the marina, you slide into the berth, flush both engines and unload. Easy, comfortable, reliable.

Bracket vs Transom Mounting

Some boats mount engines directly on the transom, others on a bracket behind it. Brackets move the engines aft and can improve the ride, but they change the shaft length you need. Many bracket boats need 30 inch engines, while transom-mounted boats with a 25 inch transom use the Yamaha LF350XCC for sale. Check with your builder if you are unsure.

Commercial Fleets

Operators running several boats often standardise on one F350 version to simplify parts and training. If your fleet already runs XCC engines, the LF350XCC slots straight in. Keep matched props in both rotations in stock, plan services on hours and keep detailed logs for every engine.
