425HP Yamaha outboards sale-35” shaft 4 stroke LXF425ESA2

Description

Here is a new Yamaha LXF425ESA2 for sale: a counter-rotating 425 horsepower XTO Offshore V8 with a 35 inch shaft, in the A2 production version. It ships new in its factory crate and we deliver to customers in many countries. If your boat runs A2 XTOs on tall 35 inch transoms or brackets, this is the counter-rotating engine you need for the port positions.

The 35 inch E shaft is the longest in the XTO range. It suits the biggest outboard boats, where engines are mounted high on brackets to keep the cockpit dry and the ride smooth, but the props still need to reach deep into the water. The leading L tells you this engine spins its prop the opposite way to a standard XF425, so it can balance a standard engine on the other side of the transom.

Below you will find specifications, the model code explained, matching advice, rigging, running costs, care and ordering. If you need help with your boat, contact us.

Specifications

Reading the Model Code

The Yamaha LXF425ESA2 for sale is easier to understand once you break down the code. L is counter-rotation. XF is the XTO Offshore four stroke series. 425 is the horsepower. E is the 35 inch shaft. SA2 is the model series and A2 production version. The standard rotation partner on the same shaft and version is the XF425ESA2. Change E to U and you get a 30 inch shaft, or X for 25 inches.

The production version is the detail that most often trips people up. XTOs on the same boat share a control network and coordinated steering. Matching the version keeps software, displays, joystick systems and service parts consistent across every engine. That is why we always check what you already have.

Matching Your Set

Check four things before ordering the Yamaha LXF425ESA2 for sale. The shaft should be 35 inches, matching your transom or bracket and other engines. The rotation should be right for the position, with counter-rotating engines usually on the port side. The version should match, so A2 goes with A2. And all props should match in size and pitch, with left-hand props on counter-rotating engines.

The standard rotation A2 partner is the Yamaha XF425ESA2. If your engines are the original A version, the counter-rotating match is the LXF425ESA. See every option in our 425 HP range.

Why Counter-Rotation?

Every prop pushes the stern a little sideways as well as forward. On a boat with two or more 425 hp engines, those sideways forces are large. If all props turned the same way, the boat would pull hard to one side. With standard and counter-rotating engines working together, the forces cancel. The boat runs straight, turns evenly both ways and backs up predictably. That balance is what the Yamaha LXF425ESA2 for sale provides on the port side.

What Makes the XTO Different

The XTO Offshore was designed specifically for heavy offshore boats. Direct injection gives more efficient combustion for better power and economy. The 5.6 litre V8 produces the torque heavy hulls need to plane and hold speed in rough water. Large props with lots of blade area give strong thrust forward and in reverse. Integrated electric steering clears hydraulic plumbing off the transom. And strong charging keeps up with the big electrical loads of modern offshore boats.

Why a 35 Inch Shaft?

Very large center consoles often mount their engines high on brackets to keep the cockpit dry and give a smoother ride. To get the props deep enough to grip in big seas, they need long shafts. Measure from the mounting surface straight down to the bottom of the hull. If you get close to 35 inches, the Yamaha LXF425ESA2 for sale is the right length. Around 30 inches needs a U shaft and around 25 inches an X shaft.

Boats That Use It

• Center consoles from about 40 to 50 feet
• Large sportfishing boats
• Outboard-powered express boats and yachts
• Big catamarans with tall brackets
• Patrol, rescue and government vessels

Performance and Props

XTO-powered boats accelerate hard, cruise fast and carry heavy loads without strain. Exact performance depends on hull, weight and the number of engines. XTOs use dedicated large-diameter props. The Yamaha LXF425ESA2 for sale needs left-hand props matched to the rest of the set. Your rigger will test props in sea trials so every engine reaches its rated rpm range at full throttle with a normal load. See Yamaha’s propeller pages.

Rigging

An XTO install needs an experienced rigger. A typical setup includes a Yamaha digital control binnacle for the number of engines, digital harnesses and network parts, start/stop panels, Yamaha or compatible displays, steering controls for the integrated electric steering, independent fuel feeds with water separating filters, battery banks sized for the engines and boat systems, and matched XTO props.

Transom and Bracket Strength

Each XTO weighs close to 1,000 pounds, so a triple or quad setup puts thousands of pounds on the stern. Make sure the transom or bracket is rated for the total weight and power. Inspect it carefully, use the specified hardware and backing plates, seal every hole and re-check bolts after the first few trips and at every service.

Fuel and Maintenance

Use the octane in the owner’s manual, usually 89, with fresh fuel and no more than 10 percent ethanol. Fit a good water separating filter on every engine. Follow the owner’s manual for service intervals: oil and filter, gear oil, fuel filters and separator elements, plugs as needed, anodes, grease points and water pump impellers. Service every engine together and flush after salt water.

Handling Big XTO Boats

With digital controls and integrated steering, several XTOs make even very large boats manageable at low speed. Pivot by shifting port and starboard engines in opposite directions. Walk the stern sideways with opposite shifts and a little helm. Hold position with short bursts on each engine. Many XTO boats also use Yamaha’s joystick docking, which coordinates engines and steering automatically. At cruise, synchronisation keeps the engines matched. Practise in open water first.

Thrust Is What You Feel

Horsepower is the number people quote, but on heavy boats thrust is what you feel. The Yamaha LXF425ESA2 for sale swings a large prop with lots of blade area, gripping more water than a typical outboard prop. That gets heavy hulls onto plane quickly and keeps them there in rough seas. Strong reverse thrust also makes stopping, docking and holding position far more controlled.

Integrated Electric Steering

Traditional big outboard boats used hydraulic steering with hoses, cylinders and tie bars crowding the transom. XTOs build the steering actuator into the engine and take electronic commands from the helm. The transom is cleaner, there is less to maintain and the steering feels light and precise. On multi-engine setups the system coordinates the engines, which helps with low speed handling and joystick docking.

A Long Day Offshore

Picture a 46 foot center console with quad XTOs, two of them Yamaha LXF425ESA2 engines on the port side. You leave before dawn, sliding out of the slip on the joystick. Outside the inlet, all four V8s come up together and the big boat climbs onto plane with full tanks and a crew of eight. The 35 inch shafts keep the props deep in a building swell, and counter-rotation keeps the boat tracking straight.

You fish the canyon all day with the engines idling quietly. In the afternoon you head home into a head sea, trimmed down, holding a steady speed. Back at the marina the joystick slides the boat into its berth. Engines flushed, hours logged.

Electrical and Fuel Planning

Large XTO boats carry very heavy electrical loads. Give the engines dedicated cranking batteries, put accessories on a separate house bank and use switches or relays to protect the cranking batteries. Size cables properly, keep connections clean and tight, use dielectric grease on digital plugs and keep accessories off the engine harnesses. Every engine also needs its own fuel feed and water separating filter, so a clogged filter only affects one engine. Make sure lines and vents can supply several big V8s at cruise and carry spare filters on long trips.

How Many Engines?

Boats using 35 inch XTOs are usually large, often running triples or quads. On triples, a common layout is counter-rotation on port with standard in the centre and on starboard. On quads, the two port engines are usually counter-rotating. Builders vary, so always follow your builder’s specification and never exceed the boat’s rated horsepower and weight. The Yamaha LXF425ESA2 for sale fills the counter-rotating positions on a 35 inch A2 setup.

Engine Height, Trim and Data

Start at the builder’s recommended height and fine-tune during sea trials so the props grip in turns and rough water. At cruise, trim up until speed stops rising, keeping the bow lower in head seas. Yamaha’s displays show rpm, trim, fuel flow, hours, voltage, temperature and alarms for every engine. A clear engine page helps you catch problems early and plan fuel accurately.

Looking After Your Engines

Flush every engine with fresh water after salt use. Rinse cowlings, brackets and trim rams. Check anodes often, spray powerheads with corrosion protectant every few weeks and wax the cowlings twice a year. Keep batteries healthy and connections clean. Log hours and services for every engine. If the boat stays in the water, run the engines regularly and protect the lower units from growth as your dealer advises. A set built around the Yamaha LXF425ESA2 for sale that is looked after this way will give many seasons of strong running.

Repowering and Fleet Use

Repowering an older big boat with XTOs is a major project. Check transom or bracket strength, ratings, fuel and electrical capacity and helm space. If the boat was not built for XTO weight, talk to the builder or a naval architect first. Commercial and government fleets often standardise on one version, such as A2, to keep parts and training simple. Plan services on hours, keep parts in stock and log every engine.

Is This the Right Engine?

The Yamaha LXF425ESA2 for sale is right if your boat uses 35 inch XTOs, needs counter-rotation in this position and runs A2 versions. If your transom is 25 or 30 inches, the position needs standard rotation or your engines are A or A7 versions, another model will suit you better. Send us photos of your transom and engine labels and we will confirm the right choice before you order.

We help you confirm shaft length, rotation and version before you pay for the Yamaha LXF425ESA2 for sale. You get a written delivered price, a clear answer on warranty for your country and photos of the crate and label on request.

Why Big Boats Choose XTO

When builders design 40 to 50 foot outboard boats, they face a challenge. These hulls are heavy, they carry big fuel loads and large crews, and their owners expect them to run fast and comfortably far offshore. Older outboards could push them, but it often took four or five engines and a lot of compromise. The XTO changed that. With the Yamaha LXF425ESA2 for sale and its partners, builders can give big boats the thrust they need with fewer compromises in weight, steering and handling.

Owners notice the difference straight away. Heavy boats get onto plane without the long, nose-high struggle older setups sometimes had. They hold speed in rough water instead of bogging down. They back up and dock with more control thanks to strong reverse thrust and integrated steering. And the engines run quietly enough that long days offshore are far less tiring.

For anyone running or building a big boat on 35 inch brackets, those are the reasons the Yamaha LXF425ESA2 for sale makes sense. It is not just about the 425 horsepower figure. It is about how the whole system works together to make a large boat easier and more pleasant to run.

Running Efficiently

Fuel is the biggest running cost on any big boat. Use fuel flow data to find the speed where your boat runs most efficiently, since most large hulls have a clear sweet spot. Trim up until speed stops rising. Keep the bottom clean, because growth on a big hull costs a lot of speed and fuel. Keep props matched and undamaged. Keep the engines synchronised at cruise, and carry only what you need. These habits save real money over a season and extend your range, which adds a safety margin offshore.

Getting Home on Fewer Engines

Multiple XTOs give real redundancy. If one engine has a problem, tilt it up to cut drag and run home on the others at a sensible speed. Practise this on a calm day so you know how your boat behaves, and plan fuel with extra margin because running slower can raise consumption per mile. With a set that includes the Yamaha LXF425ESA2 for sale, one problem does not have to end your day in trouble.

Living With XTO Power

Owners usually find XTOs easy to live with. They start readily, idle quietly and run long days without fuss. Routine care is straightforward: flush after use, keep an eye on oil, keep anodes fresh and service on schedule. Most problems on big boats come from bad fuel, weak batteries or corroded connections rather than the engines themselves. Look after those basics and the Yamaha LXF425ESA2 for sale will give you many years of dependable power.

A Season on a Big Sportfisher

Many owners who buy a Yamaha LXF425ESA2 for sale run large sportfishing center consoles that cover a lot of miles in a season. Picture one of those boats through a typical year. In spring, after a winter on the hard, the engines get fresh oil, new anodes and a check-over before launch. The first trips are short shakedown runs to make sure the props, trim and electronics are all set right.

Summer is the busy season. The boat heads out most weekends and plenty of weekdays, often running 60 to 80 miles each way to the canyons. The engines work hard, carrying full tanks, big crews and heavy tackle at fast cruising speeds. After every trip they get a fresh water flush and a rinse, and every so often the owner checks the oil and the anodes. Around mid-season, the engines reach their service interval, and the dealer does a full service on all four at once.

Autumn brings some of the best fishing of the year, with cooler weather and sometimes rougher seas. The torque of the XTOs makes those days easier, holding speed into a head sea without strain. When the season ends, the boat comes out, the fuel is stabilised, the engines are serviced again and the boat is covered for winter. Thousands of miles, hundreds of hours, and the engines are ready to do it all again next year.

Common Mistakes

• Ordering the wrong shaft length for the bracket
• Putting a counter-rotating engine in a standard position
• Mixing A, A2 and A7 versions without checking
• Undersized fuel lines or battery systems
• Using props not designed for XTO engines
• Skipping fresh water flushing after salt

Avoid these and your Yamaha LXF425ESA2 for sale will slot neatly into your boat and run as Yamaha intended.
