Description
This is a new Yamaha LXF425ESA for sale, the counter-rotating 425 horsepower XTO Offshore V8 with a 35 inch shaft, in its original A production version. It ships in its factory crate and we deliver to buyers all around the world. On big boats running original-version XTOs on tall 35 inch brackets, this is the counter-rotating engine for the port positions.
The 35 inch E shaft is the longest in the XTO family. It suits the largest outboard boats, which often mount their engines high on brackets to keep the cockpit dry and smooth the ride. The props still need to reach deep water to grip in big seas, and that is where the long shaft comes in. The leading L in the model code means the prop turns opposite to a standard engine, so it balances standard XF425s on the other side.
Below: specifications, the model code explained, matching advice, rigging, running costs, maintenance and ordering. For help with your boat, contact us.

The Model Code
The Yamaha LXF425ESA for sale reads like this: L for counter-rotation, XF for the XTO Offshore four stroke series, 425 for horsepower, E for the 35 inch shaft and SA for the model series in its original version. Without the L, the same engine would be the standard rotation XF425ESA. Change E to U for a 30 inch shaft or X for 25 inches. Later production versions carry a 2 or 7 after the A.
Matching versions keeps the control network, displays, joystick systems and coordinated steering consistent across every engine on your boat.
Matching Your Set
Before ordering, check that your transom or bracket measures about 35 inches, that the position needs counter-rotation, usually on the port side, that your other engines are the original version, and that every prop matches in size and pitch with left-hand props on counter-rotating engines. If your engines are A2 versions, choose the LXF425ESA2. Other combinations are in our 425 HP range.
Why Counter-Rotation?
A spinning prop pushes the stern sideways as well as forward. On a boat with three or four 425 hp engines, those sideways forces are enormous if every prop turns the same way. Mixing standard and counter-rotating engines cancels them out, so the boat runs straight, turns evenly and backs up predictably. The Yamaha LXF425ESA for sale provides that balance on the port side.
What Makes the XTO Different
Yamaha designed the XTO for heavy offshore boats. Direct injection improves combustion for better power and economy. The 5.6 litre V8 gives huge torque. Large props with lots of blade area provide strong thrust forward and in reverse. Integrated electric steering removes hydraulic plumbing from the transom, and strong charging keeps up with big electrical loads.
Why a 35 Inch Shaft?
Very large center consoles and sportfishing boats often mount engines high on brackets. To reach deep water with the props, they need very long shafts. Measure from the mounting surface straight down to the bottom of the hull. If you get close to 35 inches, the Yamaha LXF425ESA for sale is the right length.
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 boats accelerate hard, cruise fast and carry heavy loads without strain. The Yamaha LXF425ESA for sale needs left-hand XTO props matched to the rest of the set. Your rigger will test props in sea trials so every engine reaches its rated rpm range. See Yamaha’s propeller pages.
Rigging
An XTO install needs an experienced rigger. A typical setup includes a Yamaha digital control binnacle, 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 triples and quads put 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 re-check bolts after the first 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, and fit a water separating filter to every engine. Follow the manual’s service intervals: oil and filter, gear oil, fuel filters, plugs as needed, anodes, grease points and water pump impellers. Service every engine together and flush after salt water.

Triples and Quads
Boats using 35 inch XTOs are usually large enough for 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 and the two starboard engines standard. Builders vary, so always follow the builder’s specification. The Yamaha LXF425ESA for sale fills counter-rotating positions on a 35 inch original-version setup. Multi-engine boats also need properly planned fuel delivery, battery systems and controls, so use a rigger who has installed large XTO setups before.
Handling Big XTO Boats
With digital controls and integrated steering, multiple XTOs make very large boats easy to handle at low speed. Pivot with opposite shifts, walk the stern sideways with opposite shifts and a little helm, and hold position with short bursts on each engine. Joystick docking, common on XTO boats, coordinates engines and steering automatically. At cruise, synchronisation keeps the engines matched.
Thrust and Reverse Power
The Yamaha LXF425ESA for sale swings a large prop with lots of blade area, which grips 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 helps you stop, back into a slip and hold position over structure.

Integrated Electric Steering
Older big outboard boats used hydraulic steering, with hoses, cylinders and tie bars crowding the transom. On a quad setup, that was a lot of plumbing to look after. XTO engines, including the Yamaha LXF425ESA for sale, build the steering actuator into each engine and take electronic commands from the helm. The transom is cleaner, there is far less to maintain, and the steering feels light and precise even on a 50 foot boat. The system also coordinates multiple engines, which helps at low speed and works with joystick docking. Because the engines share this system, matching production versions is especially important.
Electrical and Fuel Planning
The biggest XTO boats carry very heavy electrical loads, often including air conditioning, gyrostabilisers, large displays and full galley equipment. Give the engines dedicated cranking batteries, put accessories on a separate house bank and protect the cranking batteries with switches or relays. Size cables properly, keep connections clean and tight, use dielectric grease on digital plugs and keep accessories off the engine harnesses. On the fuel side, give every engine its own feed and water separating filter so one clogged filter affects only one engine. Make sure fuel lines and tank vents can supply three or four big V8s at cruise, and carry spare filters on long trips.
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. On a quad setup, a clear engine page on your display makes it easy to keep track of everything and spot problems early.
Looking After Your Engines
Flush every engine after salt use, rinse cowlings and brackets, check anodes often and spray powerheads with corrosion protectant every few weeks. Wax the cowlings twice a year, keep batteries healthy and log hours and services for every engine. If the boat lives in the water, run the engines regularly and protect the lower units from growth as your dealer advises. A set built around the Yamaha LXF425ESA for sale that is looked after like this should give years of strong running.
A Long Day Offshore on Quad XTOs
Picture a 48 foot center console with quad XTOs, two of them Yamaha LXF425ESA engines on the port side. You leave before dawn, using the joystick to slide the big boat out of its slip. Outside the inlet, all four V8s come up together and the boat climbs smoothly onto plane, even with full tanks, a large crew and heavy tackle. The 35 inch shafts keep every prop deep in a rolling sea, and the counter-rotating port engines keep the boat tracking straight.
You fish the canyon all day, the engines idling quietly while the electronics run nonstop. In the afternoon the wind builds, and you head home into a head sea, trimmed down, with the torque of four big V8s holding a steady speed. Back at the marina, the joystick slides the boat into its berth. The engines are flushed and the hours logged. That is exactly the day XTO engines were designed for.
Replacing an Engine on an Early XTO Boat
Many buyers of the Yamaha LXF425ESA for sale own early XTO boats and need to replace a single engine. Matching the original version keeps the new engine working with the same controls, displays and steering as the others. Send us the model codes, serial numbers and hours of the engines you are keeping. If they are healthy, replacing one usually works well. If they are very high hours, we can discuss a full set.
Common Mistakes
- Wrong shaft length for the bracket
- Wrong rotation for the position
- Mixing versions without checking
- Undersized fuel lines or battery systems
- Using non-XTO props
- Not flushing after salt

Who Actually Needs a Counter-Rotating 425
Most people looking at a Yamaha LXF425ESA for sale already know the answer to this, but it is worth spelling out for anyone who is new to big twin or triple rigs. A counter-rotating motor spins its prop the opposite way to a standard motor. You pair it with a regular right-hand XF425 so the two props cancel out each other’s torque. The boat tracks straight, the wheel does not pull to one side at speed, and you do not have to hold trim tabs down just to keep the bow level.
If you run a single engine, you do not need this motor. Buy the standard rotation version and save yourself the headache of hunting for left-hand props. But if you have a twin, a triple or a quad setup on the transom, at least one of those motors should be counter-rotating, and on a twin it is the port side one in most installs. That is where the LXF425ESA earns its place, and it is why we keep a Yamaha LXF425ESA for sale listed next to the standard model.
We get a lot of emails from owners who lost one engine in a twin pair and only need to replace that side. That is a very common reason people search for a Yamaha LXF425ESA for sale. Matching the shaft length and the rotation matters more than anything else in that situation, so check the decal on the lower unit of the old motor or send us a photo of the serial plate and we will tell you what you have.
The 35 Inch Shaft and Why It Matters
The 35 inch shaft is the extra-extra-long version. It is built for big offshore boats with tall transoms, usually 40 feet and up, where the motors hang off a bracket or a high notch. Put a shorter shaft on a transom like that and the prop sits too close to the surface. You get ventilation in turns, blowout in a following sea, and a lot of noise without a lot of push.
Measure before you order. Run a tape from the top of the mounting bracket straight down to the bottom of the hull at the keel line, or to the lowest point of the bracket if you have one. If that number is close to 35 inches, the Yamaha LXF425ESA for sale on this page is the right length. If it is closer to 30, you want the X shaft model instead, and we have those listed too.
Do not guess on this. A wrong shaft length is the single most expensive mistake we see, because by the time the motor is hung and rigged, sending it back is a big job. A five minute measurement saves a lot of grief.
What Living With the XTO 425 Is Like
I will be honest about the size of this thing. The XTO is heavy, a little over 950 pounds depending on the shaft, and it needs a transom and a bracket rated for it. It is not a motor you bolt onto a boat that was designed for 300s and hope for the best. Talk to the boat builder or a marine surveyor first if you are repowering an older hull.
Once it is on the right boat, though, it is a pleasure. Throttle response is quick for something this big. The direct injection gives you clean starts, even in cold mornings, and the fuel burn at cruise is better than people expect from a V8 this size. The integrated electric steering means no hydraulic lines running through the boat, which cleans up the rigging and removes one more thing that leaks. It is one of the main reasons boat owners come to us looking for a Yamaha LXF425ESA for sale instead of an older hydraulic setup.
The built-in charging output is another reason people pick this motor. Offshore boats carry a lot of electronics now, plus livewells, pumps, lights and sometimes a gyro. The XTO puts out enough current to keep up with all of that while you are running, so you are not coming home with flat house batteries.
Maintenance Notes From Experience
Treat it like any big four-stroke. Change the oil and filter on schedule, check the gear lube for water or metal, and look at the anodes every few months if the boat lives in salt water. Flush it with fresh water after every trip. That last one sounds obvious but it is the habit that keeps cooling passages clear for years.
The fuel system is high pressure, so keep the water-separating filters fresh and buy fuel from places that move a lot of it. Bad fuel is the cause of most of the trouble calls on modern outboards, not the engines themselves. Running the Yamaha LXF425ESA on clean fuel with a good filter setup is the easiest way to keep it happy.
Keep the paperwork that comes with the motor. Your local Yamaha dealer will want the serial number to register warranty and to pull up service bulletins. Coverage depends on the country where the motor is installed and registered, so ask your local dealer about the terms in your area before the motor goes on the boat.
Ordering Your Yamaha LXF425ESA
Here is how buying works with us. You send a message through the contact page with the model, the quantity and your country. We come back with a delivered price that includes crating and shipping. Once you are happy with the quote, we arrange payment and get the motor moving. You get tracking as soon as it is handed to the carrier.
If you are buying a matched pair, say one standard and one Yamaha LXF425ESA for sale as a twin set, tell us in the first message. We can ship both together, which usually works out cheaper per motor and means they arrive on the same day. The same goes for triples and quads, where you might need two of the Yamaha LXF425ESA for sale on this page and two standard rotation motors.
Need props, controls or gauges as well? Ask. It is easier to sort everything in one order than to chase parts from three different places after the motors have landed. You can also browse the rest of the 425 HP Yamaha range or the full shop if you are still comparing.
