Built for Offshore Boats and Large Center Consoles

The Yamaha 350hp White DEC Outboard LF350XSA2 is built for larger boats that need serious propulsion strength.

It is suitable for offshore fishing boats, large center consoles, performance cruisers, sport boats, luxury pontoons, commercial-style recreational craft, and multi-engine installations. With 350hp output, this outboard gives compatible vessels the power needed for strong acceleration, heavier loads, offshore runs, cruising performance, and confident handling.

This model is especially important for boats requiring counter left rotation, often in twin or multi-engine setups where matched rotation helps improve handling and steering balance.

For customers searching for a Yamaha 350hp counter rotation outboard, the LF350XSA2 provides the correct high-output configuration for compatible applications.

350hp Yamaha Power for Demanding Marine Performance

The Yamaha LF350XSA2 delivers 350 horsepower, placing it in a serious high-performance outboard class.

A 350hp outboard motor is commonly selected for larger hulls that need more thrust, stronger acceleration, improved load-carrying ability, and dependable power in open-water conditions. This horsepower class is especially relevant for offshore anglers, performance boaters, larger family vessels, and commercial-style recreational users.

For repower buyers, choosing the correct 350hp configuration matters. Shaft length, rotation, control type, steering compatibility, propeller selection, and rigging must all match the vessel correctly.

For buyers searching for a Yamaha 350hp outboard for sale, this white DEC counter-rotation model offers a strong premium setup.

Digital Electronic Controls for Precise Operation

The Yamaha 350hp White DEC Outboard LF350XSA2 features Digital Electronic Controls, often referred to as DEC.

Digital Electronic Controls help provide smooth throttle response, refined shifting, cleaner helm operation, and more precise engine control compared with traditional mechanical cable systems.

For a 350hp outboard, precise control is especially important. Smooth throttle and shift response can improve docking, marina movement, low-speed control, acceleration, cruising, and multi-engine maneuvering.

Electronic controls are also valuable in twin and multi-engine setups where synchronized operation and consistent response matter.

For customers searching for a Yamaha DEC outboard, the LF350XSA2 gives buyers a modern electronic-control configuration.

Counter Left Rotation for Matched Engine Setups

The Yamaha LF350XSA2 uses counter left rotation, making it especially useful for twin or multi-engine applications.

Counter rotation helps balance propeller torque when paired with a standard-rotation outboard. In many twin-engine installations, one engine rotates standard and the other rotates counter. This setup can improve tracking, reduce steering torque, support better docking behavior, and help the vessel feel more balanced.

Rotation is one of the most important buying details when replacing an outboard in a multi-engine setup. Installing the wrong rotation can affect handling, propeller compatibility, and overall performance.

For buyers searching for a Yamaha 350hp counter left rotation outboard, this LF350XSA2 model provides the required configuration.

25-Inch X-Long Shaft Fitment

The Yamaha 350hp White DEC Outboard LF350XSA2 features a 25-inch X-long shaft, making it suitable for compatible taller-transom boats.

Correct shaft length is critical in high-horsepower applications. The shaft length affects lower-unit position, propeller depth, water flow, cooling water intake, trim response, thrust, and handling.

A 25-inch shaft is commonly used on larger offshore boats, center consoles, cruisers, and multi-engine transoms requiring X-long fitment.

Before ordering, buyers should confirm transom height, engine mounting position, bracket setup, engine spacing, steering layout, and propeller requirements.

For customers searching for a Yamaha 350hp 25-inch shaft outboard, the LF350XSA2 provides the correct long-transom configuration for compatible vessels.

White Finish for a Premium Look

The Yamaha 350hp White DEC Outboard LF350XSA2 features a clean white finish, giving the transom a modern and premium appearance.

White outboards are popular on large center consoles, offshore fishing boats, luxury pontoons, sport boats, and cruisers because they pair well with white hulls, bright decks, and high-end marine styling.

For many buyers, appearance matters alongside performance. A white 350hp Yamaha outboard can help create a cleaner, more coordinated look on the boat.

For customers searching for a white Yamaha 350hp outboard, the LF350XSA2 offers both premium styling and serious high-output capability.

Electric Start for Convenient Helm Operation

The Yamaha LF350XSA2 includes electric start, supporting convenient operation from the helm or control station.

Electric start is essential in a high-horsepower outboard class because these engines are designed for remote helm operation and regular marine use. It supports easier starting during offshore trips, fishing days, marina movement, cruising, launching, docking, and repeated operation.

In multi-engine setups, dependable electric starting is especially important because both engines must be ready for safe and efficient operation.

Buyers should confirm battery capacity, wiring setup, DEC rigging compatibility, ignition configuration, and helm integration before installation.

Power Trim and Tilt for Better Control

The Yamaha 350hp White DEC Outboard LF350XSA2 includes power trim and tilt, giving the operator convenient control over engine angle and lifting position.

Power trim helps adjust boat running attitude while underway. Correct trim can improve acceleration, bow lift, ride comfort, speed, steering feel, and fuel efficiency depending on vessel design, sea conditions, load, and operating speed.

Power tilt allows the outboard to be raised for trailering, docking, storage, shallow-water positioning, lower-unit inspection, and maintenance access.

For a 350hp outboard, power trim and tilt is essential because manual lifting is not practical and trim adjustment plays a major role in performance and handling.

Ideal for Repower and Multi-Engine Installations

The Yamaha 350hp White DEC Outboard LF350XSA2 is a strong choice for compatible repower projects and matched multi-engine setups.

Repowering with a high-output outboard requires careful planning. Buyers must confirm shaft length, rotation, steering system, DEC control compatibility, propeller selection, mounting hardware, battery setup, engine spacing, and transom rating.

This model is especially valuable when the vessel needs a counter left rotation Yamaha 350hp engine to match an existing or paired standard-rotation motor.

For boatyards, marine dealers, and performance-focused boat owners, the LF350XSA2 provides a specific and premium Yamaha configuration for serious installations.

Why the Yamaha LF350XSA2 Is a Smart Choice

The Yamaha 350hp White DEC Outboard LF350XSA2 stands out because it combines 350hp Yamaha power, Digital Electronic Controls, electric start, 25-inch X-long shaft fitment, power trim and tilt, counter left rotation, and premium white styling.

Many buyers in this category need a very specific outboard configuration. Horsepower alone is not enough. The engine must match the boat’s control system, shaft length, rotation, steering setup, propeller requirements, and installation plan.

The Digital Electronic Controls support precise helm response, while counter left rotation makes this model ideal for matched twin or multi-engine applications. The 25-inch shaft supports compatible taller transoms, and the white finish gives the engine a clean, modern appearance.

For customers searching for a Yamaha 350hp White DEC Outboard LF350XSA2 for sale, this model is a premium high-output choice.
