Yamaha LF300XCB2 300HP – Counter Rotation Digital Control 25-Inch

Yamaha LF300XCB2 300HP White DEC

The Yamaha LF300XCB2 300HP outboard motor represents a high-output luxury offshore propulsion, featuring an advanced V6 4.2L 24-valve DOHC engine architecture in a stunning Pearlescent White finish. This powerhead maintains a dry weight of 562 lbs to helps support an power-to-weight ratio for premium multi-engine vessels requiring balanced thrust. Its 25-inch long shaft and counter-rotation gearcase are specifically designed for advanced outboard engine technology for consistent propeller immersion and stable hydrodynamic thrust during oceanic transits.

The recommended full-throttle operating range for the LF300XCB2 300HP is a wide 5000-6000 full-throttle RPM range using Digital Electronic Control (DEC) and a Precision Multi-Point EFI system. The specialized 1.75:1 gear ratio effectively translates engine energy into torque for rapid hull planing without hesitation. US offshore boaters consistently depend on this Japanese-engineered platform for its reliable operation and the sleek aesthetic of a white offshore power plant.

White V6 Performance Excellence

The LF300XCB2 features a stunning Pearlescent White finish to provide a high-end aesthetic match for luxury center consoles and high-performance hulls. Its robust 24-valve V6 configuration maximizes air intake to helps support rapid and responsive hole-shot acceleration under various loads. Luxury boat owners experience smooth power delivery and reduced vibration when cruising through technical coastal waterways at high speed with digital precision and balanced torque.

Precision Digital Interface

The LF300XCB2 utilizes Digital Electronic Control (DEC) to provide a smooth and cable-free throttle and shifting experience at the helm. This system is fully compatible with modern offshore rigging for advanced vessel positioning and synchronization in multi-engine setups. Captains gain control of multiple engine configurations for a complete and modern helm solution on luxury offshore vessels.

DOHC 24-Valve Architecture

This 300HP engine features a Double Overhead Cam (DOHC) design with four valves per cylinder to maximize air intake and exhaust efficiency. This mechanical design helps support a wider power band and higher torque output, allowing the engine to react instantly to throttle changes. You gain the refined performance needed for high-speed coastal cruising and technical maneuvering in heavy offshore conditions.

Balanced Counter-Rotation

The LF300XCB2 features a specialized counter-rotation gearcase that spins the propeller in a left-hand direction to neutralize torque pull. When paired with a standard rotation motor, this configuration helps support the vessel tracks straight and true with minimal steering effort from the captain. Boaters experience significantly improved stability and reduced operator fatigue during long oceanic crossings.

Offshore Power Delivery

The specialized 1.75:1 gear ratio provides the mechanical leverage needed to push heavy displacement hulls and maintain planing speeds in rough water. This calibration helps support the motor can effectively handle the weight of large offshore tenders and performance center consoles. Owners benefit from consistent acceleration and the power required to navigate through challenging coastal inlets with full confidence.

Routine Maintenance Protocol

This Digital V6 engine is built with high-quality sacrificial anodes to prevent destructive galvanic corrosion daily in saltwater coastal environments. Regular maintenance of the power trim and tilt system and cooling passages helps support smooth engine operation in harsh saltwater conditions.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
