Yamaha LF300ECB2 300 HP Outboard Motor

The Yamaha LF300ECB2 (300 HP V6 Offshore) is a premium, 4.2-liter four-stroke outboard designed for serious offshore anglers and high-performance cruisers. This counter-rotation model is engineered for multi-engine setups, providing the balanced torque needed for large vessels to track straight and handle predictably in rough water.

• Massive Power-to-Weight Ratio: By utilizing Plasma-Fused Sleeveless Cylinders, Yamaha has created a 4.2L engine that is significantly lighter than previous V8 models while offering 60% harder cylinder walls for increased durability and better cooling.
• Precision Maneuvering with TERE: The Thrust Enhancing Reverse Exhaust (TERE) system keeps exhaust bubbles away from the propeller when in reverse (under 2500 RPM). This allows the prop to “bite” into clean water, giving you incredible control during tight-quarter docking or when backing down on a fish.
• Digital Command & Control: This model is fully compatible with the Helm Master® EX system, offering features like joystick maneuvering, Autopilot, and GPS-based “SetPoint” positioning.
• Effortless Maintenance: The TotalTilt™ function allows you to fully tilt the engine up or down with a simple double-tap of a button, saving time during trailering or at the end of a long day on the water

Key Specifications

• Variable Camshaft Timing (VCT): This system advances or retards camshaft timing based on engine RPM, significantly boosting low- and mid-range torque. This results in the “blistering acceleration” needed to get heavy offshore boats on plane quickly.
• Integrated Digital Electric Steering (DES): Unlike traditional hydraulic systems, DES is built directly into the engine, removing the need for external pumps, hoses, or messy bleeding procedures. It provides faster, more precise steering and only draws battery power when actively in use.
• Shift Dampener System (SDS®): Standard on this model, SDS® uses a patented rubber hub to absorb the “clunk” and vibration typically felt when shifting into gear, making your time on the water much quieter and more comfortable

• Plasma-Fused Sleeveless Cylinders: Yamaha uses a thermal fusion process to create cylinder walls that are 60% harder than steel. This eliminates heavy steel sleeves, reducing weight while improving cooling and reducing internal friction for a longer engine life.
• Dual Engine Flushing: Keeping salt and debris out of your engine is easy with both a built-in external flushing port and an optional automatic on-board system, ensuring your investment stays in peak condition with minimal effort.
