Yamaha LF300UCB2 300HP White Counter 30″ Outboard Motor

Yamaha 300HP LF300UCB2 White Counter 30in

Engineered for the tallest transoms on premium offshore vessels, the Yamaha 300HP LF300UCB2 features a 30-inch ultra-long shaft and counter-rotation in a Pearlescent White finish. This 4.2L V6 powerhead is optimized for multi-engine configurations, neutralizing propeller torque to provide exceptional stability and tracking for large deep-V hulls. The architecture emphasizes hydrodynamic efficiency and torque density, utilizing Variable Camshaft Timing (VCT) to maximize air intake and mid-range punch, ensuring that energy is efficiently translated into thrust even in turbulent American coastal waters.

Refined for professional-grade utility, the LF300UCB2 leverages advanced Electronic Fuel Injection (EFI) to coordinate the air-fuel mixture for immediate throttle response and consistent ignition. The engine is shielded by specialized marine-grade alloys and multi-stage anodic protection to mitigate galvanic wear during prolonged offshore exposure. Ownership effort is reduced by the 100-hour service schedule and the integrated TotalTilt system for easy engine management. This model features a high-output 70-amp alternator (net), ensuring massive power reserves for high-demand tournament electronics, gyrostabilizers, and navigational arrays.
