Yamaha 350HP LF350UCC – V8 Counter 30in Shaft

Yamaha 350HP LF350UCC V8 Counter 30in Shaft

The Yamaha 350HP LF350UCC is a robust 5.3L V8 outboard featuring counter-rotation and a 30-inch ultra-long shaft, designed for the tallest transoms on heavy offshore vessels. Utilizing a 32-valve DOHC architecture, this engine provides massive displacement and torque density, delivering the “big block” muscle required to move large center consoles and coastal cruisers. The mechanical soul of the F350 platform focuses on structural integrity and smooth power delivery, ensuring consistent ignition and high-performance thrust even when navigating turbulent American coastal waters with a full load.

Refined for offshore reliability, the LF350UCC features Multi-Point Precision Fuel Injection and Variable Camshaft Timing (VCT) to optimize torque across the entire power band. The motor is protected by specialized marine-grade alloys and Yamaha’s proprietary multi-stage anti-corrosion system to combat galvanic oxidation in saltwater environments. Maintenance is simplified through the front-mounted freshwater flush port and easy-access service points for routine checks. This model includes a high-output 50-amp alternator, providing a stable charging system for high-demand tournament electronics, livewells, and navigational safety gear.
