Yamaha 300HP F300USB2 White DES Digital 30in

Designed for the tallest transoms on premium offshore vessels, the Yamaha 300HP F300USB2 features a 30-inch ultra-long shaft and a premium Pearlescent White finish. Part of the legendary 4.2L V6 Offshore family, this model integrates Digital Electric Steering (DES) to provide smooth, precise control without the complexity of external hydraulic lines. The architecture emphasizes torque density and lightweight efficiency, utilizing a 24-valve DOHC design and Variable Camshaft Timing (VCT) to deliver explosive mid-range punch and top-end speed required for large offshore center consoles.

Focused on superior operational durability, the F300USB2 leverages Plasma Fusion cylinder walls for enhanced cooling and friction reduction. The chassis is shielded by multi-stage anodic protection and high-grade marine alloys to defend against oxidation during prolonged offshore service. Routine maintenance is simplified by the front-mounted freshwater flush port and easy-access internal components. This unit features a high-output 70-amp alternator (net), providing massive power reserves to maintain battery health and support high-demand tournament electronics, gyrostabilizers, and navigational safety equipment.
