Yamaha LF300USB2 300HP White DES Counter 30″ Outboard Motor

Yamaha 300HP LF300USB2 White DES Counter 30in

Designed for the tallest transoms on premium multi-engine offshore vessels, the Yamaha 300HP LF300USB2 features an ultra-long 30-inch shaft and counter-rotation in Pearlescent White. This 4.2L V6 Offshore engine integrates Digital Electric Steering (DES), eliminating external hydraulic lines to offer precise control and a clean aesthetic for high-end center consoles. The big-bore 4166cc architecture emphasizes hydrodynamic efficiency and massive torque, ensuring that every bit of horsepower is translated into thrust while the counter-rotating gearcase neutralizes propeller torque for a balanced driving experience in heavy sea states.

Refined for professional-grade utility, the LF300USB2 utilizes Variable Camshaft Timing (VCT) to refine air intake and maximize fuel economy across the entire RPM band. The motor is shielded by multi-stage anodic protection and specialized anti-corrosion coatings to safeguard against galvanic wear during prolonged offshore exposure. Maintenance effort is reduced by the 100-hour service schedule and conveniently located freshwater flush ports. This model features a high-output 70-amp alternator (net), providing massive power reserves to support multiple battery banks, gyrostabilizers, and high-demand tournament electronics.
