Product Description

The White Whale 300XSR is engineered to deliver uncompromising performance through its 6-cylinder V-60° DOHC engine with 24 valves and variable valve timing. Its Electronic Fuel Injection system continuously adjusts fuel delivery for precise combustion, instant acceleration, and remarkable fuel economy. The 4169 cc engine produces abundant low-end torque and sustained high-speed output, making it ideal for offshore and high-load applications. The result: maximum efficiency, smooth power curves, and clean, quiet operation.

Built using Selva’s plasma-fusion cylinder process, the 300XSR combines exceptional strength with lightweight agility. The Extra Long Shaft configuration enhances propeller immersion and stability, ensuring superior thrust and balance on deep-V hulls. Its corrosion-resistant alloy components, advanced cooling system, and reinforced gearcase guarantee durability in harsh saltwater conditions. With a dry weight of only 260 kg, it delivers an outstanding power-to-weight ratio for this class.

The integrated drive-by-wire control system gives instantaneous throttle and shift precision, free from mechanical cables. Operators benefit from effortless steering and smooth response at all speeds. The Selva Marine plug-and-play digital gauge system provides real-time performance, fuel, and diagnostic data, simplifying monitoring and maintenance. Designed for convenience and command, the White Whale 300XSR offers total control  from gentle docking to wide-open throttle cruising.
