Honda BF350AUCDA 350HP – iST 30″ Shaft Counter Rotation in White

Honda BF350AUCDA 350HP V8 iST

The Honda BF350AUCDA is an White 350HP V8 iST outboard representing a high-output high-displacement power and digital sophistication in the US offshore market. Powered by a 5.0L 32-valve SOHC engine architecture and a dry weight of 782 lbs, this V8 provides monumental torque for heavy offshore hulls. This 30-inch extra-long shaft model is specifically designed for multi-engine arrays requiring a counter rotation left-hand drive. Our dependable outboard propulsion systems deliver the power needed for offshore dominance and professional salt-water transit. Operational peak performance for this Honda 350HP is achieved at 6000 RPM, featuring VTEC technology for maximized thermal efficiency and high-end speed. The 1.79:1 gear ratio is strategically engineered for offshore hydrodynamic efficiency and stable cruising in heavy offshore swells. Built with legendary Japanese precision, the unit includes advanced vibration dampening and integrated electric power steering compatibility for an exceptionally smooth ride in professional maritime environments.

V8 VTEC Power Architecture

This 350HP V8 iST outboard utilizes VTEC technology to shift cam profiles at high RPMs for monumental power output. This creates a flat torque curve that allows for consistent acceleration under heavy offshore boat loads. It provides the thermal efficiency and sustained high-end thrust that modern US mariners demand for offshore transit.

iST Drive-By-Wire Precision

The Intelligent Shift and Throttle system eliminates mechanical cables for a high-tech drive-by-wire experience. This helps support smooth gear engagement and precise throttle synchronization, which is critical for maneuvering large offshore vessels in busy US harbors. It represents a high-output modern maritime control and vessel safety.

30-Inch Counter Shaft

The Honda BF350AUCDA 30-inch shaft length is designed for extra-high transoms requiring deep propeller immersion and hydrodynamic grip in offshore swells. The counter rotation gearbox balances steering forces in multi-engine arrays for better tracking. This setup is ideal for large fiberglass offshore cruisers and sportfishing walkarounds.

Integrated Electric Steering

Compatible with integrated electric power steering, this V8 offers helm control regardless of vessel speed or sea conditions. It reduces operator fatigue during long-range coastal transits and improves maneuverability in tight quarters. This technology is a hallmark of Honda’s high-performance marine engineering in Japan.

Honda 5-Year Protection

Honda Marine protects this 350HP unit with a comprehensive 5-year limited warranty for American boat owners. This factory-backed coverage covers major components against manufacturing defects to helps support long-term maritime reliability. It reflects a commitment to quality and professional-grade support across the country for compatible marine applications.

Maintenance & Longevity

Routine maintenance of the 5.0L V8 cooling system is vital to prevent internal salt corrosion and overheating. Regularly inspect the wet sump lubrication system and net charging output to helps support peak mechanical protection for all internal components.Pro Tip Honda BF350AUCDA:Apply a high-quality marine wax to the White finish periodically to maintain its UV-resistant properties and prevent salt-spray staining in the intense US coastal sun.
