Honda BF350AXCDA 350HP V8 iST
The Honda BF350AXCDA is an 350HP V8 iST outboard designed to deliver uncompromising thrust for professional multi-engine offshore vessels in the US market. Utilizing a 5.0L displacement and a dry weight of 765 lbs, this silver motor maximizes its power-to-weight efficiency for high-performance applications. The 25-inch long shaft length is optimized for counter rotation, making it a critical component of dependable outboard propulsion systems used in dual-engine boat configurations. Operational peak for this Honda 350HP is maintained between 5000 and 6000 RPM. The 1.79:1 gear ratio is strategically designed to improve the torque curve for faster planing and superior hole-shot performance in heavy coastal swells. Engineered in Japan, this corrosion-resistant outboard includes advanced vibration dampening for the comfort required during rigorous offshore salt-water excursions across the American maritime market.
V8 VTEC Power
This VTEC-equipped V8 engine uses variable timing to provide high-end speed without sacrificing low-end trolling performance. This results in superior thermal efficiency and a versatile power band. It remains a premier choice for US offshore mariners marine power delivery.
Fuel Induction Precision
The fuel induction system precisely manages the air-fuel mixture to optimize performance and reduce overall consumption. This helps support instant throttle response and consistent power delivery during high-speed runs through coastal inlets. It is engineered for the rigors of American saltwater environments.
Counter Rotation Shaft
The 25-inch long shaft features a counter rotation gearbox that negates the sideways pull of a standard propeller. This improves hydrodynamic tracking and steering ease on large dual-engine vessels. It is specifically designed for high-performance requirements on offshore fiberglass hulls.
Digital Helm Integration
NMEA 2000 certification helps support the engine communicates vital data directly to the boat’s electronic helm displays. Captains can monitor battery voltage and RPM in real-time. This level of data integration is essential for safe and efficient US offshore maritime management.
Five Year Coverage
Backed by a 5-year limited warranty, this Honda BF350AXCDA 350HP provides long-term security for US boat owners. This comprehensive coverage helps support access to genuine parts and expert factory service nationwide. It reflects a commitment to durability in professional and commercial maritime sectors.
Multi-Engine Craft Match
This counter-rotation V8 is the ideal partner for a standard-rotation engine on large offshore center consoles. It provides the high-torque thrust necessary for navigating coastal inlets and heavy offshore swells. It is a preferred solution for commercial boaters and recreational anglers.
Maintenance & Longevity
Consistent maintenance of the 5.0L V8 oil levels and filter quality is essential for long-term engine health. Always flush the cooling system thoroughly after saltwater outings to maintain the unit’s corrosion-resistant properties.Pro Tip from the Shop:Inspect and lubricate the counter-rotation gearbox seals every 100 hours to helps support smooth gear engagement and prevent salt-water intrusion during high-speed offshore transit.
