The Honda BF350AXDA represents a historic breakthrough in marine propulsion as Honda’s first-ever V8 production outboard engine, delivering an extraordinary 350 horsepower that redefines performance expectations on the water. This flagship outboard combines Honda’s legendary automotive engineering heritage with purpose-built marine durability, creating an unmatched boating experience that delivers premium power, unparalleled performance, and extraordinary reliability.
Powered by an advanced 4-stroke SOHC V8 engine with 32 valves and 4952cc displacement, the BF350AXDA generates massive torque with smooth, refined power delivery across its entire operating range. Honda’s exclusive VTEC technology optimizes valve timing to provide broader torque curves and enhanced fuel efficiency, while BLAST (Boosted Low Speed Torque) technology aggressively advances the ignition curve for dramatically improved holeshots that get hulls on plane faster than competitors.
The extra-long 25-inch shaft length makes this outboard perfectly suited for a wide range of vessels with standard transom heights, including center consoles, bay boats, sportfishing boats, and performance vessels where the X-type configuration provides optimal propulsion positioning. The standard rotation configuration offers maximum versatility for single-engine applications or as the primary engine in dual-outboard setups, ensuring compatibility with most vessel designs and repower requirements.
Advanced iST (Intelligent Shift and Throttle) drive-by-wire technology delivers effortless, precise control with superb shift and throttle response. This sophisticated electronic system provides smooth, intuitive operation that makes docking and close-quarters maneuvering remarkably easy, while supporting integration with advanced helm electronics and joystick steering systems like the Optimus 360 by Dometic for ultimate boat control and maneuverability.
The BF350AXDA incorporates Honda’s innovative Lean Burn Control technology, which optimizes fuel efficiency by allowing combustion on leaner air-fuel mixtures without sacrificing performance. Combined with programmed fuel injection and microcomputer-controlled ignition, this outboard delivers exceptional fuel economy while meeting stringent emission standards and running efficiently on 86-octane fuel.
With its robust 93-amp alternator providing 70 amps of charging capacity plus AMP+ electronic load management, the BF350AXDA easily powers today’s sophisticated onboard electronics, navigation systems, fish finders, and accessories. The classic Aquamarine Silver finish provides timeless marine aesthetics that complement any vessel’s styling while showcasing Honda’s commitment to both traditional marine beauty and cutting-edge performance.
Built with automotive-grade precision using the same crankshaft alloy as Acura’s NSX supercar and backed by Honda’s industry-leading True 5 Year transferable warranty, the BF350AXDA offers legendary reliability and peace of mind. This groundbreaking V8 outboard transforms every boating experience, delivering the perfect combination of raw power, refined control, and unwavering dependability that only Honda’s revolutionary marine engineering can provide, setting new standards for what’s possible in outboard propulsion.
